Of the many factors that Google considers for deciding the ranking of a website in SERPs is page loading time.
Last year, for the benefit of webmasters, the search engine giant launched the Page Speed web optimization service, starting their venture with Page Speed browser extensions, later online Page Speed tool and finally, the Page Speed service. Just a few days ago, Google updated the service and added a rewriter to make websites faster.
This rewriter, which according to Google “Cache and Prioritize Visible Content”, optimizes three things in a site to make it faster.
Page Speed is at present an invitation only service.
If you have a website and want to improve its page loading time, visit the sign-up page: https://docs.google.com/a/google.com/spreadsheet/viewform?hl=en_US&formkey=dDdjcmNBZFZsX2c0SkJPQnR3aGdnd0E6MQ and fill up the form to request access. It’s in the beta phase and completely free. However, industry insiders are of the opinion that Google might charge money once the full version is released.
