In South Africa, Google Ads keyword battles turn on confusion and registration
A fresh South African commentary this week has put the ClearVu line back into focus. The underlying Supreme Court of Appeal judgment dates from 2016, but the practical signal still matters now: buying a competitor’s trade mark as a hidden Google Ads keyword is not automatically unlawful. The harder question is whether the advertisement that users actually see creates confusion about source, affiliation, endorsement or commercial connection.
The more important lesson sits one layer deeper. In ClearVu, the claimant was not advancing a straightforward registered-trade-mark infringement case. It had to lean heavily on passing off and unlawful competition. Under South Africa’s Trade Marks Act and CIPC’s own public guidance, statutory infringement proceedings depend on registration. That makes registration more than an administrative tidy-up. In keyword disputes, it often decides whether the claimant arrives with a sharper statutory cause of action or with a far heavier evidentiary burden.
This week’s signal is a playbook, not a new doctrine
The timeline matters. South Africa did not suddenly issue a brand-new keyword-advertising rule this week. The legal anchor remains the 2016 ClearVu appeal decision. What changed this week is that practitioners have restated the position in a way that speaks directly to today’s search-ad market, where aggressive bidding on rival brand terms has become routine and many businesses still overread what that means legally.
That distinction is practical, not academic. A rights holder who fixates only on the fact that a rival bought its mark as a keyword can lose the case before it really starts. The evidence that usually matters is wider: the ad headline, description, display URL, landing page, screenshots of the search-results page, the date and location of the search, and the overall presentation to users. Courts are not really being asked whether the back-end bidding move felt unfair in the abstract. They are being asked whether the front-end presentation was misleading in the real world.
Hidden keywords are rarely the whole problem; ad copy and landing pages do the legal work
This is where South African doctrine and Google’s own policy sit surprisingly close to one another. Google’s published trade mark policy generally does not restrict the use of trade marks as keywords, while reserving the right to restrict confusing or misleading use of trade marks in the ad itself after complaint review. South African case law has taken a similarly focused view. The hidden keyword on its own is usually not the complete answer. What counts is how the ad appears and what impression it leaves.
That is why the danger points in these disputes often sit in the creative layer, not in the media buy alone. If the advertiser clearly identifies its own brand, avoids suggestive affiliation language and keeps the landing page from implying an official, authorised or source-linked relationship, a confusion case becomes harder to sustain. The risk rises quickly where the rival mark is inserted into the ad text, where comparative wording is left deliberately slippery, or where the landing page trades too heavily on the idea that the user has reached the trade mark owner or an endorsed alternative.
Why registration changes leverage so dramatically
This is the part many businesses still underestimate. South Africa’s Trade Marks Act makes registration the gateway to statutory infringement proceedings. Without registration, a claimant is not left remediless, but it is pushed toward common-law claims that require a more fact-heavy showing of reputation, misrepresentation, confusion and damage. In keyword advertising cases, defendants are often well positioned to attack exactly those elements by arguing that the ad never used the mark visibly, that users could distinguish the advertiser, or that the search-results context itself signalled competitive advertising.
Once the mark is registered, the conversation changes. The claimant can organise its case within the statutory infringement framework, and where a registered mark is also well known in South Africa, the statute may open stronger arguments around unfair advantage or detriment to distinctiveness or repute. Registration does not eliminate the need to prove the right facts, and it does not make every keyword bid unlawful. But it changes litigation posture, demand-letter pressure and settlement leverage in a very real way. In digital click wars, registration is often the difference between attacking from a position of legal structure and trying to improvise from common-law vulnerability.
What brand owners and advertisers should tighten now
For brand owners, the first move is not to demand that platforms ban all bidding on branded terms. The more durable move is to register core marks and high-value search terms promptly, then build a disciplined monitoring and evidence-preservation routine around search results. When problematic ads appear, one screenshot is rarely enough. Save the query term, date, time, geography, device view, ad ranking, ad variations and landing-page path. A keyword case is often won or lost on whether the route to confusion can be shown cleanly rather than asserted angrily.
For advertisers, ClearVu should not be read as a blanket permission slip. A safer operating model is to separate keyword ambition from ad-copy restraint. Bid strategy may be aggressive, but the ad itself should identify the advertiser clearly, comparative claims should be supportable, and any references to alternatives, compatibility or substitution should be handled with unusual care. Many disputes do not begin in the auction. They begin when a campaign chasing click-through rate adds one line too many and nudges the consumer toward the wrong conclusion about origin. South Africa’s position leaves room for hard competition, but not for competition that wins by bending source perception.
