It catches things like wrong canonical URLs, incorrect noindex settings, broken forms, missing sitemap pages, redirect chains, soft 404s, placeholder copy, externally loaded fonts, missing social images, accessibility issues, and many more.

Some checks cannot be completed from a public URL. Form notification emails, CMS settings, analytics permissions, and similar items are returned as manual checks instead of being marked as passed.

Works on any marketing site

The core review works on any marketing site, regardless of how it was built.

Platform-specific modules add extra checks for Webflow, Astro, and Next.js. review-site identifies the platform automatically and loads the right module.

Webflow reviews look for issues caused by platform settings and generated output, such as default social images, unintended collection pages, incorrect publishing settings, and staging URLs left in production metadata.

Custom-stack reviews check for things that may not have been built or properly migrated, such as SEO issues, sitemaps, redirects, 404 pages, responsive images, and font loading.
