Search intent explained: the Do/Know/Go framework (SA SEO guide)
Search intent is the goal behind a search query, what the person actually wants to achieve. The four types are informational (Know), navigational (Go), commercial investigation and transactional (Do). Match your content format to the intent on the live SERP and you rank; ignore it and even a technically perfect page fails.
Ranking for a keyword is worthless if your page answers the wrong question. A Durban shopper searching “best running shoes” wants a comparison, not a checkout page, and if you serve the wrong format, Google will serve someone else. Understanding search intent is what separates traffic that converts from traffic that bounces.

TL;DR: Quick Answer
Search intent is the goal behind a search query, what the person actually wants to achieve. The four types are informational (Know), navigational (Go), commercial investigation and transactional (Do). Google reverse-engineers intent from billions of searches and rewards the pages whose content type and format match it. Study the live SERP before you write, map the intent to a funnel stage, and re-check it quarterly because intent shifts as a market matures.
Key takeaways
- Intent, not keywords alone, decides what ranks: two businesses on the same keyword see different results based on format match
- The four intents map to Do/Know/Go plus commercial investigation, and each wants a different content format
- The 3 C's (content type, content format, customer) are analysed on the live SERP before writing a single word
- Intent maps onto the funnel: informational is TOFU, commercial is MOFU, transactional is BOFU
- The SERP is the answer key: People Also Ask, shopping results and local packs reveal what Google believes satisfies the query
- Re-check intent quarterly, and watch for Reddit and TikTok results, which signal that polished copy alone will not satisfy that query
South African business owners pour time and budget into ranking for a keyword, then wonder why the traffic never converts. The reason is almost always the same: the page answers a different question to the one the searcher is actually asking. This is why two businesses targeting the same keyword can see wildly different results. The one whose page format matches what searchers expect wins, because Google reverse-engineers intent from billions of searches and rewards the pages that satisfy it.
What is search intent?
Search intent is the goal behind a search query, what the person actually wants to achieve. Google’s entire ranking system is built to satisfy it. Match your content to the right intent and you rank; ignore it and even a technically perfect page fails. Intent, not keywords alone, decides what ranks.
This is why two businesses targeting the same keyword can see wildly different results. The one whose page format matches what searchers expect wins, because Google reverse-engineers intent from billions of searches and rewards the pages that satisfy it. Getting this right is the foundation of any SEO programme that earns traffic worth having.
The four types of search intent
There are four search intent types. Informational (Know): the user wants knowledge, like “what is load-shedding”. Navigational (Go): they want a specific site, like “Takealot login”. Commercial investigation: they are comparing before buying, like “best medical aid South Africa”. Transactional (Do): they are ready to act, like “buy iPhone 15 Takealot”.
Mapped to the Do/Know/Go shorthand and expanded:
- Informational (Know). “How does POPIA affect small businesses” or “why is my website slow”. The searcher wants to learn. Serve guides, explainers and how-tos. These dominate the top of the funnel.
- Navigational (Go). “Capitec internet banking” or “Juicy Designs portfolio”. They know where they are going and just want the link. You only win these for your own brand terms.
- Commercial investigation. “Best web design agency Johannesburg” or “Shopify vs WooCommerce South Africa”. They intend to buy eventually but are weighing options. Serve comparisons, reviews and “best of” lists.
- Transactional (Do). “Hire web developer Cape Town” or “buy domain .co.za”. They are ready to act. Serve product pages, pricing and clear calls to action.
| Intent Type | Do/Know/Go | Example Query | Content Format to Serve |
|---|---|---|---|
| Informational | Know | how does POPIA affect small businesses | Guides, explainers, how-tos |
| Navigational | Go | Capitec internet banking | Fast route to a specific page (brand terms) |
| Commercial investigation | — | best web design agency Johannesburg | Comparisons, reviews, “best of” lists |
| Transactional | Do | hire web developer Cape Town | Product, pricing and contact pages |
The 3 C's of search intent
The 3 C's are content type, content format and customer. Content type is the broad category Google ranks, such as a blog post or product page. Content format is the specific structure, such as a listicle or how-to guide. Customer is the searcher’s stage and expectations. Analyse all three on the live SERP before writing.
In practice, before creating a page, you study what already ranks. If the first page for “small business website cost South Africa” is full of blog-style pricing guides, that is the content type and format Google has decided satisfies searchers. Publishing a bare service page against that grain rarely works, regardless of how good it is.
How does search intent map to the buyer journey?
Search intent maps directly onto the marketing funnel. Top of funnel (TOFU) is informational, where people discover problems. Middle of funnel (MOFU) is commercial investigation, where they compare solutions. Bottom of funnel (BOFU) is transactional, where they buy. Each stage needs content matched to its intent.
For a South African web design agency, the journey looks like this:
- TOFU (Know): “why is my website not getting leads”, a helpful blog post that earns trust.
- MOFU (Commercial): “best web design agencies in South Africa”, a comparison or case-study page that positions you among the options.
- BOFU (Do): “web design quote Johannesburg”, a contact or pricing page with a clear next step.
Most businesses over-invest in BOFU pages and starve TOFU, then wonder why no one discovers them. A complete funnel needs content at every stage, which is exactly what a content marketing programme is built to deliver.

