Beware! Unreliable panel data that just has gotten worse over the years. If you don’t cancel 30 days before on the dot and don’t want to renew, they’ll send you to collections even if they turn off services. Super unethical sales and support team.

I use Similarweb regularly to cross-check website traffic before making vendor or partnership decisions. It's incredibly useful for spotting sites with inflated or fake traffic numbers on other SEO tools — the real visits, bounce rate, and engagement data give a much clearer picture than search-based estimates alone. It's become a standard step in my due diligence process. Highly recommend for anyone doing vendor vetting or competitor research.
