Since the total number of nodes depends on the size of the page, break large pages into multiple smaller ones to reduce the total node count.

Most of the time, your theme is responsible for adding redundant DOM nodes to your site. Activate the default TwentyNinteen theme, and compare the performance score. If the score improves, that means your current theme is the culprit, and you should either use another efficiently coded theme or work with the developer to see what changes can be made.

The score depends solely on the total number of nodes found on the page. The median is 1400 nodes; however, for a perfect score, your DOM’s total nodes should be lower than 275. Try the following to improve your score:

Everything inside your document is a node - HTML tags, text inside the tags and comments. These nodes have a hierarchical relationship, making a tree of nodes called the DOM tree. A large DOM tree harms your network efficiency and load performance as the browser has to parse lots of nodes that aren't displayed above-the-fold. Additionally, a large DOM tree increases memory usage, requires massive style calculations, and produces costly layout reflows.
