If you want to discover which subdomains your competitors are directing their PPC advertising traffic to the most, look no further than the Advertising Subdomains report.
This report analyzes your competitor’s subdomains by paid traffic, paid traffic %, and the number of paid keywords going to each subdomain.
Much like the other reports within Advertising Research, you are able to expand on certain metrics by clicking on that respective data. In order to expand on the individual keywords linking back to a specific subdomain, you would simply just click on the number of keywords located in keywords column. This action can also be done with the traffic % for the subdomain.
As always, you can export to CSV or Excel to save this data to your research.
