Highest volume
- Also called Highest volume bid strategy
- Updated November 4, 2026
Highest volume is a Meta bid strategy that tells the auction to get as many results as your budget allows. You set no cost target and no cap. Meta bids for you, tries to spend the full budget, and your cost per result rises and falls with competition. If you leave the control amount empty when you set up an ad set, this is the strategy Meta uses.
What does Meta say highest volume does?
From About highest volume: "When you use the highest volume bid strategy, we'll aim to get the most results possible from your budget." Meta's example is an event planner filling a music festival, "where cost per attendance doesn't matter."
On About bid strategies it is one of two spend-based options, a group Meta describes as "getting the most results or value possible by meeting your full spend need." There, the wording is "Maximize delivery and conversions you can get from your budget." It is also the default. Meta's About cost and bid controls page says "If you don't enter a control amount, we'll use the highest volume bid strategy".
Meta says it fits if you "Care about spending your full budget", "Don't have a specific cost per action (CPA) goal", and "Aren't aiming for specific goals to measure or define success (for example, a 110% return on ad spend)."
Why does my cost per result change on highest volume?
Because nothing holds it in place. Meta's warning:
The highest volume bid strategy doesn't optimize for CPA. We'll aim to get you the highest volume of results available, but your CPA may fluctuate. For example, if auction competition decreases, costs may go down. If auction competition increases, costs may go up.
A busy week can raise your cost per result with no change to your ads. Before blaming the creative, check whether the cost moved across every ad in the account or just one.
How is it different from the other bid strategies?
| Strategy | Type | What you enter | What gives way when the auction gets expensive |
|---|---|---|---|
| Highest volume | Spend-based | Nothing | Cost per result |
| Highest value | Spend-based | Nothing | Return on each sale |
| Cost per result goal | Goal-based | An average cost | Spend |
| ROAS goal | Goal-based | An average return | Spend |
| Bid cap | Manual | A maximum bid | Spend |
Meta's bid strategies FAQ says spend-based bidding "prioritizes spending your full budget without guaranteeing specific cost efficiency—even when the market becomes more competitive." For a new account it also says: "If you don't have historical data, run a Highest volume or Highest value campaign first to establish a baseline". The full comparison is under bid strategy.
Where does Meta require highest volume?
Two features ask for it.
Ads Manager's creative test is the strict one: "Creative testing is supported in campaigns using the Highest volume bid strategy only." Custom attribution is looser. Meta says it suits advertisers who "Currently use/or willing to use highest value or highest volume" bidding.
What it means for your ads
Run it first to find out what your results cost. Meta's FAQ suggests that order, because a baseline from a highest volume campaign gives you the number a cost goal would need.
Switching isn't free, though. "Changing bid strategy" is on Meta's list of significant edits, so moving a running campaign to highest volume for a creative test sends its ad sets back into the learning phase. Plan the test for a campaign you can leave alone for a while, or budget for the unsteady days.
If a campaign has a cost you must not exceed, look at a cost per result goal or a bid cap instead, knowing that either can leave budget unspent.
