Google Ads for LED Therapy Brands: The Honest Performance Report

The Google Ads Landscape for LED Therapy

What You’re Actually Competing Against

Google Ads for beauty and wellness products are expensive and competitive. Search volume for key terms is real, but so is the competition.

High-volume search terms:

• “LED face mask” — 18,100 monthly searches (US)
• “Red light therapy” — 33,100 monthly searches (US)
• “Light therapy for skin” — 14,800 monthly searches (US)

The competition problem: Beauty brands, medical device companies, and established wellness brands all bid on these terms. CPC (cost per click) for competitive beauty/wellness terms ranges from $1.50 to $8.00 in our experience.

The quality score problem: Google rewards high-quality ads with lower costs. If your landing page loads slowly, your quality score drops and your costs rise.

Regulatory Constraints on Google Ads for Wellness Products

Google has specific policies for health and wellness advertising. LED therapy devices face specific restrictions:

Claim restrictions: You cannot make claims that imply medical treatment or cure without specific certifications. “Treats acne” is different from “may help improve skin appearance.” The first requires medical device classification; the second doesn’t.

Before and after imagery: Google restricts before-and-after claims in many health categories. LED therapy devices often fall into this restriction.

Claim substantiation: Any claim you make must be substantiable. If Google asks you to substantiate “clinical-grade LEDs” and you can’t, your ad gets disapproved.

We had multiple ad disapprovals in our first months. Learning Google’s health claims policies was a real cost.

What Actually Worked

Search: Branded Campaigns

Performance: 5.8x ROAS

Brand-name campaigns (bidding on our own brand terms) consistently performed best. These are people already looking for us. Conversion rates are high. CPC is low (typically $0.50-1.50 because quality scores are high when landing on relevant pages).

Setup:

• Campaign type: Search
• Keywords: [brand name], [brand name] mask, [brand name] LED
• Negative keywords: exclude competitor names
• Bid strategy: Maximize conversions with ROAS target of 5.0x

Key insight: Never stop running brand campaigns. Even if they seem unnecessary (who would search for our brand name except us?), competitors may bid on your brand terms, and branded campaigns capture that traffic before competitors do.

Shopping: Mid-Funnel Products

Performance: 3.1x ROAS

Google Shopping campaigns (product listing ads) performed reasonably well for our mid-priced products ($79-129).

Setup:

• Campaign type: Shopping
• Product categories: segmented by price tier
• Bid strategy: Smart Shopping with ROAS target of 3.0x
• Ad schedule: Reduced bids on weekends (our B2B audience searches Monday-Thursday)

What works on Shopping:

• Clear, professional product images (white background works best)
• Accurate, specific product titles (LED therapy mask, red light, 192 LEDs)
• Competitive pricing (Shopping shows price comparisons; if you’re 30% above competitors, you don’t get clicks)

What doesn’t work on Shopping:

• Premium products above $200 (conversion rate too low to justify Shopping costs)
• Products with complex differentiation (Shopping shows price and image; explanation doesn’t fit)

Search: Informational Intent Keywords

Performance: 2.9x ROAS

Surprisingly, informational keywords performed reasonably well. People searching “best LED face mask for acne” or “red light therapy how it works” are often in research mode — but they’re also often ready to buy.

Setup:

• Campaign type: Search
• Keywords: “best LED face mask,” “LED mask for [skin concern],” “red light therapy [specific use]”
• Ad copy: Focus on educational content with clear value proposition
• Landing page: Dedicated landing pages matching the specific query intent

Key insight: Create dedicated landing pages for each major informational keyword theme. “LED mask for acne” should go to a page specifically about acne treatment, not your homepage.

YouTube: Brand Awareness

Performance: 1.4x ROAS (but brand search increased 40% post-campaign)

YouTube ads don’t convert directly well for high-consideration purchases. We don’t expect someone to watch a YouTube ad and immediately buy a $99 device.

What YouTube does is build brand awareness that feeds into Search performance.

Setup:

• Campaign type: Video (In-stream)
• Targeting: Custom intent audiences (people who searched related terms), lookalike audiences from existing customers
• Budget: 20% of total Google Ads budget
• Creative: 15-second demonstrative video showing the product in use, with clear CTA at end

Measurement challenge: YouTube’s direct attribution is poor. You need to track brand search lift, branded traffic increase, and view-through conversion windows (28 days) to see the real impact.

