Meta Ads is the umbrella term for ads delivered across Meta's apps and networks, including Facebook, Instagram, Threads, Messenger, and Audience Network. Sometimes called "Facebook ads" or "Instagram ads," these are all part of the same Meta Ads system and are published through the same interface, Meta Ads Manager. A key feature is the ability to deliver multiple formats, including images, videos, and carousels, across these placements.
This article covers the full picture of Meta Ads: ad types and placements, costs and billing, getting started from account creation to publishing, ad specifications, advertising on Instagram, measurement, targeting, and ways to improve performance. Detailed procedures and specifications for each topic are covered in separate articles, so follow the links in the text to find the information you need.
One reason many businesses use Meta Ads is the wide choice of placements and creative options. You can choose formats such as photos and videos and reach people on services they use every day, including Facebook and Instagram. This makes Meta Ads useful for a broad range of objectives, from building brand awareness to generating specific results such as purchases and inquiries.
Meta Ads types and placements: Facebook, Instagram, Threads, Messenger, and Audience Network
Meta Ads can run across five placements operated by Meta. Advertisers can select placements individually based on their campaign objectives and budgets, or let Meta's system optimize allocation automatically. Unlike search ads, which are triggered by search keywords, Meta Ads are delivered based on users' characteristics, interests, and behavior. This allows you to reach potential customers who are not yet actively searching for your products or services.
Placement | Key features |
|---|---|
Ads appear in Feed, Stories, Reels, Marketplace, and other placements. Used by a broad range of people across age groups. | |
Ads appear in Feed, Stories, Reels, Explore, and other placements. Well suited to visual messaging through images and videos. | |
Threads | Ads appear in the feed. The newest placement, opened to eligible advertisers worldwide in April 2025. |
Messenger | Ads appear in the inbox and Stories. Easy to combine with messaging flows for inquiries and customer service. |
Audience Network | A network that delivers ads to partner apps and websites outside Meta. Extends reach beyond Facebook and Instagram. |
Several creative formats are also available.
Image ad: A simple format that uses a single still image
Video ad: A format well suited to storytelling and demonstrations
Carousel ad: A format that displays multiple images or videos side by side
Formats for Stories and Reels: Full-screen formats displayed vertically
The best aspect ratio and duration vary by placement, even for the same ad. Preparing multiple formats makes it easier to advertise across placements. If you are unsure which placements to choose, one option is "Advantage+ placements," which lets Meta's system automatically allocate your budget to placements likely to deliver results, instead of manually narrowing the selection. Specific dimensions and safe zones for each placement are covered below.
Meta Ads costs and billing: Auctions, CPC, and CPM
Meta Ads costs are determined through an auction rather than a fixed fee. Advertisers choose the actions they are charged for, such as clicks or views (impressions), based on their campaign objectives and set bids for those actions. Charging per 1,000 impressions is called CPM (Cost Per Mille), and charging per click is called CPC (Cost Per Click). Both are basic Meta Ads pricing models. Which to choose depends on your campaign objective: CPM is generally the starting point for building awareness, while CPC is the starting point when driving traffic to your website is the priority. For details on calculating and interpreting CPM, see our explanation of CPM (cost per 1,000 impressions). For a breakdown of costs focused on Instagram placements and steps to work backward to a budget, see Instagram ad costs and how to set your budget.
The ads that are actually delivered are not determined by bid size alone. Meta's official developer documentation explains that an "effective bid" is calculated by combining the bid amount and bidding strategy with the likelihood of achieving the selected optimization goal, and this determines ranking in the auction (Meta for Developers, "Bidding Overview"). Depending on the bidding strategy, the amount you actually pay is generally equal to or less than the maximum bid you set.
It is also important to understand the levels at which you can set budgets. Budgets can be set at either the campaign level or the ad set level. You choose between "Daily budget," which sets a limit per day, and "Lifetime Budget," which sets a limit for the entire delivery period. In general, a Lifetime Budget suits campaigns that run for a limited period, while a Daily budget suits ongoing campaigns.
The main factors that affect costs include competition for your target audience, the season, day of the week and time of day when ads run, creative quality, and the relevance of the destination page to the ad. Appropriate spending levels vary widely by industry and product. A practical approach is to start with a small test budget and adjust it using your own performance data, rather than rely on a single market benchmark.
Getting started with Meta Ads: From account setup to campaign launch
There are three main things to prepare before you start using Meta Ads.
