In terms of offline conversions Google Ads attributes to a campaign, these are sales or leads that happen outside your website. Google Ads offline conversion tracking covers sales or leads that happen outside your website. Common types include:

• In-store purchases – a customer sees your ad, then visits your physical location and buys.
• Phone orders and leads – a customer calls your business (e.g., to schedule a consultation) after seeing your ad, and the conversion is attributed once the call results in a sale or qualified lead.
• Upsells and cross-sells – additional revenue generated after the initial conversion, sent back to Google Ads to reflect true customer value.
• CRM-qualified leads – leads captured in a CRM (or a lightweight Google Sheet setup) that later convert to paying customers offline.
