Search Engine Optimisation (SEO) is the practice of improving your website so it ranks higher in search engine results. When someone searches for a product or service you offer, SEO is what determines whether your site appears on page one — or page ten.
For businesses, this matters because organic search is one of the highest-intent traffic sources available. A visitor who finds you by searching a specific query is already looking for what you sell. That means lower acquisition costs and higher close rates compared to interruption-based advertising.
SEO works across three layers: technical health (site speed, crawlability, structured data), on-page relevance (content that matches search intent), and authority (links from credible external sites). Neglecting any one layer limits results in the other two.
The timeline for SEO results is typically 3–9 months, which is why it rewards businesses that start early. Once you build authority in your niche, compounding returns kick in — pages that rank today continue driving traffic months or years later with minimal ongoing cost.
