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.
Keyword Tool
Keyword Tool generates long-tail keyword suggestions from autocomplete when given a seed term. It supports keyword and competitor research across 16 platforms, including Google, YouTube, Bing, Amazon, TikTok, Reddit, Pinterest and Google Trends. The free tool works without an account and can return 750+ Google autocomplete keywords. Paid plans add search volume, cost per click, competition scores, device breakdown and historical trends; they also support search-volume enrichment for up to 1,000 keywords per request, with daily capacity depending on the plan. Access includes the web interface, API and MCP, and Claude, Cursor and ChatGPT are named as compatible assistants. Google coverage includes 190+ countries, 68,000+ locations and 50+ languages. The site says Google and Bing metrics come from planner ecosystems, while volumes for other platforms are modeled estimates based on clickstream signals. Web, API and MCP share a daily request pool, and available MCP tools can vary by endpoint, plan and rollout status. Paid plans start at $68 a month. There is no free trial; the pricing FAQ lists a 30-day money-back guarantee for paid plans.
