Online marketers, primarily those that breathe and live Google woke up to a small surprise in the form of a video released by the search engine giant. The video did not reveal how Google actually ranks websites as many news publications out there might be eluding to. It does however confirm how frequently Google updates it's search algorithm and the procedures they take before releasing these updates to the public.
Amit Singhal confirmed that "just last year, we launched over 500 changes to our algorithm. So by some count we change our algorithm almost every day, almost twice over". Scott Huffman, Google Engineering Director, continues by stating that they "analyse each potential change very deeply to try to make sure that it's the right thing for users". He adds, "In 2010, we ran over 20,000 different experiments. All the data from the human evaluation and the live experiment are then rolled out by a search analyst".
This video discusses how Google identifies, tests, and implements tweaks to their algorithm in their quest to server it's users with the best content that they are searching for. As an example, the video then looks at the reasoning and test procedures that affected the "did you mean" and "showing results for" change earlier this year.
