Why does Google Search have such tight character limits?

Google Search ads compete for limited SERP space. 30-character headlines and 90-character descriptions ensure ads stay readable on mobile and desktop. The constraint forces sharper copy.

How many ad variants should I test?

Google's Responsive Search Ads use 3-15 headlines and 2-4 descriptions per ad. Meta's Dynamic Creative tests up to 10 variants. Generate 5-10 variants and let the platform optimize.

Will my ads pass platform policy?

These tools generate copy that follows general best practices, but every platform has specific policies (no superlatives without proof on Meta, no health claims on Google for unverified products, etc.). Always review against current platform policies before launching.
