An anchor (sticky bottom) ad stays pinned through the scroll, so it accrues viewable seconds the whole session — often 90%+ viewability vs 50-65% for in-content.

illustrative mobile breakdown:
— In-content avg view 58% ▮▮▮
— Sidebar (n/a mobile) —
— Anchor view 92% ▮▮▮▮▮▮▮▮▮
— RPM contribution: anchor ≈ 18% of mobile total from one slot

High viewability → higher cleared CPM → outsized revenue per impression.

So what: if mobile has no anchor, that's your single biggest open lever. ▲ +18% mobile RPM from one unit.
