Top 11 Website Traffic Estimators (Traffic Checkers) for 2019

Jeffrey Bowdoin

The list of website traffic estimators is in no particular order, except that the first 4 are my favorite competitor analysis tools. (Note that the first 4 tools are paid tools, but they are well worth it.)

Each paid tool on this list will give you much more data than the free tools can deliver. Most of them allow you to export keyword data, backlink data, traffic reports, SEO audits, and more.

The rest of the (free) tools on the list are also worth looking into if you simply wanted to get a good guess on a website’s monthly visitors.

1. Ahrefs

Ahrefs is not a free tool. It’s a paid tool – with a monthly subscription fee, similar to SEMrush. If you are turned off of any of these tools because they have a monthly fee, that is understandable. I always try to seek out free tools whenever possible.

But the fact is, you gotta pay to play in the SEO world. The best SEO tools are typically paid tools. If you are looking for the best bang for your buck, Serped, (see #3) is my favorite SEO tool that combines data from many other paid SEO tools, but for a whopping discount compared to if you paid for each solution separately.

Back to Ahrefs – This is one of the most popular SEO tools on the market and for good reason. In fact most SEOs I know either use Ahrefs or SEMrush (or Serped). Those with bigger budgets usually pick ahrefs, and those that want to save a good deal choose Serped. Also many choose SEMrush since it is slightly less expensive compared to ahrefs. I personally really like all three.

There are pros and cons of each, but Ahrefs seems to have a bigger database of keywords and links. However, in terms of measuring traffic, looking at keywords, and other general SEO tasks, Ahrefs and SEMrush are very comparable.

You can look at the organic traffic of a website or a particular page. When I say a Web site I mean the whole website at the domain root level – meaning it will measure visitor data of all the pages combined:

But then you can also dig down further into your /paths or a specific URL:

Other Ahref Features

You can use these methods to gain insight into competitors site. You can also see whether a niche is worth entering. Ahrefs has the benefit of also including a lot of other tools such as:

  • Keyword research
  • Website Audits
  • Competitor Analysis
  • Link Building
  • Rank Tracking
  • Alerts
  • Etc

I’d say another benefit of Ahrefs is that the keyword difficulty metric seems to be a little bit more accurate than the competitors (this could be due to their larger databases, or just better calculations).

Also, their “authority” metric – DR (Domain Rating), seems to be one of the most accurate measurements of a website’s authority.

2. SEMrush

Another main contender in the SEO game is SEMrush. Its the arch nemesis of Ahrefs, and a good contender to be in the top 3 SEO tools ever made. Besides all the other SEO tools, SEMrush is great at analyzing traffic.

Keyword research is another big draw to SEMrush. In fact, this is probably the most popular reason why people like SEMrush:

Similar to Ahrefs, you can type in your website domain or search for a particular URL. You will be delivered organic & paid traffic data and the keywords the website ranks for:

Just like Ahrefs, you can then export this data and do some more analysis in Excel or Google Sheets. SEMrush also has some keyword difficulty metrics as well, however, I find that Ahrefs difficulty is a little bit more accurate. also has an awesome keyword difficulty score/ competitive analysis and is one of my favorite tools to use for competitor analysis.

Despite Ahrefs coming ahead on certain aspects, I still really love SEMrush; they have some great tools such as the keyword magic tool other audit tools that are nice.

I think SEMrush offers a great bang for your buck. SEMrush allows you to do pretty much the exact same thing as Ahrefs, but it is much cheaper.


One of my favorite SEO tools on this list – because there are so many different tools in one subscription, is serped. Under the “what ranks where” tool you can type in a domain and it’ll give you the traffic of each URL.

Note that it does not show traffic of the domain as a whole. This may not be as useful as some of the other tools on this list because it doesn’t show visitor data at the root domain level. So if you are only looking for visitor stats, you may be better off with another tool.

But this comprehensive app is very powerful for SEO in general. This tool is awesome because it also connected to other keyword research tools. For example, simply click on a keyword and you see a whole host of competitor metrics for that keyword. The biggest benefit of this tool is that you literally have hundreds of other SEO tools in one. In fact, serped brings in data from SEMrush, Moz, Majestic and much more.

Considering that this tool starts under at around $79 a month, its actually a very good deal for an SEO tool with so many integrations and functionalities:

For example, if you wanted to check Moz’s DA, PA along with Majestic’s CF & TF (& Trust Ratio), you can conveniently see these metrics with a click of the button:

4. SimilarWeb

SimilarWeb is also a great choice. It’s fairly accurate. And you have the ability to use a free, trial limited version. All you need to do is type in the URL, hit enter and it will bring up several different traffic metrics for you to browse:

You will see the following visitor metrics in a convenient layout:

  • monthly visits
  • monthly unique visitors
  • average visit duration
  • pages per visit
  • bounce rate
  • demographics
  • and more.

You’ll also see the “marketing mix” or the channel overview:

This is nice because it tells you how many visitors the site is getting by channel:

  • Direct
  • Email
  • Referrals
  • Social
  • Organic Search
  • Paid Search
  • Display Ads

You’ll be able to see the referrals of the top referring websites (backlinks to the site). Also, another interesting aspect of similar web is the unique feature of the top referring category:

One best benefit of this tool is it is free – however only to a certain point. If you were on a budget, you can use their free version to check the visitor stats of a handful of websites. However, when your usage increases, you’ll need to upgrade to a paid account.

