What it does

Add a short non-clickable selling-point snippet (callout) that appears beneath a Google Ads ad — short trust-builder phrases like "Free Shipping", "24/7 Support", "Money-Back Guarantee", or "No Setup Fees". Callouts reinforce value props without taking up headline space.

                ALSO KNOWN AS: callout, callout extension, selling point, trust badge, value prop, value proposition, tagline, ad badge

                KEYWORDS: callout, selling point, trust signal, value prop, badge, free shipping, money back, guarantee, support, no fees, google ads, extension

                WHEN TO USE:
                - "Add a 'Free Shipping' callout to our Google Ads library"
                - "Create a callout for 24/7 support"
                - "Register a new value-prop tag for the holiday campaigns"
                - "I want a 'Money-Back Guarantee' badge to show under our ads"

                WHEN NOT TO USE:
                - Want a clickable shortcut to a landing page → use create_google_sitelink_extension
                - Want a list of named items (e.g. "Brands: Nest, Nexus") → use create_google_structured_snippet_extension
                - Same callout for Microsoft Ads / Bing → use create_microsoft_callout_extension
                - Anything for Facebook / LinkedIn / Reddit — search-channel-only

                INPUTS:
                - callout_text: visible snippet (1-25 chars).
