How does installing demo content (WordPress) affect the SEO optimization of the site?

Question

Search Engine Optimization

Hello, dear experts, please tell me how the installation of demo content (WordPress) affects the SEO optimization of the site?
We are newbies in this business, we bought a theme that is perfect for our WordPress business, installed the theme, installed demo content, and decided to go the other way, cut off the excess and write the text for ourselves. And we thought about how the demo content will affect the SEO optimization of the site in the future. Please tell me who can give an article. Any information on this topic.
Thanks in advance!

You bought an apartment with a finish that you do not like, and you decided to cut off someone else's repairs in sections. And we thought about how the old renovation will affect the future of living.
Remove demo content and then start indexing the site with new content, and not with “fish” that you don’t need, and then you will be satisfied yourself and no one will say anything about the fact that you have some kind of crap on the site incomprehensible.
