Search Engine Optimization (SEO) is something worth learning about or at least becoming familiar with. This is the practice of organizing your website so it's "optimized" for the way a search engine catalogs (and then displays) your website in search results.
A good place to start is with the Yoast SEO plugin. This plugin is free with a paid upgrade (when you need it).
Yoast will analyze the readability and accessibility of your content and make suggestions in your website for how you can improve it.
The plugin also gives you a preview of how each post or page on your website would show up in search results. This way you can actually customize the "preview text" that is displayed on a search result.
Here's a video I made (Disclaimer: at least a few years ago) about Yoast.
