Understandably, this is a grey area, since there are plenty of valid scenarios in which a company might make a donation in support of a organization, and may even receive a dofollow backlink in return. I'm sure this is a difficult area for Google to differentiate between valid and abuse cases.
However, we've noticed one site in particular which is almost exclusively relying on charity donations and sponsorships to build their backlink portfolio, and they seem to be succeeding with this. Since 2015, this site (PromoCodeWatch.com) has been making donations to select websites with high authority metrics, and has since built up a rich portfolio of links and is reaching almost one million users per month.
We recognize that it is possible that this website is making these donations simply to support these organizations, and not to manipulate their search rankings. However, when we looked at their link portfolio, we noticed two things:
- 84% of PromoCodeWatch's backlinks are paid sponsorship arrangements or otherwise paid links.
- Some of the organizations they are sponsoring are linking to other spammy sites, further indicating that PromoCodeWatch and other sites are engaging in paid link schemes to boost their rankings.
Below is a table showing PromoCodeWatch's top 100 dofollow backlinks (based on Majestic TrustFlow), showing that the majority of their backlinks are either sponsored / donation links or guest posts. The question is, where is the line between the valid business case of making donations vs. sites that are using this tactic to outrank their competitors?
The donation link scheme appears to be working, and concerned webmasters might wonder how to respond if competitors begin abusing this tactic. I wonder what Google's stance on this issue might be.
