Building footprints is something that can be a challenge, but this video breaks down what a footprint is and how its made. If you take the basic concept of a footprint, build what you need, test it in a browser, and then put it in scrapebox you can get great results.
Also understanding google and other engines advanced operators can allow you to really zero in on what you want, while still applying a minimum effective dose. Its always a good idea to try and build footprints that don’t use advanced operators, that way your IPs will not get blocked as quickly,which makes scraping urls easier.
