Brian Dean’s Backlinko technical SEO resources have become a go-to reference for anyone serious about getting their website to perform well in search results. His guides break down complex concepts, crawlability, site speed, structured data, indexation, into clear, actionable steps that actually make sense. But knowing what technical SEO involves and knowing how to implement it on your own site are two very different things.
That’s exactly the gap this article fills. We’ve pulled together the most useful strategies, checklists, and best practices from Backlinko’s technical SEO teachings and organized them into a single, practical resource. Whether you’re auditing your site for the first time or tightening up an existing setup, you’ll find specific steps you can act on right away.
At Avatar Website Design, we build websites for small businesses with technical SEO baked in from the start, mobile-responsive design, clean site architecture, and fast load times aren’t afterthoughts for us. They’re part of the foundation. We wrote this guide because we believe every business owner should understand what’s happening under the hood of their website, even if they’re not the one turning the wrenches. So let’s get into the full breakdown of Backlinko’s approach to technical SEO and how you can put it to work.
What people mean by Backlinko technical SEO
When someone searches for Backlinko technical SEO, they’re usually looking for something specific: Brian Dean’s structured approach to the behind-the-scenes work that helps search engines find, crawl, and understand your website. Technical SEO isn’t about writing content or building links. It’s about making sure your website’s foundation is solid enough for search engines to process it correctly and rank it accordingly. Think of it as the plumbing and wiring inside a house: visitors rarely see it, but everything breaks down without it.
Brian Dean’s approach to the technical layer
Brian Dean built Backlinko into one of the most-referenced SEO resources online by doing something that many other sites avoided: explaining complex technical topics with real examples and clear, numbered steps rather than vague advice. His technical SEO guides don’t assume you have a computer science degree. They walk you through exactly what to check, what to fix, and why each fix matters for your search rankings.
Backlinko’s value isn’t in covering new ground. It’s in making the existing ground far easier to walk on.
His framework treats technical SEO as a prerequisite. Before you invest time in content or link building, your site needs to pass a baseline of technical requirements that allow search engines to do their job. Without that foundation, even strong content can get buried in search results where no one ever finds it.
The core areas Backlinko focuses on
Backlinko’s technical SEO resources consistently cover the same set of core areas. Understanding what those are helps you know exactly what you’re working toward when you follow their guidance:
- Site architecture: How your pages link to each other and how deep they sit from the homepage
- Crawlability: Whether search engine bots can actually reach and read your pages without running into dead ends
- Indexation: Which pages Google stores in its index and which ones it skips or ignores
- Page speed and Core Web Vitals: How fast your pages load and how stable the layout stays during that process
- Mobile-friendliness: Whether your site functions properly on phones and tablets, not just desktop screens
- HTTPS and security: Whether your site uses a secure, encrypted connection for visitors
- Structured data: Additional markup that helps search engines understand the context behind your content
These aren’t abstract concepts. Each one connects directly to whether your pages appear in search results and where they rank once they do.
Why Backlinko’s framing matters for small businesses
Most small business owners don’t have a developer available to handle technical fixes on demand. That’s where Backlinko’s plain-language explanations become genuinely useful. Brian Dean’s guides explain not just what to do, but what the problem actually looks like in the real world and what happens to your rankings if you leave it unaddressed.
For example, a small business site with duplicate pages caused by URL parameters might be losing crawl budget without the owner ever realizing it. A Backlinko-style audit walks you through spotting that issue, understanding why it hurts performance, and fixing it in a way that doesn’t accidentally break other parts of your site. That kind of practical, step-by-step guidance is why so many people specifically seek out his approach when they want to learn and implement technical SEO rather than just read surface-level summaries of it.
Understanding this framing also helps you prioritize. You won’t try to fix everything at once. Instead, you’ll work through a logical sequence that addresses the highest-impact problems first and builds toward a technically sound site that search engines can rely on.
Why technical SEO still drives rankings in 2026
Some people assume that technical SEO peaked years ago and that AI-generated content and link authority now do all the heavy lifting. That assumption is wrong. Search engines in 2026 are processing more pages than ever, and the sites that earn consistent rankings are the ones that make Google’s job easy. If your site has crawl errors, slow load times, or poor mobile performance, those problems drag your rankings down regardless of how good your content is.
