I'm wondering whether I can search in google for pages that contain links with specific query parameters. For example, I need to find websites that have affiliate links using Tapfilliate (for example site.com?tap=*). So I need to search for links containing "?tap=".
Is there a way I can do that using Google? Or if you can think of some tool that will help me find such websites.
Indeed you can. That is called (or at least when I learned it in University), Google Hacking. Take a look at this which will give you a small insight on the basic operators you can use.
Google hacking involves things like "searching for certaint words in a title", or in the full page, searching in websites like "pastebin", etc etc etc. It all depends on your creativity to know what to look for.
