Ecommerce, short for electronic commerce, is the buying and selling of goods or services over the internet. It covers an online store, a marketplace listing and a subscription box. For many online stores, Meta ads are a main way to find new shoppers.
Common ecommerce models
| Model | How it works | Ad angle |
|---|---|---|
| Direct to consumer (DTC) | A brand sells its own products from its own site | Ads carry the whole journey, from discovery to purchase |
| Marketplace seller | Sells through a platform such as Amazon or Etsy | Ads may send traffic to the listing or to a separate store |
| Dropshipping | The store takes the order and a supplier ships it | Thin margins, so costs per sale matter a great deal |
| Subscription | Customers pay on a repeat schedule | Value comes from repeat orders, not one sale |
Social commerce is a related model where the sale starts on a social platform.

- Conversion rate. The share of visitors who buy.
- Average order value. Revenue divided by orders.
- Customer acquisition cost. What it costs to win a new buyer.
- Return on ad spend. Revenue from ads divided by ad spend.
- Repeat purchase rate. How many customers come back.
A store needs ROAS to stay above its break-even point, which depends on margins. The break-even ROAS calculator works it out from your costs.
How Meta ads fit an ecommerce business
- Install tracking. The Meta Pixel and the Conversions API report views, add to carts and purchases, so Meta can learn who buys.
- Upload a catalog. It holds the products and prices.
- Reach new people. Prospecting ads and sales campaigns find shoppers who haven't visited yet.
- Bring visitors back. Product ads show people the items they looked at, using the catalog and their activity.
- Read the results. Compare spend with revenue, cost per purchase and the share of buyers who are new.
Ecommerce also has costs that ads never show: shipping, returns, payment fees and product cost. Keep them in view when you read ad results, because they decide whether a sale makes money. A store that tracks them can set a target ROAS with confidence instead of guessing.
Common mistakes
- Scaling before the basics work. Weak product pages waste even good traffic.
- Looking only at ROAS. A good ROAS can still lose money after shipping and discounts.
- Missing purchase events. If Meta can't see sales, it can't optimize for them.
- One creative for everything. Different products and audiences need different angles.
Example. A coffee roaster sells 12 ounce bags at $18 and spends $900 on Meta ads in a month. The ads bring 75 orders worth $1,350 in revenue. The ROAS is 1.5 ($1,350 ÷ $900), and the cost per order is $12 ($900 ÷ 75). With $11 of cost to roast and ship each bag, the roaster loses money on a first order. It keeps the ads running only because many buyers subscribe, so the true return comes over several orders.
