Key components of SEO include keyword research, on-page optimization (such as optimizing content, meta tags, and headings), technical SEO (addressing issues that affect website performance and user experience), and off-page optimization (building high-quality backlinks and online authority).

The ultimate goal of SEO is to make a website more accessible to search engines like Google, Bing, and Yahoo, thereby increasing its chances of appearing in relevant search results. This, in turn, can drive more organic traffic to the site, attract potential customers, and boost online visibility and brand recognition.
