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.
Siteliner
Siteliner is a web and API service that crawls a website for quality issues, including internal duplicate content and broken links. Its duplicate-content check highlights matching material on pages while excluding common elements such as menus and navigation. The service flags broken internal links and identifies pages prominent to search engines from link patterns across the site. Reports include site and page results, a standard XML sitemap, and CSV downloads for the site report and currently displayed table. The Premium API can start scans and return results in JSON, with PHP and Python sample code. Starting an API scan costs 1c per page scanned, and each result request costs 1c. Siteliner requests four pages at a time. It reads publicly accessible pages unless non-logged-in requests from its servers are allowed. Summary reports remain available for 185 days; highlighted links, duplicate content, and cached pages remain for 60 days. The free plan covers 250 pages once every 30 days.
