Ecommerce PPC services: setup cost, monthly fees, and what's included
Ecommerce PPC means buying clicks and conversions across product feeds, shopping engines, and marketplaces where purchase intent is highest.
What does ecommerce PPC include?
Ecommerce PPC services cover campaign setup, feed optimization, bid management, ad copy, and remarketing. A typical new-client setup costs between $1,000 and $5,000, and monthly management runs 10-20% of ad spend or a flat $500-$3,000. The work includes structuring campaigns by product category, setting up product listing ads (PLAs), and optimizing for mobile and desktop.
Feed optimization is a separate, critical task. Your product feed must have clean titles, accurate prices, stock status, and unique IDs. Many agencies use feed management tools like Feedonomics or DataFeedWatch. Without a clean feed, Shopping ads underperform regardless of bid strategy.
Remarketing is another standard component. A typical setup includes dynamic retargeting for users who viewed products but didn't buy, and cart abandonment sequences. These campaigns often deliver the highest ROAS, but require proper tagging and audience segmentation.

Google Shopping is the core
For most ecommerce stores, Google Shopping accounts for 60-80% of PPC revenue. Shopping ads use the product feed directly, so the merchant center must be healthy. Common issues: disapproved products, mismatched prices, or missing GTINs. A service provider will audit the feed monthly and fix errors.
Bidding on Shopping is different from search. You bid on product groups. Campaigns are often split by margin: high-margin products get higher bids, low-margin ones get capped. Typical CPCs range from $0.50 to $1.50 depending on category and competition.
Performance Max campaigns are replacing standard Shopping, but many specialists still prefer manual Shopping for control. A good provider tests PMax against standard Shopping and allocates budget to the winner based on ROAS.
Amazon PPC is a different beast
Amazon PPC includes Sponsored Products, Sponsored Brands, and Sponsored Display. The mechanics are simpler in some ways (no quality score) but more competitive. Bid management is all about ACoS: the ratio of ad spend to attributed sales. For established brands, a 15-20% ACoS is typical; for new products, 30-40% is normal until organic rankings build.
Keyword match types on Amazon are similar to Google: exact, phrase, broad. But broad match on Amazon is notoriously wasteful - I've seen accounts spend 50% of budget on irrelevant clicks. Negative keywords are underused. A good Amazon PPC service will add negatives weekly.
Most ecommerce PPC agencies offer separate Amazon management, but the skill set differs. If your Amazon spend exceeds $15k/month, a dedicated specialist usually pays off. Many agencies sub-contract Amazon work, which can lead to quality gaps.
PPC audit services: what gets checked
A PPC audit reviews account structure, wasted spend, negative keywords, quality score, and impression share. Audits are often used by advertisers switching agencies or evaluating performance. A typical audit costs $500 to $2,000 and takes 1-2 weeks.
Common findings: 20-30% of budget spent on irrelevant queries through broad match; daily budgets capped so low that the best campaigns lose impression share; and last-click attribution that undervalues upper-funnel campaigns.
An audit should include a clear action plan: new campaign structure, recommended bid adjustments, and a schedule for negative keyword pruning. Some agencies offer free audits as a lead generation tool, but independent auditors are often more objective.
Budget and ROAS expectations
Minimum effective budget for ecommerce PPC is about $1,000/month per channel. Below that, you cannot collect enough data for optimization. For Google Shopping, a daily budget of $50-$100 is a safe starting point. Facebook requires about $30-$50/day for consistent delivery.
ROAS varies by channel and category. In my experience, Google Shopping averages 2.5-5x, Amazon 3-8x, Facebook 1.5-3x. These numbers assume a correctly set up account and moderate competition. Categories like apparel have lower ROAS; electronics and furniture often higher.
