On-page SEO and off-page SEO are basically two sides of the same coin. SEO is more effective when practiced with both because Google uses ranking factors that occur on your pages and outside of them. Depending on your needs, sometimes you can focus more on one of those types of SEO. On-page SEO is about optimizing the web pages of your website.
In on-page SEO, your strategy is very much under your control. Off-page SEO, on the other hand, is about improving your SEO through other means, such as creating content and getting backlinks from other websites. These tactics give credibility to your website. If you want to use the best SEO practices, on-page and off-page SEO are great starting points.
On-page SEO (also known as “in-place SEO”) is the act of optimizing different parts of your website that affect your search engine rankings. In-page SEO focuses on optimizing the parts of your website that are under your control, while off-page SEO focuses on increasing the authority of your domain by creating content and obtaining backlinks from other websites. While other factors of on-page SEO have to do with the quality and structure of the content, the performance of your website (and its pages) are also on-page ranking factors. On-page SEO is the practice of optimizing all pages on your website to positively affect your search engine rankings.
The title tag refers to the title of a web page, or the main header you see in the SERP, and is one of the most important SEO factors on the page after the actual content of the page. We'll also detail the steps to optimize your website with on-page and off-page SEO.
