Referral Traffic from Semalt

Have you noticed strange referral traffic from a website called or in your Google Analytics traffic sources report?

Yes I’m talking about! I noticed this while analysing the referral traffic for one of my campaigns in Google Analytics & to my surprise the referral traffic generated by is always the highest with 100% bounce rate, which is an indication that it’s not quality targeted traffic. With this factor in mind, I thought of checking the same for other campaigns and again was present there as well.

After discovering this referral traffic source, in order to investigate more I went to the website and found that it is a web analytics company & this is what they proclaim themselves as -

“Semalt is a professional webmaster analytics tool that opens the door to new opportunities for the market monitoring, yours and your competitors’ positions tracking and comprehensible analytics business information.”

But why it is seen as my Referral Source? More about Semalt Crawler as follows -

Semalt crawler is a technical bot of the webmaster analytics tool The algorithm is designed to visit websites and gather statistical data for their service simulating real user behaviour like Unique IP, Browser, Display Resolution etc. They have 100% bounce rate and provide an assurance that their bots never click on advertising banners (CPC, CPA, CPM systems) or extend links (I doubt!!!!). Also, their experts have confirmed that the visits are generated automatically and in random order.

Semalt may cause the following damage (Metric Level) -

  • Total Visits – Each time the bot hits your site counts as a visit
  • Bounce Rate – Each Semalt fake visit counts as a bounce, falsely inflating your bounce rate
  • Pages Per Visit – Each Semalt crawler visits only 1 page, a low and bad number that drives down your pages per visit average.
  • Conversion Rate – If you have goals or ecommerce conversions, Semalt visits never convert. They drive down your website’s conversion rate.

Semalt Team has provided a feasible solution in order to eliminate our site from the list of web resources to prevent it from future visits. Its simple add the campaigns in the field as shown below ( -

As per Semalt Team, our website will be eliminated from their database in a span of 30 minutes post submitting the domain name.

That was the standard step to eliminate Let’s check other methods to exclude or remove traffic from Let’s check out the probable ways as mentioned below -

  • Excluding the traffic from by creating a custom filter: Click here for a video demo to setup this filter
  • Automatically Exclude Known Bots in Google Analytics: Google Analytics has now introduced a new feature in the settings area where you can automatically filter out known bots.

  • Excluding the traffic from using .htaccess file: Using .htaccess files available on most Linux based hosting plans of our campaigns, adding the following lines will solve our problem:
RewriteCond %{HTTP_REFERER} semalt\.com [NC]
RewriteRule .* – [F]
RewriteCond %{HTTP_REFERER} ([^.]+)\.semalt\.com [NC]
RewriteRule .* – [F]

This will return a status code 403 (Access Forbidden) anytime the Semalt robot attempts to access the site thus not only blocks the robot, but also of course eliminates that traffic from our analytics data.

Step1: Click on “Advanced” next to the search box above the table of data for all your traffic

  1. FYI, I added myself to their opt out list months ago and am still seeing their referral traffic. The only way to get rid of this is by excluding it through analytics itself.
