Smallest detectable lift
Before you pay, the quote shows the smallest detectable lift: the smallest change the study is likely to find if it is really there. A real effect smaller than that will probably come out inconclusive.

Where the figure comes from
It is worked out from how much answers usually vary from channel to channel in past polls on Onflow Ads, and from the number of channels in your study. Where there is not enough history, the quote uses a cautious default and says so.
Reading it
If the quote says the smallest detectable lift is several points and you expect a campaign to move answers by less, the study is unlikely to show it. Consider waiting for a larger campaign.
Making it smaller
- More channels in the campaign, and so more matched channels.
- Questions with a clear target answer, so voters split less at random.
