We all know tools that show the organic traffic of your competitor’s websites aren’t accurate. These tools just estimate the website traffic and, usually, the traffic they show is underestimated.
In this article, we will know which is the most accurate website traffic estimator.
We’ll test 6 websites that we got a screenshot of from their GSC, and we’ll also check their organic estimated traffic according to 3 tools – Ahrefs, Semrush, and SimilarWeb. We want to see which site is the closest to the real number if we accept the GSC number as the real one.
We’ll measure the organic traffic globally with the 3 tools. We won’t focus on a specific region.
How did we get the websites for this study?
We can’t disclose the websites we used in this study. The category of the website will be shown.
We looked into traffic volumes during January 2022 with GSC, Ahrefs, Semrush, and SimilarWeb.
We take the total number and compare which one of the 3 tools will be the closest to the GSC number.
There was one such study made in 2016 by Screamingfrog, and in this experiment the most accurate website traffic checker was SimilarWeb. The least accurate traffic checker was Semrush.
Let’s see if this has changed in the past 5 years and what the final result is for 2022.
Best Website Traffic Estimator: More about the Methodology
Similar Web doesn’t show a traffic number for months when the traffic was below 5000.
See, it just shows below 5,000.
That’s why we decided to test only sites which had more than 5000. Then we can include SimilarWeb in the experiment.
Ahrefs’ Organic search shows daily organic traffic estimation for the whole month and not a total number for the month. The number changes a lot every day.
That’s why we’ll take the last day of each month as the number.
Let’s check a few websites and compare the GSC traffic with the 3 tools for January 2022.
That’s the only publicly shown website in this experiment.
1. ThriveMyWay.com
GSC: 23.2k
Ahrefs: 23.3k
Semrush: 23.9k
SimilarWeb: 23.2k
The winners for this traffic estimation were Ahrefs and Similar Web. But all 3 were incredibly close in estimating the organic traffic that ThriveMyWay.com received in January 2022.
That’s amazing. I can’t believe all 3 tools are so accurate for this one.
Winner: SimilarWeb, Ahrefs, Semrush [1 point for all 3]

2. Website about Pension and Retirement Planning
GSC: 20k
Ahrefs: 5.8k
Semrush: 16.8k
SimilarWeb: 5.6k
All 3 tools underestimated the traffic, but Semrush is closest.
Winner: Semrush +1 point
3. Website about Beer
GSC: 27.5k
Ahrefs: 69.6k
Semrush: 14.2k
SimilarWeb: 7k
None of the tools is close to the GSC number, but still, Semrush is the closest.
