We have been using Similarweb for 2 years now and it is a fantastic platform for agencies and SaaS companies to understand the market they are targeting. We get insights on our prospective clients website performance and get contact details for key decision makers to begin discussions at the top of our sales funnel. The management of our account is excellent with Brett Bartholomew helping us get the most out of the tools by enabling my team through training and insights.

The site uses a dark/deceptive pattern for its onboarding/sign-up and does not allow the user access to any features or the site itself until payment information is entered. I did not enter my payment information to access the site as I cannot trust a business that uses such practices. I just wasted 5 minutes, for nothing and now need to look elsewhere for a tool that actually offers a free trial. This ain't it.

I opened an account with the intention to test the free trial. Most functionalities I was interested (e.g. backlink analysis) to test were not available in the 7 day free trial and customer service (chat) was rude/did not seem to care. I went with the competitor Ahrefs, who allowed me to test all functionalities I needed for free. When I tried to delete my account, I needed to confirm this request by clicking on a link in an e-mail they send. When I clicked on that link, I was forwarded to a page "400 bad request". I have not yet tested whether my account still works. But it added just to a poor impression about this company.

UPDATE Dec 22- I received a prompt response to this review as all can see. I did use the email provided. My inquiry was forwarded to the billing department & I received an email would be reversed. Indeed the reversed charges showed in my account within days. I am pleased & grateful with the quick response & resolution; however, I would be remiss to the community here if I did mention that no reason for the original charge was given. Since I have never none any business with this company, I still have no idea how they had access to my credit card information. dec 2 - a fraudulent charge showed up on my Visa for nearly $500. I had my Team check and we have never done business with this company before. I went online to try to find out you know from the merchant what was going on? They have offices all over the world, but not one single phone number only a web form to talk to sales. I don’t care what trust pilot says that’s a scam
