Seodar
Seodar is a technical SEO platform. It crawls a site, scores its health against 195 technical checks, and ranks the fixes by how much score each one returns for the effort involved - so teams work from a priority list rather than a dump of issues. Every finding says why it matters and what to change.
Beyond the audit it covers keyword research and rank tracking, competitor comparison scored by the same checks, backlink data, Google Search Console and Bing Webmaster integration, WCAG 2.2 accessibility checks on rendered pages, uptime and regression monitoring, URL segments and custom rules.
It also measures AI visibility: whether ChatGPT, Claude, Gemini and Perplexity know a site and cite it, and whether it appears in Google AI Overviews.
Agencies can white-label the interface and the scheduled PDF reports their clients receive. There is a REST API and a WordPress plugin. Any site can be scanned free, with no account and no card.
