SEO helps your website appear higher in Google search results. This guide explains what it is, how it works, and why it matters—in plain English.
SEO (Search Engine Optimization) is the process of improving your website so it ranks higher in search engine results like Google.
When someone searches "best coffee shop in Singapore," the results they see aren't random. Google's algorithm decides which websites are most relevant and trustworthy. SEO is how you influence that decision.
To understand SEO, you first need to understand how Google finds and ranks websites.
Google sends out "bots" (automated programs) to discover web pages. These bots follow links from page to page, building a map of the internet. If Google can't find your pages, they won't appear in search results.
Once discovered, Google analyzes each page's content and stores it in a massive database (the "index"). Google looks at the text, images, and structure to understand what each page is about.
When someone searches, Google looks through its index and decides which pages best answer the query. It considers hundreds of factors: relevance, authority, user experience, and more. This is where SEO comes in—optimizing these factors.
SEO isn't one thing—it's a combination of technical, content, and authority factors.
The foundation. Making sure search engines can crawl and index your site properly.
Optimizing individual pages so Google understands what they're about.
Building authority through external signals—mainly links from other websites.
Unlike ads that stop when you stop paying, SEO builds lasting organic traffic. A page that ranks well continues bringing visitors for months or years.
People searching for what you offer are already interested. "SEO agency Singapore" is someone actively looking for your service—not a random ad viewer.
SEO requires upfront investment, but cost-per-acquisition typically decreases over time. Paid ads charge you for every click; organic traffic is "free" once you rank.
People trust organic results more than ads. Ranking on page one signals that Google considers you a relevant, trustworthy source.
Most successful businesses use both. SEO for long-term foundation, paid ads for immediate needs. Read our full comparison →
