SEO Checker by Sekhlo

On-page, technical and AI search checks come together in SEO Checker by Sekhlo. It audits meta tags, headings H1 to H6 and image alt text, measures Core Web Vitals and load timings, validates SSL, sitemaps, mobile viewport and JSON-LD schema, and scores readability. Link data covers Domain Authority, Page Authority, PageRank, spam score and a backlink breakdown by nofollow, redirect and external links, with a toolbar that shows DA, DR, spam score and domain age while browsing. A GEO and AEO score targets AI search engines such as Perplexity and Gemini, and domain intelligence reports registrar, nameservers and DNS records. Optional API keys unlock DA and PA values and AI tips, stored locally, and analysis runs in the browser with no tracking.
