The Ads title looks like:
<div class="newtab-site" draggable="true" type="sponsored">
<a class="newtab-link" title="CITIZENFOUR
<input class="newtab-control newtab-control-pin" type="button"
title="Pin this site at its current position"></input>
<input class="newtab-control newtab-control-block" type="button"
title="Remove this site"></input>

The ads work completely offline.