Business portfolio: A container for managing pages and ad accounts together at the company or team level
Ad account: The account where ad spending is incurred and campaigns are created
Payment Method: Register a way to pay for ads, such as a credit card
You can set these up through Meta Business Suite, Meta's business management tool. An ad account's country, currency, and time zone are difficult to change after creation, so check them beforehand. Depending on your usage, you may also be asked to complete business verification to confirm that your business exists. If requested, follow the instructions to prepare the required documents, such as business registration information.
Once these preparations are complete, you create campaigns in Meta Ads Manager. In this interface, you organize delivery in three levels: campaign (the objective you want to achieve), ad set (who sees your ads, when, and where), and ad (the images, videos, and text people actually see). For the campaign objective, choose the category closest to your business goal from six options: Awareness, Traffic, Engagement, Leads, App Promotion, and Sales (Meta for Developers, "Campaign, Ad Set and Ad").

The image above shows the Meta Ads Manager interface. For specific steps to create a business portfolio and ad account, navigate the interface, build a campaign, and handle common issues such as rejected ads and account restrictions, see "How to use Meta Ads Manager." Reviewing it can help if you are setting up your first account or have just taken over ad operations.
You can also submit Meta Ads through Cascade's Ad Posting and Editing. You can plan campaigns, submit ads, and change budgets and targeting after launch, all in one interface. To view performance alongside other platforms such as Google Ads, Yahoo! JAPAN Ads, and TikTok Ads, use Ad Analytics + Automated Reports.
Ad specifications and preparing creative
An ad consists of multiple elements: visual assets such as images and videos, a headline, primary text, a description, and a call-to-action (CTA) button such as "Learn more" or "Buy now." The combination of text elements can change the impression just as much as the visuals, so consider both together when preparing creative.
Recommended dimensions and aspect ratios for Meta Ads creative vary by placement. If you use the same image or video unchanged in placements that primarily display landscape or square content, such as Facebook feed, and in vertical, full-screen placements such as Stories and Reels, important elements may be cropped. For campaigns running across multiple placements, preparing vertical assets alongside a square version can help prevent display problems.
To pass ad review, check that your text, images, and videos do not make exaggerated or misleading claims and that your ad messaging matches the content of the linked Landing Page. Recommended dimensions by placement, safe zone guidelines, and detailed requirements for file formats and sizes are covered in "Meta Ads dimensions and safe zones." Reviewing these before submitting ads can help prevent review rejections and display problems.
Advertising on Instagram
Instagram is one of the placements managed through Meta Ads Manager, and ads published there are sometimes called "Instagram ads." You can select Instagram as a placement within the same interface and campaign structure used for Facebook ads. If you already run Facebook ads, you can try Instagram delivery without substantial additional setup.
Instagram placements, including Feed, Stories, Reels, and Explore, all center on a visual experience. Reels and Stories in particular display content vertically across the full screen, so the appeal of the images and videos themselves often has a greater impact on results than text. These placements are well suited to showing a brand's visual identity or products in use, and often call for a different approach to creative than Facebook feed.
Creative requirements also differ among Instagram placements. People tend to spend relatively longer in the feed, making it a good fit for information-rich creative, while Reels and Stories tend to favor a brisk pace designed for brief viewing. For instructions on connecting your Instagram account to a business portfolio, steps specific to publishing Instagram ads, and practical tips for Feed, Stories, and Reels, see "How to run Instagram ads."
How measurement works: Meta pixel and Conversions API
No matter how much you refine creative and placements, you cannot judge which tactics work unless you accurately measure the actions people take on your website after engaging with an ad. The foundation of this measurement is the Meta pixel. This code measures website actions such as purchases and inquiries and sends them to the Meta Ads management system. It is used not only to measure conversions, but also to retarget website visitors and reach new users similar to existing customers. For details on how it works and how to set it up, see "What is the Meta pixel?"
In recent years, iOS App Tracking Transparency (ATT), which requires apps to ask users for permission to track them, and tighter browser restrictions on cookies have made measurement gaps more likely when relying on the browser-based Meta pixel alone. The Conversions API (CAPI) helps fill these gaps. It is a server-side mechanism that sends data directly from an advertiser's web server to Meta's systems. Using the Meta pixel and Conversions API together, with shared Event IDs to remove duplicates, is now the basic approach to measurement in Meta Ads.
Approaches to targeting: Core, custom, similar, and Advantage+ audiences
Meta Ads targeting is broadly based on three concepts: Core audience, Custom Audience, and Similar audience.
