Semrush is in Beta. It works end to end, but it cannot read your remaining unit balance. Expect the integration to change.

​
What it adds

Each tracked question has a head keyword: the search keyword at its core. With Semrush connected, Bluemoon looks that keyword up in the question’s market and shows, on the Prompts page:
  • the Google search volume per month, with its three-month trend;
  • on hover, the keyword difficulty (0–100) and Semrush’s intent labels;
  • in the theme filter, the sum per theme with its base (“8.1k searches/mo on 6 of 12” means six of the theme’s twelve questions carry a number);
  • on the prompt detail page, a fourth stat: Google searches per month.
Most questions get a number. A question whose head keyword Semrush does not know as a Google keyword shows a dash.
This is the Google volume of the keyword behind the question, as Semrush reports it. It is not how often people ask the question to ChatGPT or another AI, and Bluemoon does not show a figure for that.

​
Connect

  1. In Semrush, open My profile → API keys and create a version 4 key. Any Semrush plan with MCP access works, which is every current plan.
  2. In Bluemoon, open Settings → Integrations → Semrush and paste the key. A workspace Admin does this.
  3. Bluemoon checks the key with one real call (10 of your Semrush MCP units) before saving it. If Semrush refuses the key, it is not stored.
  4. Click Refresh now, or wait for the nightly refresh.
The key is stored encrypted, never shown again, and never sent anywhere but Semrush.

​
What it costs you

The lookups run on your Semrush key and spend your Semrush units.
  • Each keyword costs 10 Semrush MCP API units per lookup. A workspace with 150 distinct keywords across its markets spends about 1 500 units a refresh.
  • Each keyword is refreshed every 28 days. Semrush’s terms allow holding its data for one month, so a number older than a month is no longer shown, and is deleted shortly after.
  • A keyword Semrush does not know is not looked up again for 28 days.
  • Your key is used only for your workspace’s keywords, and the numbers it returns are not shared with other workspaces.
Semrush MCP units are a monthly allowance of your Semrush plan. When they run out, the refresh stops for the month and the Integrations row reads needs attention: “Your Semrush account has no MCP API units left this month.” Numbers already collected stay until they are a month old. You can see your balance in Semrush under Subscription info; Bluemoon cannot read it.

Disconnect

Disconnect deletes the stored key and every number it bought. The column disappears from the Prompts page.
