Semrush

Semrush is a long-established platform for search marketing: keyword research, rank tracking, site audits, backlink analysis and competitor research. More recently it has added AI search features that report how often a brand is mentioned or cited in answers from AI assistants, and that track a set of prompts over time much like keywords. An MCP connection and a developer API let you pull its data into other tools.

It is aimed at SEO specialists, content marketers and agencies who need detailed search data across several sites. The breadth of the toolkit makes it more than a casual site owner usually needs, and the learning curve reflects that.

A free account gives a demo project and a small number of reports per day. Paid plans start at $139 a month for the SEO plan, with higher tiers adding more sites, tracked keywords, AI prompt tracking and historical data; annual billing lowers the price. A seven-day trial is available on several plans, and extra users and some reports are sold as add-ons.
