Amazon Ads vs Google Ads: Which Is Better for Your Local Business?
Both Amazon and Google run pay-per-click advertising. Both put your business in front of people who are actively searching. And both can drive meaningful revenue for the right business.
But they serve fundamentally different buyer journeys — and using the wrong one means spending money where your customers aren't.
Here's the clearest comparison you'll find, written for local business owners who don't have time for vague "it depends" answers.
The Core Difference in One Sentence
Google Ads capture people looking for a solution. Amazon Ads capture people ready to buy a specific product.
When someone searches "plumber near me" on Google, they need a plumber. Now. That search doesn't happen on Amazon.
When someone searches "natural dog shampoo" on Amazon, they're not researching — they're buying. That buying intent doesn't exist in the same way on Google.
This single distinction explains 80% of the channel selection decision.
Who Should Use Google Ads
Google Ads are the right primary channel for:
- Local service businesses — plumbers, electricians, cleaners, HVAC, landscapers. Your customers search Google, not Amazon.
- Appointment-based businesses — hair salons, barbershops, yoga studios, dental practices. Google + Google Maps is where local discovery happens.
- Any business without physical products to sell. Google works for services; Amazon requires something to put in a cart.
- Businesses targeting a specific geographic area. Google's local targeting (radius, zip code, city) is significantly more precise than Amazon's.
If you are a local service business, stop reading about Amazon Ads. Your budget belongs in Google Ads and Google Business Profile. The ROI is dramatically higher.
Pro Tip
Local service businesses consistently see 3–10× better ROI from Google Ads than any other paid channel. The search intent is unmatched — "emergency plumber [city]" converts at 15–25%.
Who Should Use Amazon Ads
Amazon Ads are the right channel for:
- Product-based businesses already selling (or willing to sell) on Amazon — specialty food producers, pet product makers, beauty brands, supplement companies.
- Local businesses with a product line — the coffee shop that ships its beans nationally, the pet groomer who sells branded grooming kits online, the salon that sells professional haircare.
- Businesses where Amazon search intent is high — if someone would naturally search Amazon for what you sell, you should be there.
- Brands wanting to reach older, higher-income shoppers — Amazon's demographic skews affluent compared to social platforms.
The Buyer Journey: Why Platform Matters
Search Intent by Platform

95%Google Shopping
75%Google Search
70%Meta Ads
35%Instagram
30%Estimated purchase intent score — how close users are to buying when they see your ad
Amazon buyers are at the bottom of the funnel by definition. They're on a commerce platform with their payment details saved, Prime membership active, and trust already established. Conversion rates for Amazon Sponsored Products typically run 10–15% — three to five times higher than Google Shopping or social ads.
Google Search buyers have high intent but haven't necessarily chosen a provider yet. They're comparing options, reading reviews, checking websites. For service businesses, that consideration phase works in your favour if you have strong reviews and a fast website.

Varies by audience
Amazon's CPC is often lower than Google's — but this comparison can be misleading. Amazon charges referral fees (8–15% of sale price) on every conversion, plus any FBA costs. The true cost per acquisition on Amazon is often higher than the CPC suggests.
For service businesses, there are no product fees on Google — you pay per click, and the margin on a job is yours.
Setup Complexity
Google Ads requires: a Google account, campaign setup, keyword research, ad copy, and a landing page. You can be live in a day.
Amazon Ads requires: an Amazon Seller Central account ($39.99/month), product listings with optimised content, inventory to fulfil orders, and compliance with Amazon's selling policies. Setup takes days to weeks before your first ad can run.
For speed to market, Google wins. For product-focused businesses already on Amazon, the setup cost is a one-time investment.
Should You Run Both?
For product-based local businesses that sell both locally (services) and online (products), running both makes sense — but with a clear division:
- Google Ads for your local service customers (targeting by location)
- Amazon Ads for your product customers (targeting by purchase intent)
A pet grooming salon that also sells branded grooming kits online is a perfect example. Google Ads drive grooming appointments. Amazon Ads sell products to customers across the country.
For pure service businesses: no. The Amazon budget is wasted. Consolidate everything into Google Ads, Google Business Profile, and local SEO.
The Decision Framework
Ask yourself these questions in order:
1. Do you sell a physical product someone could buy online?
- No → Use Google Ads. Stop here.
- Yes → Continue to question 2.
2. Would someone naturally search Amazon for that product?
- No → Google Shopping or Meta Ads are better fits.
- Yes → Amazon Ads are worth testing.
3. Are your product margins strong enough to absorb Amazon's 8–15% referral fee?
- No → Sell through your own website with Google/Meta Ads driving traffic.
