Google recently detailed 17 adjustments it made to search in January, including the Panda 3.2 update.

Google’s Panda 3.2 update, which came in late January, was one of just 17 adjustments to search that the company rolled out in the month. The latest Panda update dealt with site indexing and was launched mostly to update data, according to the company, and SEO marketers should take note. 

At the close of 2011, Google said that users should expect substantial and frequent updates to search. As the company continues its move toward a unified platform of all its services, users will see data from YouTube searches and Gmail content influencing their search results.

Other updates noted in the Inside Search blog include a better-performing freshness algorithm, which the company announced in November. Predictive search features, such as autocomplete and instant, have been improved as well, according to Google. Both changes are aimed at making Google a faster platform and its results more relevant.

More changes will come from the company throughout the year that can impact search engine optimization. However, focusing on the quality of content offered to site visitors will help businesses avoid negative impacts of algorithm changes and drive sustainable SEO practices.

Part of creating high-quality content is encouraging readers to return for information frequently. Brafton recently reported that Google’s Matt Cutts says developing trust through strong content is the best way to boost SEO
