We understand that people wants to know how search works. Google has been making a big deal about wanting to be more transparent about its search algorithm. With a control over revealing all the secrets of course, Google has been doing a great job with plenty of algorithm announcements. Recently, the company announced many of the subtler algorithmic and visible feature changes.

Here is the recent list of changes:

Related query results refinements
Sometimes we fetch results for queries that are similar to the actual search you type. This change makes it less likely that these results will rank highly if the original query had a rare word that was dropped in the alternate query. For example, if you are searching for [rare red widgets], you might not be as interested in a page that only mentions “red widgets.”

More comprehensive indexing
This change makes more long-tail documents available in our index, so they are more likely to rank for relevant queries.

New “parked domain” classifier
This is a new algorithm for automatically detecting parked domains. Parked domains are placeholder sites that are seldom useful and often filled with ads. They typically don’t have valuable content for our users, so in most cases we prefer not to show them.

More autocomplete predictions
With autocomplete, we try to strike a balance between coming up with flexible predictions and remaining true to your intentions. This change makes our prediction algorithm a little more flexible for certain queries, without losing your original intention.

Fresher and more complete blog search results
We made a change to our blog search index to get coverage that is both fresher and more comprehensive.
Original content
We added new signals to help us make better predictions about which of two similar web pages is the original one.

Live results for Major League Soccer and the Canadian Football League
This change displays the latest scores & schedules from these leagues along with quick access to game recaps and box scores
