Each one is here because it is genuinely the right buy for some job. The last line of each card says which.
Ahrefs
An SEO suite built on its own crawler: backlink index, site audit, rank tracking and keyword research.
Pricing. Starter $29/month; Lite $129; Standard $249; Advanced $449; Enterprise $1,499 on an annual commitment. Extra users $40–$80/month. Brand Radar AI, which tracks AI prompts, starts at $199/month.
For agents. API and MCP access included on the paid plans.
Consider it instead when: You need a backlink index and a site auditor — nobody on this page has one except the suites.
