What Is SEO, Really? A Plain-English Guide for Business Owners

SEO stands for Search Engine Optimisation. It means doing everything you can to make it easy for search engines — easier to just think “Google” — to understand your website and show it to the right people when they search. That’s it. That’s the whole concept.

I know it can sound overwhelming, but at its core, SEO is about helping Google make better decisions about your website.

How does Google actually decide what to show?

Every time someone types something into Google, the search engine makes a decision in a fraction of a second. Out of billions of web pages, it picks the ones it thinks are most relevant, most trustworthy, and most useful — and ranks them in order.

That decision is based on hundreds of factors, but the main ones boil down to this: how relevant is your content to what the person searched? How trustworthy does your website appear? How fast does it load? Does it work properly on a phone? Do other reputable websites link to yours? Are your business details consistent across the internet?

Google is weighing all of that — and more — in microseconds. SEO is about making sure the things within your control are working in your favour so you score higher in that calculation and appear higher on the page.

You already know what SEO looks like

Here’s the thing — you’ve seen SEO in action hundreds of times. You just didn’t call it that.

Open Google and search for something. The results page you’re looking at is the end product of SEO. At the top, you’ll usually see sponsored results — those are paid ads. Businesses pay Google to appear there. Below that, you might see a map section with three local businesses — that’s called the Local Pack, and it’s powered by Google Business Profiles. Then you’ve got the organic results — the regular listings that earned their spot through relevance, quality, and trust signals. Not by paying for it.

If you’ve ever searched for a product and seen a row of shopping results with images and prices, that’s Google Merchant Centre — a separate system for online stores.

The point is, different types of searches trigger different types of results. And where your business shows up — or whether it shows up at all — depends on how well your online presence is set up.

What can you actually do about it?

SEO breaks into three broad areas:

On-page SEO is the stuff on your actual website — your page titles, headings, the words on each page, image descriptions. It’s about making sure each page clearly tells Google what it’s about. This is the most accessible part for DIY.

Technical SEO is the behind-the-scenes work — site speed, mobile responsiveness, security (that padlock in your browser), and structured data that helps Google understand your content. You can’t see most of this by looking at the website, but Google can.

Off-page SEO is what happens elsewhere on the internet — other websites linking to yours, your Google reviews, directory listings, and how consistently your business information appears across the web. This is the hardest to control because it depends on other people.

You don’t need to master all three. Knowing they exist and focusing on the basics in each area puts you ahead of most small businesses — because the truth is, 58% of businesses still don’t have any local SEO strategy at all.

The honest version

SEO isn’t a one-off task you do and forget about. It’s ongoing. Google’s algorithm changes constantly, and your competitors aren’t standing still either. Expect 3–6 months before you see meaningful results from any changes — that’s normal, not a sign that something’s broken.

Be wary of anyone promising guaranteed page 1 rankings. Nobody can guarantee that. What good SEO does is put you in the strongest possible position to rank well and improve steadily over time.

And if you’re spending hours trying to figure this out when you could be making money doing what your business actually does — that’s probably a sign it’s time to have a quick chat with someone who can point you in the right direction. No sales pitch, just honest advice about where to focus.