Determine intent by analysing the live SERP for your keyword. Read the SERP features Google shows, such as People Also Ask boxes, People Also Search For, shopping results or local packs. These reveal what Google believes satisfies the query. Then map that intent to the funnel stage and build content to match.
The SERP is the answer key. If Google shows a local map pack for “web designer Pretoria”, local intent dominates and you need a location-relevant page with a Google Business Profile, the foundation of any local SEO push. If it shows shopping ads, intent is transactional. If it shows long-form guides and People Also Ask questions, intent is informational. People Also Ask boxes are a gift, they hand you the exact follow-up questions to answer on the page.
“The SERP has already told you what to build. When a client asks why their sales page won’t rank, nine times out of ten the first page is full of guides and comparisons. Google has decided what satisfies that query, and a checkout page is not it. We read the results before we write a word.”

How should content format match intent?
Match format to intent precisely. Informational queries want guides, tutorials and explainer articles. Commercial queries want comparisons, reviews and “best of” lists. Transactional queries want product pages, pricing and booking forms. Navigational queries want a clear, fast route to the destination. The format is part of the ranking signal.
Ahrefs’ featured-snippet research found paragraphs make up around 82% of featured snippets, so leading each section with a clear, direct paragraph answer increases your chance of being pulled into that prime position, whatever the underlying intent. This answer-first habit is also what gets pages quoted by AI Overviews, which run on the same core ranking, and it pairs naturally with a solid on-page SEO checklist.
How often should you re-check search intent?
Re-check the SERP for your priority keywords quarterly, because intent shifts. Google may move a query from informational to commercial as a market matures, and new SERP features appear. A page that matched intent a year ago can quietly fall out of alignment, so periodic re-analysis keeps your content matched to what searchers want now.
Watch one growing trend: Reddit threads and TikTok videos increasingly appear in South African SERPs, especially for “best” and “review” queries where searchers want authentic peer opinion. When you see community results ranking, it signals that polished marketing copy alone will not satisfy that query, you need genuine experience and specifics on the page. Folding intent re-checks into a regular content marketing strategy keeps the whole library aligned rather than letting individual posts drift.
Frequently asked questions
Can one keyword have multiple search intents?
Yes. A query like “mobile” could be informational, commercial or transactional depending on the searcher. Google handles this with mixed SERPs showing several content types. Check the live results: if the page blends guides, products and comparisons, target the dominant intent while addressing secondary intents in supporting sections.
Why does my page rank low despite good content?
The most common cause is an intent mismatch. If you wrote a sales page but the SERP rewards informational guides, Google will not rank you regardless of quality. Analyse what currently ranks, identify the intent and format Google favours, then realign your page to match it.
Is search intent more important than keyword volume?
Usually, yes. A high-volume keyword you target with the wrong intent sends traffic that bounces and never converts. A lower-volume keyword matched perfectly to intent delivers visitors ready to act. Prioritise intent alignment first, then chase volume among the keywords you can genuinely satisfy.
What are the four types of search intent?
The four types are informational (Know), where the user wants knowledge; navigational (Go), where they want a specific site; commercial investigation, where they are comparing before buying; and transactional (Do), where they are ready to act. The Do/Know/Go shorthand maps the active and learning intents, with commercial investigation sitting between them.