ROAS is not profit margin. A 5x ROAS on a 20% margin product means break-even after ad costs, which is why targets get set against product margin rather than against a round number.
| Channel | Avg CPC ($) | Avg conversion rate (%) | Typical ROAS (revenue/spend) |
|---|---|---|---|
| Google Shopping | 0.50 - 1.50 | 2 - 4 | 2.5x - 5x |
| Amazon PPC | 0.80 - 1.20 | 8 - 12 | 3x - 8x |
| Facebook/Instagram | 0.30 - 0.80 | 1 - 3 | 1.5x - 3x |
| Microsoft Advertising | 0.40 - 1.00 | 2 - 4 | 2x - 4x |
In-house vs agency vs freelancer
The right choice depends on your spend and complexity. At less than $10k/month in PPC spend, a freelancer or part-time specialist usually makes sense. At $10k-$50k, an agency can provide more tools and bandwidth. Above $50k, you may want both in-house and agency support.
Agencies bring proprietary tools, established processes, and backup coverage. Freelancers offer lower overhead and direct communication, and many are former agency staff with the same skills. What a freelancer usually lacks is the bench for complex implementations - custom feeds, API integrations - that need more than one pair of hands.
I've seen merchants with $5k monthly spend pay $1k in management fees and still see positive ROAS. The test is whether the manager's fee is covered by the improvement in performance.
Where the PPC budget leaks
The biggest mistake is using broad match keywords without a solid negative keyword list. In many accounts, 20-30% of spend goes to irrelevant clicks. Weekly review of search terms is the minimum.
Device bids are the next one. Over 60% of ecommerce traffic is mobile, yet many advertisers never adjust bids by device. A -20% mobile adjustment looks prudent until the data shows mobile converting at much the same rate as desktop, which is why the adjustment gets set from a device report rather than from instinct.
Then there's Maximize Conversions running without a target CPA. Google will spend the entire budget regardless of return, so a target CPA or ROAS goes in even if it's loose. I've seen daily budgets exhausted in two hours that way, with heavy spend and mediocre returns.
How to evaluate a PPC service provider
Ask for a specific proposal. They should be able to describe what they'll do in the first 30 days: account audit, feed cleanup, campaign restructuring. Beware of those who promise 'proprietary algorithms' or 'AI magic' without explaining the logic.
Check their reporting: do they show data you can act on, or just vanity metrics like impressions? A good report includes CPA, ROAS, conversion rate, and impression share - plus changes made and next steps.
Talk to two or three providers. Compare their audit findings before you sign. If all three identify the same wasted spend, you know which fixes come first. If they disagree, you'll learn who digs deeper.
FAQ
How much does ecommerce PPC management cost?
Setup fees range from $1,000 to $5,000. Monthly management is typically 10-20% of ad spend or a flat $500-$3,000 per month. Some agencies offer performance-based pricing, but beware of conflicts of interest with spend-based models.
What ROAS should I expect?
ROAS varies by channel and product margin. Google Shopping averages 2.5-5x, Amazon 3-8x, Facebook 1.5-3x. A 5x ROAS on a 20% margin product means break-even. Always set targets based on your profit margins.
Do I need a separate agency for Amazon?
Not necessarily, but Amazon PPC requires different skills. Many general ecommerce agencies handle both, but if your Amazon spend exceeds $15k/month, a dedicated Amazon specialist often pays off. Check their track record on Amazon specifically.
How long until I see results?
Initial results appear in 2-4 weeks as the learning phase completes. But meaningful optimization (higher ROAS, lower CPA) takes 2-3 months. Seasonal businesses may need multiple cycles to see patterns. Don't judge after one month.
Should I switch from manual to automated bidding?
Automated bidding like Target ROAS works well once you have 30+ conversions per campaign per month. For smaller accounts, manual CPC often performs better. Test both and compare over 30 days. Never switch all campaigns at once.
What's the difference between PPC and PLA?
PPC (pay-per-click) includes all ad types. PLA (Product Listing Ads) is a subset of PPC - the image-and-price ads on Google Shopping. When people say 'ecommerce PPC,' they usually mean Google Shopping plus Amazon. PLA is just the visual format.
