SEO, or Search Engine Optimization, is the set of techniques that improve a website’s visibility in organic search engine results. It covers three broad areas: technical SEO (site speed, crawlability, mobile-friendliness, clean URLs), on-page SEO (titles, headings, content, internal links, meta descriptions) and off-page SEO (backlinks, reviews, authority signals).
For small businesses, the highest-impact tactics are local SEO, keyword-aligned content that answers real questions, and a technically sound, fast website. SEO is a long-term investment: results build over months, not days, but organic traffic compounds and keeps paying after the work is done.