Google’s systems still depend on crawlability
Google cannot rank a page it cannot read. Every time Google sends a crawler to your site, it has a limited amount of resources to spend before moving on. If your pages are buried deep in your site structure, blocked by incorrect robots.txt rules, or returning redirect chains, the crawler spends its budget on the wrong things and misses your most important content entirely. Fixing these problems is exactly what Backlinko technical SEO training emphasizes as the starting point for any serious optimization effort.
A page that Google can’t crawl effectively might as well not exist.
Googlebot’s behavior is documented in detail by Google’s own Search Central guidelines, and the pattern is clear: accessible, well-structured pages get indexed faster, re-crawled more often, and ranked more reliably than pages that create friction during the crawl process.
Core Web Vitals connect directly to ranking signals
Google confirmed Core Web Vitals as part of its page experience ranking signals, and those metrics measure real-world performance: how fast your largest content element loads, how much your layout shifts as the page renders, and how quickly your page responds to the first user interaction. A slow, unstable page creates a measurable negative experience that Google’s systems are specifically designed to penalize.
These aren’t soft signals. Sites with poor Core Web Vitals scores consistently underperform against competitors with faster, more stable pages, even when the content quality is comparable.
Technical debt compounds over time
Every unfixed technical issue you leave on your site adds up. Duplicate pages waste crawl budget. Missing canonical tags confuse indexation. Uncompressed images slow load times. None of these problems show up on the surface of your website, but each one quietly reduces your ability to rank. Addressing technical debt systematically and early prevents small issues from stacking into a serious ranking penalty later.
How to use Backlinko’s technical SEO framework
The Backlinko technical SEO framework isn’t a one-time fix. It’s a repeatable process that walks you through identifying problems, prioritizing them, fixing them in the right sequence, and then cycling back to check your work. Before you touch a single setting on your site, you need a clear picture of where your technical problems actually live and which ones are costing you the most in search performance.
Start with a full site audit
Your first step is running a complete crawl of your site using a tool that mimics how Google moves through your pages. This surfaces broken links, redirect chains, missing meta tags, duplicate titles, slow pages, and indexation issues all at once. Without this baseline, you’re guessing about what needs fixing instead of working from evidence.
An audit isn’t just a report. It’s the map you use to navigate every fix that follows.
Once the crawl is complete, export the results and group the issues by category: crawlability problems, indexation errors, speed issues, and content structure gaps. That grouping turns a long list of errors into a manageable work plan you can move through systematically.
Work through issues in priority order
Not every technical problem carries the same weight. Crawl errors and indexation blocks sit at the top of the priority list because they prevent Google from accessing your content entirely. Fix those first. Then move to performance issues like slow page speed and poor Core Web Vitals, which affect both rankings and the experience visitors have on your site. Structured data and minor tag fixes come last.
Backlinko’s approach reinforces this sequence consistently because it reflects how search engines actually evaluate your site. Google can’t reward fast pages it never crawled, and it can’t rank well-structured content it hasn’t indexed. The order matters more than most people realize.
Treat the framework as an ongoing process
Your site changes over time. New pages get added, plugins get updated, redirects accumulate, and technical debt quietly builds back up if you’re not watching for it. Running a technical audit on a regular schedule, at minimum once per quarter, keeps your site in the shape that search engines expect.
Set a recurring reminder to re-crawl your site and review the same core categories you checked the first time. Small issues caught early take minutes to fix. The same issues ignored for six months can take weeks to unravel.
Build a flat site structure that crawls well
Your site structure determines how efficiently Google moves through your pages. A flat site structure keeps every important page within three to four clicks of your homepage, which means crawlers reach your content quickly without burning through their crawl budget on unnecessary detours. This is one of the first areas Backlinko technical SEO guides address because a poor structure creates a ceiling on how well your site can perform, no matter how strong your content is.
A page buried six clicks deep from your homepage is a page Google may never bother to crawl.
Keep pages close to the homepage
The fewer clicks it takes to reach any given page from your homepage, the more crawl authority that page inherits from your root domain. When your site grows, it’s easy to let categories, subcategories, and subfolders stack on top of each other until important pages end up several levels deep. That depth signals to search engines that those pages are low priority, and Google’s crawler treats them accordingly.
