Key takeaways
- Similarweb estimates total traffic from all channels. Most Similarweb alternatives estimate organic search traffic only. Know which one you need before you switch.
- Similarweb's Starter plan is about $149 a month. Semrush Traffic Analytics is the closest paid match. Ahrefs and Zutrix are cheaper for organic estimates.
- No tool measures a competitor's real traffic. Every number is a model. Use the same tool for every competitor so the errors cancel out.
- The free Similarweb alternative for your own site is Google Analytics plus Search Console. For a competitor, a keyword rank tracker gives you a real signal instead of an estimate.
Similarweb is the website traffic checker people open to answer one question: how much traffic does that site get? Then they see the price, or the "contact sales" button, and start searching for Similarweb alternatives. This guide covers eight of them, with prices checked on September 16, 2026, and a plain explanation of what each one can and cannot measure.
We make Zutrix, and it is on the list, so read our entry with that in mind. Zutrix does not estimate total traffic the way Similarweb does. It tracks the keyword rankings that create organic traffic, which is a different and often more useful signal. We explain the difference below.
What Similarweb measures, and why alternatives differ
Similarweb models a site's total visits from all sources: search, direct, social, referral, email, and ads. It blends clickstream panels, ISP data, and its own crawls. That is its strength. It is also why it costs so much and why the numbers can be far off for smaller sites.
Most Similarweb competitors do something narrower. Semrush, Ahrefs, and SE Ranking estimate organic search traffic from the keywords a site ranks for. That is more precise for SEO work and useless for social or email. Pick the tool that matches the question you actually ask.
| Question | Similarweb style tools | SEO suites | Rank trackers |
|---|---|---|---|
| Total visits from all channels | Estimate | No | No |
| Organic search traffic | Rough estimate | Estimate from rankings | Real positions, no estimate |
| Keywords they rank for | Some | Yes, large lists | Yes, the ones you track |
| Traffic from ads | Estimate | Estimate | No |
| Referral and social sources | Estimate | No | No |

The best Similarweb alternatives, reviewed
1. Semrush Traffic Analytics
Semrush
The closest paid match, sold as an add-on
- Price from
- $139 a month for the SEO plan, Traffic Analytics costs extra
- What it shows
- Total visits, sources, top pages, audience overlap
- Free option
- Free account with 10 requests a day
Semrush is the only tool here that tries to do what Similarweb does. Traffic Analytics models visits from all channels using clickstream data. It is an add-on to an already expensive suite, so the total can pass Similarweb's price. If you also need Semrush for SEO work, the bundle makes sense. Compare the two in our Semrush vs Similarweb guide.
Semrush: pros and cons
Pros
- All-channel traffic estimates like Similarweb
- Huge keyword database alongside
- Public pricing
Cons
- Traffic Analytics is a paid add-on
- Total cost can match Similarweb
- Per-user fees
2. Ahrefs
Ahrefs
Organic traffic estimates from the largest keyword index
- Price from
- $129 a month on Lite, $29 on Starter
- What it shows
- Organic traffic estimate, ranking keywords, top pages, backlinks
- Free option
- Ahrefs Webmaster Tools for your own site
Ahrefs estimates a site's organic traffic by multiplying every ranking keyword by a click model. It says nothing about social or direct visits. For SEO competitor research, that is usually all you need. The Starter plan at $29 is enough to check a handful of competitors a week.
3. Zutrix
Zutrix
Real positions instead of estimates
- Price from
- $19 a month weekly checks, $29 daily
- What it shows
- Exact ranking positions for competitors on the keywords you pick
- Keywords
- 250 to 10,000 tracked
- Free option
- 7 day trial for $7, free SERP checker
Zutrix takes a different route. Instead of modelling a competitor's traffic, it tracks their real positions on the keywords that matter to you. Add a competitor domain to a project in the Rank Tracker and you see where they rank every day, with a screenshot. Pair that with search volume from the keyword tool and you have a traffic estimate you can explain.
Where Similarweb wins: any question about non-search traffic, and market-wide numbers across thousands of sites. Zutrix answers "who is beating me on my keywords" rather than "how big is that company".
Zutrix: pros and cons
Pros
- Exact daily positions, not a model
- Screenshots to back up every number
- A fraction of the price
- AI search visibility included
Cons
- No total traffic estimate
- You choose the keywords, so you can miss some
- No referral or social data
4. SE Ranking
SE Ranking's competitor research shows estimated organic and paid traffic, ranking keywords, and top pages for any domain. It starts at $129 a month and includes a rank tracker with 2,000 keywords. Good for an agency that wants research and tracking in one bill.
5. SpyFu
SpyFu is $39 a month and stores years of history on the keywords a domain has ranked or advertised for. Its traffic estimates are rough, but its ad history is the best value on this list. If your real question is "what is my competitor spending on Google Ads", start here. See SpyFu alternatives if you need more.
6. Serpstat
Serpstat starts at $50 a month and estimates organic traffic and keywords for any domain, with strong coverage in Europe. It is a fair budget pick if you also want rank tracking and audits.
7. Ubersuggest
Ubersuggest shows a traffic estimate, top pages, and keywords for any domain from $29 a month, or three free searches a day. Estimates lag the bigger tools. It is fine for a quick sanity check on a small competitor.
8. Google Analytics and Search Console (free)
For your own site, nothing beats real data. Google Analytics counts every visit by source. Search Console shows every query, click, and position. Use them as the truth when testing any estimate tool. They show nothing about competitors, which is the whole reason Similarweb exists.
Free Similarweb alternatives
- Similarweb free version: limited data on a few domains a day. Enough to size a market, not to track it.
- Google Trends: relative interest in a brand or keyword over time. Free and surprisingly useful for comparing two competitors.
- Google Search Console: your own real positions and clicks.
- Ahrefs Webmaster Tools: your own organic traffic estimate and backlinks.
- Zutrix free tools: live SERP checks and keyword volumes for any competitor keyword.
