What is SEO? A plain-English guide for South African business owners
SEO is how your business gets found in Google's ordinary results without paying for the spot. This guide explains how it works, what you can do yourself, and when it is worth paying for help.
What is SEO, and what does it mean for a business like yours? SEO stands for search engine optimisation: the work of making your website easy for search engines to find, understand and trust, so that it appears when people search for what you sell. It is not advertising. You don’t pay Google for the position; you earn it with a site that works properly, pages that answer real questions, and a good name on the rest of the web.
Google’s own definition is similar. Its SEO Starter Guide says that SEO is about helping search engines understand your content, and helping people find your site and decide whether to visit it. The same guide admits there are no secrets that will automatically rank a site first.
How does SEO work?
SEO works by helping your pages through the three stages Google uses to build its results: crawling (finding and downloading a page), indexing (working out what it is about and storing it) and serving (choosing which stored pages best answer each search).
Google’s in-depth guide to how Search works sets this out. Its crawlers find new pages by following links from pages they already know, and problems with your server, or a setting that blocks them, can stop them. Indexing isn’t guaranteed either: Google lists low-quality content, and settings that forbid indexing, among the common reasons a page is left out.
When someone searches, Google ranks the indexed pages on hundreds of factors, which can include the searcher’s location, language and device. So the same search for a plumber can return different businesses in Randburg and in Pretoria, and your own searches are a poor guide to where you stand. Google also says plainly that it doesn’t accept payment to crawl a site more often or to rank it higher, and that anyone who tells you otherwise is wrong.
Our guide to how Google decides where your website ranks goes into the detail.
The four parts of SEO
Most of what gets sold as SEO falls into four parts, and how much each one matters depends on what you sell and where your customers are.
| Part | What it covers | What it looks like for a business |
|---|---|---|
| Technical SEO | Whether Google can reach, read and trust your site: speed, mobile, security, nothing blocked by mistake | A site that loads quickly on a phone, runs securely on HTTPS and hides nothing important from Google |
| On-page SEO | Pages that match what your customers search for, with clear titles and headings | A page for each service, titled with what it is and where you work |
| Off-page SEO | Links and mentions from other websites | A supplier, trade body or local publication linking to your site |
| Local SEO | Your Google Business Profile and the map results | A verified, complete profile with the right category, hours and photos |
Technical SEO: a site Google can reach and read
This is the foundation. Google’s page experience guidance says that its ranking systems use Core Web Vitals, which measure loading, interactivity and visual stability. For loading, Google’s target, as at 2 October 2026, is that the largest piece of content on a page appears within 2.5 seconds of the page starting to load. Google also says it will still show the most relevant page when its page experience is poor, but where plenty of helpful pages answer the same search, a good page experience can contribute to success.
Big City Life, a photographer’s site, came to us very slow. We reduced it from roughly 85GB to about 4.5GB and moved it onto our hosting, with security added.
Security belongs here too. Google’s spam policies cover content that hackers place on a site without permission, and sites that break the policies can rank lower or disappear from results. Xscape4u was referred to us after a hack of that kind: its site was being injected with links to offshore casino sites. We rebuilt the platform clean.
Every site we build on our Business or Professional package starts with this groundwork: Rank Math, LiteSpeed and Wordfence configured (the tools we use for SEO settings, speed and security), and Google Analytics 4 and Search Console set up. If your site runs on WordPress, our checklist of what your site should already be doing for SEO shows what to look for.
On-page SEO: pages that answer the search
This is the part most people picture. Google’s Search Essentials advise using the words people would use to look for your content, in prominent places such as the page title and main heading. The Starter Guide goes further: content that people find compelling and useful is likely to affect your presence in search more than anything else it recommends.
In practice, that means a page for each service you sell, written the way your customers talk about it, answering what they ask before they buy. Finding those words is keyword research, which our guide to keywords and backlinks covers. Online stores have their own version of this work: getting product and category pages found.
