Negative keywords for dental practices (Google Ads list)

Dental campaigns have unusual patterns compared to home services because of the insurance and pre-purchase research behavior. The blocks below catch most of the universal junk; the insurance-specific filters are where dental campaigns differ from other industries.

The pattern

Dental search behavior splits into three buckets:

1. Ready buyers: "dentist near me," "emergency dentist," "[city] dentist accepting new patients"
2. Insurance-bound shoppers: "dentists that take aetna," "delta dental dentist near me" (only relevant if you accept that insurance)
3. Researchers and information seekers: "what does a root canal cost," "is invisalign worth it," "implant vs bridge"

The third bucket is where most waste accumulates. Researchers click ads, read content, and leave without booking. They may book months later, but the immediate ROI is poor.

Dental-specific judgment calls

Insurance names (delta dental, cigna, aetna, blue cross): do not block these. If you accept the insurance, queries with the name are high-intent buyers. If you do not accept it, you may still want the impression for brand awareness. only phrase-block if your conversion rate from those queries is consistently zero.

cost and price: both are high-intent buyer signals AND researcher signals. Do not broad-block. If your campaign is conversion-rate sensitive, phrase-block patterns like "average cost" and "how much does" but leave bare "cost" alone.

emergency: keep. Always.

pediatric when you do general adult dentistry: phrase-block "pediatric dentist" if your search terms report shows it converting poorly.

Service-line filters

If you do not offer specific services, phrase-block them:

• No orthodontics: phrase-block "braces consultation," "invisalign cost"
• No cosmetic: phrase-block "veneers cost," "teeth whitening service"
• No surgery: phrase-block "wisdom teeth removal," "tooth extraction surgery"
• No pediatric: phrase-block "child dentist," "kids dental"

Apply these per ad group rather than account-wide if your campaigns are split by service line.

Geographic blocks

Dental service is mostly hyper-local: patients drive 15-30 minutes max. Out-of-area queries are rarely valuable.

Common geo blocks: nearby cities your patient base does not come from, out-of-state names, distant suburbs.

What good looks like

A typical general dentistry practice after a sweep:

• 20-30% reduction in low-quality clicks
• Conversion rate up by 30-60% (because researchers no longer dilute the buyer pool)
• Cost-per-new-patient improves materially within 6-8 weeks (longer than home services because dental booking lag is longer)

The list is the start. Your search terms report shows insurance and service-line patterns specific to your practice. Sweep monthly.
