Rankizo

Rankizo is an SEO research platform with something almost nothing else in this category has: a hosted MCP server. Connect Claude, Cursor or any MCP client to https://app.rankizo.com/api/mcp and your agent calls the same 17 tools the app uses — keyword research, domain overview, SERP results, backlink profiles, content gap, rank tracking — inside your own workspace, against your own credit balance. No API key to paste; it is an OAuth 2.1 resource server, so the client registers itself and you approve it in a browser. The other thing Rankizo does differently is pricing. Every tool quotes its exact cost on the confirmation step before it runs, computed with the same conversion that charges you — no monthly row quota you discover you have exhausted, and no per-seat licence. Invite the whole team; credits are the only meter, and unused ones roll over. What is in the box: keyword research with volume, difficulty, CPC and intent; domain overview and content gap; a backlink checker that works at the level of the individual link, with anchors and spam scores; bulk analysis of up to 100 domains at once; scheduled rank tracking on desktop and mobile, including whether an AI Overview cites you; and a technical site crawler that runs on our infrastructure and is not credit-metered at all. Lead Finder is the outlier. Every other tool in this category starts from a domain or a keyword you already have. Lead Finder starts from a technology — pick a CMS, an analytics tag or a payment processor, or paste a literal HTML snippet, and get the sites running it, filtered by country and domain rank, ready to qualify and export.
