I don't exactly know why that is, but it is very annoying.

Example: I just googled

paizo fall of plaguestone

The first result is on pathfinderwiki.com, followed by Amazon's page of the book, then a bunch of paizo.com forum threads about looking for players on the module.

Okay, maybe I wasn't specific enough. Now googling:

paizo.com store fall of plaguestone

Most of the first pages is forum threads on paizo.com about the adventure, looking for players etc. Then Amazon, a bunch of other different online retailers, the module on Fantasy Grounds, the youtube series GM'd by Jason Bulmahn, Syrinscape, ... but never in the first 5 pages do I get linked to the store page on paizo.com.

What gives? Is there a way this could be improved?

(btw: I'm located in Ireland if that makes any difference.)

Edit: there seems to be a difference between using a desktop and a mobile browser, with the mobile browser actually getting very good results, and the PC browser ... not so much. Very odd.
