Big Change to Google Search

In 2010, Google made a huge change to it’s search algorithm (that’s all the behind-the-curtain calculations that go into deciding what results to show for a query string). Yesterday they announced, via a blog post, a tweak to that algorithm which will give preference to more recent results on some kinds of searches–that is, if they determine that a query will benefit from newer sources (say, a search for “Occupy Wall Street”) they will deliver newer results at the expense of relevance.

Google estimates 35% of searches will be affected. That’s a huge number.
