Frequently Asked Questions

Is technical SEO the same as on-page SEO?

No. On-page SEO is content and page signals; technical SEO is crawl/index infrastructure, site structure, and performance foundations.

What’s the first technical SEO check I should do?

Start with crawlability and indexability: robots.txt + sitemap + canonical/noindex checks on your most important pages.

Does technical SEO matter for AI search?

Yes. AI systems still rely on crawlable, well-structured pages. Clean metadata, internal linking, and structured data improve interpretation.
