It is back in 2009 when Matt Cutts, in his blog wrote about Google incorporating the consideration of site speed while awarding good ranks to websites. However, Matt Cutts assured that this system did not have deep impact in large set of rankings. It does not even cause big nerve wrecking troubles to the site owners. Still, there is every reason to take the site speed seriously, as it improves user experience apart from passively controlling the site’s rank.
At that time, Google did not divulge clearly, how and through what metrics it was going to use for making page-loading speed a deciding factor for its rank. The patent on that matter released by Google on 4 February explains it with details. It explains that between two resources with information about the same query, the fastest loading site will be preferable to the visitors.
The ‘PageSpeed Insight’ tool by Google helps sites to understand how well they score on the basis of certain rules that are involved in the process. The patent has clear indication about the rules that are followed in this process. However, a little technical help from developers or people experienced in site-speed optimizing might be required for implementing them.
The patent focuses on certain points like, the number of images used in the site, the size of its resource, the web server, the network connection’s involvement in the loading of its resource, etc. While, comparing the loading speed between two resources Google usually confine itself to the devices being used in the same nation and that using the same browser.
The patent also contains details about how the tool can predict the probable loading time of certain pages and sites. Till now, it is not going to show the details about resource’s loading time on mobile devices. The factor is hardly going to make a huge impact on the page rank until and unless comparison is being made between two sites with very similar amount and type of information. Higher loading time can get a site demoted to a lower page rank, based purely on user experience quality.
