How to conduct SEO-optimization of the site

[Marikosa]

I want to conduct SEO-optimization of the pages of my site, but I do not know how to do it yet. Who has experience, please tell me where to start and what service can be used?

I try to do regular on-page seo checker and for this I usually use online service https://pr-cy.io/tools/content-analysis/ This checker gives a lot of useful information and if you use it correctly, you can significantly improve the performance of the site. Look at all the features of the service and find out what data for analysis you get after the checker.
