How does SEMrush calculate traffic?

SEMrush provides accurate traffic estimates and provides this in the Overview, Landing Page and Discovery Reports tools.

Estimated traffic is calculated by multiplying the click-through rate by the keyword search volume and then dividing by 30 (the number of days in a month). The probability of a customer clicking on a website is higher when it is higher on the search engine results page and ultimately means that there is a higher chance of the click-through rate being greater when a website is in those top 1-10 positions.

Whilst you need to take these metrics with a pinch of salt, they can provide a fairly rough estimate of how much traffic you or another website will be getting every month.

How often is SEMrush data updated?

The SEMrush database is updated on a weekly basis. This means that the ranking data, keyword data and website data are relatively fresh and means you can make informed decisions that are reasonably accurate.


No SEO tool is going to be 100% accurate in terms of the data it provides and when it comes to research, whether that be your competitors or of a particular niche, you should always try and get as much information as you can.

SEMrush data is one of the more accurate sources in comparison to other SEO tools that are available. It is updated on a weekly basis and provides comprehensive information on keywords, organic traffic insights and search position data that can be extremely useful for any online business.
