As a website owner, you will, of course, be very interested in inventory forecasting. That is estimating future levels of adverts available to sell so you can work out much money you will be able to make from your site via online advertising. This process is unfortunately not an exact science, as you are attempting to predict the future.
The simplest and most effective way to get a good estimate is to simply use the number of impressions you received from the month before. This amount will increase or decrease slightly (probably no more than 20%), but in terms of getting your estimated figure as accurate as possible, it’s your best bet.
Impression Forecaster
Feel free to use our simply inventory forecaster, which tells you the most likely amount of impressions you will receive next month, and what unlikely scenarios look like.
If your impressions are increasing, expect them to keep going up. If they are decreasing, expect them to keep going down.
Better Forecasting
If you want better inventory forecasts, you will need to keep track of all your relevant data (ad impressions, marketing spend, seasonal user count changes etc) over a long period and try and work out some formula that works for you. We would not recommend doing this however as the amount of time you spend on it will not be outweighed by the benefit you receive from it. Inventory levels change only a little, and inconsistently over time, so if you want to know what next month is going to look like, check out last month and you’ll not be far off.
Many people and companies have tried many complicated and convoluted ways to make their inventory forecasting more accurate, but none have succeeded in any major way. Unless you have a magic link to the future, we recommend you don’t get sucked into trying to outdo them either.
