How to do better optimization?

Question

Search Engine Optimization

Good afternoon. The question is how to do it right. On the site, I decided to divide styles and java script files into several bundles, and make some of the pages have their own styles of java script files. From the point of view of search loading, this is correct, because the site will load faster. But from the point of view of web development, how it will look like. All these styles are processed by webpack, it creates files itself, makes bundles from me, I just need to connect the necessary styles for the page I need. I am confused by the fact that the webpack config will contain a bunch of commands that few other web developers will not understand. And one more thing confuses me - am I doing the right thing.
