Start with Similarweb or Semrush for a dated estimate of total website visits. Use Ahrefs for estimated Google search traffic. Verify the metric, period, and geography before comparing tools.
Semrush put SEOptimer at about 919,000 visits in October 2026. Similarweb showed about 467,000 for the same domain in its October report. If you were sizing up this competitor for a strategy meeting, the number you copied would depend on which tab you opened.
I’d start with Semrush or Similarweb for a dated estimate of overall traffic. For the question “Which pages are getting found in Google?” I’d start with Ahrefs. Both questions sound like “How much traffic does this site get?” They lead to different reports.
What five traffic checkers showed for the same site
We checked publicly accessible reports for seoptimer.com on November 15, 2026. We used the domain rather than an individual page and recorded the metric and reporting period where the report showed one. This checks what a reader can get from each public report. SEOptimer’s first-party analytics were unavailable, so the results show where estimates disagree and which comparisons are possible.
| Traffic checker | What it showed for seoptimer.com | What I’d use it for |
|---|---|---|
| Semrush | 919,060 estimated visits in October 2026 | A dated estimate of overall traffic and its trend |
| Similarweb | About 466,600 in the comparison panel of the October 2026 report | A second total-visit estimate and audience context |
| Ahrefs | About 270,400 estimated monthly Google organic visits from the US in the snapshot | Finding organic keywords and competing pages |
| StatShow | 384,420 estimated monthly visitors with no clear reporting month beside the figure | A quick lookup that needs a dated source before you use the number |
| SiteWorthTraffic | 984,150 estimated monthly unique visitors alongside an Alexa rank, with no clear reporting month beside the figure | An example of why source and date checks matter |
1. Semrush for a dated total and trend
The Semrush overview explicitly showed October and plotted the previous two months. That makes it easy to check whether an apparent lead is a one-month spike. It also showed an organic-search figure of about 428,000 in a separate section. If you grab the organic number from one report and the total visits from another, the difference starts with what you chose to count. Semrush’s SEOptimer report · Semrush on its two traffic metrics
2. Similarweb for a second view of overall traffic
Similarweb displayed about 466,600 for SEOptimer in the October report’s comparison panel. Its traffic and engagement section also estimated a 2.48% drop from the prior month, while Semrush’s total visits section showed a 13.61% drop. Both pointed down. The size of the drop depended on the provider, so I’d check another month before using either percentage to explain a change. Similarweb’s SEOptimer report · Similarweb data methodology
3. Ahrefs for the searches driving the estimate
The public Ahrefs snapshot put estimated US organic search traffic at about 270,400 monthly visits and surfaced queries such as “free seo audit.” That gives you a search result to inspect and a page to study. Ahrefs estimates Google search clicks from rankings, search volume, and expected click-through rates. Its US organic estimate belongs beside a comparable US organic figure.

4. StatShow for a quick lookup with limited context
StatShow returned 384,420 estimated monthly visitors. The number appeared without a specific reporting month beside it, and the label said visitors. Put that figure in a notes column if you’re gathering leads for research. For a monthly benchmark, use a report where you can verify the period and metric. StatShow’s SEOptimer report
5. SiteWorthTraffic shows why you should check the source date
SiteWorthTraffic displayed 984,150 estimated monthly unique visitors alongside a global Alexa traffic rank. Alexa.com retired in 2022. The report didn’t give us enough information to establish how recent the visitor estimate was, so I’d leave it out of a current traffic comparison.

How to check whether a traffic estimate is usable
Start with the decision. For broad competitor sizing, line up total-visit estimates for the same month, domain scope, geography, and device coverage. If the estimates still differ, show both with their sources. For an SEO decision, pull the queries and ranking pages. A result you can open and inspect gives you a better starting point for deciding what to build or fix.
If you own the site, use GA4 for measured sessions or users and Search Console for Google organic clicks. Match the closest metric you can and carry the difference in definitions into your notes. SparkToro’s 2022 research compared third-party data with Google Analytics for 641 sites. Its results varied by site size, which is a good reason to check an estimator against a site you know before using it to size one you don’t. That study used its own sample and period.

Once you’ve found a rival page worth studying, compare it with the page on your site that serves the same buyer. Check what the competitor explains earlier, what proof they show, and how easy it is to take the next step. That’s where we use SavageAudit on our own site.

Common questions
Which website traffic checker should I use first?
Start with Similarweb or Semrush for a dated estimate of visits across channels. Use Ahrefs when you want to research estimated Google organic traffic and the keywords behind it.
Why do Semrush and Similarweb show different traffic numbers?
They use different data and estimation models. Before comparing them, check the month, geographic and device coverage, and whether both figures measure total visits. The October SEOptimer reports still differed substantially when we looked at their headline visit estimates.
Can I see a competitor’s exact website traffic?
You can see first-party numbers when the site’s owner shares them publicly or grants you access. A public checker generally shows an estimate. For a site you manage, use GA4 for measured visits and Search Console for Google organic clicks.
