SEO Layers is an SEO audit extension that runs inside the Chrome browser, positioned as a βforensic SEO audit tool.β It brings the audit panel directly into the browser, so when users visit any page, they can inspect signals such as meta tags, heading structure, links, images, Core Web Vitals, social previews, and structured data. The site states that it has 1,000+ active users, tracks 50+ SEO signals, and emphasizes 100% client-side privacy.
In terms of feature coverage, SEO Layers is more of a page-level technical SEO toolkit than a keyword ranking or backlink database product. It supports real-time robots.txt viewing, sitemap hierarchy discovery, SSL and infrastructure health checks; image audits for alt text, formats, and lazy loading; detection of internal/external links, nofollow attributes, and 404/500 errors. It also includes Core Web Vitals, performance opportunities, accessibility checks, Schema detection and JSON-LD generation, Cookie/privacy inspection, tech stack detection, GA/GTM/Pixel tag detection, and a UTM Builder. Its strength lies in presenting these signals within the context of the current page, making it useful for quickly identifying issues after launch.
The page clearly states βStart free. Upgrade when you need more.β and offers a free Chrome Extension. Several modules are marked Free, while Schema Builder, Cookie & Privacy Inspector, Tracking Builder, and others are shown as Premium or PRO ACTIVE. However, the crawled text does not disclose specific plan pricing, seat limits, payment methods, or refund policies. On the platform side, only the Chrome Extension can be confirmed; there is no visible information about Firefox, Edge, Safari, desktop clients, APIs, or enterprise integrations.
The advantages are its low barrier to entry, with a claimed setup time of under 60 seconds; broad coverage across technical SEO, performance, accessibility, marketing tracking, and page collaboration; and client-side processing, which is beneficial for privacy. The drawbacks are the lack of traditional SEO suite capabilities such as site-wide crawling at scale, keyword databases, rank tracking, and backlink analysis; limited pricing transparency; and support information that appears to be limited to Support/Articles, with no clear service-level details.
SEO Layers is suitable for independent SEOs, content operators, digital marketers, and frontend/growth teams doing single-page audits, competitor page breakdowns, tag verification, and pre-launch checks. The crawled text does not provide information on accessibility from China. Chrome extension installation and features related to Google Analytics/Meta Ads may be affected by external services in mainland Chinaβs network environment, so real-world usability should be verified with local testing. If you need site-level crawling or data-driven SEO, alternatives to compare include Screaming Frog, Sitebulb, Ahrefs, Semrush, and SEOquake.
