Your SEO Is Working. Your Traffic Is Still Dropping. Here Is Why.
What Google's AI Overviews mean for South African businesses, and the three concrete things you can do about it right now.
Quick Answer:
Google’s AI Overviews now answer many search queries directly on the results page, reducing the number of users who click through to websites. South Africa was included in the global AI Mode rollout in August 2025. Businesses with strong SEO are experiencing traffic declines not because their rankings have dropped, but because AI is absorbing the click before it reaches them. The response is a shift toward Generative Engine Optimisation (GEO): structuring your content to be cited by AI, not just ranked by it.
The Uncomfortable Conversation Most Marketing Agencies Are Not Having
If your website traffic has been declining over the last 12 months despite no obvious drop in your search rankings, you are not imagining things. And it is not your agency’s fault, at least not in the way you might think.
Something fundamental has changed about how Google works. The change has been gradual enough that many businesses have not connected the dots yet, and most marketing agencies are either not prioritising the conversation or do not yet have a clear answer to give.
This article is that conversation.
We are going to explain exactly what is happening, why South African businesses are now directly in the path of this change, and what you can do to protect your visibility and lead flow. All claims in this article are sourced. Where we cite data, we link to the original research so you can verify it yourself.
What Is Actually Happening to Search
Since May 2024, Google has been rolling out a feature called AI Overviews. When a user types a query into Google, instead of seeing ten blue links, they increasingly see an AI-generated summary at the top of the page that answers their question directly, without them needing to click on any website. According to data compiled from Semrush’s analysis of over 10 million keywords, AI Overviews appeared in just 6.49% of queries in January 2025, but by July 2025 that figure had peaked at nearly 25%, before settling back to around 16% as Google refined its rollout strategy.
The impact on click-through rates has been severe and well-documented. A September 2025 study by Seer Interactive, which analysed 3,119 search queries across 42 organisations tracking over 25 million organic impressions, found that organic click-through rates plummeted from 1.76% to 0.61% for queries where an AI Overview was present. That is a 61% decline. Paid search fared even worse, with click-through rates falling 68% for the same query set.
The result is what researchers are now calling the Great Decoupling. Reporting from The Digital Bloom, drawing on data from multiple industry studies, describes a pattern where search engine usage continues to rise while clicks to websites decline dramatically. In plain terms: more people are searching than ever, but fewer of those searches are reaching your website.
“60% of Google searches now end without any click to a website. Your rankings may be exactly where they were. Your traffic may not be.”

This Is Not a Distant Problem for South African Businesses
Some business owners in South Africa may have assumed that AI Overviews were a US-centric phenomenon that would take years to arrive locally. That assumption is no longer accurate.
On 21 August 2025, Google officially launched AI Mode in Search for users in South Africa, Kenya, and Nigeria, making South Africa one of the first African markets to receive the feature. Powered by Google’s Gemini 2.5 model, AI Mode enables users to ask complex, multi-part questions and receive AI-generated responses directly within the search interface.
Then, in March 2026, Google expanded AI Overviews and AI Mode to support 13 African languages, including Afrikaans, isiZulu, Sesotho, and Setswana. According to IT News Africa, the expansion was driven by strong and growing search usage across Sub-Saharan Africa, with the languages selected specifically to reach large, active communities across South Africa, Nigeria, Kenya, Ethiopia, and beyond.
This expansion matters for South African businesses in practical terms. Kabelo Makwane, Country Director for Google South Africa, stated in the company’s 2025 Year in Search report that AI is becoming deeply integrated into South Africans’ daily information journeys. The shift in how South Africans search is no longer theoretical. It is already underway.
For a South African service business that has invested in SEO and content marketing, the implications are direct. The blog posts ranking on page one of Google for your target queries may now be returning an AI-generated summary that answers the searcher’s question without them ever visiting your site.
