This article published in 2015 describes a project call Accelerated Mobile Pages (AMP) in Google. The project aims to shorten the time needed to load a page on mobile devices by storing a copy of the content in the servers near the readers. One of the reasons that loading the webpages takes a long time is that running the code in the background is not easy, so if the content can be stored temporally in a nearby server, the time needed to reach the content would be significantly shortened when a user clicks on a link.
Google plans to use webpage load time as one of the criteria when calculating page rankings, so those participating in this AMP project may have higher ranks and appear at the top.
In class we’ve learned how to calculate page ranks using hub scores and authority scores. Pages with the highest ranks are the ones referenced a lot by other webpages and contain links to other useful pages. The pages Google considers as “important” and shows to us when we search something are those with highest scores. In AMP project, Google also considers the time needed to load a webpage as a factor of determining the rank of a page. So when we type a keyword into Google, the links we see at the top of the page are not just those Google considered as “important”, they have to be quick and easy to load.
