Technical SEO

Technical SEO services: crawling, rendering and indexing done right

If search engines and AI crawlers cannot reach, render and interpret your pages, nothing else you do in search will work. We find and fix the plumbing.

The problem

Common technical failures we see

  1. 01 Key content only appears after JavaScript runs, so some crawlers see an empty page.
  2. 02 Duplicate URL variants (parameters, trailing slashes, http/www) split signals and waste crawl activity.
  3. 03 robots.txt or a CDN firewall blocks crawlers you actually want — including AI search bots — without anyone noticing.
  4. 04 Site migrations ship without a redirect map, and years of earned links point at 404 pages.

Explained

What technical SEO covers

Technical SEO is the part of search optimization concerned with access and interpretation: whether crawlers can fetch your URLs, whether the content they receive is complete, whether the right version of each page is indexed, and whether pages load fast enough for real users.

Why it matters for AI search too

Many AI crawlers fetch pages without executing JavaScript the way a browser does. If your main content, headings or links only exist after client-side rendering, those systems may see far less than your visitors do. Clean HTML, sensible URLs and an explicit crawler policy are now prerequisites for visibility in AI search, not just in Google.

Crawler access, decided deliberately

Different bots do different jobs. OpenAI, for example, documents OAI-SearchBot (used to surface sites in ChatGPT search), GPTBot (used for model training) and ChatGPT-User (fetches made on behalf of a user). Google documents Google-Extended as a control token for Gemini training and grounding that does not affect Google Search inclusion. Blocking the wrong one can quietly remove you from an answer engine. We read each vendor’s current documentation and write a policy that matches your goals.

Prisol’s approach

Our Technical SEO approach

Evidence from logs and crawls

We combine crawler simulations, Search Console reports and, where available, server logs to see what bots actually request and receive.

Fix by template, not by page

Most technical issues live in templates and configuration. Fixing the template fixes thousands of URLs at once.

Write developer-ready tickets

Each recommendation includes the problem, the evidence, the expected behaviour and acceptance criteria your developers can test against.

Verify after release

We re-crawl and check Search Console after every release to confirm the fix worked and nothing regressed.

Deliverables

Technical SEO deliverables

Scope is agreed per engagement. These are the standard components.

  • Crawl & indexation audit

    Status codes, canonicals, noindex usage, sitemaps, orphan pages, redirect chains and index coverage, explained in plain language.

  • Rendering review

    Comparison of raw HTML and rendered DOM for key templates, with recommendations for server-side or static rendering where content is missing.

  • Core Web Vitals plan

    LCP, INP and CLS diagnostics on real templates using field and lab data, with prioritised fixes for images, fonts, scripts and layout.

  • Structured data implementation

    Accurate JSON-LD for organisation, articles, services, products or breadcrumbs that matches visible content and validates cleanly.

  • Crawler access policy

    A documented robots.txt and firewall policy covering Googlebot, Bingbot and AI crawlers such as OAI-SearchBot, PerplexityBot and Google-Extended, based on each vendor's published documentation.

  • Migration support

    URL inventory, redirect mapping, pre-launch checks and post-launch monitoring for platform or domain moves.

Process

Our Technical SEO process

  1. Step 1

    Discover

    Crawl the site, collect Search Console and analytics data, review templates and hosting.

  2. Step 2

    Prioritise

    Rank issues by impact on indexation and revenue-driving pages, not by tool severity scores.

  3. Step 3

    Implement

    Tickets for your developers, pair sessions, or direct implementation on supported stacks.

  4. Step 4

    Verify

    Re-crawl, monitor index coverage and Core Web Vitals, and close the loop in the report.

In practice

Technical SEO example scenarios

Illustrations of the kind of work involved — not client results.

Making JavaScript content visible

A React marketing site rendering service descriptions client-side is moved to static generation, so headings and copy are present in the initial HTML for every crawler.

A migration without lost URLs

Every indexed URL on an old WordPress site is inventoried and mapped to its closest equivalent before launch, with redirects tested in staging.

FAQ

Technical SEO FAQs

What is the difference between technical SEO and regular SEO?
Technical SEO covers the infrastructure that lets search engines access and interpret a site — crawling, rendering, indexing, speed, structured data. The rest of SEO deals with the content and authority of the pages themselves.
Should we block AI crawlers in robots.txt?
It depends on what you want. Search-oriented crawlers like OAI-SearchBot and PerplexityBot are what let your pages appear in those products' answers. Training crawlers like GPTBot, or the Google-Extended control token, are separate decisions. We document the trade-offs per crawler so you can choose deliberately.
Can you work with our framework or CMS?
Yes. We regularly review WordPress, headless CMS, React/Next-style and static-site builds. The principles are the same; the fixes differ.
Do Core Web Vitals affect rankings?
Google uses page experience signals, including Core Web Vitals, but relevance and quality matter far more. We treat speed as both a ranking consideration and a conversion improvement.
