"Limited use for PR teams"
What do you like best about Similarweb?

Outside of insight on visitors, there isn't much information for PR teams to use to add their outreach/campaigns.

Provides more up to date numbers than other platforms.

"Great product, but just not for us"
What do you like best about Similarweb?

SimilarWeb provides a comprehensive view of web traffic between my company and competitors. The platform is easy to navigate and use with lots of valuable insights.

What do you dislike about Similarweb?

The only drawback is the data quality. I understand SimilarWeb's data is based on sample data + their proprietary algorithm, so sometimes the data does not match with our internal data very well.

What problems is Similarweb solving and how is that benefiting you?

Competitor website traffic and relevant information. A great tool for competitive intelligence research and to better understanding where my company stands in the game given we heavily rely on digital channel.

"The information is useful, but sometimes I struggle with figuring out how to navigate the site."
What do you like best about Similarweb?

I like seeing traffic, volume, and month over month change. It'ls also helpful to see by industry what are top search terms.

What do you dislike about Similarweb?

However, 1) I wish the default would be the US instead of Canada, 2) I wish I could see day by day change to know if a term spikes on a certain day of the week.

What problems is Similarweb solving and how is that benefiting you?

Helping me see from a consumer journey lens what consumers are searching for when they're thinking of certain industries.

"Simple beginner analytics tool that is easy to pick up and get started on"
What do you like best about Similarweb?

The modules are easy to set up. The interface is easy to get around and there is little barrier to quickly set up a simple dashboard for high level overview monitoring.

What do you dislike about Similarweb?

The dashboards cannot be shared with their full interactive functionality to other people without them having a seat on my account. I want to be able to let others see the full data and data points (not necessarily make changes)

What problems is Similarweb solving and how is that benefiting you?

Viewing site traffic without a full Google Analytics or Adobe Analytics setup. I can view quick high level data right away without having to do a whole complex set up first.

"Most of the details are over rated but it's good for initial research"
What do you like best about Similarweb?

You can get a bit idea about how great a website is. Also, you can decide your potential competitors with it.

What do you dislike about Similarweb?

Most of the data is overrated. Where the actual monthly traffic will be 15K, this platform shows more than 1 lakh per month. So you actually can't rely every time on this. Also, their support system is very poor and the guys are full of attitude. The way they greet the customers is pathetic. The worst part is you have to wait for 2 months to get your things done.

"Too basic for someone focused on running a website"
What do you like best about Similarweb?

Similarweb presents information in a very clear and easy-to-understand manner, which is especially helpful for beginners entering the online/website space. Their intro page on a website in particular gives a good overview of the business

What do you dislike about Similarweb?

For many use cases, the functionality that Similarweb provides is just too limited compared to what is available from competing analysis tools that I have used (specifically SEMRush and Ahrefs), and Similarweb is actually even more expensive than the competing tools in my experience

What problems is Similarweb solving and how is that benefiting you?

I previously used Similarweb in order to analyze my website performance and look for opportunities for growth. My hope was to look for keyword and backlink opportunities for the site, analyze competitors, and make technical SEO improvements to my website. I found the Similarweb functionality to be too limited to be able to do these things effectively, and now use both SEMRush and Ahrefs for this analysis instead.

"BROKEN & NOT FIXED"
What do you like best about Similarweb?

When Similar Web was working, the extension could give you a good idea on a website's web traffic. Both US only and international. It gave so much useful data to help me decide if a company is worth reaching out to.

What do you dislike about Similarweb?

The extension does not work and when you plug in a url on the website, it gives 2 points of data, nothing compared to what it did before.

What problems is Similarweb solving and how is that benefiting you?

After seeing the web traffic, it helps me estimate how many orders they are getting a month. This allows me to decide if they are in our wheel-house and worth reaching out to.

"Similarweb Equals Poor Support, Frustrating User Experience, and Only an Adequate Data Source"
What do you like best about Similarweb?

Similarweb has robust reporting and data availability, but it is very expensive given that almost all of the data points seem to be available through other platforms like Google Search Console, Google Analytics, SEMrush, and etc.

What do you dislike about Similarweb?

I experienced a six-week delay in being able to simply log in to my existing subscription due to passive, ham-handed support, ongoing systems issues with the Similarweb platform that made my login impossible, and unnecessary delays. In the end, I was the one that figured out a workaround that ended my six weeks of frustration, and then Similarweb outright refused to extend my subscription by any amount as a goodwill gesture for the lost six weeks I had already paid for.

What problems is Similarweb solving and how is that benefiting you?

I requested that their support team set up a session with me that would clarify the data points available in Similarweb that are unique to the platform. However, that training won't happen now that I'm refusing to renew my subscription due to their poor customer service.

"Support does not respond. Can't access half the data on a Trial after giving credit card"
What do you like best about Similarweb?

I'm not sure. Because I'm not even sure the data is very accurate.

What do you dislike about Similarweb?

I have attempted to contact support multiple times to try and get a fair trial to see data. It's been nothing but crickets for about four days. They are very keen on setting up a 1 to 1 chat with you on an automated calendar but not letting you try the software even after taking your credit card for absurdly high subscription fees.

"Scam Inaccurate Data"
What do you like best about Similarweb?

They are only nice while selling to you afterwards they are loan sharks behaviour.

What do you dislike about Similarweb?

We tried their service for a lead generation we paid over 10800 dollars for a quarter and it was completely inaccurate data every time we tried to talk to customers about their web performance their numbers were incredibly off. We did not ask for a refund although we used it for about 2 weeks and they did not even try to understand what went wrong and maybe remedy or offer a solution they went to Debt Collectors for the 1-year contract. Absolutely disgusting behaviour from a company that is listed nevertheless. I do not recommend it at all. Scam service with inaccurate data and ridiculous business practices.

What problems is Similarweb solving and how is that benefiting you?

They have complete inaccurate data.

"SW has very inaccurate data or no data at all for many regions"
What do you like best about Similarweb?

Easy User Interface and supposedly promised good features, that in reality wasn't refelcted in terms of data availability or accuracy.

What do you dislike about Similarweb?

Once subscribed, most of the regions we subscribed to had no data or the data we got was laughed at by clients as the discrepancies were unrealistically high. Such a high price and still couldn't get the job done that I was using the free version of other solutions that were even moore helpful. Waited for weeks for a solution or response from the account management and got no response nor our problem was solved.

What problems is Similarweb solving and how is that benefiting you?

We were trying to understand potential clients' traffic and competitive landscape.

"Don't pay for premium"
What do you like best about Similarweb?

The free extension and our CSM is definitely trying to make us happy.

What do you dislike about Similarweb?

This is not a technology, but a service. You enter domains in a spreadsheet that can do look-ups. You cannot easily do a list build and the way they do look-ups eats into your API calls, which are limited every month. My CSM is definitely trying to be helpful, but the technology is just not there. If you are in the US, they are based in Israel, so you will usually get a response the following day. So far, I am disappointed that I moved from free to premium.
