What is SEO and how does it work?

By Jo van Vuuren — Fractional CMO

SEO stands for search engine optimisation. “Search engine” is Google, Bing and the like; “optimisation” just means making something work better. Put simply, SEO is everything you do to help search engines understand what your website is about, trust that it is worth showing people, and put it in front of the right searchers, without you paying for every click.

What does SEO actually mean?

When someone types a question into Google (“plumber near me”, “best accountant for a small charity”, “how to fix a leaking tap”), Google tries to work out which pages will answer that question best, and lists them in order. SEO is the work you do to make sure your page is one Google trusts enough to show, and near the top of that list.

It is not a trick or a technical dark art. Most of it is simply making your website genuinely useful and easy to find, for people, and for the search engines reading it.

Why does SEO matter for a small business?

Think about how you search for things yourself. If you need a plumber, you probably do not reach for the phone book; you search online and pick from the first few results. Your customers do exactly the same when they are looking for what you sell. If your website does not appear, it does not matter how good your business is: people simply will not know you exist.

SEO matters because it is one of the few marketing channels that keeps working long after the effort goes in. An advert stops working the day you stop paying for it. A page that ranks well on Google can keep bringing in customers for years.

What are the three big parts of SEO?

• Relevant content: pages that clearly answer the questions your customers are actually typing, in their words, not yours.
• A sound website: one that loads quickly, works on a phone, and is easy for people and search engines to navigate.
• Trust: other websites linking to you or mentioning your business, which signals to Google that real people vouch for you.

All three need to work together. Well-written content on a slow, broken website will not rank. A fast, well-built website with thin or generic content will not rank either. And even great content on a great website struggles to break through with no one else pointing to it.

Is SEO a quick fix, or a long game?

SEO is a long game, and anyone who promises overnight results is not being straight with you. It typically takes months of steady work before you see a meaningful shift, because Google needs time to notice your site, crawl it, and build up trust in it. That is the trade-off: slower to build than a paid advert, but far more durable once it is working.

Where should you start?

Write a short list of the exact questions and phrases your customers use when they are looking for a business like yours. Then check whether your website actually answers those questions clearly, loads quickly, and works well on a phone. Fix the obvious gaps first: that alone puts most small businesses ahead of competitors who have never given SEO a thought.
