Basic understanding of advertising allocation algorithms

[orderfromchaos]

Hi I’m in the process of developing a marketplace web application that will provide different levels of advertising priority based on ad spend. I’m trying to get a basic understanding of how this prioritization is translated into a working algorithm. For example: If we have 3 tiers of advertisers - free, $1, $2 - and I want to rotate them so they all appear on search results but with a different frequency for those who pay more, is that something that is easy to implement? And, what kind of professional has the specific knowledge and experience to do this?

Here’s an approach…

Pick a random number between 1 & 3

If 1

Display a random advert from tier 2 pool

If 2

Display a random advert from tier 2 and tier 1 pool

If 3

Display a random advert from tier 2 and tier 1 and free pool

Hope thats useful.
