If you'd like to analyze the organic traffic only by tracking a subdirectory (or folder) of your website, a couple of options can do the trick.
1. The first option is to create a custom segment in the Organic Traffic module. You can filter the organic traffic based on the landing page rule, like in this example, where you will see traffic coming from landing pages containing "/blog/."
Together with this, you can create a smart group in the Rank Tracker with the same rule, only to look at the keywords you're tracking that trigger landing pages containing "/blog/." And you can also bulk import corresponding desired landing pages, to make sure you know when you're not ranking with those for the set of keywords.
The GSC and GA profiles for this campaign can be created based on the domain for its market, pulling all the traffic hitting the main domain. The traffic will then be segmented within SEOmonitor.
Moreover, this group can then be individually analyzed in the "Competition" tab as well, with its specific competitors, so you can see how your competitors are ranking on the same keywords that are triggering your "/blog/" pages.
2. The second option is to create different campaigns for each subdirectory or folder with respective locations and track them separately. This can particularly be useful if the subdirectories or folders are for different markets. For instance, "domainname.com/fr" and "domainname.com/en" could represent different countries and thus require pulling traffic from different markets.
For this, you'd need to have their separate GA and GSC profiles or a filtered GA view and a separate GSC profile, so that localized traffic can be pulled (and later, the data from GA and GSC can be appropriately matched to give you accurate traffic data).
If this is the chosen option, you will also see ranks for the specific folder LPs alone, and not for the main domain.
If you have subdomains instead of folders, you can also track them.
