Quick Answer

  • Combine affinity (interest) with in-market (intent) for a "professionally interested AND actively shopping" audience layer

How Affinity Audiences Works

Google builds affinity audience segments by analyzing sustained behavioral patterns, what users repeatedly watch, read, search for, and engage with over extended periods. Unlike in-market audiences (which capture short-term purchase research), affinity audiences reflect durable interests and identities. There are hundreds of standard affinity segments including "Technology Enthusiasts," "Business Professionals," "Avid Investors," and custom affinity audiences you can build using specific URLs and keyword themes to create proprietary segments. Affinity audiences are available across Google Display, YouTube, and Discovery campaigns.

Why Affinity Audiences Matters for B2B Marketing

For B2B Google Ads, affinity audiences are most valuable in upper-funnel awareness campaigns where the goal is reaching professionals with relevant interests before they enter active purchase research. "Business Professionals" and "Technology Enthusiasts" affinity segments provide broad B2B-relevant reach on the Display Network and YouTube. Custom affinity audiences, built by entering competitor URLs, industry publication domains, and professional development topic keywords, can create highly relevant B2B audience segments tailored to specific buyer personas.

Affinity Audiences: Best Practices & Strategic Application

Best practices for affinity audiences in B2B include: using standard affinity audiences in observation mode on Search to identify whether specific professional interest groups convert differently, building custom affinity audiences by entering 5-10 competitor domains and 10-15 industry keywords to create a proprietary "active B2B category researcher" segment, combining affinity with in-market audiences for a "interested AND currently shopping" audience layer, and using affinity segments on YouTube for brand awareness campaigns targeting professional content consumers.

Agency Perspective: Affinity Audiences in Practice

MV3 Marketing builds custom affinity audiences for B2B clients by combining competitor URLs, industry trade publication domains, and topic keyword sets. These custom segments often outperform standard affinity categories because they are precisely calibrated to the specific professional interests of each client's ICP, creating a proprietary targeting layer unavailable to competitors using only default audiences.
