What is Search Engine Optimization?

Quick answer

The practice of improving a website and its content so it ranks higher in unpaid search engine results and attracts more visitors.

Search Engine Optimization, explained

Search engine optimization, or SEO, covers three broad areas. Technical SEO makes sure search engines can crawl and understand a site, through fast loading, mobile-friendly design, clean site structure, and correct use of tags. On-page SEO focuses on helpful content that matches what people search for, with clear titles and headings. Off-page SEO involves signals from elsewhere, especially links from reputable websites.

For example, a plumbing company might publish a clear page about fixing low water pressure, answer common questions, and make sure its location and services are easy to find, helping it appear when local residents search for help. SEO results take time and are never guaranteed, since search engines change their algorithms regularly. Tactics that try to manipulate rankings can lead to penalties.