- Yes → Amazon Ads are a viable channel.
4. Do you already have (or can you build) a presence on Amazon?
- No → Start with Google/Meta while building your Amazon presence.
- Yes → Run Amazon Ads now.
The Bottom Line
Google Ads and Amazon Ads are not competitors for most local businesses — they serve different customers at different stages of a different journey.
If you're a local service business: Google Ads, full stop. Amazon is not where your customers are.
If you're a product-based local business: both platforms deserve a place in your strategy, with Google handling local service searches and Amazon capturing product purchase intent.

Common Mistakes to Avoid
Even experienced local business owners make the same five errors when choosing between Amazon and Google Ads. Here’s exactly what they do wrong — and how to fix it before your next campaign.
Mistake #1: Running Both Channels Simultaneously with the Same Budget
The most expensive mistake we see at DataLatte.pro is a coffee shop owner or a pet groomer splitting their modest budget — say, $500 per month — evenly between Amazon and Google from day one. They reason, “I’ll test both and see which works.” What actually happens: neither campaign gets enough data to optimize, both platforms serve ads to cold or irrelevant audiences, and the owner quits both after 90 days, convinced that paid ads don’t work.
The fix: Put 100% of your first month’s budget into one channel. If you sell a physical product (bottled cold brew, dog shampoo, hair styling tools), start with Amazon. If you provide a service or appointment (dog grooming, haircut, fitness class), start with Google. A single channel with $500 gets roughly 150–200 clicks on Google or 100–150 purchases on Amazon in a month — enough data to know if the approach scales. After you see a positive return (even a small one), add the second channel with new, incremental budget. Don’t split $500 into $250 each. That buys you nothing but confusion.
Mistake #2: Ignoring Local Relevance in Keyword Selection
A yoga studio in Sydney runs Google Ads targeting the keyword “yoga classes.” They get clicks from people in London searching for yoga videos. A hair salon in Austin bids on “hair color” on Amazon — and their product page shows up next to national brands with 10,000 reviews. Neither gets sales because the context is wrong.
The fix: On Google, use location-specific keywords every time. Not just “plumber” but “emergency plumber in Leeds” or “plumber near me [postcode].” Add negative keywords to exclude searches from outside your service area — “online,” “video,” “virtual,” and city names you don’t serve. On Amazon, avoid generic product keywords until you have at least 50 reviews. Instead, bid on long-tail phrases like “hypoallergenic dog shampoo for sensitive skin” or “organic coffee beans for espresso machine.” These have lower search volume but convert at 2x to 3x the rate of generic terms. A specific keyword that costs $0.80 per click but converts at 8% is far better than a broad one at $3.00 per click converting at 1.5%.
Mistake #3: Using the Same Ad Copy for Both Platforms
Local business owners often copy their Google text ad into Amazon’s sponsored ads. This fails because the buyer’s mindset is fundamentally different. On Google, the searcher wants to solve a problem — they respond to urgency, trust signals, and specific offers (“Free consultation,” “Book now,” “Same-day service”). On Amazon, the searcher wants confidence in the product — they need social proof, details, and clarity on what’s inside the box.
The fix: Write separate copy for each platform. For Google, lead with the benefit and a clear call to action: “Need a plumber in Manchester? Fast response. Fixed-price quotes. Book online in 60 seconds.” For Amazon, lead with the product name and key differentiator: “Natural Dog Shampoo – Oatmeal & Aloe – Soothes Itchy Skin – 16 oz – Made in USA.” Include bullet points on Amazon that mirror what your best reviews say. A data-driven tip: run your five highest-rated Amazon reviews through a word cloud tool. The most common phrases (“gentle,” “no tears,” “works fast”) should appear in your ad copy and product title. On Google, run your five best testimonials through the same tool. “Reliable,” “on time,” “professional” — those go in your ad extensions.
Mistake #4: Not Adjusting for Platform-Specific Timing and Seasonality
A pet groomer in Canada runs Google Ads consistently every month of the year but wonders why their cost-per-click doubles in December. A coffee roaster in the US runs Amazon Ads every day in January with the same bid, then misses the huge Christmas spike. Each platform has predictable patterns that local businesses ignore at their own expense.
The fix: Map your budget to the platform’s natural rhythm. On Google Ads for local services, clicks are cheapest Tuesday through Thursday (often 20–30% lower cost-per-click than Monday or Friday). Saturdays and Sundays can see high volume for last-minute services but often have lower conversion rates — people are browsing, not booking. Shift 70% of your weekly budget to Tuesday–Thursday, and reduce Saturday–Sunday spend by half unless you track strong weekend conversions. On Amazon, the revenue curve is brutal: Q4 (October–December) generates 40–50% of annual sales for many product-based local businesses, and costs per click rise proportionally. If you sell coffee beans or pet shampoo, increase your Amazon budget by 50–100% starting mid-September, and reduce it by 30% in January and February when demand drops. A data point: one of our clients, a local honey producer in the UK, spends £600 per month on Amazon Ads from April to September and just £200 per month from October to March. Their annual ROAS actually improves because they don’t waste money when searches are low.
