Keyword research means finding out the actual words and phrases your potential customers type into Google when they’re looking for what you sell — then using those words in your website and blog content so Google can match your pages to those searches. For most South African small businesses, it costs nothing but time.
What Is Keyword Research, Really?
Strip away the jargon and keyword research is simply this: working out what your customers actually search for, in their own words, rather than guessing based on how you describe your business internally. A dog groomer might think of herself as offering “canine aesthetic services” — her customers are searching “dog groomer near me” or “mobile dog wash Durban”. The gap between those two phrases is, in a nutshell, why keyword research matters.
Done properly, it tells you which topics are worth a blog post, which words belong in your page titles, and which questions your website should be answering that it currently isn’t.
Why Should a Small Business Bother With It?
If you’ve read our piece on local SEO and Google Business Profile, you’ll know that showing up in local search results depends partly on using the right words in the right places. Keyword research is how you find out what those right words actually are, instead of relying on instinct. It also stops you wasting time writing content nobody is searching for — a common trap for small businesses with limited hours to spend on marketing.
Which Free Tools Can You Actually Use?
You don’t need an expensive subscription to get started. Here are the tools we recommend first:
| Tool | Cost | Best for |
|---|---|---|
| Google Keyword Planner | Free (needs a free Google Ads account — no need to run paid ads) | Search volume ranges and related keyword ideas |
| Google Search Console | Free | Seeing the exact searches already bringing people to your site |
| Google Trends | Free | Checking whether interest in a topic is rising, falling or seasonal |
| Google’s autocomplete & “People also ask” | Free | Quick, real-world phrasing and question ideas straight from the search results page |
Google Keyword Planner is technically built for advertisers, but you can create a free Google Ads account, skip setting up a campaign, and still use the tool to research keywords at no cost. Paid tools like Ahrefs, Semrush or Ubersuggest offer more detail and usually have a limited free trial, but they’re an upgrade for later — not where to start.
How Do You Actually Do Keyword Research? A Simple Process
- List your topics, not your products. Think about the problems you solve and the questions customers ask you in person or over WhatsApp — these are often better starting points than your service names.
- Feed those topics into Google Keyword Planner or Google Trends to see related terms and roughly how much search interest they get.
- Check Google’s autocomplete and “People also ask” for the exact phrasing real people use.
- Look at your own Google Search Console data for queries you’re already getting some visibility for but aren’t yet ranking well on — these are often the quickest wins.
- Group similar keywords together and match each group to one page or blog post, rather than trying to target everything on your homepage.
What’s the Difference Between Short-Tail and Long-Tail Keywords?
A short-tail keyword is broad and highly competitive — “accountant Cape Town”, for example. A long-tail keyword is longer and more specific — “accountant for freelancers Cape Town” or “how much does a small business accountant cost in South Africa”. Long-tail keywords usually have lower search volume, but the people searching them tend to know exactly what they want, so they’re often easier to rank for and more likely to convert into an enquiry. For a small business without a big marketing budget, long-tail keywords are usually the better place to focus first.
Common Keyword Research Mistakes to Avoid
- Guessing keywords based on industry jargon instead of how customers actually talk
- Targeting one highly competitive keyword on every page instead of a spread of more specific ones
- Never checking back in Google Search Console to see what’s actually working
- Stuffing keywords unnaturally into a page instead of writing for a human first
Key Takeaways
- Keyword research means finding the exact words your customers use to search for what you offer
- Google Keyword Planner, Google Search Console and Google Trends are all free and enough to get started
- Long-tail keywords are usually a better starting point than broad, competitive terms
- If you’re already batching your content planning, add a keyword research step before you decide what to write about next
Keyword research isn’t a once-off task — it’s worth revisiting every few months, especially as how people search keeps changing. But even a single afternoon spent on the basics above will give most small businesses months’ worth of better-informed content ideas.
