"incredibly useful tool for affiliate marketing"
What do you like best about Similarweb?

- The tool is incredibly useful for affiliate marketing specialists and agencies to identify competitors on a vertical, find partnerships and optimize SEO campaigns. I appreciate the ability to add up to 4 competititors websites and track it against the client's. - Outstanding Customer support. Kate, our point of contact, is always ready to jump on a call to walk through an issue or advise on a feature. - High-quality white papers/reports. Heatmaps diagram prepared by SW for Q1, helped my agency contextualize industry trends for clients.

What do you dislike about Similarweb?

A complex tool like SW does require some time to get into. I appreciate the helpful how-tos on every page, and after a while, further navigation becomes much easier.

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

1. Affiliate recruitment. it's easy to see top contributing websites. 2. understanding of inbound and outbound traffic 3. understanding competitive space across different geos. this in turn makes my competitive analyses more detailed and relevant. 4. ad performance. knowing performance of each ad helps optimize campaigns.

"Great tool for everybody in digital world"
What do you like best about Similarweb?

The best thing about Similarweb is the ease of use of this tool. If you are a numbers person, you can get very detailed information, but if you prefer charts, the tool also gives you that option.

What do you dislike about Similarweb?

Similarweb's greatest weakness is its greatest strength, which is the complexity of the tool. You can monitor so many things that it is sometimes difficult to find what you are looking for at first.

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

"Awesome tool for Organic Performance Intelligence"
What do you like best about Similarweb?

Similarweb's tool is very useful in the daily work of Organic Performance specialists, as well as in numerous media tenders. Thanks to the large amount of data, which is very well presented in terms of UX, finding and drawing conclusions is very easy. The accuracy of the data is also very important, I have checked the GA data of clients many times and they are very close to reality. You can certainly use them for estimating for tenders, where we don't have first-hand access.

What do you dislike about Similarweb?

Eveyrthing is top-class, however some more SEO specific tools will be appriciated as we run SEO (Organic Performance) Practice mostly with my team. There is no downsides from my perspective.

"Similarweb used from a Marketing student at the number 1 university for Marketing in the UK."

Limited coverage: Similarweb may not track data for all websites, especially smaller or less popular ones. This means that its data may not be representative of the entire web.

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

Similarweb helps me a lot when I run competitors analysis as well as understanding website traffic. It helps me identify areas where my given companies are lagging behind and opportunities for improvement.

The website traffic feature is a must-have for us. Also, Similarweb has the most intuitive tool to prospect based on industry. The latest update even suggests you similar industries you might have missed out on your manual search.

What do you dislike about Similarweb?

I'd appreciate it if we could have better matches with regard to direct competitors of companies we're looking into. If you know you can cater to a specific entity, it makes sense to try and find out their direct competitors because most likely, they'll have the same needs.

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

"Valuable and Actionable Data"
What do you like best about Similarweb?

Setup was easy and I was able to start finding actionable data about my site and my competition within minutes of getting into my account.

What do you dislike about Similarweb?

When comparing my company to the competition, many reports show data at the industry level, when I would like that same report to show each company in the industry's data. You can only do so by exporting the data and creating reports in Excel or another program.

"Excellent tool. Invaluable once you learn everything that you can get from it."
What do you like best about Similarweb?

By far the most thorough data set out there for the purposes of understanding how people browse the web. As someone who works in digital marketing strategy, it is an extremely valuable resource for understanding how my clients benchmark against the industry, what their competitors are doing, researching new opportunities and providing insights that simply aren't available anywhere else. The UI is simple and reliable, there are always new features being released and the customer support we receive is very strong (with regular training sessions being offered to our agency).

What do you dislike about Similarweb?

My only complaint is that some of the media spend data is innaccurate and really shouldn't be trusted. I understand that this is extremely hard to model, and honestly think they should just remove this section as I've seen colleagues lose trust in the entire tool because of the innaccuracy of this data.

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

Understanding how our clients are performing compared to their industry, understanding industry trends overall, and getting insights and providing recommendations based on what competitors are doing (e.g. search terms they show for, distribution of channels etc.).

"Strength of the products in other markets"
What do you like best about Similarweb?

I like that the product is a complete suite of data that is more or the same as our accurate internal data. The interior features many which work for me and my team. I am particularly interested in a full-stack vp of marketing.

What do you dislike about Similarweb?

I wish there were a pre-done dashboard for comparison, especially looking at micro-segments vs. merely having a suite to mine data. I want to do competitive analysis simply by pressing a button. Having to do things manually is a bit challenging and time consuming. Being unable to analyse folders is also a challenge with SW.

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

Competitive analysis in a competitive industry gives me a reasonably accurate reflection. That's the most effective way to analyze my competitors, but it does better with a few pre-done templates for analysis without all the manual stuff.

"Similarweb allows you to gain a competitive advantage"
What do you like best about Similarweb?

Similarweb allows you to gain a competitive advantage by providing you with detailed information about your competitors' online activities, including their website traffic, search engine rankings, social media presence, and advertising campaigns. This information can be used to optimize your own online marketing strategies.

What do you dislike about Similarweb?

It can be overwhelming or difficult to use for users who are not familiar with digital market intelligence tools. Similarweb provides a wide range of features and data points, which can be overwhelming for users who are new to the platform or who do not have a strong background in online marketing or analytics.

There are not many digital tools for tracking, especially in the field of search (keywords). Everyone can easily find out how the brand performs among competitors.

I'm waiting for further development, mainly apps and SMART TV as a part of the universe. As a consequence, currently, Similarweb covers only a part of the market. I'm working for video industry so every screen is very relevant.

"The tool we need to shorten the competitor gap and reduce the learning curve."

Hands down competitor analysis. It's worth the price to have a clear picture of what your competitors and your industry are doing. Keeps us informed on what trends are emerging and how to stay ahead of the curve.

We use both SEMRush and Similarweb. We have fully transferred our workflow to Similarweb. The hands on training has been great but we still need to find time to make the full transition.
