The same offer pays different amounts on different sites

Data captured:

The gaps

Widest differences we matched

A sample of matched pairs from the same capture, both sides paying at least $1 — the floor keeps five-cent denominators from dressing up as thousand-percent gaps. Difference is (higher − lower) / lower. The two walls source offers through different advertiser networks, which is the likely cause of most gaps — see the limits below.

The ties

Where the two walls agree

Not everything differs. Entry-level milestones — install the app, open it once — were frequently identical on both walls. This is the part of the table a site trying to sell you a “best site” verdict would leave out, and it is the reason our advice is to check the specific tier you intend to complete rather than pick a site by reputation.
