In general, we recommend a minimum audience size of 1,000 homes for a single storm campaign. If you draw a polygon that includes fewer than 1,000 homes, you will receive the following warning message.
Wondering why our recommended audience is 1,000 homes and up? Although PSAI technology provides very accurate targeting capabilities (down to the individual home level), there's a balance that has to be struck between precision and engagement.
Due to Facebook's advertising algorithms, a very small target audience is much less likely to gain traction and be effective in generating leads. Small campaigns may even get stuck in the "learning" phase, which prevents your ad campaign from becoming active.
The larger the audience, the better engagement your ad will receive on Facebook and the more optimized its placement will become.
