On-site SEO (also known as on-page SEO) is the practice of optimizing elements on a website (as opposed to links elsewhere on the Internet and other external signals collectively known as “off-site SEO”) to rank higher and earn more relevant traffic from search engines.

Both aspects hold equal importance, while on-site marketing creates and adjusts search engine-friendly content, leading to an improved ranking of SERP (search engine results page). One approach to improve rankings with on-site SEO is to add more pages to your site. Each time you distribute a blog post or add a page, you give your webpage a new indexable and searchable page. 

Off-site SEO marketing is to promote the website on the web. It is done by providing links to your website directly from other websites of the same niche or by managing the social media marketing feed professionally. Off-site SEO refers to optimization techniques you use outside your website to improve organic rankings in the search engine result pages. At its core, Off-site SEO’s primary purpose is to increase the number of high-quality links to your website.
