Technical SEO, explained clearly
Technical SEO refers to optimizing your website so search engines can crawl, index, and understand your content efficiently. To spot issues fast, start with a full website SEO scan. If you want to connect technical fixes to growth, pair it with keyword research and a quick review of meta tags so your best pages can earn clicks.
Then validate titles and descriptions with the Meta Tag Analyzer and check crawl rules with the Robots.txt Tester. As you build topical clusters, use the Keyword Generator to map supporting pages, and add structured data when entities or FAQs need clearer meaning.

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.
