Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 1 of the 21 other SEO tools we grade
Similarweb is a market and competitor research platform that estimates the traffic, engagement and marketing channels of any website. Its Web Intelligence plans add keyword research, rank tracking, site audits, backlink data and tracking of how a brand shows up in AI chatbots. Self-service plans cover one user; bigger teams buy custom packages through sales.
To get you started, here are 9 things to know about Similarweb, taken from its own pages and our grades.
Typing in a domain is simple, but the platform is big, and reading traffic estimates and channel splits takes some learning.
- 1
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.
- 2
Paid plans start at $125 a month
As its pricing page puts it: $125 per month, billed annually ($199 billed monthly).
- 3
There is a free plan
Free version on similarweb.com and a free browser extension: a high-level sample of traffic, keyword and ranking data for any site, without the deeper drill-downs.
- 4
It runs on Web
Web, with a browser extension too.
- 5
Website traffic and engagement
Estimated visits, engagement, audience demographics and marketing channel mix for any website, set side by side with competitors.
- 6
Keyword research and rank tracking
Keyword research, keyword gap analysis and a rank tracker with SERP analysis, included from the Competitive Intel & SEO & AEO plan.
- 7
Site audit and backlinks
Technical site audits and backlink data sit in the same SEO bundle, alongside an organic search overview of any domain.
- 8
A 2.0 GPA, above 1 of 21
That is against the other SEO tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
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.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Graded 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. |
| Free plan and trial | C | The 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. |
| Features | C | Traffic 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. |
| Ease of use | C | No rating on record. Typing in a domain is simple, but the platform is big, and reading traffic estimates and channel splits takes some learning. |
| Platforms and integrations | B | Web 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. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Sizing up a competitor's traffic and where it comes from
- Market researchers and analysts comparing many websites
- Marketing teams that want SEO, ads and traffic data in one place
Worth knowing
- Self-service plans cover one user and 3 or 6 months of history; extra seats and up to 37 months of history come in custom packages sold through sales.
- Keyword research, rank tracking, site audit and backlinks start with the $333 plan; the $125 plan covers traffic and competitor analysis only.
- The API, data feeds and integrations such as Looker Studio, Excel and Salesforce need a business package with API access.
- Traffic figures for other people's sites are Similarweb's estimates, not those sites' own analytics.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
