It's a split decision.
Choose SpyFu if Google Ads competitor research and lower entry price matter most: its annual Basic plan is $29/month, with one live tracking project and 10,000-row exports. Choose Semrush if you need a broader SEO and AI-visibility suite, including 500 daily tracked keywords on its $117.33/month annual-billing SEO plan. Semrush has a free tier, while SpyFu does not. These are different buys: SpyFu is the cheaper PPC specialist; Semrush covers more workflows but costs more.

02Pricing compared
SpyFu is the lower-cost option: Basic is $29/month with annual billing or $39 month to month. It includes 10,000-row search results and exports, one live tracking project, and one user. Pro + AI is $89/month annually; its monthly plan bills $59 for the first month, then $119/month. Team / Agency is $187/month annually or $249 month to month.
Semrush has a free tier with one demo project and 10 reports per day. Its SEO plan is $117.33/month annually or $139 month to month, with five monitored websites and 500 daily tracked keywords. Starter is $165.17/month annually; Pro+ is $248.17. Advanced and Enterprise pricing is custom. Annual prices are monthly rates, not upfront totals.
03Features and depth
SpyFu is built around competitor research for Google Ads and SEO. It shows competitors’ keywords and ads, plus ranking keywords and supporting content and backlinks. Its plans also include site auditing and rank tracking, but the caps matter: Basic allows one tracking project, 5,000 weekly tracked keyword rankings, 50,000 crawl pages and 1,000 AI fixes per month. Pro + AI raises those limits; Team / Agency allows unlimited tracking projects. Basic search results and exports are capped at 10,000 rows, while Pro + AI and Team / Agency include unlimited pulls.
Semrush covers more marketing workflows in one platform: keyword and backlink research, rank tracking, content optimization, technical audits, and AI visibility monitoring. Its SEO plan includes 500 daily tracked keywords and five monitored websites. Starter adds 50 daily AI prompts and MCP access; higher plans raise tracking limits and add features such as historical SEO data. The fit is narrower PPC competitor intelligence with SpyFu, broader SEO and AI-search visibility with Semrush.
04Ease of use and learning curve
The bigger difference is scope, not a documented setup advantage. SpyFu’s focus on competitor keywords, ads, and related SEO data gives teams a narrower set of core jobs to evaluate. Its AI audit and SpyFu GPT integration add workflows, but the published material does not publish onboarding times or setup requirements.
Semrush combines more work in one platform, including content, technical SEO, rank tracking, and AI visibility. That breadth may mean more areas to configure and learn, especially if you only need PPC competitor research. Semrush lists Basic Onboarding on its free tier; comparable SpyFu onboarding details are not published. We’d choose based on how many of those workflows your team will actually use.
