Scammers

I’m giving Similarweb 1 star.

The service quality is poor and the data is often inaccurate, which makes it hard to rely on for any serious decision-making. On top of that, after our annual contract ended, they kept trying to charge our card repeatedly despite clear communication that we were not continuing the cooperation. That behavior is unacceptable.

In my view, this is very close to scam-like practices.

That said, if you still decide to work with them, one thing worth noting: their pricing is highly negotiable. It’s surprisingly easy to push the cost down — even significantly (we managed to reduce it by up to 20x).

I didn't check Trustpilot before going on to this site... WRONG... my bad... I just wanted to see what it is, but before I got any idea, it started asking me a lot of questions about my company, title, size, etc., until it prompted me to give my phone number.... So easy to spot that this is the exact time they lost my trust. Good day to you Similarweb. I know you now, and obviously will never return. Option spilled.

Not far of being a scam in my opinion.

I signed up for the trial service and put a calendar reminder in to cancel the day before the trail was due to end (in case I didn't find the service helpful).

I logged on and cancelled on that day, and I never logged back on.

I was subsequently charged $350 on two occasions for consecutive months.

I tried to call SimilarWeb which is hard enough. When I managed to speak with someone I explained the situation and my point was, even if the cancellation did not process properly due to a system error, it is obvious I thought it was cancelled as I have not logged on or used the service since.

I was told they would look into it.

Then I had 2 seperate unconnected people call me. The first said it is unlikely they would refund. The second said they could see my point, they had checked I had not used the service, and that I would likely get a refund.

Then, radio silence.

This kind of behavior is known as 'rent seeking' in tech circles. The system is design to make it easy for you to sign up and very hard for you to cancel.

Not a good look for this company.

Steer clear.

The support staff are very responsive and helpful. I subscribed for the free trial and accidentally let it lapse, which cost me $399. I reached out to support and explained my error, and within a day they responded and initiated a refund.

2 years paying, then locked out with no support - terrible after-sales service

Almost 2 years as a paying customer, and this is how it ends.

I used Similarweb without issues for nearly two years. Then, out of nowhere, the device verification code stopped arriving to my email. Completely locked out of my own account.

I complained, and after a lot of effort, they finally restored my access. But with a catch: I could only use it on ONE specific computer. No flexibility at all for a paying subscriber.

Two months later, the exact same problem again. Locked out. Verification code never arrives. And this time, no response from support whatsoever. I have contacted them multiple times through different channels and they simply ignore me.

So here I am: a loyal customer of almost 2 years, locked out of my account, unable to cancel my subscription through the platform, and completely ignored by their support team. They keep charging my card while making it impossible for me to use the service or cancel it.

It is truly a shame that a company of this size is incapable of providing decent after-sales support. I am now forced to request cancellation via email, file a GDPR data erasure request, and escalate through my bank and consumer protection authorities in Spain.

If you are considering Similarweb, think twice. The tool itself works, but if anything goes wrong with your account, you are on your own. Check the other 1-star reviews here - my case is far from unique.

Terrible, test is not much of the product and $199 charge locked us out before we could cancel

Terrible, the test version is barely anything, and then once we were in test mode, our password stopped working consistently, and the contact us never responded until the $199 charged to our card. Nearly impossible to contact anyone to get a refund. Still working on that. STAY AWAY

WORST CUSTOMER SERVICE EVER

As an executive who has partnered with Similar web for many years, I found it very interesting that they would not let me talk to a sales associate or customer rep regarding concerns I had in the process, specifically regarding concerns of data collected, my purchase process, & more. Forcing me to talk to a BOT only, doesn't fit my desire for a company I will ever buy from again. Save yourself, avoid SimilarWeb .

[REFUNDED] Terrible experience

Most companies have it standard to send reminder emails before running the card. Especially a $420 charge. I've requested a refund after cancelling but I'm not confident I'll be getting any response. I can't imagine why they wouldn't refund customer's money that don't have a use for their service after trying it. I don't have the means to pay for this. The plan has already been cancelled the day it started. I demand my money be refunded.

Update 1/15/26: I received a full refund as of today. Ali Saribay was very professional and helpful to resolve things and forward my case along to billing. Thank you!

Hi Nikos,

Thanks for sharing your thoughts. It’s true that our traffic estimates can differ from other platforms like Cloudflare, and that’s because of how Similarweb measures digital activity. We focus on converting noisy online data into a clear signal, normalizing all digital sources into a single view. That’s why we can fairly compare sites to sites and apps to apps.

We are using a blend of data sources including:
- First-party analytics from millions of websites and apps
- Anonymous traffic data from our contributor network across millions of devices
- Publicly available information, algorithmically captured
- Partnership data from global measurement and intelligence companies

This mix allows us to provide a timely and comprehensive view of market trends and digital performance, even if the absolute numbers differ from direct server logs.

We’re here to help companies make informed decisions based on patterns, growth, and comparative insights across the digital landscape.

Best regards,
The Similarweb team

Black-listable data collection

In my book, they use Black-listable tactics for collecting data before delivering any value. Same services can be bought elsewhere without these tactics.

Trial experience

I tried the 7-day trial for this marketing tool. The product itself seems pretty good, even though the trial version was quite limited in features and daily search time.

However the sales team was way too pushy...After I canceled and told them I decided not to proceed, they kept bombarding me with follow-up emails and phone calls, even after I explained my reasons. It got really frustrating!

Overall, it’s a decent product that's worth trying at least, but the aggressive sales tactics really put me off.