Off-page SEO: other sites vouching for you
Links from other websites help Google find your pages, and the Starter Guide says PageRank, the Google algorithm built on links, is one of its many ranking signals. The links that help are earned: a supplier, a trade body or a local publication linking to you because your page is worth pointing to. Buying them breaks Google’s spam policies, which list buying or selling links for ranking purposes as link spam. Our article on which backlinks help, and why buying them backfires explains the difference.
Local SEO: getting onto the map
When someone searches for a business near them, Google shows local results in Search and on Google Maps. Its guide to local ranking says that these results are mainly based on relevance (how well your Business Profile matches the search), distance (how far you are from the person searching) and prominence (how well known your business is, including how many websites link to you and how many reviews you have). It also says there is no way to pay for a better local ranking.
What you control is the profile itself: verified, complete and accurate, with photos and replies to your reviews. Google says a Business Profile is free (as at 2 October 2026), and setting one up is part of our Business package. Our Google Business Profile guide takes you from set-up to your first enquiry, and local SEO for South African businesses covers what moves you up the map results.
What is SEO in digital marketing?
In digital marketing, SEO is the unpaid side of search. Google Ads rents you a place among the ads for as long as you pay. SEO earns a place in the ordinary results, which Google says it never sells. Both reach people at the moment they are looking, which social media and email usually don’t.
Google keeps the two apart. Its page Do you need an SEO? says that advertising with Google has no effect on your site’s presence in its search results, and that appearing in the organic results costs nothing.
| What differs | SEO | Google Ads |
|---|---|---|
| Where you appear | The ordinary results, earned | Among the ads, paid for |
| What a visitor costs | Nothing per click | Paid from your ad spend |
| How quickly it works | Slower to build | Visitors as soon as the ads run, until the spending stops |
The two can run side by side, as they do for Thrive Raw Food For Dogs, an online store we built in 2025: we still host it, and look after its analytics, SEO and Google Ads.
How long does SEO take to work?
Some changes show up in Google within hours; others take several months. Google’s SEO Starter Guide advises waiting a few weeks before judging whether a change has worked, and adjusting if it hasn’t. Plan in months rather than weeks, and measure progress in Search Console rather than by searching for yourself.
Search Console, Google’s free reporting tool (as at 2 October 2026), shows how your site does in searches by real people, not the one search you happen to make from your office. Our guide to the Search Console reports worth checking each month shows where to look.
Not every change makes a noticeable difference, as the Starter Guide itself says, and nobody can promise a date: Google doesn’t guarantee that it will crawl, index or show any page, even one that follows all its rules.
Does SEO still matter now that Google answers with AI?
Yes. To appear as a link in Google’s AI Overviews or AI Mode, a page must first be indexed and eligible to show in ordinary search with a snippet. Google says the usual SEO best practices apply to its AI features, with no extra requirements, and no special files or markup to add.
That is from Google’s page on AI features and your website. The same page says AI Overviews appear only when Google’s systems decide they add something to classic search, so they often don’t show. For this very search, one did: when we checked Google’s South African results for “what is seo” on 27 September 2026, an AI Overview sat above the first ordinary result.
Assistants such as ChatGPT and Gemini are another route to the same customers. Our guide to getting your business cited by ChatGPT, Gemini and Google’s AI Overviews covers them too. Our audit checks that AI search tools can reach your site, and how your business appears in AI answers.
SEO for beginners: what you can do yourself this month
Much of the groundwork needs no paid tools, only time. These five steps follow Google’s own guidance:
- Set up Google Search Console.
It shows which searches your site appears for and how often people click, and alerts you to problems Google finds. - Check that Google has found your site.
Search Google for site: followed by your domain, for example site:yourbusiness.co.za. If your pages appear, they are in Google’s index. If nothing comes up, why your website isn’t showing on Google lists the usual reasons, in order. - Give each important page a clear title and description.
