I know that semrush shows search engine traffic. What is the calculation of the data?? Is it monthly or yearly? For instance, for DP, I am seeing 244K, is this traffic data per month or it it yearly?
The calculation of the SEMRush data is monthly of course. An estimated traffic goes only from US Google version, according to 40 millions popular keywords.
The data that is displayed by the keyword research tool semrush.com. That is what he is referring to as 'semrush data'. I am not sure what time period it comes from. There must be an indiciation of the time in the faq on semrush site. please check there.
