"Best comparasion tool for marketeers"
What do you like best about Similarweb?

Similarweb is really helpful to collect growth insights. The tool is core to develop new SEM strategies and to have monthly inputs regarding competitors behavior.

What do you dislike about Similarweb?

Some paid features are really expensive, and basic needed for kickoff. The pricing should be done in an all you can eat model, to avoid lack of data in the middle of a deep analysis.

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

Similarweb is helping us to detect new keywords possibilities and also to develop content strategy based on the top performer SEO keywords for the B2B market that our company belongs.

"A Growth Marketer's Best Friend"
What do you like best about Similarweb?

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

- Tracking our competitor's performance and mix shift in ad channels/creatives/keywords/etc. (allows us to stay on top of trends in our market)

"A good help to scout new Publishers and audit their traffic"
What do you like best about Similarweb?

SimilarWeb offers comprehensive and highly informative insights on digital marketing. The custom dashboarding feature is user-friendly, making it easy to gather competitive intelligence. The level of detail provided for search keywords and display placements is impressive. The Ad Creative Research aspect is extremely beneficial for analyzing the effectiveness of display campaigns and monitoring pixel conversion. Overall, SimilarWeb serves as a one-stop-shop for competitive and digital marketing intelligence, allowing you to stay ahead of the competition by utilizing data-driven insights.

What do you dislike about Similarweb?

While SimilarWeb offers a substantial amount of data on competitive intelligence and website statistics, it could benefit from enhancing visibility for SEO, PPC, and social media metrics. Additionally, there is a two-day delay in the data feed as it relies on web crawling to gather information from the internet. Although it provides directional, high-level marketing insights, this can sometimes lead to a high margin of error when analyzing campaigns in real-time.

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

SimilarWeb assists me in tracking and comparing my competitors' search and display campaigns. The incoming visits data provides valuable insights for determining the volume of media buying. The Keywords tool is extremely useful for user acquisition on the search network, providing detailed information at the browser level. The media buying research offers a comprehensive list of suitable publishers and monetization network details for ad campaigns.

I love the ease and accessiblility of gaining insights into traffic share for competitive brand analyses! It is such a pivotal tool to our digital insights work

What do you dislike about Similarweb?

More visuals for aesthetic pleasure would be nice, but other than that I can't fault the tool! The segments for analyses are super clear but sometimes I get confused and have to re-explore the platform!

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

I can track traffic share to our clients websites but also analyse competitors to feedback insights and see search growth across a certain market and identify which websites are performing well.

Overall, I highly recommend Similarweb to anyone looking for a comprehensive and user-friendly tool to track and analyze their website's performance and to compare themselves to their competitors. Similarweb provides valuable information and data to help you achieve your online goals.

What do you dislike about Similarweb?

The universe proposed by SimilarWeb is so rich that the neophyte can quickly find himself lost in front of an impressive quantity of Dashboards and indicators without a discovery phase with a CSM Maybe the data is killing the data.

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

Similarweb is solving several key problems for its users, including: Lack of visibility into website performance: Similarweb provides a comprehensive view of website performance, including referral traffic, organic search, and paid search data, so that users can see how their website is performing and identify areas for improvement.

"Unique tool for all of search optimization (and not only) activities"
What do you like best about Similarweb?

It is suprisingly accurate. For real. We compared result of our multiple websites between SimilarWeb and Google Analytics and differences were on a fully acceptable level. If quality of all data is similar... it will be your crystal ball. You know your customers, you know your competitors. I also really enjoy intuitive export features - excel tables are well aggregated and in couple of clicks you can transform them into PPT ready graphs!

What do you dislike about Similarweb?

Interface, just a little bit. Despite modern feeling a whole UX is a bit out of date and for non-digital natives may look complicated and non intuitive. My recommendation - differentiate interface for "pro" and "regular" user. Create one view with deep dive, super detailed and advanced, and another - much more simple, for high level data.

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

Two things. First - probably most obvious and common - tracking our competitors and other e-retailers. Working in a specific industry without any benchmark, keeping website traffic and conversion as a real secret and a weapon having a chance to look (quite accurately) into competitor's results - that's amazing :) Second - keyword planning and tracking phrases popularity in Google. Ok, that's what for Google Keyword Planner was made, but I really like option of importing keyword batches, keyword suggestion mechanism and comparing keywords across websites.

"SimilarWeb Review"
What do you like best about Similarweb?

I like seeing the insights on where site visitors are located and how they are accessing the site. For example, seeing the difference between mobile and desktop traffic could make a huge difference in identifying correct value propositions based on your industry.

What do you dislike about Similarweb?

Nothing screams out as something that doesn't necessarily work well. I believe that every feature can provide value to someone based on what they do. For example, the outgoing links feature has no use for me.

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

SimilarWeb helps me identify what technologies my prospects are using, helping me come in with the correct value proposition against my competitors. Also helps to see where visitors are located to see if I can even service the prospect fully.
