In short

What is Technical SEO? The answer in one paragraph.

Roicool's technical SEO service reviews your site's crawling and indexing issues, speed, structured data, multilingual setup and templates, implements the fixes with your development team and checks site changes before they go live. AI crawlers' access to content is also in scope.

Last updated: 21 October 2026View as Markdown

Five problems we solve.

  • A large share of your pages is not indexed, or Search Console shows many errors.

  • The site is slow; Core Web Vitals scores are poor.

  • The same content appears on more than one URL; there are canonical and parameter issues.

Frequently asked questions

  1. Are technical SEO and an SEO audit the same thing?

    An SEO audit is a one-off snapshot of the current state. The technical SEO service covers fixing the findings, implementing them with the development team, monitoring for new issues and checking site changes from an SEO point of view.

    Copy link
  2. How much do Core Web Vitals affect rankings?

    Google uses Core Web Vitals as one of its page experience signals, but they do not replace the relevance of the content. Poor scores usually hurt conversion rates too, so improving them makes sense for both SEO and the business.

    Copy link
  3. Do JavaScript sites have SEO problems?

    They can. Google can process JavaScript, but having the content and links in the server HTML makes crawling more reliable. Some AI crawlers do not process JavaScript, so this also matters for GEO.

    Copy link
  4. Can technical SEO be done without a development team?

    Some fixes can be made through CMS settings; template, server and performance changes need a developer. If you have no development team, we can also take on the implementation for Webflow or custom-coded sites.

    Copy link
  5. Do you support site migrations?

    Yes. The URL inventory, the 301 redirect map, launch-day tests and monitoring afterwards are among the most critical parts of the technical SEO service.
