SEO is the process of improving a website's ranking on the search engine result page. Getting 100% SEO basically means that your website will be the first when a certain query is searched. There are several things you can do to improve your website ranking, like ensuring that all pages are working and that they have Meta tags like Meta title, Meta description, and alt tags on images. All pages have headings and subheadings, etc.
You can do all of this or contact a professional SEO Service Provider who has experience in the same and can do it for you.