Audience type | Overview |
|---|---|
Core audience | Targeting based on data Meta holds about users, such as age, location, gender, and interests |
Custom Audience | An audience created from your own data, such as customer lists, website visitors, and app users |
Similar audience | A mechanism in which Meta's system uses a Custom Audience as a "seed" to find new users with similar characteristics |
Meta's official developer documentation describes Custom Audience as a feature that lets you "create your own audiences from multiple sources, including email addresses, phone numbers, and behavioral data from websites and apps" (Meta for Developers, "Custom Audiences"). It is generally used to reengage people who have already interacted with your business. The similarity setting for a Similar audience ranges from 1% (the most similar group) to 20% (a broader group). The guidance is to test a narrow range first, then expand it (Meta for Developers, "Lookalike Audiences"). Combined with interest- and behavior-based targeting for a Core audience, you can also exclude specific segments. A common use is to exclude customers who have already purchased from campaigns aimed at acquiring new customers.
Meta also offers "Advantage+ audience," an AI-powered mechanism for expanding targeting. It keeps mandatory constraints set by the advertiser, such as age, location, and language, while extending delivery beyond manual settings to users Meta's system considers likely to generate results. The specific scope of expansion and algorithm details are not public. Test the feature in your own account to assess its effectiveness, and check the latest specifications in Meta Business Help Center's "About Advantage+ audience".
Improving ad operations and using AI
Managing Meta Ads is part of the broader work of ad operations, which shares common practices with other programmatic (auction-based) ads such as Google Ads. For the fundamentals of ad operations across platforms, see "What are ad operations?" Two challenges often highlighted in the context of Meta Ads are creative fatigue and budget allocation.
Creative fatigue occurs when the same ad is shown repeatedly to the same users and response rates gradually fall. It often appears as rising CPM or falling CTR. Basic countermeasures include preparing several creative variations and rotating them regularly, as well as revisiting messaging and formats based on performance. Just after ads launch, or after major changes to budgets or targeting, there is also a "learning phase," an adjustment period before results stabilize. Frequent setting changes during this period can restart learning, so it is generally best to monitor performance until enough data has accumulated before making decisions.
Budget allocation also requires ongoing decisions throughout ad operations. Performance often differs across campaigns, ad sets, and placements, requiring repeated adjustments to shift spending toward stronger performers and away from weaker ones. If you run ads on other platforms alongside Meta Ads, deciding how to allocate budgets across platforms and checking their separate interfaces can add substantially to the workload.
Cascade, an AI agent for ad management, offers features that reduce this operational workload. It can generate image and video ad creative, optimize budget allocation based on daily performance, and manage multiple ad platforms, including Meta Ads, Google Ads, and TikTok Ads, from a single interface. It is one option if you want to centralize operations across platforms, including Meta Ads. It is worth considering if you want to reduce the work of manually refreshing creative and adjusting budgets each time. You can find feature details on Cascade's official website.

FAQ
What is the difference between Meta Ads and Facebook ads?
Meta Ads and Facebook ads are not separate, competing systems. Meta Ads refers to Meta's entire advertising service, including Facebook, Instagram, Threads, Messenger, and Audience Network. Facebook ads refers specifically to ads placed on Facebook within that service. In practice, advertisers generally configure multiple placements, such as Facebook and Instagram, together in the same Meta Ads Manager.
Can I start with a small budget?
Meta Ads costs are determined through a bidding auction, so there is no single fixed minimum ad spend. A common approach is to start with a small test budget and gradually increase it while reviewing results. However, if the budget is too small, you may not collect enough delivery data for AI optimization to work effectively. Start testing with an amount you can afford, consider whether to use a Daily budget or Lifetime Budget, and adjust based on results.
Do I need separate contracts for Instagram ads and Facebook ads?
No separate contracts are needed. Instagram ads and Facebook ads can both be published through the same Meta Ads Manager and ad account. You can select both Facebook and Instagram as placements within a single campaign. You do need to connect your Instagram account to your business portfolio, but ad review and payment procedures are not separate for each placement.
Summary
Meta Ads is the umbrella term for Meta's advertising service, which supports multiple formats, including images, videos, and carousels, across five placements: Facebook, Instagram, Threads, Messenger, and Audience Network. Facebook ads and Instagram ads are part of this system and are published through the same Meta Ads Manager. Costs are determined by auction under CPC and CPM billing models and vary with competition and creative quality.
The overall setup process starts with preparing a business portfolio and ad account, then creating a campaign in Meta Ads Manager. Ad specifications, advertising on Instagram, measurement using the Meta pixel and Conversions API, and targeting approaches are covered in more detail in the linked articles. Refer to the sections relevant to your needs.
The current basic approach to targeting centers on the three audience types, Core audience, Custom Audience, and Similar audience, while also considering AI-based expansion features such as Advantage+ audience. Interface specifications and policies are updated regularly. When you are unsure how to proceed, check the latest information in Meta Business Help Center and update your operating practices at a manageable pace.