What this means for local search: The good news, for now, is that local and transactional searches are less affected. Research from Ahrefs found that only 7.9% of local searches trigger an AI Overview. Searches with clear commercial intent, such as ‘fractional CMO Johannesburg‘ or ‘digital marketing agency Cape Town‘, are less likely to be intercepted by AI summaries than informational queries like ‘what is a fractional CMO‘ or ‘how does digital marketing work‘. However, this is expected to change as Google expands AI Overviews further into commercial query territory.
What Changes About How Search Works
To understand what to do next, it helps to understand exactly what has changed about how search works. The table below illustrates the shift in plain terms.
The Old World of Search (Pre-2024) | The New World of Search (2025 Onwards) |
User types a query. Google returns 10 blue links. User clicks one. | User types a query. Google generates an AI answer at the top. User reads it. Does not click. |
Rankings = visibility. Page 1 = traffic. | Ranking on page 1 still matters, but no longer guarantees a click. |
SEO success measured by rankings and traffic. | SEO success increasingly measured by citations, brand visibility, and share of voice. |
Content strategy built around keywords. | Content strategy built around answering questions authoritatively and being cited as a trusted source. |
Your website is the destination. | AI is increasingly the destination. Your content is the raw material it draws from. |
The core insight is this: Google has begun transitioning from a directory that sends users to websites into an answer engine that satisfies queries directly. Gartner has predicted, that traditional search volume will drop 25% this year as users shift to AI-powered answer engines. Meanwhile, AI-referred sessions jumped 527% year-over-year in the first five months of 2025, according to Previsible’s 2025 AI Traffic Report. The traffic is not disappearing. It is moving channels.
The question for South African businesses is not whether this shift is happening. It is happening. The question is: when AI answers a query in your area of expertise, is your brand being cited or ignored?

There Is a Clear Upside, If You Move Quickly
This is not a purely negative story. For South African businesses willing to adapt their content strategy now, the opportunity is significant, because most local competitors have not started yet.
The Seer Interactive research found a striking pattern: brands cited within AI Overviews earned 35% more organic clicks and 91% more paid clicks compared to brands that appeared on the same results page but were not cited. One AI citation, in other words, can deliver more qualified traffic than a standard page-one ranking for the same query.
There is also evidence that users who arrive via AI referrals are more engaged. Adobe’s 2025 Analytics Report found that AI-referred visitors show 23% lower bounce rates compared to traditional organic traffic visitors. The implication is that when AI cites your content, it has already pre-qualified the user. They arrive knowing what you do and why it might be relevant to them.
For a South African service business where qualified leads matter far more than raw traffic volume, that dynamic is worth paying close attention to.
“Brands cited in AI Overviews earn 35% more organic clicks and 91% more paid clicks than those that are not cited, even when they appear on the same results page.”
What to Do About It: A Plain-English Introduction to GEO
The practice of optimising your content to be cited by AI systems, rather than just ranked by traditional search algorithms, is called Generative Engine Optimisation, or GEO. It is the most important shift in digital marketing strategy since mobile-first indexing, and it is still early enough that businesses that move now will have a genuine advantage over those that wait.
GEO does not replace SEO. Strong domain authority, quality backlinks, and technical site health still matter significantly, and they remain foundational inputs to how AI systems decide which sources to trust. What GEO adds is a specific set of content practices that make your material easier for AI systems to extract, trust, and cite.
Below are the eight highest-impact actions available to a South African business today. These are drawn from the latest research on what actually drives AI citation, including academic work from Princeton, Georgia Tech, and IIT Delhi, as well as from practitioner studies by Seer Interactive, Profound, and Search Engine Land.
