SEO cannot be done in single day and the process never ends. You must work regularly to get best SEO results.
I am going to share some important SEO tips to grow your online business.
On-page content changes for search engine crawling
You need to include keyword in your title tag of your HTML page
Use your primary keyword in header tags (H1,H2...)
Use your secondary keyword in header tags (H1,H2...) smaller than primary tag
Design simple navigation starting from your home page
Sitemap HTML and XML must be on your website to simplify search crawler process
Good luck for you SEO.
