I am working on a site and the frequency of updates to the pages on it is around the same, but some of the pages' cache dates change a couple of times a week while other pages' cache dates change every couple of weeks.
What might be the reason(s) that this is happening? Could this be indicative of anything?
I am seeing a similar pattern for these pages in the SERP index.
