Back to glossary

SEO (Search Engine Optimization) is the practice of improving a website so it ranks higher in search engine results for queries relevant to its content. It encompasses technical optimization, content creation, on-page elements, and external signals like backlinks. The goal is to earn organic (unpaid) traffic from search engines.

Why it matters

Organic search is one of the largest channels for most websites. Ranking well for relevant queries drives consistent, free traffic.

Example

A shoe retailer optimizes product pages with descriptive titles, structured data, and internal links, resulting in higher rankings for "running shoes" and more organic traffic.

Common misconceptions

  • SEO is a one-time task rather than an ongoing process.
  • SEO guarantees specific ranking positions.
