Where do the numbers in these guides come from?
From our weekly research: every Monday we read up to 2,000 of the most-bought US native ads from public native ad libraries, sort every ad into a space and group the winners into winning formulas. The guides count ads, advertisers, days running and placements. They never include anyone’s clicks or sales.
How often are the guides updated?
The guides built on research (headlines, how long ads run, images that win) update with each week’s research. The specs and rules guides are checked against each network’s help pages and dated.
Are these guides only for Taboola?
No. They cover Taboola, Microsoft, Outbrain, Revcontent and MGID. Where a network differs, the guide says so, and each network has its own page.
