The top four codes are designed to locate WordPress blogs that allow for commenting. The middle group is designed to find Expression Engine blogs, and the bottom group is designed to find BlogEngine blogs
Expression Engine and BlogEngine are both popular among academics and some government agencies for some reason, which is why we like to focus on those in additional to WordPress.
Since WordPress is the most common blogging platform, however, we’re usually able to get our 10 links without going beyond the first 4 “Authority Codes”.
QUICK TIP: If your search returns zero results, broaden your keyword phrase a bit (i.e. go from “dog walking” to “dog”).
