On-site SEO (also known as on-page SEO) is a term used to describe optimization within a website that allows search engines to understand pages easily and allows users to find informed answers, quickly. What it really comes down to is making sure that search engines and users are able to understand what your page is about. On-page SEO is the practice of optimizing your webpages to get a higher ranking in the SERPs.
This type of SEO focuses on features you can control on your website, including content, design, appearance, and other technical elements. This is different from off-page SEO, which is optimizing for signals that happen off of your website (for example, backlinks).
With all of Google’s modern algorithms, on-page SEO play a major role in getting your website and content to rank in the SERPs. Behind every query is a real person who wants search engines to help them find something. Search intent (also known as user intent) is the primary goal a user has when searching for a query in a search engine. Users are searching for a specific type of answer or resource as they search.
Keeping your website up-to-date is essential for your success. The content in your web pages should be good and relevant enough to provide visitors a good user experience to make them want to stay longer and visit other pages and content. On-Page SEO is a constant process.
