If your Performance Max (PMax) campaign is sending irrelevant traffic to your B2B site, here’s what’s likely going wrong and what you can do to fix it.
PMax is designed for broad automation
It uses Google's signals to find conversions, but it doesn’t always understand B2B intent properly, especially if your site or assets aren't clearly signaling who your ideal customer is.
No strong audience signals or intent-based targeting
If you didn’t provide custom segments (like people who’ve searched B2B-related terms or visited relevant URLs), Google guesses — and often shows your ads to consumers or low-quality users.
Your creative assets are too generic.
PMax matches assets to placements based on themes. If your headlines, videos, or images aren’t clearly B2B-focused, Google may place your ads on YouTube kids’ channels, mobile apps, or consumer-oriented placements.
Final URL Expansion is on (default)
This lets Google send users to any page on your site — including irrelevant ones like blog posts or careers pages — which can lead to unqualified traffic.
How to fix it:
1. Turn off Final URL Expansion
2. Use strong audience signals
Add custom segments like:
“People who searched for B2B software,” “enterprise solutions,” or “[your competitor]”
Website visitors from your CRM list or LinkedIn leads
This guides Google toward more relevant users.
3. Create B2B-focused asset groups
Use headlines and descriptions that clearly speak to business buyers, not general consumers.
Examples:
“Built for IT Managers & Enterprise Teams”
“Secure Solutions for Finance Teams”
Avoid fluffy or lifestyle-based copy
4. Monitor search themes and placements
In your PMax campaign → Insights → Search Term Themes
→ See if Google is matching your ads to off-topic searches
Under “Placements,” check where your ads are showing (e.g., mobile games = red flag)
5. Run a Search campaign alongside PMax
Sometimes, it's better to control B2B traffic via standard Search ads while using PMax only for remarketing or warm traffic.
