Once your products are live, Advertising on ASM is the fastest way to get them in front of more pet parents. This playbook explains exactly how Sponsored ads on American Service Marketplace work — the ad wallet, CPC vs CPM bidding, the fair-rotation auction, budgets, and how to measure return on ad spend (ROAS).
What ASM ads are
ASM ads are Sponsored product placements. Your products appear, clearly labeled as “Sponsored,” inside the same search results and category rows shoppers already browse — plus a promoted spot on your own storefront. Because they look and behave like normal product cards, they feel native rather than intrusive. Get the overview on the Advertise on ASM page, then come back here for the mechanics.
The ad wallet: you only spend what you load
Advertising runs on a dedicated ad wallet, separate from your sales payouts. You top it up with a card, and campaigns draw from that balance. This is the single most important safety feature: you can never spend more than you have funded. When the balance runs low, campaigns pause and you are notified — no surprise bills.
CPC vs CPM — choosing how you pay
American Service Marketplace supports two bidding models, and you can use whichever fits your goal:
- CPC (cost-per-click) — you pay only when a shopper actually clicks your product. Best for driving traffic and sales efficiently, because idle views cost nothing.
- CPM (cost-per-thousand-impressions) — you pay per thousand times your product is shown. Best for visibility and brand awareness, especially for new launches.
Most sellers start with CPC because it ties spend directly to interest. As your brand grows, CPM can help you own visibility in a category.
The fair-rotation auction
ASM does not simply sell the top spot to the highest bidder. Sponsored slots are limited per page and placed at varied positions, and winners are chosen by a weighted lottery that blends your bid with a quality signal (how relevant and engaging your product is). The result is fair rotation: strong, relevant products from many sellers all get genuine exposure, instead of one big spender pinning the top forever.
Practically, that means a sharp listing with good photos, reviews and an accurate category can win impressions without the highest bid — so the fundamentals from our selling guide directly improve your ad performance.
Budgets and control
Every campaign gives you hard guardrails:
- Daily budget — caps how much a campaign can spend in a day.
- Total budget — caps the campaign's lifetime spend.
- Auto-pause — campaigns stop automatically when budgets are hit or the wallet is low.
- Pause/resume anytime — you are always in control from your dashboard.
Measuring ROAS
The point of advertising is profit, not just clicks. Each campaign has a full analytics view showing impressions, clicks, click-through rate (CTR), spend, conversions and ROAS (return on ad spend) over time. ROAS tells you how much revenue each advertising dollar produced — the single number that says whether to scale a campaign or rework it.
Tips that actually work
- Advertise your best listings — strong photos and reviews convert ad traffic far better.
- Start with CPC and a modest daily budget to learn what converts.
- Use coupons together with ads to lift conversion on the traffic you pay for.
- Watch CTR and ROAS, not just spend — optimize toward profit.
- Refresh creative — update images and titles on under-performers before giving up.
