How to choose a Google Ads agency for enterprise B2B: what the Partner badge does not tell you

A VP of demand generation usually inherits one of two accounts. The first optimizes to form fills, so it buys cheap leads from students, job seekers and small companies that never become pipeline. The second is so cautious it only bids on brand terms and reports a great return on spend that would have arrived anyway.

Both share a root cause: Google’s bidding sees the conversion you give it. If that conversion is a form fill, smart bidding finds more form fills. Enterprise B2B needs Google Ads to learn from what happens later, in the CRM.

Google’s requirements for Partner status are specific. The agency’s manager account needs a minimum optimization score of 70%, US$10,000 of spend over 90 days across managed accounts, and at least 50% of account strategists holding Google Ads certifications. Premier Partner status goes to the top 3% of participating companies in a country, ranked on factors such as client growth, client acquisition, retention, spend diversification and total annual spend.

Those thresholds tell you an agency manages a certain amount of spend and keeps accounts in line with Google’s recommendations. They do not measure whether the agency can build B2B pipeline, and optimization score rises when you accept Google’s recommendations, some of which raise spend. Treat the badge as a minimum, not a decision.

Google Ads offline conversion imports let you send results that happen after the click, such as a sales-qualified lead or an opportunity, back to Google Ads. Google describes two match keys: the Google Click ID (GCLID) saved with each lead, and user-provided data such as email addresses, hashed and matched through enhanced conversions for leads. The two can be combined.

Google also states that from June 15, 2026, offline conversion and enhanced conversions for leads uploads move to the Data Manager API and are blocked in the Google Ads API. If an agency built your imports on the old method, ask how it was migrated.

• Which conversion will our campaigns bid toward in month one, month three and month six?
• How will CRM stages reach Google Ads, and who owns that connection?
• How do you separate buying-intent searches from research searches in budget and reporting?
• What does your monthly report show, and does it reconcile with our CRM?
• How are you paid, and does your fee rise when spend rises regardless of results?

1. Baseline cost per qualified lead and cost per opportunity from the CRM for the last two quarters.
2. Agree the conversion hierarchy: form fill, qualified lead, opportunity, closed won, with a value for each.
3. Review search terms and negatives at least weekly in the first month.
4. Report pipeline created and cost per opportunity monthly, by campaign and by intent tier.
5. Move bidding to qualified stages once there is enough conversion volume, and compare results quarter over quarter.

We build Google Ads around CRM outcomes: offline conversions, value-based bidding when the data supports it, search structure by buying intent and reporting in pipeline terms. For KNIME, rebuilding measurement, targeting and landing pages delivered a 51% lower cost per lead, with 9 in 10 leads verified in the CRM and 100% of paid leads traceable to closed deals.
