A sales rep told me their product integrates with our CRM and provides company info like size, revenue, and so on. Based on that, I paid 129 for a one-month trial. I was actually charged 150 due to hidden taxes in the fine print. Once inside, I found that the features I signed up for are locked behind higher-tier plans. To even see pricing, I have to book a meeting with their sales team. Total bait-and-switch.

I've been using Similarweb for many years now and it's useful to inform our business decisions and strategy as it gives us many great competitive insights and intelligence that we won't not have otherwise.

Using similarweb for more then 5 years now. Its essential tool for me to make decisions about marketing, portfolio management etc. especially on smaller market like CEE, where is lack of information about partners. But the most important is knowledge of the customer before and during meeting with them. Knowledge is power !

[REFUNDED] I was charged $199 immediately for just 1 month use. After I canceled my 7-day trial on the first day of visiting the website, the free usage for 7 days was all gone, leaving me with a blank page. I thought I subscribed again and the 7-day trial would be refreshed, but NO, $199 was charged immediately. Now I don't even dare to cancel because I don't know if I can use it within my 1-month charged. I submitted many forms with ticket ID 1488225, 1488219, 1488218, but no response. I cannot afford this much cost. REFUND and CANCEL my subscription asap. This is too pricey I was REFUNDED after receiving Similarweb response. The experience frightened me. I don't think of visiting this website again. Anw, The Customer Service is good

Charged $240 for a subscription I never knowingly signed up for. No trial notification, no purchase confirmation email, nothing. Haven't even used the product. This feels like a scam - taking money without proper consent or communication I demand a solution for this matter Updates: an email got into the spam folder and it was in Chinese!

've been using Similarweb Pro for the past year, and it has become an absolutely essential tool in my digital marketing toolkit. While the free version is great for a quick overview, the Pro features unlock a depth of data that has fundamentally improved my strategic approach. One of the biggest wins for me has been in the area of competitive analysis. Before, I had a general idea of what our competitors were doing. Now, I can see their top traffic sources, referral sites, and the specific keywords they're ranking for that we're missing. This has allowed us to identify and target high-value keywords and uncover new backlink opportunities we wouldn't have found otherwise. For example, by analyzing a key competitor's top referring sites, we discovered a niche industry blog that was driving a significant amount of their traffic. We were able to build a relationship with that blog and get a featured post, which has resulted in a steady stream of qualified leads. Another area where Similarweb shines is in content strategy. Being able to see the top-performing pages and content for any website in our industry is a goldmine of information. It helps us identify trending topics and content formats that resonate with our target audience. We've used this data to create more effective blog posts, infographics, and lead magnets that have significantly boosted our organic traffic and engagement. For anyone on the fence about Similarweb Pro, I'd say the investment is well worth it if you're serious about data-driven marketing. The ability to get such a granular view of the competitive landscape and your own site's performance is a game-changer. It's more than just a tool; it's a constant source of actionable insights that has paid for itself many times over in our improved marketing ROI.

I signed up for a free trial in English. Every part of the process—from onboarding to the dashboard—was in English. They then billed me on day 6 - before the trial was over. But the only notification warning me of the impending charge? Sent entirely in French. I don’t speak French. I never selected French. And I never had a fair chance to cancel. This isn’t just lazy—it’s predatory. They knew exactly what they were doing. Burying a key communication in another language is a clever loophole to get one more subscription over the line. But clever doesn’t make it ethical. Or legal. No refund. No accountability. Just silence. Still waiting on a response! If this is how Similarweb operates—relying on obfuscation and dark patterns—I’d think twice before trusting them with your data, your business, or your wallet.