What Didn’t Work

Search: Non-Brand, High-CPC Keywords

Performance: 0.9x ROAS

Generic beauty keywords (“face mask,” “skincare device”) at high volume were too expensive. Conversion rates weren’t high enough to justify the CPC.

We tested and failed with:

• “face mask” — $6.50 CPC, 0.3% conversion rate, $21.67 cost per conversion
• “LED skin device” — $4.80 CPC, 0.5% conversion rate, $9.60 cost per conversion
• “beauty tech” — $5.20 CPC, 0.2% conversion rate, $26.00 cost per conversion

Lesson learned: Not all search volume is worth buying. Some keywords have high volume but low purchase intent. Test, measure honestly, and cut losers fast.

Display Campaigns

Performance: 0.3x ROAS

Display advertising (banner ads across Google’s network of websites) for our products was terrible. LED therapy devices aren’t impulse purchases; display advertising doesn’t work for this product category.

We wasted $8,000 on display before shutting it down.

When display works: For brands with lower consideration products, retargeting (showing ads to people who visited your site but didn’t buy), or brand awareness for large consumer brands with massive budgets.

Retargeting at Aggressive Bids

Performance: Variable

Retargeting (showing ads to people who already visited your site) has a mixed track record. When we bid too aggressively, we wasted budget on people who weren’t going to convert. When we bid conservatively, retargeting was profitable.

Effective retargeting setup:

• Segment audiences by behavior (visited homepage vs. visited product page vs. added to cart vs. started checkout)
• Bid aggressively only on checkout abandoners (highest intent)
• Bid conservatively on homepage visitors (lower intent)
• Use frequency caps (don’t show the same person an ad 20 times)

The Measurement Framework That Prevents Waste

Without proper measurement, Google Ads spend is just a guess. Here’s what we built:

Conversion Tracking (Non-Negotiable Foundation)

Install Google Tag Manager and configure:

• Page view tracking
• Add-to-cart tracking
• Checkout initiation tracking
• Purchase tracking with transaction value

Without this, you can’t measure ROAS. You can’t optimize. You’re flying blind.

Attribution Model Selection

Google Ads provides multiple attribution models:

• Last click (all credit to final click before purchase)
• First click (all credit to first interaction)
• Data-driven (Google’s algorithm-based model)
• Position-based (credit distributed across the journey)

For LED therapy devices (which have longer consideration cycles), we use data-driven attribution. This gives credit to the channels that actually influence purchase, which for us is often YouTube (awareness) followed by Search (conversion).

Last-click attribution undervalues YouTube and overvalues Search. Data-driven attribution is more accurate but requires sufficient conversion volume to model.

The ROAS Target by Campaign Type

Campaign Type	Target ROAS	Notes
Brand Search	5.0x+	These should be your most efficient campaigns
Shopping (mid-price)	3.0x	Primary revenue driver
Non-brand Search	2.0x	Acceptable if it drives volume
Retargeting	2.5x	Higher cost, needs careful management
YouTube	1.5x	Measure via brand search lift
Display	0.5x	Only acceptable if doing major brand campaign

The Optimization Process

Every week, we do a 30-minute optimization session:

Checklist:

• Review search term report: add negative keywords for irrelevant searches
• Review impression share: are we showing for target keywords?
• Pause underperforming ad groups: campaigns with ROAS below 1.0x get paused immediately
• Adjust bids based on day-of-week performance
• Review ad creative performance: which ad variations are winning?
• Check for policy disapprovals: review any disapproved ads

Monthly:

• Review keyword performance: add new keywords that are converting, pause keywords that aren’t
• Review landing page performance: are high-traffic keywords going to the right pages?
• Competitive analysis: what are competitors bidding on, and how does it affect our CPC?
• Budget allocation: shift budget toward high-performing campaign types

The Honest Assessment

Google Ads is a viable customer acquisition channel for LED therapy brands, but not an easy one. The brands that succeed:

• Start with branded campaigns — build your foundation before spending on competitive terms
• Measure honestly — if a campaign doesn’t hit target ROAS after 60 days, cut it
• Match intent to landing page — don’t send generic keyword traffic to your homepage
• Set realistic ROAS targets — 3-5x is achievable for well-optimized campaigns; 10x is not realistic for competitive categories
• Build the full funnel — use YouTube for awareness, Search for consideration, Shopping for conversion

The brands that fail spend indiscriminately, measure poorly, and expect Google Ads to fix a product or pricing problem it can’t.

Put the product and pricing in order first. Then spend on Google Ads to drive qualified traffic to a conversion-optimized experience. That combination works.
