What is Facebook Ads?

Facebook Ads

Facebook Ads is Meta’s paid advertising platform - the system that lets advertisers run paid campaigns across Facebook, Instagram, Messenger, WhatsApp, and the broader Audience Network. One of the two dominant digital advertising platforms (alongside Google Ads), with roughly $135 billion in annual ad revenue across Meta’s properties as of 2024.

The platform’s targeting capability used to be its dominant moat. Privacy changes (iOS App Tracking Transparency in 2021, broader cookie deprecation) have meaningfully eroded that moat. Still strong; no longer the obvious top choice it was in 2018.

What Facebook Ads actually optimises for

Three campaign objective tiers:

Awareness objectives. Reach, brand awareness, video views. Pay to be seen. Useful for upper-funnel campaigns where direct response isn’t the goal. Often misjudged with click-based metrics.

Consideration objectives. Traffic, engagement, app installs, video views with intent. Pay for actions short of conversion. The middle tier where most middle-funnel work lives.

Conversion objectives. Conversions, catalog sales, store traffic. Pay for actual business outcomes. The Meta Pixel (or its server-side equivalent, Conversions API) tracks conversions back to ad exposures and lets the system optimise toward more of them.

Why Facebook Ads still works for some advertisers and not others

Three patterns:

Visual-product DTC brands win. Beauty, fashion, home goods, food, fitness - categories where the product looks good in a feed and the buying decision is reasonably impulsive. Facebook and Instagram remain among the strongest channels.

B2B mostly underperforms. Especially long-cycle, high-consideration B2B where buyers research extensively before committing. The behavioural targeting that made Facebook strong here in 2017 has weakened, and LinkedIn does this job better despite higher CPMs.

Local services depend on geography. Strong in dense urban markets where the audience is large enough to find via Meta’s targeting. Weaker in sparse rural markets where Google search captures most local intent.

What kills Facebook Ads campaigns

Three patterns I see consistently:

Wrong objective for the goal. Running a “traffic” campaign and hoping for purchases. The system optimises for the objective you set. Set “conversions” and feed it real conversion data via the Pixel or CAPI, or it won’t optimise toward what you actually want.

Creative fatigue without creative refresh cycles. The same ad creative running for 6+ weeks degrades in performance as the audience saturates. Top performers refresh creative every 2-4 weeks even when the previous creative was winning.

Ignoring iOS attribution loss. Post-ATT, a meaningful chunk of iOS conversions are no longer attributable to Facebook ads in the platform’s reporting. Brands that judge channel performance only on in-platform reporting consistently undercount Facebook’s contribution.

An example

A DTC supplement brand had been running Facebook ads at $5K/month for two years with reported ROAS of 1.4x - losing money on the channel by the platform’s own numbers. They had been about to cut the channel entirely.

The audit included server-side conversion tracking (Conversions API plus a third-party attribution model that could see post-iOS journeys). True ROAS turned out to be 2.8x - Facebook had been driving substantially more conversions than its own reporting credited it with, particularly on iOS.

They kept Facebook as a channel and actually increased spend by 60%. With proper measurement, the channel was profitable and the additional spend continued to scale at similar economics until they hit audience saturation about three months later.

The decision to kill Facebook would have been correct based on the data they had. The data they had was wrong.