A practical way to flatten your structure is to audit your current URL paths and count the folder levels. If a product or service page lives at /category/subcategory/sub-subcategory/page, you’re adding friction that hurts both crawlability and user navigation. Restructuring those URLs to sit at /category/page or even /page directly reduces that friction and makes every link pointing to that page more valuable in the eyes of search engines.
Use internal links to pass authority
Internal links are how crawl authority flows through your site. When your homepage links to your most important service or category pages, and those pages link to supporting content, you create a clear pathway for both users and search engines to follow. Every internal link you add is a signal about which pages matter most on your site.
Review your existing content and look for pages that have few or no internal links pointing to them. These are called orphan pages, and Google rarely prioritizes crawling them because nothing connects them to the rest of your site. Adding relevant internal links from high-authority pages to your orphan pages pulls them back into your crawl structure and gives them a real chance of appearing in search results. Even two or three well-placed internal links can make a measurable difference in how often Google revisits and re-indexes those pages.
Control crawling and indexing the right way
Crawling and indexing are two separate processes, and confusing one for the other leads to real mistakes. Crawling is when Google’s bot visits your pages. Indexing is when Google decides to store and potentially rank those pages. You can block crawling without affecting indexation, and you can allow crawling while still blocking indexation. Getting this distinction right is a core part of what Backlinko technical SEO frameworks teach, because misapplying these controls can quietly remove your most important pages from search results without any obvious warning signs.
Blocking the wrong pages from crawlers or the index is one of the easiest ways to sabotage your own rankings without realizing it.
Use robots.txt to guide crawlers
Your robots.txt file tells search engine bots which sections of your site they’re allowed to visit. It sits at your root domain and loads before a crawler goes anywhere else on your site. The key rule here is that robots.txt controls crawling, not indexing. If you block a page in robots.txt, Google cannot crawl it, but it may still index the page based on external links pointing to it from other sites.
Use robots.txt to block areas that have no business appearing in search results: admin pages, login portals, internal search result pages, and staging environments. Leave your core content pages, service pages, and landing pages completely open so crawlers can reach them without restriction. Check your robots.txt file whenever you launch a redesign or add new site sections, because a misplaced disallow rule can take entire directories offline from Google’s perspective in a single push.
Set canonical tags to consolidate index signals
A canonical tag is a line of code in your page’s header that tells Google which version of a page you want treated as the primary one. This matters whenever multiple URLs load the same or very similar content, which happens more often than most site owners expect. Session IDs, tracking parameters, and print-friendly versions of pages all create duplicate URL variations that split your indexing signals unless you consolidate them with canonicals.
Place a self-referencing canonical tag on every page of your site, including pages that don’t have obvious duplicates. This signals to Google that you’ve intentionally chosen that URL as the definitive version. When duplicate versions exist, point all canonical tags to the single URL you want ranked. That consolidation pushes the full weight of any links and crawl signals into one page rather than diluting them across several.
Clean up duplicate and thin pages
Duplicate and thin pages are two of the most common problems Backlinko technical SEO guides flag during site audits, and both quietly drain the ranking power your site builds over time. Duplicate pages split your index signals across multiple URLs instead of concentrating them on one, while thin pages give Google almost nothing useful to evaluate. Left unaddressed, either issue tells search engines that your site has low-quality, redundant content, and that perception directly affects how often your pages appear in search results.
Identify and fix duplicate content
Duplicate content doesn’t always look obvious from the outside. Your site might serve the same page at both www and non-www versions, or at HTTP and HTTPS simultaneously. Category filters, sorting parameters, and pagination can generate dozens of near-identical URLs without any deliberate action on your part. Each of those variations competes with the original, confusing Google about which version deserves to rank.
When Google finds multiple versions of the same page, it picks one to index, and it doesn’t always choose the one you want.
Start by crawling your site and grouping pages with matching or near-matching title tags and content. For URL variations caused by parameters, use Google Search Console’s URL parameters tool to tell Google how to handle them. For structural duplicates, apply canonical tags pointing to the definitive version. If a duplicate URL serves no purpose at all, redirect it to the correct page with a 301 permanent redirect so every signal pointing to that URL consolidates on the page you actually want ranked.
Handle thin pages before they cost you rankings
A thin page is any page that provides little to no substantive value to the person reading it. Placeholder pages, tag archive pages with one or two posts, boilerplate location pages that repeat the same paragraph with only a city name changed, and stub pages left over from old site sections all fall into this category. Google’s quality systems evaluate these pages and factor them into its overall assessment of your site’s content quality.
