Their search result page is just a ranking of whatever they predict will sell best based on your query (based on units, not dollars). It’s stupidly simlistic, actually: if we sell more for a given search term because we’re advertising hard on that search term, our organic ranking for that term will rise almost immediately. So in your case, what’s going on is that basically other people who search with the same term end up buying other products. Thats bad for you, but perhaps its actually good for them?
