Facebook ads for ecommerce, run on autopilot

The average Facebook ad click runs about $1.72 in 2026 and CPMs sit between roughly $8 and $15, with a median near $13.48. What matters more for a store is cost per purchase: the 2026 median across ecommerce is about $38, ranging from near $30 in lifestyle and apparel to close to $50 in electronics, where competition and price sensitivity are higher. Apparel and food tend to carry the cheapest clicks; considered, higher-ticket categories cost more per sale.

Most small and mid-size stores start Meta at $1,500 to $10,000 a month and scale from there once the account is profitable. The right number is set by your margin and target cost per purchase, not by a flat rule. Work backward from your product economics with the advertising budget calculator, and see the wider tool landscape on our AI ads for ecommerce page.

A good Facebook ROAS for ecommerce is any figure above your break-even, which is set by your gross margin: a store running a 50% margin breaks even at 2.0x, a 40% margin at 2.5x, and a 33% margin at 3.0x. The 2026 ecommerce median is about 1.93x, so many brands run blended Meta ROAS in the 2x to 4x range, with prospecting campaigns lower and retargeting higher. Chasing a single headline ROAS number usually means underspending on profitable prospecting.

Blended ROAS across the whole account matters more than any one campaign, because cold prospecting that looks unprofitable in isolation is often what feeds the cheap retargeting sales. AdBot optimizes toward your target cost per purchase across the funnel rather than flattering one campaign, the same engine behind our automated Facebook ads and AI ads for Shopify pages.

Run both if you can, because they do different jobs. Google Shopping and Search capture people already looking for your product and usually convert at a higher rate, while Facebook and Instagram generate demand among people who did not know they wanted it yet. Most stores spending $5,000 or more a month get the best result from a coordinated funnel: Meta creates the demand and builds retargeting pools, Google captures the searches that demand produces.

The split depends on your product. Impulse and visually driven products lean Meta; considered, search-heavy purchases lean Google. We break the tradeoff down in Facebook ads vs Google ads for ecommerce and Google Ads vs Facebook Ads. AdBot runs both channels from one flat fee, so you are not choosing on the basis of who manages it. It does not run LinkedIn, Microsoft, or Amazon ads, so keep that in mind if those are core to your plan.
