Google quietly revised its help pages for responsive search ads to add new pinning guidelines, with the central warning targeting a common practitioner habit: loading the same or nearly identical text into a single pinned slot.
The updated guidance, reported by Search Engine Roundtable, says that repeating near-identical copy in one slot constrains the system and drags down Ad Strength. Google recommends a hybrid approach instead: pin one or two keyword-critical headlines and let the remaining assets rotate dynamically so the machine-learning system can test combinations.
Two additional points round out the revision. A keyword longer than 30 characters belongs in the description field, which allows 90, rather than in a headline slot. Each keyword should also sit whole inside one headline instead of being broken across two.
The documentation change does not include data on how sharply Ad Strength falls or how Ad Strength correlates with auction eligibility in practice. Advertisers who have applied aggressive pinning to control brand messaging should audit their RSA asset sets against these updated rules. Accounts where multiple pinned positions hold similar copy are the highest-priority targets for revision before the next performance review cycle.
