Google began to implement “link spam update”, which makes its algorithm more effective in identifying and suppressing spam links.
The update will be rolled out today, and it will take at least two weeks for it to be widely promoted to search results in multiple languages.
Google warns that some website owners’ ranking changes are imminent:

The information scattered throughout Google’s ads indicates a strong emphasis on targeting sponsors, visitors, and affiliate content links.
In fact, the ad starts as an informal reminder to mark the attached content with the appropriate rel value.
Google buried the leadership because news about this algorithm update was not mentioned until the end of the blog post.
This shows that Google wants website owners to listen to their suggestions on how to deal with links in content when it comes to value exchange.
Let’s go through Google’s guide, it seems to be particularly relevant to this algorithm update.
Google Link Tag Best Practices
When linking to other websites, Google will remind the website owner to rate the link appropriately.
The site must tag the link where there is an exchange of value between the two domains.
In particular, Google will highlight affiliate links as well as sponsored and visitor content links.
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 added that it can issue manual actions when it finds a website that does not adequately rate the above-mentioned link types.
