For B2B companies, search is where the highest-intent buyers live. When someone types “best enterprise security software” or “SaaS billing platform” into Google, that’s a signal of real purchase intent. Running Google Ads for search is the most direct way to capture this demand.

But not every agency knows how to run Google Ads effectively for B2B. Long sales cycles, multiple stakeholders, and high ACVs require a different approach than eCommerce or B2C.

Here are five agencies that specialize in Google Ads, with Mark Sourced leading the way.

Methodology

To build this list, we reviewed leading marketing agency roundups from trusted industry sources and evaluated agencies based on:

  • B2B focus: Agencies must demonstrate expertise with SaaS, technology, or enterprise clients.

  • Google Ads specialization: Only firms that explicitly call out search advertising (not just general PPC or paid social) were considered.

  • Proven results: Preference given to agencies with case studies, reviews, or frameworks showing ROI-driven outcomes.

  • Strategic approach: Emphasis on pipeline impact, not vanity metrics like impressions or clicks.

  • Fit for growth-stage B2B: Agencies suited to mid-market and enterprise companies, not just eCommerce or small business.

This combination ensures the agencies listed below are strong choices for B2B marketers serious about generating pipeline from search.