5. Serpstat

Serpstat is another good all in one SEO tool that includes the ability to analyze other websites traffic data. You can get insight into:

  • Monthly visitors
  • Visibility
  • Organic keywords
  • Ads keywords
  • etc.

The nice thing about this tool is there is a free version you can use, that is limited. The drawbacks to this tool are the visitor data numbers seem to be overestimated by quite a bit and it doesn’t seem to work as well with subdomains – when targeting the subdomain directly.

6. Alexa

Alexa is a very popular and great tool. Alexa has been very popular for a long time. I remember SEOs were using Alexa rank way back in the early days of SEO. Though it isn’t as popular these days, Alexa does have a very useful traffic estimator.

And best of all, it is completely free when using their browser extension. Alexa doesn’t appear to have a free version on their website, but their handy browser extension is. Otherwise, to get more data, you need a paid plan.

You can also create a seven-day free trial, where you can use their traffic analysis tools. If you wanted to upgrade to their website analysis tools it is $79 per month, and with it, you would have access to the following data

  • Monthly unique visitors
  • Audience overlap
  • Site overview
  • Site comparisons
  • Sites linking in
  • Site keywords
  • Site screener
  • Top sites
  • and more.

Free Browser Extension: Alexa has a free extension for chrome and firefox that allows you to check a website’s traffic level. Begin by installing it then activate it. Then when you click the Alexa button it will bring up the traffic rank and the Alexa traffic rate

As far as visitor stats, you want to be looking at the traffic rank in the US. This is actually surprisingly pretty accurate (for a free tool), but it does overestimate it.

Keep in mind that with the Alexa tool (and other tools for that matter), it is more accurate with higher traffic websites. The bigger the site, the more accurate these tools are going to be. Likewise, the smaller websites that you test will be less accurate. This is just the nature of statistics and how Alexa works to calculate traffic.

Essentially, larger websites have a larger sample size that they can draw from, and thus tend to be more accurate.

What about Alexa rank?

There’s also Alexa Rank, which has been a popular metric back in the day for SEOs. It still is for some people. However, Alexa rank is not necessarily showing traffic data.

It’s more of a ranking of all the websites. The lower the rank, the higher the traffic the website gets. Like if you are number 1 (Google), then you get more traffic than all of the other websites.

Is the paid Alexa plan worth it?

Alexa (owned by Amazon) has had a long history as being apart of any SEO practitioners tool belt… However, I found that the paid version of the tool was lacking compared to competitors. For that $80 per month, you’d be much better off with a serped account or SEMrush.

7. Google AdWords Display Planner

Google AdWords Display Planner may not technically belong on this list because it isn’t a competitor analysis tool like the other tools on this list. However, it is worth mentioning just because it is free and offers some good insights (though Google is trying to rid of the standalone version of the tool).

Google Adwords display planner can be used to gain insight on impressions. It also has some nice demographics data as well. However, this tool will not estimate the actual visitor data.

8. Quantcast

Next up on the list is Quantcast. This is an analytics tool mainly directed at measuring and data on your own website. However, there’s also a section where you can research other websites – for free!

Simply type in the URL and hit enter. You’ll then see a traffic graph similar to this (remember these are a calculated guess on what the real numbers are):

Further, you can also view:

  • demographics
  • Audience data
  • engagement data
  • content segments
  • and more.

The biggest drawback to this free Web site traffic tool is it didn’t seem to work with subdomains. For example, I’ve typed in “” and it didn’t work. Then I typed in” and it worked.

9. Visitors Detective

Visitors detective is another popular tool that you can use to estimate unique visitors. The best part about these tools is completely free.!

After you enter a website, you will see the following information:

  • daily visitors
  • Traffic by country
  • Social network data
  • and more

One unique feature (especially for a free tool) is that you can change the date range. So if you want to look at visitor data from one day or 30 days, the choice is yours. Even though it is free, the drawback to this tool is it doesn’t allow you to check subdomains.

Also, it seems to overestimate traffic quite a bit compared to real-world data. It seemed to nearly triple the amount of actual traffic you get. So if you’re getting 2,000 daily visitors in analytics, it may show closer to 6,000 daily visitors. So, again, keep in mind that each of these tools has different metrics (their own scale) that they use and thus should be used only as a relative measurement of a site’s unique visitors.

10. Statshow

Statshow is a great free website statistics tool, which includes a visitor statistic. This tool can show you estimated numbers of traffic from a daily yearly or monthly view.

Statshow also shows you:

  • monthly page views
  • monthly visitors
  • monthly ads revenue
  • different categories and niches for the site
  • Alexa rank
  • Site age
  • And more

The benefit of this is it’s free. The drawback to it is that the traffic numbers don’t look very accurate. It looks like they overestimate the monthly visitors quite a bit.

It will also do some math for you – as it calculates the commercial value of your keywords. You get a similar metric with Ahrefs and SEMrush’s calculation of traffic value:

11. Site Worth Traffic

Another free monthly visitors tracker worthy of consideration is called site worth traffic. This tool will deliver traffic details such as:

  • daily
  • monthly
  • yearly
  • alexa traffic rank
  • alexa page views
  • traffic sources (Taking the data from similar web)
  • Alexa traffic graph

This tool seems like one of the most accurate out of all the free traffic estimator tools. However, it doesn’t look like you can enter subdomains.
