Page Speed Factored into Google Search Rankings - Foreign Translations of Book - PNG Optimization - Broadband Trends - Optimization Week of April 13, 2010

Optimization Week Issue #113, April 13, 2010

After a short hiatus, we've got a content-packed issue for you gentle reader. The big news this week is that Google has now officially announced that the loading speed of a web page is indeed a factor in its search engine rankings. Although the change currently effects only 1% of US-based sites, this is a welcome trend for web usability fans. This additional ranking factor concretely links web site speed with search engine rankings. We show how the psychology of performance and search and business metrics are now even more closely related.

Next, O'Reilly has released two new foreign translations of our book, Website Optimization Secrets. A new Polish translation and a simplified Chinese version are now available on the book's companion site. In other speed news, we show how to maintain smooth alpha transparency in PNG8 and PNG24 files, using a client's site as an example. Finally, we discuss the latest broadband trends with two new articles from the Bandwidth Report.
