SEO is an acronym for “search engine optimization.”

Google presents the site on the first page of a query if the site has good SEO.

1. Use a good web hosting provider
2. Use SSL (not http://mysite.com but https://mysite.com)
3. Optimize all your images with alt tags
4. Not duplicate the content
5. Create proper permalinks
6. Create a sitemap in XML
7. Create proper SEO  titles and meta tags, paragraph titles, and bodies.

There are online SEO Tools and you maybe can also find them in https://codecanyon.net/ or elsewhere.

The idea is to see in Google what the people want to know, then you create a list of words. You must use these words in meta, title, paragraphs title, and body in order to be your site in a good position in Google.
