The article also flags AI shopping insights rolled out May 28 and two deadlines: the legacy UploadClickConversions request is blocked after June 15 for those who have not used it in the past 180 days, and enforcement of a 37-month limit on granular reporting data begins in June.

The article reports that four formats were unveiled on May 20: Conversational Discovery ads, Highlighted Answers, AI-powered Shopping ads, and Business Agent for Leads.

## How does the chatbot inside lead generation ads change lead qualification?

The article states that Business Agent for Leads embeds an AI chatbot directly inside lead generation ads instead of sending users to a landing page form. The agent is trained on the advertiser’s website content and qualifies prospects through conversation before they reach the CRM. The article says the format is targeted first at education, finance, and professional services.
