If you are running or planning your first Facebook ad campaign, you will quickly run into three tools with similar names: Ads Manager, Business Manager, and the Ad Library. This guide explains what each one does, how they fit together, and how much advertising on Facebook actually costs.
What is Facebook Ads Manager?
Facebook Ads Manager is the dashboard where you create, run and measure ad campaigns across Facebook, Instagram, Messenger and Meta’s wider Audience Network. It is where the actual advertising work happens: choosing an objective, defining an audience, uploading creative, setting a budget, and reviewing performance.
Every campaign in Ads Manager follows the same three-level structure. A campaign sets your overall objective, such as traffic, engagement or conversions. Inside each campaign, one or more ad sets define your audience, placements, budget and schedule. Inside each ad set, one or more ads contain the actual creative your audience sees, the image or video, headline and text.
This structure matters because it lets you test different audiences or creative without rebuilding a campaign from scratch. A common approach is to keep one ad set stable while testing several ad variations inside it, then keep the best performer and pause the rest.
What is Facebook Business Manager?
Facebook Business Manager, now part of Meta Business Suite, is the account management layer that sits above Ads Manager. Instead of running ads from a personal profile, Business Manager lets a company organize its Pages, ad accounts, product catalogs and team members in one central place.
The main reason businesses set up Business Manager is access control. You can add team members or agencies with specific permission levels, full access, ad creation only, or analytics only, without ever sharing a personal Facebook password. If someone leaves the company, you simply remove their access in Business Manager rather than changing a shared login.
To get started, go to business.facebook.com and create an account using a business email address, separate from your personal Facebook login. From there you add your Page, connect or create an ad account, and invite team members.
What is the Facebook Ad Library?
The Facebook Ad Library is a free, public tool that shows every ad currently or recently running on Facebook and Instagram, along with which Page is paying for it. You do not need to be logged in or have an ad account to use it.
Two groups use it most. Marketers use the Ad Library to research what competitors are running, which creative formats they favor, and how often they refresh their ads. Journalists, researchers and the general public use it to check political and social issue advertising, which Meta is legally required to make transparent, including how much was spent and who the audience was.
To use it, visit Meta’s Ad Library website, choose a country, and search by Page name, keyword, or advertiser. It is one of the fastest ways to see real, live examples of ad creative in your industry before building your own campaign.
How much does it cost to advertise on Facebook?
Facebook ads use an auction system, so there is no fixed price list. Instead, cost depends on how many advertisers are competing for the same audience, how relevant your ad is predicted to be, your bid strategy, and the time of year, costs typically rise around major shopping periods like the end-of-year holidays.
As a general starting point, many small businesses begin testing with a daily budget in the range of a few dollars to a few tens of dollars per ad set, then scale up campaigns that show a positive return. Facebook reports cost per result (cost per click, per purchase, and so on) directly inside Ads Manager, which is the number to watch rather than total spend alone.
Ads Manager versus Business Manager versus Ad Library, in short
- Ads Manager is where you build and run campaigns.
- Business Manager is where you manage the account, Pages, and who has access.
- Ad Library is a free public tool for researching any advertiser’s live ads.
Getting started, step by step
- Create a Business Manager account at business.facebook.com using a business email.
- Add or create your Facebook Page inside Business Manager.
- Create an ad account and add a payment method.
- Open Ads Manager and create your first campaign, choosing an objective that matches your goal (traffic, leads or sales).
- Define your audience, set a modest daily budget while testing, and upload your ad creative.
- Before launching, search the Ad Library for a few competitors to see what creative styles are already working in your space.
Frequently asked questions
Do I need Business Manager to run ads?
Technically no, you can run limited ads by boosting a post directly from a personal Page, but Business Manager is strongly recommended for anyone running ads regularly or working with a team.
Is the Ad Library free to use?
Yes, it is completely free and does not require a login.
Why did my ad cost more than expected?
Cost per result is driven by auction competition and ad relevance. Narrow, highly competitive audiences and low-quality creative both tend to increase cost.
