"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"

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.

"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.

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

Narzędzie Similarweb pozwala dostarczyć niezbędnych danych do dalszych estymacji w przypadkach, gdy nie mamy dostępu do danych z pierwszej ręki.
