What Makes a Great B2B Google Ads Agency?

Not every PPC agency understands B2B.

The best B2B Google Ads agencies typically have experience with:

• Longer buying journeys
• Multiple decision makers
• CRM integrations
• Offline conversion tracking
• Demand generation
• Account-Based Marketing (ABM)
• High-value lead generation
• Revenue attribution

If an agency only talks about impressions, clicks or CTR, they’re probably measuring the wrong metrics.

• Do you optimise for pipeline or just leads?
• Can you integrate with HubSpot or Salesforce?
• Who actually manages the account?
• How often will we meet?
• What reporting do you provide?
• Do you optimise landing pages?
• Can you produce ad creative?
