Page Speed & How it impacts your SEO
In 2010, Google announced that page speed would impact your website ranking. It actually refers to the time visitors have to wait until your page is completely loaded. On average, a page load for e-commerce website takes seven seconds meanwhile the ideal load time is around three seconds or less.
As a matter of facts, it has an impact on your audience user experience (UX). A bad UX can cost you a loss of revenue if your target have to wait too long to get what they are looking for. They will just close your website. And above all, a slow page load is penalized by the search engines and has an impact on your ranking, both on mobile and desktop devices. Google says:
“A search result for a resource having a short load time relative to resources having longer load times can be promoted in a presentation order, and search results for the resources having longer load times can be demoted.”
Actually, Google compares your site to your competitors on a specific segment and attributes a bonus point whether you are the fastest. But be careful, that marks is not given unilaterally : it takes in account the country, device or network.
So, there is a few factors you should focus on to improve your page speed.
