Similarweb report card
Fair · out of 4.0 · graded Oct 17, 2026
Best for sizing up a competitor's traffic
Similarweb estimates any website's traffic, audience and where its visitors come from, and its dearer plans add keyword research, rank tracking, audits, backlinks and AI chatbot tracking. Competitive Intelligence is $125 a month on yearly billing for one user. The SEO tools start at $333, and the numbers for other sites are estimates.
Who Similarweb is for
- Great if you want to see how much traffic a rival gets and where it comes from
- Handy when you're sizing up a market by comparing lots of websites
- Good for marketing teams that want SEO, ads and traffic data in one place
Who Similarweb is not for
- Pricey if you want SEO tools, which start on the $333 plan
- Skip it if you need exact numbers for other sites, as these are estimates
- Tight if your team is bigger than one, since more seats mean a custom package
Why Similarweb gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyGraded against the suites it's listed beside. Competitive Intelligence is $125 a month billed yearly ($199 monthly) for 1 user, with traffic data but no SEO tools. That's dearer than Semrush's SEO plan, and keyword research, rank tracking and audits start at $333.
- CFree plan and trialThe free version on similarweb.com and the free browser extension show a high-level sample of any site's traffic and keywords. Good for a quick look, not for real work. There's also a 7-day trial of the self-service plans.
- CFeaturesTraffic and engagement estimates, demographics and channel mix for any site, with SEO, AI and ad intelligence on dearer plans. Things the suites don't do, but the $125 plan has no SEO tools, and other sites' figures are estimates, not their analytics.
- CEase of useNo rating on record. Typing in a domain is simple, but the platform is big, and reading traffic estimates and channel splits takes some learning.
- BPlatforms and integrationsWeb plus a free extension for Chrome, Edge, Firefox and Opera. It connects to Looker Studio, Excel, Salesforce, HubSpot, Snowflake, Tableau and Power BI, but only on business packages with API access. No desktop or phone app.
What these grades rest on. Graded from this listing, whose facts were read from Similarweb's own pages on 17 October 2026. Its pricing page would not load when we went back to check it, so the prices are as the listing has them. Not based on using the product, and shorter than our full reviews. How we review and grade.

Keep Similarweb, or make your own?
Keep it
To replace Similarweb you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 16 of the 21 other SEO tools grade higher. It costs $1,500 a year.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- An index of the links between billions of web pages.
- Daily checks of where your pages rank in search results.
- A crawler that checks every page of a site.
- It plugs into other products, Google Looker Studio, Microsoft Excel and Salesforce among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Similarweb’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