Mistake #5: Forgetting to Track Offline Conversions
This is the silent killer. A hair salon spends $800 on Google Ads in March, gets 50 clicks, but only 2 online bookings. The owner panics, turns off the ads, and concludes Google doesn’t work. What they missed: 8 people called the number from the ad, and 5 walked in directly after seeing the ad on Google Maps. None of those conversions appeared in the ad dashboard.
The fix: Set up conversion tracking for phone calls (Google Ads offers call extensions and call-only ads — these track the call duration and assign it as a conversion when it lasts longer than 60 seconds). Add Google Analytics goals for “click-to-call” on mobile. For physical stores, use the Google Ads store visits measurement (activated when your business profile is linked and you meet a minimum number of clicks per week). For Amazon, the situation is simpler — conversions happen on-platform — but you still need to track attributed sales beyond the ACoS (Advertising Cost of Sales) metric. One of our clients, a boutique coffee seller, saw their Google Ads CPA (cost-per-acquisition) drop from $18 to $7 simply by enabling call tracking and store visit measurement. Those extra conversions turned a losing campaign into a profitable one overnight.
A Simple 3-Step Decision Framework for Choosing Your First Platform
If you’re still unsure whether Google or Amazon is right for your business, stop guessing. Use this framework. It takes ten minutes and removes the anxiety.
Step 1 — Classify your business type
Draw a line between service and product. If your business earns more than 60% of its revenue from a service — a haircut, a plumbing repair, a yoga class — you start with Google Ads. If your business earns more than 60% of its revenue from a physical product — roasted coffee beans, dog shampoo, candles — you start with Amazon Ads. There’s no jab-stepping. Pick the dominant revenue stream.
Step 2 — Validate with a $200 test
This is not a “throw money away” test. It’s a calibrated experiment. If you chose Google: create one campaign targeting your three most profitable services (e.g., “haircut,” “balayage,” “blow-dry”) with a local location modifier. Set a daily budget of $7 for seven days. That’s $49. Run it for one week. Do you get at least 15 clicks and at least 1 booked appointment or tracked phone call? If yes, scale to $200. If no, your problem is likely copy, audience, or landing page — fix before spending more. If you chose Amazon: pick your best-selling product. Create one Sponsored Products campaign with 10 keywords — 5 branded (your business name + product) and 5 non-branded long-tail (e.g., “small batch hazelnut coffee”). Set a daily budget of $7 for seven days. Do you get at least 5 sales at an ACoS under 30%? If yes, the channel works. If your ACoS is over 40% and you have no sales, your product page likely needs better images, reviews, or pricing — fix before spending more.
Step 3 — Decide if you’re a hybrid business
Many local businesses are hybrids: a coffee shop sells brewed drinks in-store (service) and also ships bags of beans (product). A pet groomer washes dogs in-shop (service) and sells collars, leashes, and treats (product). For hybrids, the winning move is almost always to use Google Ads for the service side and Amazon Ads for the product side. Do not try to use one platform for both. Google does a poor job selling physical products that require a cart to buy; Amazon does a poor job driving foot traffic to appointments. Our local bakery client in Melbourne runs Google Ads for “custom birthday cakes” (service — people call or visit) and Amazon Ads for “gluten-free brownie mix” (product — people buy online). Each channel serves a distinct buyer journey. They spend $400 per month on Google (generating 12–15 cake orders) and $300 per month on Amazon (generating 50–70 mix sales). Separating the channels let them optimize each journey independently.
How to Calculate Your Real Cost Per Customer (and Why It’s Different on Each Platform)
Many local business owners look at one number to decide if ads are working: cost-per-click (CPC) on Google or advertising cost of sales (ACoS) on Amazon. Both are misleading on their own. The real number you need is cost per acquired customer (CAC) — and it’s computed differently for each platform because the buyer journey differs.
