In short

Technical health is the invisible foundation of your search rankings. You can produce the best content and earn links, but if Google does not crawl your pages or renders them poorly, it is all for nothing. We are your partners to repair those foundations.

FOR WHOM

Does this sound like you?

A technical SEO audit becomes a priority when one of these problems is slowing your growth.

01

Pages that do not rank

Your content is strong, but it stays invisible on Google.

02

Slow site

Your Core Web Vitals are in the red and the experience suffers, especially on mobile.

03

Unindexed pages

Google ignores part of your site and you do not know why.

04

JavaScript-built site

Your site runs on a modern framework and rendering is an issue.

What you get with Sitegrow

  • A complete, prioritized technical diagnosis without unnecessary jargon
  • A fast site that passes Core Web Vitals
  • Clean indexation where Google crawls what matters
  • Internal linking that distributes authority to the right pages
  • A technical base readable by Google and AI engines

What is a technical SEO audit?

A technical SEO audit is a full review of everything that determines whether an engine can crawl, render, understand and rank your site. We are not talking about content or links, but the machinery underneath. When that machinery stalls, all SEO and GEO effort suffers, often without you even realizing it.

In practice, we check how bots move through your site, how fast pages load, what is indexed or blocked, how pages link to each other, and how your code becomes a real page. Every friction point costs rankings, traffic and sales.

The stakes apply to AI as well. Engines like ChatGPT, Perplexity and Gemini rely on well-structured, fast, properly tagged sites to extract and cite information. A technically healthy site is one AI can read and recommend. At Sitegrow, we fix technical issues for Google and AI search at the same time.

Content alone will not save you anymore

Excellent content on a technically flawed site stays invisible. On top of that, with AI search, the bar is rising: content extraction, structured data and speed matter even more. Sites whose technical health is neglected lose ground on both fronts.

Here is what happens when you ignore technical health:

  • Google crawls part of your pages poorly or not at all
  • Your slow pages fall behind on mobile and lose rankings
  • Your JavaScript rendering keeps bots from seeing your content
  • AI engines struggle to extract and cite your pages

The answer is not to rebuild everything, it is to diagnose and then fix by order of impact. A healthy site is the condition for content, links and GEO to bear fruit.

Who we work with

Businesses whose SEO has plateaued despite their efforts, and those running complex sites. If your pages do not rank, if your site is slow, or if it relies on a JavaScript framework, a technical SEO audit finds the cause and fixes it.

We work especially well with:

  • Sites with many pages, where crawling and indexation become critical
  • Online stores with thousands of URLs generated by filters
  • Sites built with modern JavaScript that face rendering challenges
  • Businesses that want a healthy foundation for Google and for AI

Not sure this is for you? Book a strategy call. We review your site, run an audit, and give you a clear plan.

Our five-step approach

A technical SEO audit requires method. Here is the one we recommend, which lets you always know where your project stands.

  1. 01

    Crawling and exploration

    We crawl your site, the way Google would, to spot errors, orphan pages, redirects and wasted crawl budget. We understand what bots really see.

  2. 02

    Speed and Core Web Vitals

    We measure and improve loading, visual stability and responsiveness, especially on mobile. We target Core Web Vitals thresholds, not just a flattering score.

  3. 03

    Indexation

    We verify what is indexed, blocked or duplicated. We clean directives, canonical tags and sitemaps so Google indexes what matters and ignores the rest.

  4. 04

    Internal linking

    We structure internal links so authority flows to strategic pages and nothing important stays buried.

  5. 05

    Logs and JavaScript rendering

    We analyze log files to see how bots operate, and we resolve rendering issues so your content is visible once the page is built.

CrawlFull crawl, errors, redirectsA clear view of what bots see
SpeedCore Web Vitals, mobileA fast, stable site
IndexationCanonicals, sitemaps, directivesClean, controlled indexation

What our technical SEO audit covers

Depending on your situation, we activate the right levers. Here is what we cover.

01

Crawl and crawl budget

We identify what needlessly drains Google's crawl, such as URL parameters and low-value pages, to focus bots on important URLs.

02

Speed and Core Web Vitals

We tackle heavy images, bloated code and render-blocking resources to improve loading and experience, especially on mobile.

03

Indexation and directives

We fix canonical tags, misplaced noindex tags, sitemaps and duplicate content that confuse signals sent to Google.

04

Internal linking

We revisit link structure so key pages receive authority and click depth stays reasonable.

05

Logs and JavaScript rendering

We analyze server logs to understand real bot behavior, and we ensure JavaScript-rendered content is accessible.

FAQ

Frequently asked questions

What is a technical SEO audit and what does Sitegrow do for my business?

A technical SEO audit examines everything that determines whether Google and AI engines can crawl, render, understand and rank your site: crawl, speed, Core Web Vitals, indexation, internal linking, logs and JavaScript rendering. Sitegrow diagnoses these points, fixes them by impact, then measures gains so your content and links can finally perform.

How often should you run a technical SEO audit?

A full audit is recommended at least once a year, and before any major change such as a redesign or migration. For large sites and online stores, ongoing technical monitoring is preferable because new errors appear as updates roll out.

Does JavaScript rendering really hurt SEO?

It can. If content appears only after JavaScript runs and rendering is poorly managed, bots may never see it. We verify how your site renders for engines and fix what blocks access to your content.

Does a technical SEO audit help in AI answers?

Yes. A fast, well-structured, properly rendered and tagged site is easier for AI engines to crawl and cite. The technical fixes we deliver serve both your Google visibility and your presence in AI answers.

Want to win rather than survive?