You have three options when you find a thin page: expand it with genuinely useful content, consolidate it by merging it into a stronger related page with a redirect, or remove it and redirect the URL entirely. The right choice depends on whether the page serves a real purpose. Thin pages that exist only to target a keyword without helping the reader should be removed or merged, not padded with filler text to hit an arbitrary word count.
Improve speed and Core Web Vitals
Page speed and Core Web Vitals sit near the top of any Backlinko technical SEO checklist because Google has built them directly into its ranking systems. Slow pages frustrate real visitors and signal to Google that your site delivers a poor user experience, both of which hurt your rankings. The good news is that most speed problems come from a small set of causes you can identify and fix without touching a single line of custom code.
Target the three Core Web Vitals metrics
Google measures page experience through three specific signals. Largest Contentful Paint (LCP) measures how long it takes for the biggest visible element on your page, usually a hero image or heading block, to fully load. Cumulative Layout Shift (CLS) measures how much your page layout jumps around as elements load in. Interaction to Next Paint (INP) measures how quickly your page responds after a user clicks or taps something. Each metric has a threshold Google uses to classify your page as good, needs improvement, or poor.
A page that passes all three Core Web Vitals thresholds consistently outperforms one that fails them, even when the content quality is equal.
You can check your real-world scores inside Google Search Console under the Core Web Vitals report. That report shows which pages are failing and which specific metric is causing the problem, giving you a concrete starting point rather than a vague list of performance complaints.
Fix the most common speed problems first
Most slow sites share the same set of problems. Uncompressed images are the single biggest culprit. Serving large, unoptimized image files adds seconds to your LCP score and bloats every page they appear on. Convert images to modern formats like WebP, set explicit width and height attributes to prevent layout shifts, and use lazy loading on images below the fold so the browser prioritizes visible content first.
Beyond images, render-blocking JavaScript delays how quickly your page becomes usable. Move non-critical scripts to load after the main content renders. Enable browser caching so returning visitors load your pages faster. Use a content delivery network to serve your files from a server closer to each visitor’s physical location. These fixes together move the needle on all three Core Web Vitals metrics and give your pages a measurable advantage in Google’s ranking evaluation.
Make your site mobile-friendly and secure
Mobile-friendliness and HTTPS aren’t optional extras in a Backlinko technical SEO framework. Google runs on a mobile-first index, which means it crawls and evaluates your site based on the mobile version before it ever looks at the desktop version. If your mobile experience is broken or your connection is insecure, you’re starting every ranking competition at a disadvantage before a single visitor even arrives.
Test and fix your mobile experience
Google’s mobile-first indexing means your mobile layout is the version that actually matters for rankings, not the polished desktop version you may have spent more time building. A responsive design adapts your page layout to fit any screen size automatically, so users on phones and tablets see the same content without needing to pinch, zoom, or scroll horizontally to read anything.
If your desktop site looks great but your mobile layout is broken, Google ranks the broken version.
You can check your current mobile performance using Google Search Console’s Mobile Usability report, which flags specific issues like text that’s too small to read, clickable elements placed too close together, and content wider than the screen. Fix these problems one by one. Make sure your font sizes are large enough to read without zooming, your buttons have enough spacing to tap accurately, and no content overflows the viewport width. These fixes directly improve how Google evaluates your pages and how real visitors experience them on their phones.
Switch to HTTPS and keep it clean
HTTPS encrypts the connection between your site and every visitor, and Google has used it as a ranking signal since 2014. Any site still running on HTTP in 2026 is signaling to both Google and users that the connection isn’t secure. Browsers label HTTP pages as "Not Secure" in the address bar, which reduces trust and increases the chance that visitors leave before reading anything.
Installing an SSL certificate and forcing all traffic through HTTPS is the baseline requirement. Once you’ve made that switch, check that your entire site redirects consistently from HTTP to HTTPS and from non-www to www, or the reverse, with a single 301 redirect rather than a chain. Mixed content errors, where HTTPS pages load resources like images or scripts over HTTP, break the secure connection and need to be corrected by updating every insecure resource URL to its HTTPS equivalent.
