Recent Google Algorithm Changes

Last week Google made two changes in their Algorithms, aimed at improving the users experience of the worlds leading search engine.  Although these were relatively minor changes, they effect the layout of Google’s results pages rather than the ranking algorithms.

More and better search refinements

As of 24th March 2009, when you enter a search query, Google will now recognise ?more and better? associated concepts and will display them at the bottom with the aim of helping you to get to the required websites faster. The example of this as explained by Google is:

?If you search for [principles of physics], our algorithms understand that “angular momentum,” “special relativity,” “big bang” and “quantum mechanic” are related terms that could help you find what you need.?

This feature is based on OrionTM, which was developed by a 26-year-old PhD student from the University of New South Wales and was subsequently acquired by Google.

This is likely to be a first step in a larger integration of Orion?s technology, so we will wait and see what changes Google bring us over the next few months.

Longer Snippets

The second change Google have made in increasing the ?Snippet? (text that appears below the website title) for longer search queries (more than three words). Please read the previous blog post for more information about this.
