On-Page SEO Checker & AI Visibility — BEsERP

Check any page's SEO in one click — titles, headings, links, alt text, and whether AI crawlers can actually read it.

Check the SEO of any page in one click — and find out whether AI assistants can actually read it. WHAT IT CHECKS Indexing — noindex directives, canonical targets, and whether the page declares its language. Content — title length, meta description length, and whether there is enough content to rank. Structure — H1 count, heading hierarchy (including skipped levels), internal link count, and generic anchor text like "click here". Media — images missing alt text, and images missing width and height attributes that cause layout shift. Sharing — whether Open Graph tags are complete, so shared links do not render as a blank card. AI visibility — how much of your text exists in the HTML before JavaScript runs, and whether the page has valid structured data. WHY THE AI CHECK MATTERS Most AI crawlers do not execute JavaScript. A page whose content only appears after hydration can rank perfectly well in Google and still be completely invisible to ChatGPT, Perplexity and Claude. This extension re-reads the page the way a crawler sees it and tells you how much survives — a check no other SEO extension performs. EVERY FINDING COMES WITH THE FIX Not a list of complaints. Each issue explains what is wrong, why it matters, and what to change. Findings are ordered worst-first, so the thing that actually needs attention is the first thing you see. PRIVACY Nothing leaves your browser. The analysis runs on your own device, there is no account, no sign-in, no analytics and no tracking. We never see the pages you check. The extension asks for two permissions — activeTab and scripting — and nothing else. It requests no host permissions and registers no content scripts, which is why Chrome does not warn you that it can read your data on all websites. It cannot. The analysis script is placed into one tab when you press the button and is gone afterwards. FREE, AND STAYING FREE This is free because it costs us nothing to run. Everything it does is computed from the page your browser has already loaded — no servers, no API calls, no AI models on our side. There is no trial, no credit card and no usage limit.
