When you’re running a B2B Medicare insurance campaign, your goal is likely to reach brokers, agencies, or business partners — not individual consumers looking for personal coverage. Yet many advertisers find themselves struggling with this exact problem:
You carefully set up your Google Ads with phrase match keywords targeting B2B intent — and still, you’re getting B2C (business-to-consumer) search terms like “Medicare plans near me” or “best Medicare insurance for seniors.”
Why is this happening?
And more importantly: how can you fix it without ruining your campaign reach or quality?
This article dives deep into the intent mismatch caused by phrase match keywords, explains why negative keywords are critical in such cases, and provides a complete strategy to clean your traffic and focus purely on B2B Medicare leads.
Let’s start from the top.
The Problem: Phrase Match is Letting B2C Traffic In
Phrase match used to be more strict — it matched queries containing your keyword in order and often with close variants.
But since the 2021 Google Ads update, phrase match behaves more like broad match modified used to. This means:
- Google can match your phrase match keyword to queries that include similar meanings or implied intent.
- Google’s AI may interpret B2C terms as “related enough” to your keyword — even when it clearly isn’t for your target.
Example:
Let’s say you’re bidding on:
medicare insurance for businessesgroup medicare coveragemedicare broker partnerships
You might find your search term report includes phrases like:
- “medicare insurance near me”
- “apply for medicare”
- “how to get medicare part b”
- “medicare plans for seniors”
These are clearly B2C searches — coming from consumers, not companies.
And if you’re not watching carefully, you’ll waste budget on clicks that can never convert to your intended B2B goals.
Why This Happens: Phrase Match Limitations in Google Ads
Phrase match isn’t perfect for complex or niche audience intent, like B2B.
Here’s what’s causing it:
1. Semantic Match Expansion
Google is now using machine learning to “understand the meaning” behind your keyword — but it often misses context.
In the Medicare industry, Google might think:
- “Group Medicare” and “Medicare Advantage” are related.
- “Medicare insurance for business” and “apply for Medicare” are close.
But in reality, they are totally different audiences.
2. Insufficient Negative Keywords
Without B2C-specific negatives, Google has no reason not to match your keywords to high-volume B2C queries that look “relevant.”
3. Broad Match Bias in Auction
Even with phrase match, Google may prioritize impressions that historically perform well in terms of CTR and volume — which favors B2C because more users are searching for personal Medicare help.
The Hidden Cost of B2C Traffic in B2B Campaigns
Let’s look at the consequences of letting B2C queries sneak into your B2B Medicare campaign.
🔥 Wasted Budget
You’re paying for clicks from consumers who won’t buy your service — they’re not brokers, not HR managers, not agency partners.
📉 Lower Quality Scores
When users bounce because your ad is not for them, it tanks your engagement rate and relevance score, which drives up your CPC (cost-per-click).
💥 Distorted Conversion Metrics
You may see clicks but no conversions, confusing your performance tracking and causing false decisions.
🧪 Poor Audience Signals
Google Ads uses historical click behavior to optimize your campaign. B2C traffic poisons your learning signals and makes it harder to reach true B2B prospects.
The Solution: Why You Must Negative Out B2C Search Terms
To fix this, you need to be aggressive and strategic about negative keywords.
🎯 Negative Keywords: Your Filter Against B2C
Negative keywords tell Google what NOT to match — and they are essential in B2B campaigns with overlapping industries like insurance.
✅ What B2C Terms to Negative Out
Build a master B2C blocklist that includes terms like:
- “apply for Medicare”
- “get Medicare”
- “medicare near me”
- “medicare part a/b/c/d”
- “enroll in Medicare”
- “senior citizen”
- “over 65”
- “Medicare for parents”
- “free Medicare consultation”
- “compare plans”
- “eligibility for Medicare”
These phrases are great for B2C agents, but toxic for B2B strategy.
Use exact and phrase negative matches to exclude this traffic entirely.
The Strategy: A Step-by-Step Approach to Clean & Optimize Your Campaign
Here’s how to clean up your B2B Medicare campaign and make sure you’re only targeting qualified business traffic.
Step 1: Audit Your Search Terms Weekly
Head to your Search Terms Report in Google Ads. Look for:
- High impressions but low CTR
- Irrelevant consumer-focused queries
- Any non-business search behavior
Highlight and label B2C patterns.
Step 2: Build Your Negative Keyword Lists
Create separate Negative Keyword Lists in Google Ads:
🧱 List 1: B2C Medicare Terms
- “how to apply for medicare”
- “medicare enrollment”
- “seniors”
- “medicare part d drug plan”
- “free medicare help”
🧱 List 2: Geographical Mismatch
If you’re not nationwide:
- “medicare in Florida” (if you’re not targeting Florida)
🧱 List 3: Competitor or Branded Queries (optional)
If you don’t want traffic looking for Aetna, Humana, etc.
Step 3: Refine Your Ad Copy to Signal B2B Intent
Write ad headlines and descriptions that make it obvious you’re targeting businesses.
✅ Good Example:
“Partner With Us to Offer Medicare Plans” “Medicare Coverage for Employer Groups & Brokers” “Group Medicare Solutions | Licensed B2B Agency”
This discourages consumer clicks and improves quality of leads.
Step 4: Use B2B-Focused Landing Pages
Your landing page must speak to:
- HR professionals
- Group plan decision-makers
- Insurance brokers
Avoid language like “Get a Free Quote Now” or “Find Your Plan” — that sounds B2C.
Instead, use CTAs like:
- “Partner With Us”
- “Become a Broker”
- “Schedule a Business Consultation”
Step 5: Layer Your Audience Targeting
Use audience signals to further filter traffic:
- Add In-Market Audiences like:
- Use Exclusions to remove:
Step 6: Run Campaign Experiments
Create an experiment A/B split test:
- One campaign with broader phrase match + negatives
- Another with exact match only keywords
Measure which one drives better lead quality and conversion rate.
Step 7: Use GA4 or CRM to Trace Lead Quality
Track lead data across platforms:
- Connect Google Ads → GA4 → CRM
- Check what keywords actually result in qualified calls, meetings, or broker sign-ups
This gives you a feedback loop to trim any keyword that leads to unqualified traffic.
Advanced Tip: Try Custom Segments in Performance Max
If you’re running PMax campaigns, they tend to be aggressive.
Use custom audience segments:
- Website visitors from B2B partner pages
- Lookalikes based on uploaded B2B customer data
- Interest in “Group Insurance” or “Employer Health Coverage”
This helps steer Google’s machine learning toward B2B intent.
