Sometimes my ad doesn't appear, and other ads appear where mine should be. Why is this?

Some ads are setup in a rotation with other ads. This means that your ad shares a space with one or more ads from other advertisers. You will still get the impressions that were estimated for the space when you purchased it, but you will not see your ad on every visit or page refresh.
