Why you should pay attention to this algorithm update
The fact remains that the new page experience metrics should be taken seriously by developers and all those involved in optimization strategies to improve search rankings.
To begin with, if your user experience is seen as being in the top bracket, visual cues will guide consumers and browsers to your page over the others.
Google itself is pretty clear about the increased weight age they’re going to give to page experience. After all, a terrific page experience lets people get more done and increases engagement.
It seems evident that those pages which fall below the new benchmarks are going to be left behind in the rankings. This means a significant drop in traffic.
Google already considers hundreds of aspects to determine rankings. The inclusion of page experience lets them guide people, so they can access information more easily and enjoyably.
For site owners and others, understanding these signals and making the necessary changes should be a priority.
Otherwise, you run the risk of your page being ignored. You wouldn’t want that now, would you?