Action | What to Do | Why It Matters |
Direct answers first | Open every article or service page with a 40–60 word answer to the main question. Expand below. | AI retrieval systems prioritise the opening content. If your answer is buried three paragraphs down, it may be ignored. |
Use question-based headings | Write H2s and H3s as actual questions your audience asks. e.g. ‘What does a fractional CMO cost in South Africa?’ | AI systems pattern-match headers to queries. A heading that mirrors the query is more likely to be cited. |
Add statistics frequently | Include a data point or cited statistic every 150–200 words throughout the content. | Research shows statistics-rich content earns 30–40% higher visibility in AI-generated responses. |
Cite authoritative sources | Link to credible, named sources for every claim. Government data, academic research, industry reports. | AI engines use citation patterns as a trust signal. Content that cites others is more likely to be cited itself. |
Build multi-platform presence | Publish on LinkedIn, contribute to industry conversations, earn mentions on third-party sites. | Reddit, LinkedIn, and YouTube are among the most cited sources by leading AI platforms. Presence there feeds visibility. |
Update content regularly | Add a visible ‘Last Updated’ date and refresh statistics and examples at least quarterly. | AI systems favour fresh content for time-sensitive queries. Stale content loses citation share over time. |
Structured data / schema markup | Implement FAQ schema, Article schema, and Organisation schema on your key pages. | Schema markup helps AI crawlers understand and extract your content more reliably. |
Focus on E-E-A-T signals | Show author credentials, link to your About page, include client outcomes, reference your experience explicitly. | Experience, Expertise, Authoritativeness, and Trustworthiness remain the core trust signals for both Google and AI systems. |

What to Measure Now: Your Metrics Need to Change Too
If you are still measuring your digital marketing performance primarily through organic traffic and keyword rankings, you are measuring the old world while operating in the new one.
The metrics that tell you whether your content strategy is working in an AI-driven search environment are different. Here is what to track alongside your traditional SEO indicators:
- AI citation frequency. How often is your brand or content being cited in AI-generated answers on Google, ChatGPT, and Perplexity for your priority queries? Tools like Profound and Semrush’s AI visibility features are beginning to track this.
- Share of voice in AI answers. When someone asks an AI system about your category, your services, or a problem you solve, do you appear in the response? Regularly testing this manually with your target queries gives you a baseline.
- AI-referred traffic in GA4. Google Analytics 4 now allows you to segment traffic by referral source, including from AI platforms. Track the volume and quality of visits arriving from ChatGPT, Perplexity, and other AI tools.
- Lead quality by channel. As AI referrals grow, track whether the leads arriving from AI-cited content convert differently from traditional organic traffic. The early evidence suggests they convert better.
The broader point, as Seer Interactive’s research confirms, is that success metrics are shifting from clicks and traffic to visibility and share of voice. If your current marketing reporting does not include any measure of AI visibility, that is the first gap to close.
What Not to Do
Given the scale of this shift, a few common overcorrections are worth naming directly.
Do not abandon SEO
Traditional SEO and GEO are complementary, not competing. Research from Ahrefs found that 76.1% of URLs cited in AI Overviews also rank in the top ten of Google search results. Strong domain authority, technical SEO health, and quality backlinks all feed directly into whether AI systems trust your content enough to cite it. The foundation remains the same.
Do not flood your site with AI-generated content
Google has explicitly flagged thin, AI-generated content as a spam risk that can result in demotion across both traditional search results and AI citations. The businesses gaining citation share are those publishing fewer, better pieces of content that demonstrate genuine expertise and are based on original thinking or data.
Do not wait for certainty
The landscape is evolving fast. Publishers surveyed by the Reuters Institute expect their search traffic to decline by 43% on average over the next three years. Waiting for the picture to stabilise before acting means ceding ground to competitors who are adapting now. The businesses that began building for featured snippets in 2015 were the same ones best positioned when AI Overviews arrived. The same pattern will repeat.
The Strategic Takeaway for SA Business Owners
The shift from search-engine-driven to AI-driven discovery is not a future event. In South Africa, it is already underway. AI Mode is live. Thirteen local languages are supported. The behaviour of South African searchers is changing alongside the tool.
Your existing SEO investment is not wasted. But it needs to be supplemented with a content strategy built for the new environment: content that answers questions directly, demonstrates genuine expertise, earns citations from other credible sources, and is structured in a way that AI systems can extract and trust.
That is not as complex as it might sound. It does, however, require a deliberate strategy rather than the default approach of writing for keywords and waiting for rankings to translate into traffic.
If your current digital marketing plan has not addressed this shift yet, that is the most important conversation to have with your marketing advisor or agency right now.
