What is the method of buying Facebook ads?

Facebook has become a powerhouse in digital advertising, offering businesses of all sizes access to more than 2.8 billion monthly active users. One of the most important decisions when setting up a campaign is choosing the right ad buying method If you’re unfamiliar with Facebook ads or trying to figure out which buying method is best for your goals, this article will break it down.
What is Facebook advertising?
Before diving into the buying process, it’s essential to understand what Facebook ads are. Facebook Ads are paid messages that businesses use to promote their products, services, or events to targeted users on Facebook and related platforms such as Instagram, Messenger, and Audience Network.
You can run different types of ads on Facebook, including:
Image Ads (single image with text)
Video ads (short or long videos)
Carousel ads (multiple images or videos users can scroll through)
Slideshow ads (looping images similar to videos)
Collection ads (multiple product displays)
Now that we’ve covered the basics of what Facebook ads are, let’s get to how you can buy these ads
How to buy Facebook ads explained

Facebook offers two primary methods for buying ads: auctions and reach and frequency. Each method has advantages and disadvantages and choosing the right one depends on your campaign objectives, budget, and the type of audience you are targeting.
How to Buy an Auction
The auction method is by far the most popular buying option. When you create a campaign using this method, your ad is placed in a competitive bidding environment where you bid against other advertisers for placement.
How the auction process works
Whenever a user has an opportunity to be shown an ad, Facebook’s algorithm conducts an auction to determine which ad will be shown. The winner of this auction is not necessarily the highest bidder—Facebook takes into account several factors, including:
Bid Amount (how much you are willing to pay)

Ad quality and relevance (are your ads attractive and well-received by users?)
Estimated Action Rate (How likely is a user to take the desired action?)
This system ensures that high-quality ads are prioritized and helps advertisers get the most value for their budget.
Factors Affecting Auction Success
To be successful in Facebook auctions, you need to balance several factors:
Bid – You can manually set a bid cap or let Facebook adjust your bid based on your goals.
Relevance – If your ad is relevant and well-received, it is more likely to be shown to Facebook users.
Ad Quality – High-quality creative content will improve your chances of winning an auction.
Approaches to buying reach and frequency
The reach and frequency approach is ideal for advertisers who want more predictable results Instead of competing in an auction, you can lock in a certain number of impressions at a certain price by reaching your target audience within a certain period.
When to use reach and frequency
This method is best suited for promoting brand awareness or when you have a broad target audience. This guarantees that you will reach a certain number of people (your “reach”) at a certain frequency (how often they see your ad). This can be useful for businesses looking for steady, reliable exposure.
Reach and frequency are key benefits of buying
Predictability – You know exactly how many people your ad will reach and how often they will see it.
Control – You can control the frequency cap, ensuring your audience isn’t overwhelmed by ads.
Fixed cost – Since you are not bidding in an auction, the cost of impressions remains constant.
The key difference between auction and reach and frequency
Flexibility: The auction method offers more flexibility to adjust your budget and set goals on the go, while reach and frequency are more rigid but predictable.
Budget Considerations: If you have a tight budget or need to adapt mid-campaign, the auction method is more suitable. Reach and frequency are often better for larger campaigns with a set budget and a clear goal.
Control vs. predictability: The auction system gives you more control over how much you spend and who sees your ads, while reach and frequency give more predictable results.
How to Choose the Right Buying Method for Your Business
Choosing between auction and reach and frequency methods depends on several factors:
Campaign goals: If you’re focused on conversions or specific actions (like clicks or app installs), the auction method is your best bet. For brand awareness, reach and frequency can be more effective.
Audience size: Reach and frequency work best for large, broad audiences. For more niche targeting, auctions are more efficient.
Budget: Smaller budgets perform better in auctions, while larger campaigns with fixed budgets can benefit from the reach and frequency approach.
Setting up your campaign using the auction method
If you decide to use the auction method, here is a step-by-step guide:
Create your campaign in Facebook Ads Manager and choose your
campaign objective (traffic, conversions, etc.).
Set your budget—You can choose a daily or lifetime budget.
Target your audience—use demographic filters, interests, behaviors, or custom audiences.
Set your bid strategy—choose from options like minimum cost, cost cap, or bid cap.
Launch your ad and monitor performance.
Setting up your campaign using reach and frequency methods
For reach and frequency:
Choose reach and frequency as your buying method in Ads Manager.
Set your campaign goals, audience size, and desired frequency.
Set your budget and schedule by specifying how long your campaign will run.
Run your ads by making sure to monitor frequency to avoid ad fatigue.
Bidding Strategy on Facebook Ads
Facebook offers several bidding strategies that can influence how you buy:
Minimum cost (default, ideal for maximum results)
Cost cap (keeps costs under control)
Bid cap (sets a limit on how much you are willing to bid)
Ad placement options
You can either let Facebook handle the placement automatically or choose manually. Automatic placement gives Facebook more flexibility, which can reduce costs, while manual placement gives you more control over where your ads appear.
Optimizing Facebook ad performance
To ensure your campaign is successful, regularly analyze performance metrics like click-through rate (CTR) and cost-per-click (CPC). A/B testing different creatives, placements or audiences can significantly improve results.
Common Mistakes to Avoid When Buying Facebook Ads
Avoiding these common mistakes will ensure more efficient ad spend:
Overbidding or underbidding – Striking the right balance in your bidding strategy is crucial.
Misunderstanding Targeting – Make sure your target audience is neither too broad nor too narrow.
Ignoring Frequency Caps – In reach and frequency campaigns, don’t bombard users with ads.
Improved purchasing strategy
For more advanced users, techniques like budget pacing (adjusting your budget throughout the campaign) and ad delivery optimization (choosing objectives like link clicks or landing page views) can improve your campaign’s efficiency.
Conclusion
Choosing the right buying method for your Facebook ads can have a huge impact on the success of your campaign. Whether you go with auctions or reach and frequency, it all depends on your objectives, budget, and audience size. Understanding these options will help you maximize your return on investment and ensure your ads reach the right people at the right time.
