It is important to remember the location of your audience will play a major factor in the amount you earn. Generally the higher paying countries, have more/higher paying video campaigns available.
For example – UK audiences will generally see plenty of video content, whereas, audiences in Estonia (for example), will see fewer videos, with a lower CPM. It is all down to advertiser demand for audience destinations. Advertisers typically pay more for prime destinations e.g. English spoken adverts – would be prime in English speaking countries.
Please don’t rule out a lack of campaigns at the current time (we call this low fill rates), or a campaign coming to an end. Usually there is nothing to worry about, as campaigns come and go on a regular basis. As a generally accepted view – January and August tend to be particularly difficult months for the advertising industry as a whole, whereas the run up to Christmas for example is usually the most prosperous.
We try to serve at least a banner or remnant ad (non-video) when a video is unavailable (something is better than nothing). This ensures server owners don’t lose out entirely because of lack of fill rates (despite videos paying more). Fill rates fluctuate up and down throughout the year, this is normal – it doesn’t mean our ad server is broken.
