I took over the project from the previous team, who reported having published hundreds of guest posts and outreach links over the past six months. I started randomly checking the sources and discovered something disappointing: quite a few of these web pages weren’t even indexed by search engines—meaning the money went down the drain, and no link equity was passed on to the site.

Of course, you can’t add third-party websites to Search Console because you don’t own them, and clicking through every URL using the “site:” search operator for thousands of pages would drive you crazy. How do others handle this kind of outreach monitoring and indexing verification for a large number of donors? And are there any services where you can simply set up payment via cryptocurrency or PayPal for verified links—without linking a credit card or setting up recurring monthly charges—when you need to conduct a one-time audit?
