Keyword marketing describes buying or targeting
search terms on search engines (e.g. Google, Bing) so a business’s pay‑per‑click advert is shown to users, and may cover optimising content to rank for those terms. It is not defined in legislation; it is a descriptive term used across advertising, intellectual property and consumer protection practice.
Key legal issues arise where a party bids on generic terms or a competitor’s trade mark. Selecting a trade mark as a keyword can be use in the course of trade; infringement turns on whether the advert enables the average user to see the goods/services are not those of the trade mark proprietor (CJEU Google France; Interflora v Marks & Spencer). UK risks include passing off, the Consumer Protection from Unfair Trading Regulations 2008, comparative advertising and the CAP Code (ads must be clearly identifiable and not misleading). In Ireland, similar principles apply under EU trade mark law, the European Communities (Misleading and Comparative Advertising) Regulations 2007 and the ASAI Code.
Across England & Wales, Scotland, Northern Ireland and Ireland analysis is broadly consistent. Practitioners should assess ad copy, labelling (“Ad”), keyword selection (including competitors), and search engines’ trade mark complaint procedures.
