That makes sense.

I just think it's funny that conceivably, I could be searching for particular information (i.e. how to "ABC"), and there could be a page that contains the Holy Grail of what I am looking for. However, none of that matters. I may never find that page because perhaps the site owner isn't in business to appease Google and doesn't care about creating backlinks. As a result, Google gives me some completely irrelevant results. I'll only see sites that provide information on "how to XYZ." Because even though this isn't relevant, they sure do have a lot of backlinks. Well, that is until Google decides to make some other unrelated aspect OF "relevance" the most important factor FOR "relevance."
