Where Ads Appear

Meta sells placements across its own apps and a network of third-party apps and websites called the Audience Network. Placements include feeds, Stories, Reels, in-stream video, search results, Messenger inbox and more. You can let Meta choose placements automatically or pick them by hand, which is covered in the Placements guide.

The Auction

Every time there's a chance to show an ad, Meta runs an auction among the eligible ads. The highest bidder doesn't always win. Meta combines three factors into a total value: your bid, the estimated action rate (how likely the person is to take the action you're optimizing for) and ad quality (signals about relevance and user feedback).

That's why a relevant ad with a lower bid can beat a less relevant ad with a higher bid, and why creative quality has such a strong effect on your costs.

The Delivery System

Once an ad starts winning auctions, the delivery system decides how to spend your budget over time and across the audience. It works from the optimization goal you set at the ad set level (purchases, leads or link clicks, for example) and learns from results as they come in. Early in an ad set's life the system is in a learning phase, and results are less stable while that lasts.

The Tools

Ads Manager is where you create, edit and report on campaigns. Meta Business Suite combines organic posting, your inbox and basic ad tools. Events Manager handles data sources such as the Meta Pixel and the Conversions API. A Business Portfolio (formerly Business Manager) holds the assets and permissions behind all of them.

Putting the Pieces Together

A typical flow looks like this. You create a Business Portfolio and an ad account, install the Meta Pixel and the Conversions API so Meta can see what happens on your website, build a campaign in Ads Manager with an objective, an audience and creative, then read the results in Ads Manager reporting. Each of these steps has its own guide in this reading order.

Putting This to Work

The practical takeaway for you is that creative quality and accurate tracking affect your costs as much as your budget does. A better ad performs better, and it's also cheaper to show.

Key Facts

• Meta has been renaming Facebook Ads tools and assets under the Meta brand from 2021 onward, so older guides may use Facebook names for the same products.
• Ad costs are driven by competition, audience and creative quality, which is why there's no single price for a Meta ad.
