Check Page SEO Review 2026

Check Page SEO is a Chrome extension that audits the page in your current tab across more than a hundred on-page and technical signals — metadata length and keyword alignment, heading hierarchy, keyword density with live warnings, links, image alt text, schema and canonicalization. What pushes it beyond a basic checker is the workflow around the audit: a side-by-side competitor comparison for content-gap analysis, a Google Business Profile extractor for local SEO work, a Google Search Console integration that surfaces clicks, impressions, CTR and position inside the audit itself, and an AI prompt generator that turns findings into ready-to-paste content-rewrite prompts. Reports export as branded PDF or CSV, aimed squarely at freelancers and agencies producing client deliverables. The pricing model is unusual and genuinely favorable to light users: the free tier includes unlimited page scans forever on the core features — structural audits, semantic keyword analysis, competitor comparison, local SEO extraction — with no daily caps and no credit card. New users get a 30-day trial of the premium layer (AI prompts, schema audits, custom PDF branding, advanced report types), after which those features consume credits bought as one-time packs rather than a subscription: 1,000 credits around $15, 2,500 around $30, 5,000 around $50, with frequent discounts. The honest caveats: the product is very new, with almost no public install base or reviews yet, so reliability and support are unproven in the market. And the credit system lacks a published consumption table, so it is hard to know in advance how many audits a pack actually buys. Neither undermines the free tier, which costs nothing and has no cap — a reasonable way to evaluate whether the deeper feature set fits your client workflow before putting money in.
