The classic lead-gen Google Ads account optimises to 'cost per lead' where a lead is a form fill. That metric looks great in reports and means nothing in your CRM. The agency reports R350 cost per lead. Your sales team tells you most of those leads are junk, and the actual cost per qualified opportunity is R1,800. The bid model never sees that, so it keeps optimising for more of the wrong queries.
The fix is CRM integration: offline conversion import from HubSpot, Salesforce, Pipedrive, Zoho, or whatever you use. Closed-won deals get imported back to Google Ads as the real conversion event. Smart Bidding switches optimisation target from form fill to SQL or to revenue. Within 4 to 6 weeks, the algorithm starts shifting budget toward the queries and audiences that actually produce qualified pipeline. Sometimes that means a 'cost per lead' that goes up while cost per SQL and cost per closed-won halve. That is the right trade.
Beyond the tracking, lead-gen needs different remarketing, different ad copy (less price-led, more credibility-led), and different landing pages (longer-form, more social proof, often video) than ecommerce. The cycle is weeks, not minutes. The remarketing journey has to acknowledge that. Most agencies run an ecommerce playbook on a lead-gen account and wonder why the close rate is low.
