Let me begin by saying that all of my websites are small, less than 50 pages, because i spend a lot of time researching everything I write about, and also because I hand-code all of my pages. Until about two years ago, many of my articles were number 1 in Google search for their main key phrase, often even outranking wikipedia and large organizations. I should mention that all of my sites are strictly non-commercial with no products or ads, and that the articles generally don't relate to high-volume commercially competitive search terms.
Anyway, about two years ago, many of the articles that had ranked number 1,2, or 3 in Google for a long time, began to slowly slip downward. Two of the sites were hit by the first rollout of Penguin, and haven't recovered, but even on the three non-Penguinized sites, the rankings have slowly slipped. In all cases they have been replaced at the top of the results by wikipedia and large organizations.
[Note: My sites are still ranking very well in Bing, with hardly any of the slippage that has occurred on Google.]
From what I've read and observed, many other small websites have also fallen in Google's rankings over the past couple of years.. So my question is, has Google been adjusting its algorithm to promote the rankings of larger websites at the expense of smaller sites? And if so, why would they do this?
