Search Admin Data

Hi,

I have recently started a project at work where we are looking to improve the search functionality in SharePoint. 

We are using the search Admin Data to identify top search terms and make sure theirs an effective use of meta data and where applicable items are bookmarked so that results appear at the top of a search query.

On the data we have downloaded from search Admin one of the columns shows "average position of result" however the numbers are confusing and theirs no detail on what this number is generated from and I wondered if anyone could explain how this number is calculated and what it means.

I've attached a photo of the results but if this is pointing towards it's average position on the page when a term is searched I expect the number to be at least 1.

Appreciate any help
