All You Should Know About Google AdSense Link Unit Ads
Link ads display a set of text links relevant to the content in a single ad unit. Google offers both horizontal and vertical link units to optimize the space usage of a webpage especially if you want to display more content in a single page along with ads. Image and text ads occupy considerable space where as a link ad unit can be placed in a very small space. A vertical link unit (120 x 90 or 200 x 90) consists of two or three links together and a horizontal unit (728 x 15) consists of 3 to 4 unites together in a single ad unit.
How Does Link Ad Unit Work?
Link ad unit is different from other AdSense ads since link unit itself is not considered as an ad. And clicking on it will take you to the real advertiser’s page showing the ads. The picture below explains how does a link ad work.
Due to the fact it’s not an ad by itself, Google permits AdSense publishers to click on their own link ad units and publishers are not permitted to click on the ads in the resulting page.

Responsive Link Unit Ads
Generally the problem in using horizontal link unit is that it will not fit on mobile devices. In order to overcome this issue, Google introduced responsive link units so that the ad display will be automatically adjusted according to the viewing device. When you create a link unit select “Responsive Links” and generate the ad code for creating responsive link unit ad.
