How much keyword research does each Semrush plan let you do in a day?
Summary
Starter allows 3,000 Keyword Magic Tool reports a day with up to 10,000 rows each, Pro+ allows 5,000 reports and 30,000 rows, and Advanced 10,000 reports and 50,000 rows. Separate from those daily caps, Keyword Strategy Builder allows only 10 clustering runs a month on Starter, and every account can store 200,000 keywords in total, a ceiling that never resets. For teams that plan a lot of content, those two numbers decide the plan.
How the plans map to the help center's limits
Semrush's help pages still publish keyword limits under the SEO Toolkit tier names Pro, Guru, and Business. The Site Audit article spells out the mapping: Starter includes Pro, Pro+ includes Guru, and Advanced includes Business. The $139 SEO plan is described on the pricing page as "basic keyword research and competitor analysis," and no help page says which tier it matches.
Per tier, Pro / Guru / Business:
- Keyword Magic Tool reports per day: 3,000 / 5,000 / 10,000
- Rows per report: 10,000 / 30,000 / 50,000
- Seed keywords per hour: 100 on all three
- Keyword metric refreshes per month: 250 / 1,000 / 5,000
- Keyword Strategy Builder clustering runs per month: 10 / 30 / 50
A free account gets 10 reports a day, sees 10 rows in the interface, and cannot export.
The monthly clustering cap
Keyword Strategy Builder takes up to 10,000 keywords and sorts them into topics, pillar pages, and subpages. You can start from up to five seed keywords or upload up to 2,000 of your own at a time. The help center counts clustering and structuring as monthly "actions," and Starter gets 10.
Picture a content team that plans 12 new topic clusters every month. Starter's 10 runs leave them two short. Pro+ gives 30 runs for $299 a month, which is $100 more than Starter.
Storage that deleting does not free up
Every plan can hold 200,000 keywords in total across all Keyword Strategy Builder lists. The help center says this capacity does not reset monthly and that "deleting lists does not restore this capacity." Two 10,000-keyword lists a month fill it in ten months, and test lists you throw away still count against it.
Prompt Research runs on a different allowance
Prompt Research, which draws on a database of prompts captured from real AI requests, sits in the AI Visibility Toolkit, not the SEO Toolkit. It is available on Semrush One plans (Starter and up) or with the standalone AI Visibility Toolkit, which allows 1,000 Prompt Research queries a day. The SEO plan does not include it.
