Keyword.com

Keyword.com undercuts almost everything else in this category on price. The Search Visibility plan starts at $6 a month for 100 keywords, with unlimited domains and unlimited users on every tier. Most trackers cap how many sites or seats you get at the entry price; Keyword.com doesn't, which makes it genuinely usable for an agency running rank tracking across a lot of small client sites without paying a per-domain premium.

Search Visibility covers classic Google SERP tracking only. AI Visibility, priced separately, tracks how a brand shows up in AI search answers, with citation analysis and sentiment on how AI engines describe you.

360° Visibility combines both plus competitor benchmarking and prompt research. If you're looking for AI-search tracking, that is included on the AI Visibility or 360° plans instead.

A rank tracker API and an actual MCP server are included from the cheapest plan, letting an AI agent query rank data directly rather than going through a dashboard.

The tradeoff of the three-plan-line structure is that AI Visibility is metered in credits rather than a flat keyword count, so estimating your real monthly cost takes a bit more math than a straight per-keyword price. And because classic and AI tracking are sold as genuinely separate products, combining full coverage of both usually means opting for 360° Visibility rather than staying on the cheap entry tier.
