Google Link Spam Algorithm Update Rolling Out on July 26
Google begins rolling out the “link spam update,” which makes its algorithms more effective at identifying and nullifying link spam.
The update begins rolling out today and will take at least two weeks to roll out broadly to search results in multiple languages.
Google cautions that changes in rankings are imminent for some site owners:

Information strewn throughout Google’s announcement suggests a particular emphasis on targeting links from sponsored, guest, and affiliate content.

This is an indication that Google wants site owners to pay attention to its advice on how to handle links within content where there’s an exchange of value involved.

Google Link Tag Best Practices
Google reminds site owners to qualify links appropriately when linking out to other sites.
Sites are required to add tags to links where there’s a value exchange between the two domains.
In particular, Google singles out affiliate links and links from sponsored and guest content.
Here’s what Google recommends for each type of link:
- Affiliate links: Google asks sites participating in affiliate programs to qualify these links with rel=“sponsored”, regardless of whether these links were created manually or dynamically.
- Links from sponsored posts: Links that are advertisements or paid placements (commonly called paid links) are to be marked up with the rel=“sponsored” value.
- Links from guest posts: Links from guest posts are to be marked up with the rel=“nofollow” value.
Google adds that it may issue manual actions when it finds sites that fail to qualify the above types of links appropriately.
