Run header bidding everywhere, or only your best pages?

Run header bidding everywhere, or only your best pages?

You can add header bidding to every page or focus on your highest-traffic ones first.

— Everywhere at once: maximum coverage, but more places to break, and low-traffic pages add maintenance for tiny gains.
— Key pages first: your top 20 percent of pages usually earn 80 percent of revenue, so you get most of the upside with far less risk.

Tiny example: your homepage and three top articles drive most visits. Perfecting header bidding there beats spreading thin across 500 sleepy pages.

1. Sort pages by traffic.
2. Launch on the top handful.
3. Expand once it's stable.

In plain English: start where the visitors already are, then widen out once it works.
