Facebook Ads

Facebook Ads run through Meta Ads Manager, the same interface and account structure used for Instagram, Messenger, and Audience Network placements, and in most modern campaign setups Meta's Advantage+ placements default to serving your ad across all eligible surfaces - Facebook feed, Instagram feed, Stories, Reels, Marketplace, and Audience Network - rather than a single chosen placement, unless the advertiser manually restricts placements. This is different from Google Ads, where campaign type largely determines which inventory you buy; on Meta, one campaign objective and one ad set can span multiple visually distinct placements simultaneously, and the delivery system decides how to split budget across them based on where it expects the best result for your stated objective.

Targeting works primarily on interest, behavior, and connection signals layered onto Meta's Advantage+ audience tools, plus first-party data you upload through Customer Match-style Custom Audiences and Lookalike Audiences built from them - not keywords, since there is no search query to key off the way Google Search has. Since Meta removed detailed-targeting exclusions in March 2025, advertisers lost the ability to exclude specific interest or behavior categories from an audience the way they once could, which pushed more of the audience-refinement work onto Custom Audience exclusions (uploaded lists or pixel-based audiences you actively exclude) instead of interest-based exclusions - a workflow change that trips up practitioners who learned the platform before the change.

The setting it interacts with most is the objective chosen at campaign creation, because Meta's delivery algorithm optimizes toward whatever the objective specifies - Sales, Leads, Traffic, Awareness, Engagement - and will find the cheapest way to produce that specific outcome even if it means serving an ad in a placement or to an audience segment the advertiser did not explicitly picture. Choosing Traffic when the actual goal is Sales is a common early mistake: the algorithm will happily deliver cheap link clicks from people unlikely to buy, because clicks were the stated goal, and the resulting CPC will look great while the campaign fails to move the metric that actually matters to the business.

It matters most for businesses creating or triggering demand for something people are not actively searching for yet - a new product, an impulse or discovery-driven purchase, a visually differentiated offer - because targeting rests on who someone is and what they do rather than what they typed. It matters less as a channel for capturing already-explicit demand the way Google Search does; someone actively searching "emergency plumber near me" is far better served by a Search ad than a Facebook feed ad, since Facebook has no equivalent real-time expressed-intent signal to match against. The common misunderstanding practitioners bring from Search is expecting Facebook Ads to behave like a keyword channel - tightly controllable audience inputs producing predictable, query-matched traffic - when in practice creative quality and the objective setting drive far more of the outcome on Meta than audience selection alone does.

In reporting, iOS's App Tracking Transparency framework continues to undercount pixel-only, browser-based conversion attribution for users who have opted out of tracking, which means Meta's reported conversions and the platform's own modeled or estimated results can understate or misattribute some real conversions, particularly on iOS-heavy audiences. Pairing the pixel with the Conversions API (server-side event forwarding) meaningfully closes that gap and is the standard fix rather than something to work around manually. Also read results by objective and placement breakdown rather than blended account totals, since an awareness-objective campaign and a sales-objective campaign optimizing for entirely different outcomes will produce entirely different, non-comparable cost and conversion profiles even when they are running to similar audiences.