On Google Ads, your CAC formula is:
(total ad spend + any call tracking fees) ÷ (booked appointments + tracked phone calls + store visits + online bookings)
Let’s use a concrete example. A dog grooming business in Austin spends $600 on Google Ads in a month. They get 80 clicks at $7.50 CPC. From those clicks, they receive:
- 4 online bookings
- 6 phone calls that last longer than 60 seconds (tracked via call extension)
- 2 walk-ins that mention the ad (store visit measurement)
Total conversions: 12. CAC = $600 ÷ 12 = $50 per customer. If the average grooming appointment is $75, they’re earning $25 per customer before labor costs — a positive return. But here’s the critical nuance: if they had only looked at online bookings (4 conversions), they’d see a CAC of $150 per customer and assume the ads were failing. That’s why offline conversion tracking is non-negotiable.
On Amazon Ads, your CAC formula is:
(ad spend) ÷ (number of attributed sales)
But you must factor in Amazon’s other fees. A local candle maker runs Amazon Ads for their signature soy candle. They spend $400 in a month. They make 40 attributed sales at $20 each — $800 in attributed revenue. Their ACoS is 50% ($400 ÷ $800). Most people would say that’s borderline. But here’s what’s hidden: Amazon also takes a referral fee (15% for most categories) and a fulfillment fee if using FBA (say $5 per candle). So from that $800 in revenue, Amazon deducts $120 in referral fees and $200 in fulfillment fees. Net to the seller: $800 – $120 – $200 – $400 (ad spend) = $80. That’s an 80% true cost of sale after advertising — far worse than the 50% ACoS implies. The real CAC, if you factor in all costs, is ($400 ad spend + $320 other fees) ÷ 40 sales = $18 per sale, on a $20 product. You’re making $2 per unit before your product cost.
The fix: Use a spreadsheet to compute total cost per customer, not just advertising cost. For Google, add $0.50–$1.00 per call for tracking software (if you use a third-party tool). For Amazon, add your referral fee, fulfillment fee, and any storage or long-term fees. A healthy CAC should be no more than 30–40% of your average customer lifetime value (LTV). If your LTV is low (under $50 per customer), you need a very tight CAC. If your LTV is high — say, a hair salon client who visits monthly for a year at $80 per visit — you can afford a higher CAC (up to $150–$200) and still profit over the customer’s lifetime.
When to Switch Platforms (and the Warning Signs That Tell You It’s Time)
Even after you choose a primary platform, the market changes. Your business grows. Competitors enter your keywords. Customer behavior shifts. Here are three specific signals that it’s time to seriously evaluate switching or adding the other platform.
Signal 1 — Your CAC on Google has doubled in 90 days.
This happens when more competitors in your area start running ads for the same keywords. A local plumber in a mid-sized UK city might have enjoyed a $15 CAC in January. By April, three new plumbing companies started Google Ads, and the CPC for “plumber near me” went from $4 to $8. The CAC now sits at $30. If this trend continues, the plumber hits a point where they can’t profit. The fix isn’t necessarily to abandon Google — but to explore Amazon if they sell products, or to pivot to a less competitive keyword (e.g., “gas safe plumber in [postcode]” instead of “plumber near me”). If your CAC rises for two consecutive months and you have a product to sell, test Amazon as a second channel with 20% of your current Google budget.
Signal 2 — Your Amazon organic rank isn’t improving despite consistent ad spend.
You’ve spent $2,000 on Amazon Sponsored Products over three months. You’re getting sales, but your product still appears on page 4 or 5 for your main keyword. This indicates that either your product is a commodity (low differentiation), your reviews are weak (under 30 reviews with a rating below 4.0), or you’re in a category dominated by big brands. In this scenario, Amazon Ads can become a treadmill — you pay for every sale and never build organic momentum. Consider that local service businesses often have better options on Google where differentiation (reviews, location, speed) is more powerful.
Signal 3 — Your customer acquisition channel mix is 100% one platform.
If all your new customers come from Google Ads (or all from Amazon), you have a single-point-of-failure risk. We’ve seen it happen: Amazon changes its algorithm or Google increases its local ad prices, and the business loses 30% of its revenue in a month. Diversification is healthy even if one channel dominates. Start small — allocate 10–15% of your total ad budget to the secondary platform for 60 days. If the test shows a positive ROAS (even a lower one than your primary channel), maintain it as a hedge. A local coffee roaster we work with gets 70% of customers from Amazon and 30% from Google Ads. When Amazon raised its referral fees by 2% last year, the roaster’s profit dipped but didn’t break — the Google Ads revenue held steady. That 30% cushion is worth more than a couple of percentage points of efficiency.
So here’s what it comes down to, friend: Amazon Ads and Google Ads aren’t enemies. They’re just different tools in your marketing kitchen. One is your espresso machine — fast, precise, perfect for customers who already know they want a shot. The other is your pour-over setup — warmer, more personal, ideal for serving the local community that walks in your door. Some weeks you’ll need both. Some weeks you’ll just need the one that’s brewing stronger for your business right now.
