Today Amit Singhal a Google Engineer in charge of the ranking team introduced Google’s three core ranking philosophies.
1) Best locally relevant results served globally.
2) Keep it simple.
3) No manual intervention.
He then took the time to break-down each one.
Best locally relevant results served globally
What he goes on to say is that if they run into a problem with a query they use that as method of improving the algorithm or as Amit says it “no query left behind”
Keep it simple
This is in reference to the Google Search Algorithm itself, he basically says that they keep the Algo as clean as possible without any loss of quality to the search.
“Our engineers understand exactly why a page was ranked the way it was for a given query. This simple understandable system has allowed us innovate quickly, and it shows. The “keep it simple” philosophy has served us well.”
No manual intervention
Does Google manually edit their results? According to Amit the answer is No. He actually gives two reasons for this:
1. He says that people have made and contiune to make the web by building pages and linking to sites and they just extract that information through their Algorithm.
We believe that the subjective judgment of any individual is, well … subjective, and information distilled by our algorithms from the vast amount of human knowledge encoded in the web pages and their links is better than individual subjectivity.
2. A query that does not return the results is just an opportunity for improvement to the Algorithm.
Improving the underlying algorithm not only improves that one query, it improves an entire class of queries, and often for all languages.
He also takes the time to point out they will use humans to remove websites in violation of Googles Webmaster policies and for other legal reasons.