Google builds the headline of your result from a few sources, including the page title and your headings. Google’s SEO Starter Guide recommends a title that is unique to the page, concise and descriptive, which can include your business name and location, and Google’s guidance on title links warns against vague ones such as “Home”. The meta description is the short summary Google sometimes shows beneath it. - Write the pages your customers are looking for.
One page for each service you sell, answering what people ask before they buy: what it involves, what it costs, how long it takes and which areas you cover. Our SEO plan for a small business shows what to do first, and what can wait. - Claim and complete your Google Business Profile.
Verify it, choose the right category, keep your hours and contact details accurate, add photos and reply to reviews. How to add your business to Google walks through it step by step.
Just as useful is what you can skip. According to the Starter Guide, Google doesn’t use the keywords meta tag, keywords in your domain name have hardly any effect, and there is no magic word count: length alone doesn’t matter for ranking. A domain ending such as .co.za matters only if you are targeting customers in one country, and even then Google says it is usually a low-impact signal.
Do you need an SEO company?
Not always. Google says a small local business can probably do much of its SEO itself. Paying makes sense when you’re short of time, when your site has technical problems you can’t fix, or when you’re about to redesign or launch a site, which Google calls a great time to hire.
Both points come from Google’s page Do you need an SEO?. The same page is blunt about what to avoid:
- No one can guarantee a first-place ranking on Google. Walk away from anyone who promises one, or who claims a special relationship with Google.
- Be wary of SEO companies that email you out of the blue.
- You should never have to link to your SEO company from your own site.
- An audit should give realistic estimates of the improvement and of the work involved. Give the auditor read-only access to your Search Console, nothing more.
- Advice on AI search, sometimes sold as AEO or GEO, should match Google’s own guidance on its AI features.
- You are responsible for what the companies you hire do. If one creates deceptive content on your behalf, your site could be removed from Google entirely.
Our guide to choosing an SEO company turns this into questions to ask, and what a proper SEO audit covers shows what a good audit should include.
What SEO costs with us
We are a Johannesburg studio that has built and run websites for South African businesses since 2001, and we publish our SEO prices. All are in South African rand, incl. VAT.
- SEO audit: R6,500. A technical, on-page, local and competitor audit of your site, reading your Search Console data through read-only access and ending in a prioritised list of fixes. If you start monthly SEO with us within 30 days, half of the R6,500 is credited against the first month. Making the fixes is not part of the audit. See a sample audit report (a fictional example).
- Monthly SEO: from R7,500 a month, with a six-month minimum. It covers content, on-page work, local SEO, winning links from other sites and a monthly report that says what went live, what is working and what to do next. Google Ads, paid social and ad spend are not included.
- A new website: our Business package, R15,000, includes the groundwork described above and sets up your Google Business Profile. Ongoing SEO is not part of it.

Frequently asked questions
Can you do SEO yourself?
Yes, much of it. Google says a small local business can probably do much of the work itself, starting with its free SEO Starter Guide. You are usually the best person to write about your own services and keep your Business Profile current. Technical problems with speed, security or indexing are where outside help earns its keep.
Can I learn SEO for free?
Yes. Google’s SEO Starter Guide and the rest of its Search Central documentation are free to read, and Search Console is a free service. They come from the company whose results you want to appear in, which makes them the natural place to start. What SEO really costs is time, month after month.
What is an SEO example?
Say a plumber in Randburg changes its home page title from “Home” to “Plumber in Randburg: geyser repairs and call-outs”, adds a page for each service, verifies its Google Business Profile and asks every customer for a review after the job. Each step is SEO: it helps Google understand what the business does and where, and helps searchers choose it.
How do I SEO my site?
Start with five steps: set up Google Search Console, check that Google has found your site, give each important page a clear title and description, write a page for each service you sell, and claim your Google Business Profile. Then fix what Search Console reports, and check progress monthly. Deeper technical problems are what an SEO audit is for.
