The verdict

Every experienced SEO uses Google Keyword Planner, not as their primary tool, but as a cross-check. When Semrush shows a keyword with 5,000 monthly searches and GKP shows it in the 1K-10K range, you're at least in the right ballpark. But building an SEO strategy solely on GKP data is limiting. The bucketed volumes, the ad-focused competition metrics, and the lack of organic SERP data all constrain what you can learn. Semrush's Keyword Magic Tool gives you the specificity and competitive context that GKP can't match.

Frequently asked questions

Is GKP data good for finding SEO keywords?
Good for broad direction. For specific targeting, the bucketed volume ranges (1K-10K) are too imprecise to make confident content investment decisions.
Which is cheaper, Semrush or Google Keyword Planner?
Semrush starts from £113.40/mo and Google Keyword Planner starts no published price, as published on each vendor's pricing page. The two vendors publish prices in different currencies, so convert at your own rate before comparing.
What do Semrush and Google Keyword Planner cost for 5 sites, 500 tracked keywords?
Semrush's cheapest plan that covers it is SEO, at £1,140.84 for the first year on yearly billing. Google Keyword Planner does not publish the limits needed to say.
Do Semrush and Google Keyword Planner have a free trial?
Semrush offers a 7-day free trial that needs a card. Google Keyword Planner's pricing page did not show a free trial or free plan.
Is there a Semrush or Google Keyword Planner Black Friday deal in 2026?
As of 31 October 2026: Semrush has not announced a Black Friday offer yet. Google Keyword Planner is not tracked on this site's Black Friday page.
