On one of our primary keywords Google is swapping out (about every other week) returning our home page, which is more transactional, with a deeper more information based page. So if you look at the Analysis in Moz you get an almost double helix like graph of those pages repeatedly swapping places. So there seems to be a bit of cannibalizing happening that I don't know how to correct. I think part of the problem is the deeper page would ideally be "longer" tail searches that contain the one word keyword that is having this bouncing problem as a part of the longer phrase.
What can be done to try prevent this from happening? Can internal links help? I tried adding a link on that term to the deeper page to our homepage, and in a knee jerk reaction was asked to pull that link before I think there was really any evidence to suggest that that one new link made a positive or negative effect. There are some crazy theories floating around at the moment, but I am curious what others think both about if adding a link from a informational to a transactional page could in fact have a negative effect, and what else could be done/tried to help clarify the difference between the two pages for the search engines.
