Similarweb Review: How to Make Money as an Affiliate

Disclosure: some links in this post are affiliate links. If you buy through them, I may earn a commission at no extra cost to you.

What Is Similarweb?

Similarweb is a digital data platform that shows you how much traffic a website or app gets, where that traffic comes from, and how it compares to everyone else in the market.

Think of it as a window into your competitors' numbers. You can't log into their analytics. But you can look them up on Similarweb and get a pretty good picture of what's working for them.

According to its own site, Similarweb tracks data on 100M+ websites and 4M+ apps, with years of history behind it. It's a serious tool used by marketers, sales teams, researchers, and investors.

Here's the simple version of what you get:

• Website traffic estimates for almost any domain
• Traffic sources: search, social, referrals, direct, and paid
• Top keywords and referring domains for a site
• Competitor and market benchmarking
• App intelligence, sales intelligence, and retail data
• Tracking for how brands show up in AI search tools
• Free tools, including a website traffic checker and a browser extension

For affiliates, the traffic data is the part that matters most. More on that in a minute.

How Does Similarweb Work?

Similarweb pulls together data from lots of sources and models it into traffic estimates. You type in a domain, and it shows you visits, engagement, traffic channels, top keywords, and how that site stacks up against its competitors.

The numbers are estimates, not exact counts. That's true for every tool in this space. Use them to spot trends and compare sites, not to read someone's exact visitor count.

For Users

1. Start with the free Similarweb website traffic checker (a few searches per day).
2. Enter a competitor's domain and look at traffic, sources, and top keywords.
3. Compare several competitors side by side.
4. If you need deeper data, start a free trial of a paid plan.
5. Use what you learn to pick keywords, channels, and content ideas.

For Affiliates

1. Apply to Similarweb's partner program from its "Partner with Similarweb" page.
2. Wait for the partnership team to review your application.
3. Once approved, grab your referral link.
4. Recommend Similarweb in helpful content: reviews, comparisons, and tutorials.
5. Earn a share of revenue on the clients you refer.

Simple steps. The real work is creating content people actually find.

Similarweb Pricing

Similarweb doesn't publish a simple price list for every plan. What it does show is a starting point, and the rest is quoted by sales.

There's a free trial, but the site doesn't say how long it lasts. Entrepreneur plans can be cancelled inside the platform. Business plans follow the terms in your contract.

So is it cheap? No. Similarweb is a premium tool. But you can get a lot done with the free checker before you ever pay.

Always check Similarweb's pricing page for current numbers. Plans change.

Who Should Use Similarweb?

Users

Similarweb is a great fit if you:

• Want to know how much traffic your competitors get
• Need to see which channels drive a site's traffic, not just its keywords
• Research markets before you build a site or launch a product

• Work in sales and want to find and qualify leads

• Already review tools like Semrush or Ahrefs and want a natural next recommendation

Pros and Cons of Similarweb

Pros

• Some of the broadest website traffic data around
• Shows the full channel mix: search, social, referral, direct, and paid
• Useful free tools and a browser extension
• Covers apps, retail, and AI search, not just websites
• Trusted brand used by large companies

Cons

• Expensive once you move past the free tools
• Most plans and prices are custom-quoted, so it's hard to compare
• Traffic numbers are estimates, and small sites can be less accurate
• Less focused on day-to-day SEO tasks like rank tracking and site audits than tools like Semrush

Similarweb vs Alternatives

Want the deeper breakdowns? Read my Semrush review, my Ahrefs review, and my SpyFu review. If you're on a tighter budget, my Ubersuggest review is worth a look too.

Here's the short answer. If you want to know where a competitor's traffic comes from, Similarweb is the tool. If you want to rank pages day to day, an SEO suite will do more for you.

How to Make Money with Similarweb as an Affiliate

Similarweb runs a partner program through PartnerStack. The partner page says channel partners "earn revenue share from every client referral," and it also lists an affiliate partnership option.

What it doesn't say is the commission rate, the cookie length, or the payout schedule. Those details show up after you apply. So check their site and read the terms in your partner dashboard before you build a plan around it.

Now, how do you actually earn? Three simple angles.

1. Review and Compare

People searching "Similarweb review" or "Similarweb vs Semrush" are already close to a decision. Those are the readers who click and sign up.

Write honest reviews and comparisons. Show real screenshots. Tell people who it's for, and who it isn't for.

2. Teach Competitor Research

Most beginners don't know you can look up a competitor's traffic. Show them how.

A tutorial like "how to check any website's traffic" naturally leads to the free Similarweb checker. Free tools are easy to recommend, and some of those users upgrade later.

3. Target Agencies and Marketers

Agencies use traffic data in pitches and client reports. If your audience includes agency owners, pair Similarweb with reporting tools like AgencyAnalytics. And if you write about data and scraping, my Bright Data review fits the same reader.
