Google decided to retire link ads. This is based on the feedback from users, publishers and advertisers.From 10-03-2021 users 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. Fixed-size link ads will stop serving on your site(s).We will collapse each ad unit where possible. In other cases will show a blank ad.
There is no action required from publishers in relation to responsive link ads as these will begin to serve display ads from 10-03-2021.
