Detailed Traffic Journey Analysis

When we are looking at a detailed Traffic Journey,   our goal is to check what is the incoming source of traffic to our website and what is traffic going out from our website to other sites. Also what is type traffic we are getting into our website i.e is it coming from Google Search, Direct traffic , social traffic or Paid Traffic.

  Both tools provide data on direct, organic search, referral, paid search, and social  traffic types. Besides giving type of traffic, both tools provide a user journey to the website i.e  source from where the user landed on the website and where the user went after the user visited the page.

For this feature, SImilarWeb is providing more data it includes data from Emails and display Ads.

SImilarWeb Wins this round compared to SEMrush.

Traffic to the Most Popular Pages

SimilarWeb used to have a feature called Popular Pages that ranked inner pages by their page views’ share. Recently, the feature has been made unavailable to the wider audience.

Meanwhile, SEMrush Traffic Analytics has the Top Pages report, giving you a list of the most visited pages on a website, counting both internal and external visits. You can filter the ranking by unique pageviews, unique visitors or entrances and also have a look at the entrance sources. Sounds like this feature can lead you to some insightful conclusions and bring another point to the SEMrush tool.

SEMrush wins this round as Popular Pages features are included in the subscription plan. No need to pay additional to access this feature.

Mobile Traffic Data

As per general statistics  , more and more people are using mobiles to browse through the internet, mobile traffic analysis is also an important factor.

Both tools  provide mobile traffic data analysis.

Key difference between these two tools is SEMrush Traffic Analytics, mobile traffic data is fully available under the Traffic Analytics plan but In SimilarWeb, it needs to be purchased separately.

This makes SEMrush a clear winner compared to SimilarWeb for this feature.

Audience Analysis & Demographics

When we are looking at Audience Analysis and Demographics, we are looking at  Audience age, Gender, Interests , Geography etc to understand Audience stats related to traffic coming to your site.  Both tools provide extensive data on this. Let us see the key differences.

With SEMrush Traffic Analytics, you can check the audience overlap between any websites. The subscription also includes the new Market Explorer tool, which helps you discover demographics (age and gender) and interests of the in-market audience. The features also allow you to discover similar websites.

Audience Overlap SEMrush

With SimilarWeb, you can analyze audience demographics, interests, and geography in detail. You will get to see similar websites in the tool as well. However, the audience overlap feature is not available.  

Audience overlap stats will be helpful to check what audience is showing interests in similar websites in your competitor domain. Apart from this , both tools provide good data.

Audience Interests SimilarWeb

SEMrush is the winner in this round due to Audience overlap feature. 

Industry/Category Analysis

SEMrush Market explorer can help doing Industry/Category analysis  by listing relevant websites similar to the one you enter. These are the domains who are in the same market and working in the same industry.

Now the tool has the impressive SEMrush Growth Quadrant that puts all the competitors into four categories, depending on their websites’ audience size and growth rate. This can help you understand market positions of individual businesses, as well as understand the market development and potential in general.

You will get the most accurate picture if you analyze your custom list of competitors in the tool.

Don’t be confused by the fact that such amazing market analysis features belong to another tool — SEMrush Traffic Analytics and Market Explorer are purchased as a one-piece solution. This means, to get access to these reports, you will only need to switch tabs in the interface.

Both SEMrush and SimilarWeb have comparable features and both are winners in this round.

Historical data

Access to historical data is another important factor in Website Traffic Analysis.

SEMrush provides access to Historical data on any subscription since April 2018 while in SimilarWeb  ,the available data range depends on subscription: the basic one includes only 12 months.

Obviously, SEMrush is the clear winner in this case.

API Access

If you are a bigger organization , you want access to traffic data through API to integrate into your internal applications.  Let us see how both tools provide access to API.

SEMrush Traffic Analytics offers API access by request. It can be obtained independently from the interface subscription, which means you don’t have to buy Traffic Analytics if you only need this data for your custom reports or integration to your product. 

In general, data is arranged in a more user-friendly way in SEMrush. For example, to receive all the main stats on a domain, you need to make just one query. Same features, if you need access in  SimilarWeb, it takes three queries. Limit-wise and effort-wise, this is more efficient. 

What truly makes SimilarWeb different is their comprehensible UI. You can clearly see how many API units you have spent and how many you have left. There are even special Similar Websites API and Adult Websites API. So, overall, you can get more data with SimilarWeb API.

SimilarWeb is the winner in this round.


To gauge the data accuracy, data is collected from your own  domain from both SEMrush Traffic Analytics and  SimilarWeb and then comparing stats with what you see in Google Analytics.

As both tools use similar algorithms of clickstream data collection, projection, and estimation, there will be discrepancies in that data as most of the data is based on estimations.

The question is, how big is this discrepancy?

Before we present you with what we’ve found out, we want to emphasize one thing: both traffic analytics tools were made for the competitive analysis that always tells the most when it is compared to similar data collected and what is the deviation percentage

To check the tools’ accuracy, OWOX BI conducted their independent research. They compared data from Google Analytics accounts of 787 anonymized websites with more than 100,000 visitors per month, observed by OWOX BI, with the stats that SEMrush Traffic Analytics and SimilarWeb showed. The numbers in the graph show the % of difference between internal analytics and competitive intelligence tools. The smaller the error, the higher the accuracy.

Traffic data Accuracy
  • Save

According to OWOX, SimilarWeb data accuracy didn’t correlate with website traffic volumes, while SEMrush Traffic Analytics showed a clear tendency to be more accurate for large domains.

SEMrush Traffic Analytics also shows an “Estimated accuracy” sign at the top of the interface. The larger the audience of an analyzed website, the higher the accuracy, the tooltip indicates.

Don’t be scared by the fact that discrepancy exists at all: as this possible error is applied to all the researched competitors’ domains, it shouldn’t distort the picture if you compare them with each other.

SEMrush is providing more accurate data as traffic volume grows giving you dependable data points.   

SEMrush is Winner this round.


Let us compare pricing plans for both SEMrush Traffic Analytics and SImilar Web.

All features for competitive website traffic analysis included in the SEMrush Traffic Analytics tool, all regional databases, and historical info are available for $200/month. You get all the benefits mentioned in this article, including the unbeatable keyword database, by adding any SEMrush subscription — so, the price for the entire package will start from $299.95/month. Most importantly, the price will be the same for every market.

SimilarWeb has a more complicated payment scheme. Each country database must be purchased separately, and many features (top pages, mobile data, etc.) also need to be paid for individually. Even the basic package is expensive and has no fixed price.

What’s more, many features (from mobile data to top pages) also represent individual buys. In conclusion, even the most basic package has no fixed price. One thing’s for sure, though, it’s going to cost you.

This makes SEMrush a clear winner in price point of view as well.

Which tool to choose for website traffic analysis?

Based on the above analysis , SEMrush Traffic Analysis tool gives more options in terms of tools and features for the price you pay for the subscription compared to SimilarWeb. That way, along with Website Traffic Analysis, you also can do detailed analysis of other digital marketing channels like backlink research, Keyword Research , Social Media Research and Paid Traffic research.

You can generate plenty of Website traffic analysis reports with both the tools as well.

If you are still thinking, you are open to exploring more on both the tools. You can do so by signing up trial period access to analyze features and come to a conclusion. As far as me, my vote goes to SEMrush.
