Facebook Ads: Auction Vs. Reservation What Is The Difference

Facebook offers two primary ad buying types: Auction and Reservation. While both can be effective, they serve different purposes and work best under different circumstances. The choice between using Auction or Reservation can significantly impact your campaign's reach, cost, and overall effectiveness.

Auction Vs. Reservation Buying Type

Defining Auction And Reservation In Facebook Ad Buying

Navigating the landscape of Facebook advertising requires an understanding of the platform's ad buying mechanisms. Two dominant strategies prevail: Auction and Reservation. Though they share the common goal of helping your ads reach a target audience, they operate on different principles and processes. Let's break down each method:

Auction:

• What is an Auction in Facebook Ads?

  • In an auction, advertisers compete to have their ads shown to a target audience. Unlike traditional auctions, you see on TV, involving the highest bidder taking home the item up for bid, Facebook uses a more complex model. It's not just about how much you're willing to pay, but also how relevant your ad is to the audience and the quality of the ad itself.

• Pricing and Competition:

  • Your bid plays a significant role, but it's one part of the equation. Facebook considers the total value of each ad, which includes three components: the advertiser's bid amount, the ad's estimated action rates (how likely it is for people to engage with your ad), and the ad's quality and relevance. The ad with the highest total value wins the auction.

• Flexibility and Scalability:

  • Auction buying is dynamic and offers flexibility. You're not committed to spend a certain amount, and you can start or stop campaigns at any time. This method is scalable, suitable for any budget, and you only pay for the impressions received.

Reservation:

• What is Reservation Buying?

  • Reservation buying allows you to book ad space in advance at a fixed cost through the use of a Lifetime budget. Unlike auctions, the price doesn't fluctuate based on competition. This method is typically used for campaigns with larger budgets that aim to achieve brand awareness within a specific period, such as product launches or seasonal promotions.

• Fixed Pricing:

  • With reservation, you pay a predetermined price, allowing for more predictable budgeting. You'll know in advance the cost of your campaign and the number of impressions your ads will receive.

• When to Use Reservation:

  • Reservation is ideal when you have a significant budget and specific goals for reach and frequency and want more control. It's often used for campaigns where timing is crucial, and there's a need to guarantee that the ad will be shown during the specified period.

Comparing Campaign Setup For Auction And Reservation Buying

When should you use auction and when should you use reservation? Next we examine the difference between each buying type.

Campaign Objectives:

• Auction:

  • Auction campaigns are versatile, catering to a wide range of Facebook campaign objectives, whether it's driving website traffic, boosting post engagement, or generating leads. The flexibility allows advertisers to pivot strategies quickly based on real-time performance data.

Auction Buying Type

• Reservation:

  • Reservation campaigns often have brand-centric objectives, such as increasing brand awareness or reaching a broad audience within a set timeframe. They're less about immediate conversions and more about high-impact visibility.

Budgeting and Bidding:

• Auction:

  • Budgets in auction buying are flexible. Facebook advertisers can set daily or lifetime budgets and adjust them at any time. Bidding can be automatic (Facebook sets your bid to get the most actions for your budget) or manual (you set your maximum bid).

Auction: Can Set Daily Or Lifetime Budget

• Reservation:

  • Reservation buying involves a fixed cost, agreed upon upfront, providing predictable spending. There's no bidding; instead, you pay for the space and time you've reserved, regardless of how many times your ad is actually shown. Facebook advertisers are also required to use a Lifetime budget.

Reservation: Lock Down Frequency & Budget

Targeting and Placement:

• Auction:

  • Auctions offer sophisticated targeting options, including demographics, interests, behaviors, and custom audiences. You can fine-tune your audience, and placements can be either automatic or hand-picked across Facebook's family of apps and services.

Auction: Audience Options

• Reservation:

  • Reservation campaigns have far less flexibility in targeting, often focusing on broader demographics. The placements are typically predetermined, limiting the ability to optimize ad locations based on performance data.

Creatives and Ad Formats:

• Auction:

  • Auction buying provides a variety of creative formats, including images, videos, carousels, and more. You have the freedom to test different creatives and iterate based on which versions perform best.

• Reservation:

  • With Reservation buying, your creative formats might be limited based on the terms of the reservation. Typically, these campaigns might require higher-quality media and production, considering the scale and cost.

Reservation: Ad Formats

Understanding these nuances is crucial in aligning your campaign setup with your overarching marketing objectives. While Auction provides flexibility and continuous optimization, Reservation ensures predictability and prominent visibility over a specific period. Your choice will depend on the specific needs of your campaign, your budget, and your marketing goals.

Common Misconception With Reservation Buying Type.

A common misconception among advertisers is the notion of 'premium' or 'exclusive' placement that comes with Reservation buying. The belief is that by opting for Reservation, your ads will be "reserved" high-visibility slots, thereby guaranteeing more attention from your target audience.

Facebook operates on a level playing field when it comes to ad placement. Whether you choose Auction or Reservation, the placement of your ads is determined by the same algorithms. These algorithms take into account user behavior, ad relevance, and quality, among other factors. So, despite the fixed cost of Reservation buying, your ad doesn't receive preferential treatment in terms of where it's placed on the platform.

When To Use Auction VS Reservation

Each situation is different, but as rule of thumb. If you are looking for more flexibility in budget and audience creation as well as down funnel conversions then choose the Auction buying type.

On the other hand if you have a set lifetime budget and are looking to run brand awareness Facebook ads. The Reservation buying type might be for you. Just keep in mind that after you upload and reserve your Facebook ads you have locked in your estimate. If you change the Facebook ad... say update your promo or change the Facebook ad this will change your estimated pricing.
