§ 02 / the problem

On-page SEO was scattered across ten different tabs.

Checking whether a page was actually ready to ship meant bouncing between a meta-tag previewer, a link checker, an image-alt scanner, a sitemap validator, a schema inspector, and whatever else a marketer remembered to look at. Half the tools gated the useful bits behind a signup, and the other half only checked one thing.

§ 03 / our approach

One URL in, one full report out.

SEOtest.app runs eighteen on-page checks in a single pass — meta tags, heading structure, internal and external links, image alt text, sitemaps, robots.txt, social previews, schema markup, HTTP headers, page speed, mobile viewport — and returns a consolidated report with no signup. A companion Chromium extension puts the same checks one click away while browsing. Free, honest defaults, no upsell wall.
