Technical SEO
A fast, secure, crawlable foundation so nothing technical is quietly holding your rankings, or your AI visibility, back.
What Is Technical SEO?
Technical SEO is the infrastructure layer underneath everything else: whether your site loads fast, whether search engines can actually crawl and index it, whether it's secure, and whether the code itself is clean enough for a search engine, or an AI engine, to trust. A trade business can have excellent content and a strong Google Business Profile and still underperform if this foundation is broken, because technical SEO doesn't win rankings on its own, it decides whether everything else you do even gets the chance to.
It matters more now than it used to, not less. Most AI crawlers, including the ones behind ChatGPT and Perplexity, fetch a page's raw HTML but don't execute JavaScript the way a browser does. If your content or your schema only exists after a script runs, it's invisible to a growing share of how people actually search now. We build the technical foundation to work for Google and for the AI layer sitting on top of it, not one or the other.
How We Actually Build A Technically Sound Site
Every site gets checked and built against all of these, since a technical gap in one area quietly caps whatever's working everywhere else.
Crawlability & Indexability
If a page can't be reliably found and understood by a crawler, it can't rank and it can't be used in an AI-generated answer either, no matter how good the content is.
Sitemap & Robots.txt Configured Correctly
An accurate XML sitemap submitted to Search Console, and a robots.txt file that blocks what should genuinely stay private without accidentally blocking pages that should be ranking.
Clean Architecture, Everything Within A Few Clicks
A logical site structure where every important page is reachable within a few clicks of the homepage, since a page buried too deep gets crawled less often and trusted less by search engines.
No Orphaned Or Accidentally Blocked Pages
Every page that should be indexed actually gets linked to from somewhere else on the site, and none of them are quietly excluded by a leftover noindex tag or a misconfigured rule.
Core Web Vitals & Page Speed
Core Web Vitals are a direct Google ranking factor, and a site that fails them is conceding a real advantage to a competitor whose site passes.
Largest Contentful Paint, Optimized
How fast the main content of a page actually finishes loading, kept under Google's threshold instead of being left to whatever the default theme happens to deliver.
Interaction To Next Paint, Not Just Load Time
How fast the page actually responds once a visitor taps or clicks something. This is the Core Web Vital most sites fail in 2026, and it depends on how much JavaScript is running in the background, not just how fast the page first appears.
Compressed Assets & Caching
Images, scripts, and fonts get compressed and cached properly so returning visitors, and repeat crawler visits, load the site faster on every pass.
Structured Data, Treated As A Deterministic Layer
Prose gets interpreted by an algorithm, but structured data is a direct, explicit statement of fact. In 2026 that distinction matters more than ever for how confidently an engine cites you.
JSON-LD, Not Older Microdata Formats
Schema written as JSON-LD, the format Google explicitly recommends and the one every major AI crawler parses most reliably, kept in a single clean block separate from the rest of the page's code.
Schema That Matches The Visible Page Exactly
Organization, LocalBusiness, FAQPage, and breadcrumb schema that mirrors what's actually visible on the page word for word, never hidden or invented data just to chase a rich result.
Built To Be Read By AI Crawlers, Not Just Googlebot
A growing share of AI crawlers can't execute JavaScript the way a browser does, so anything that only exists after a script runs is effectively invisible to them.
Server-Visible Content & Schema
Critical content and structured data exist directly in the raw HTML a crawler receives on first request, not only after client-side JavaScript finishes rendering the page.
llms.txt, Evaluated Honestly, Not Assumed
llms.txt is a proposed standard for guiding AI crawlers, but adoption still sits at roughly 10% of domains and no major AI platform has confirmed it actually changes what gets cited. We assess it for each site rather than adding it everywhere just to check a box.
HTTPS, Security & Duplicate Content
These are foundational enough that most visitors never notice them, and Google penalizes their absence anyway.
Full HTTPS Coverage, No Mixed Content
Every page served securely with no leftover HTTP resources triggering browser warnings, which is both a trust signal and a confirmed ranking factor.
Canonical Tags & Cleaned-Up Redirects
Canonical tags on every page to stop near-duplicate URLs from splitting ranking signals, and redirect chains and loops cleaned up so both crawlers and visitors reach the right page in one hop.
Core Web Vitals Thresholds We Build To
| Metric | What Google Considers Good |
|---|---|
| Largest Contentful Paint (LCP) | Under 2.5 seconds. Measures how fast the main content of the page finishes loading. |
| Interaction To Next Paint (INP) | Under 200 milliseconds. Measures how fast the page responds to a real click or tap. |
| Cumulative Layout Shift (CLS) | Under 0.1. Measures how much the page visually jumps around while it's loading. |

Frequently Asked Questions
How do I know if my site has technical SEO problems?
Most technical issues aren't visible just by looking at the site. A proper technical audit, which is part of every free audit we run, checks the things a normal visitor would never notice but that Google and AI crawlers absolutely factor in.
What's the difference between a website audit and technical SEO?
The audit is a one-time diagnostic that finds and ranks every issue by severity. Technical SEO is where those issues actually get fixed, and where the technical foundation gets maintained as the site grows and changes.
Will fixing technical SEO issues actually improve rankings on its own?
It removes a ceiling on what your other SEO work can achieve rather than creating a ranking jump by itself. Technical SEO is a qualifier, not a differentiator: it makes sure your content and off-page work actually get the chance to compete, it doesn't replace them.
Do you add llms.txt to every site?
No. It's a genuinely useful signal to evaluate, but adoption is still low and no major AI platform has confirmed it changes citation behaviour. We assess it honestly for each site instead of adding it everywhere as a default.
Do you handle technical SEO for sites not built by Visarrow?
Yes. Most of our technical SEO work happens on existing client websites, regardless of who originally built them.
