After fighting the urge to improve, it finally comes down to facing the beast and replacing a few links that don't go to valid advertisers pages anymore and actually find links for the pages that have none. The changes themselves aern't the hard part, it's going through the advertisers catalog to find relevant links for each of the unique pages. One of the last changes made to this site were updating the search box advertisment, it seemed that changing a large quantity of pages at once may have caused a temporary dip in popularity, so this time the changes will be made and uploaded a few pages at a time.
Tracking the links was easy enough and from a couple angles. One is from the current third party advertiser of the products, the other is installed,
AXS Visitor Tracking. The outgoing links are tagged with a string that leads through the tracking script and is one of the few uses this script has of this kind.
It does not track forms at all. The tracking also shows other popular pages needing to be varified for correct advertising content.
This project does have a common theme outside of the advertiser being the same, the links are mostly to vital records of some sort or complete collections of data for each of the individual states. Basically, a search run on the advertiser for the name of each state usually gives a list long enough to find what fits the page.
