SpyFu
Competitor intelligence platform specializing in PPC and SEO competitor analysis. Download competitors' every keyword and see every place they've shown up on Google with historical data.
The problem it solves: Which keywords and ads does a competitor buy on Google? SpyFu exposes every keyword they've bid on and every ad variation, going back years.
Our verdict: SpyFu instead of SimilarWeb?
Switch if: PPC managers and small agencies whose main question is 'what Google Ads keywords and ad copy has my competitor run, and for how long' — SpyFu's ad history archive at ~$39/mo is a fraction of SimilarWeb's cost.
Don’t switch if: Anyone researching traffic beyond Google search — SpyFu has no direct/social/referral/email traffic data, no display or social ad intelligence, no app data, and its coverage is weakest outside the US and UK.
Biggest caveat: Recurring Trustpilot billing complaints: users report the advertised ~$33/mo price being charged as a lump $399 annual fee at cancellation time, and continued charges for months after cancelling.

What Real Users Complain About
Negative feedback found on public platforms — because every tool has trade-offs, and vendors won't show you these.
“They tell you $33 per month and then when you go to cancel will see they charged your card $399.”
“They continued to charge me like for eight months after canceling and then only credited back one month.”
