Google AdSense has decided to retire the most popular and clickable ads unit known as Link Ads from its Ads Format, the Link Ads unit will no longer be available come March 10, 2020.

We’ve decided to retire link ads. This is in order to modernize our available ad formats, based on the feedback from users, publishers and advertisers about the Google AdSense ads. Going forward, we’ll be focussing on improving and developing other ad formats to help you grow.
What does this mean?
From 10-03-2021:
You will no longer be able to create link ad units.
Your link ad units will be renamed with [previously link ad unit] added to the end of the ad unit name. This will apply to both responsive and fixed-size link ad units.
Responsive link ads will begin to serve display ad units on your site(s).
Fixed-size link ads will stop serving on your site(s). We will collapse each ad unit where possible. In other cases, we will show a blank ad.
Your earnings
Our experiments show that, for the vast majority of publishers, responsive display ads can perform as well as link ads. We are constantly optimizing responsive display ads to maximize performance.
You will be able to monitor the performance of your link units through the ad units report to compare performance before and after.
What to do next?
There is no action required from you in relation to your responsive link ads as these will begin to serve display ads from 10-03-2021.
