Choosing the right Google Ads agency can make the difference between wasted budget and campaigns that genuinely drive growth. But what should you look for if you’re a B2B business: where sales cycles are longer, decision-making is complex, and the metrics that matter go far beyond clicks?

Here’s what a great B2B Google Ads agency should deliver:

1. A Strategy That’s Built for B2B

B2B isn’t just B2C with a different target audience. A great agency understands the nuances of longer sales funnels, multiple stakeholders, and the importance of nurturing leads — not just generating them. That means building campaigns around the entire journey, from awareness through to conversion and beyond.

2. Crystal-Clear Measurement

Clicks and impressions are vanity metrics if they’re not tied back to revenue. Your agency should set up robust tracking across the funnel, from first touchpoint through to SQLs and closed deals. This often means connecting Google Ads data to your CRM so you can actually see which campaigns are driving business outcomes.

3. Smart Audience Targeting

In B2B, the audience pool is smaller and more specialised. A great agency knows how to use a mix of first-party data, remarketing, and intent-based targeting to reach the right people, while avoiding wasted spend on those who’ll never buy.

4. Compelling Creative & Messaging

Google Ads isn’t just about keywords and bids. Strong ad copy and creative that speaks directly to your audience’s pain points is what makes campaigns cut through. Look for an agency that doesn’t just optimise spreadsheets, but also invests time in crafting messaging that resonates.

5. A Testing Mindset

Markets shift. Competitors change strategy. What worked last quarter might not work today. A great agency runs structured tests on ad copy and landing pages to bidding strategies and campaign types. This continuously improves performance over time. 

6. Proactive Communication

You don’t want an agency that only surfaces when it’s reporting time. The best partners are proactive: flagging opportunities, explaining performance shifts, and suggesting new approaches before you even have to ask.

7. Alignment with Sales

For B2B, marketing and sales alignment is everything. A great agency doesn’t just hand over leads; they work with you to make sure lead quality is strong, feedback is looped back into campaigns, and sales and marketing are rowing in the same direction.

Final Thoughts

A great B2B Google Ads agency is more than a vendor. They’re a partner who understands your market, your funnel, and your goals — and who’s committed to making your ad spend work as hard as possible.

If you’re evaluating agencies, look beyond the case studies and promises. Ask the tough questions about measurement, strategy, and communication. The right agency won’t just run your campaigns, they’ll help you grow.
