What is SEO?
SEO, or search engine optimization, is the practice of improving a website so it appears higher in unpaid search engine results. It combines content, technical work, and building authority to attract relevant visitors.

How SEO works
Search engines crawl pages, add them to an index, and rank them when someone searches. They aim to show the most relevant and helpful results, so SEO means making your pages easy to find and worth ranking.
Rankings change as competitors and search engines change, so SEO is ongoing work rather than a one-time project.
The main areas of SEO
On-page SEO covers content and page elements. Technical SEO covers how the site is built, crawled, and indexed. Off-page SEO covers signals from outside the site, mainly backlinks, and local SEO focuses on searches tied to a place.
How SEO differs from paid search
Paid search puts ads at the top of results and charges per click. SEO earns organic listings without per-click fees, but results take longer and are never guaranteed.
Common questions
What does SEO stand for?
SEO stands for search engine optimization. It can also mean search engine optimizer, the person who does the work.
How long does SEO take to work?
It depends on your site, competition, and the work involved. Many sites see movement over months rather than days, and no one can promise a specific ranking.
Is SEO still relevant with AI search?
Yes. AI search tools often draw on the same web content and signals that traditional search uses. Clear, accurate, well-structured content helps in both.
Can I do SEO myself?
Yes, many basics are accessible, such as writing helpful content and fixing titles. Technical issues and competitive markets may call for specialist help.
What is the difference between SEO and SEM?
SEO earns unpaid listings. SEM is a broader term that is often used for paid search advertising, and sometimes includes SEO as well.
