In their own words
DefiniteSEO
DefiniteSEO brings WordPress SEO tools together with an online audit service for examining site health, AI-search visibility, backlinks, and content. Audits cover technical and on-page SEO, content, links, security, performance, accessibility, and DNS, with fixes prioritized. Its AI-visibility tools check whether ChatGPT and Google AI Overviews cite a site and assess pages for readiness for AI search. The WordPress plugin can apply individual or bulk fixes, schedule automated changes, and reverse changes within 30 days. It works with Classic Editor, Gutenberg, Elementor, and WooCommerce, and can import settings from Yoast or Rank Math. The AI SEO Writer can publish to WordPress or provide content for another CMS. Free options include an unlimited-sites plugin and an audit plan for one project and 50 pages per month. Paid plans are listed from $4.99/mo (annual). The audit service is not a standalone classic rank-tracking or keyword-research suite.
