Google looks at a raft of things before it brings your website to the SERP. Historically, it uses over 200 ranking factors, and some of them prevail over the others. Think mobile-friendliness, backlinks, website security, authority, page speed, and content. These factors are still the biggest signals to optimize for in 2021, although they are not the only ones here. Google is about to put another update into practice, which will cast a new look at page experience. Remember the May 2020 core update that has turned many Google rankings upside down? The new one may provoke the same uproar. Scheduled for May 2021, this update adds new signals to existing Google search ranking factors. It’s important to gear up for it until it’s in full swing.