Add structured data that earns rich results
Structured data is code you add to your pages that helps search engines understand the specific meaning behind your content, not just the words on the page. When Google can read that a page is a product listing, a business address, a recipe, or a how-to guide, it can present that page in richer, more prominent formats in search results. These enhanced results, called rich results, take up more visual space on the page and tend to attract more clicks than standard blue links. Every Backlinko technical SEO guide covers structured data as a priority because it directly improves how your pages appear to searchers, not just whether they rank.
Structured data doesn’t guarantee rich results, but skipping it guarantees you’ll never earn them.
Choose the right schema types for your pages
You don’t need to apply structured data to every page on your site. The goal is to identify which pages have content that matches a schema type Google actively uses to generate rich results. Focus on the page types where schema makes the biggest difference for search appearance:
- LocalBusiness schema: Confirms your business name, address, phone number, and hours directly in your markup, which reinforces your local search presence
- FAQPage schema: Marks up question-and-answer content so Google can display the questions as expandable entries beneath your listing
- HowTo schema: Structures step-by-step content in a format Google can render visually in search results
- Product schema: Adds price, availability, and review information to product pages so shoppers see key details before clicking
Each schema type signals to Google that your page contains a specific kind of valuable content, which makes it easier for the algorithm to match your page to the right search queries and present it in the most useful format possible.
Validate and deploy your markup correctly
Writing valid structured data matters as much as writing it in the first place. Errors in your schema markup, like missing required fields or incorrect property values, prevent Google from reading it and disqualify your pages from rich result eligibility entirely. Google’s Rich Results Test checks your markup against Google’s own requirements and tells you exactly which fields are missing or broken before you publish.
After validating, deploy your schema using JSON-LD format inside a script tag in your page’s head section. Google recommends this format over inline microdata because it keeps your structured data separate from your HTML, which makes it easier to update and less likely to break when your page design changes. Once your pages are live, check Google Search Console under the Enhancements section to confirm Google has detected and processed your markup correctly.
Monitor, audit, and maintain technical health
Technical SEO isn’t a project you finish once and walk away from. Every time you publish a new page, update a plugin, or redesign a section of your site, you introduce the possibility of new crawl errors, broken redirects, or missing tags. Maintaining technical health means checking regularly, not just when something breaks. This ongoing discipline is what separates sites that hold their rankings from sites that slowly slip without understanding why.
Run regular technical audits
A quarterly technical audit gives you a consistent snapshot of your site’s health and catches issues before they compound into larger ranking problems. Crawl your entire site each time and compare the results against your previous audit. Look for increases in broken internal links, redirect chains, and pages returning server errors, because those specific issues tend to grow over time if nothing is actively managing them.
Your audit checklist should cover the same core areas every cycle:
- Crawlability: Are your important pages still accessible to Googlebot?
- Indexation: Are the right pages indexed and the right ones excluded?
- Page speed: Have any pages dropped below acceptable Core Web Vitals thresholds?
- Canonical tags: Are they still pointing to the correct URLs after any recent changes?
- Structured data: Are there new validation errors flagged since your last check?
Running through this list on a fixed schedule means you spend less time firefighting and more time making consistent improvements that build ranking strength over time.
Track performance in Google Search Console
Google Search Console is the most direct window into how Google sees your site, and it’s free. The Coverage report shows which pages Google has indexed and which ones it skipped or flagged with errors. The Core Web Vitals report shows real-world performance data from actual visitors, not just lab scores from a testing tool. Check both reports at least once a month.
The fastest way to catch a technical problem early is to review Search Console before a ranking drop forces you to.
Pay close attention to any sudden spike in excluded or errored pages, because those spikes almost always trace back to a specific change made to the site around the same time. Catching that pattern quickly lets you reverse the issue before Google reduces how often it crawls and ranks your pages. Following the Backlinko technical SEO approach means treating Search Console data as a standing agenda item, not an emergency resource you only open when something goes wrong.
Next Steps for Implementing Your Technical SEO Strategy
You now have a complete picture of what Backlinko technical SEO covers and how to apply it systematically to your own site. Start with a full crawl to identify your biggest problems, fix crawlability and indexation issues first, then work through speed, mobile, and structured data in order. That sequence keeps you focused on the changes that actually move rankings rather than wasting time on low-impact fixes.
Maintaining that progress takes consistency. Schedule a quarterly audit, review Search Console monthly, and treat technical health as an ongoing responsibility rather than a one-time task. Small issues caught early stay small.
