SEO (Search Engine Optimization) is the process of optimizing a website to improve its ranking on search engines like Google. The goal of SEO is to improve the position of the website in natural search results, thereby attracting quality traffic and potential customers. For businesses, SEO is a sustainable, effective and low-cost customer approach strategy.

Website SEO is a combination of techniques and strategies that help a website achieve high rankings on Google and other search engines. This includes optimizing the site's structure, content, and other technical elements.

On-page SEO includes keyword optimization, improving page load speed, and using backlinks (internal links) to navigate users.

Off-page SEO , on the other hand, focuses on building credibility outside of your website. This typically involves building backlinks from other reputable websites, participating in online communities, and building social media engagement. Off-page SEO helps increase your website’s credibility in the eyes of Google and improves your overall ranking.
