SEO Consultant: The Technical Foundation of Your Visibility on Google and in AI

No GEO without SEO: a page that bots cannot crawl, understand or index will never be cited. Since 2011, I've audited and fixed websites to make them fast, crawlable and well structured.

What does a technical SEO consultant do?

They check that search engines can crawl, display, understand and index every useful page on your website, then fix whatever gets in the way. This is the foundation of your Google rankings and your citations in AI answers.

Which SEO services do I offer?

  • Technical SEO audit: a full crawl with Arachnide SEO Spider, indexing, canonicals, hreflang, redirects, speed, structured data and JavaScript rendering. Deliverable: a prioritized list of fixes.
  • Safe migrations and redesigns: a 301 redirect plan, checks before and after launch, and monitoring in Search Console.
  • WordPress SEO: theme, plugins, performance, structure and structured data.
  • International SEO: websites in French, Spanish and English, hreflang and localized content.
  • Websites built with Lovable, Bolt and other AI tools: server rendering, metadata, sitemaps and redirects to finally make them visible.
  • Architecture and content: semantic topic clusters, internal linking and pillar pages.

Which websites?

Business websites, e-commerce, SaaS and multilingual websites in France and Spain.

How much does an SEO engagement cost?

Every SEO engagement is quoted individually after a 30-minute call to establish the size of the website and the scope.

Frequently asked questions about technical SEO

Do you still need SEO in the age of AI?
Yes. AI engines draw heavily on crawled and indexed pages, and Google points out that its AI features rely on the same foundations as traditional search. SEO is the entry requirement for GEO.
Which tools do you use?
My own crawler, Arachnide SEO Spider, Google Search Console, Bing Webmaster Tools, PageSpeed Insights and, for AI visibility, Vigie.
Can you work on a Lovable or Bolt website?
Yes. I build websites with these tools myself, including this one, and I know their SEO weaknesses: rendering, metadata and redirects.
