Search Engine Optimisation is one of the essential techniques to promote your site. It covers mainly on-page and off the page that helps the site to gain the top position on the search engine results pages.
To optimise the website for search engines you need to follow below basic steps:
Make the site about one thing: The site can be about other stuff but select one primary topic that is important. It also helps you to do little keyword research before choosing a topic.
Put the keywords where they matter most: Keywords are an essential part of SEO, so include them in the proper places like site title, description, domain name, tagline, page content, blog categories, etc.
Link to internal pages: Always link the most relevant pages from homepage directly and cross-linking them with each other.
