Performance advertisers on the open web live and die by using their budget efficiently; as a result, real-time pacing adjustments are critical to a campaign’s bottom line. By actively monitoring campaign pacing indicators, you can quickly identify whether an algorithm is starved for impressions, or if you’re burning through your monthly limit.
Learn how to read the Realize color-coded pacing indicators, and use them to make strategic moves, such as tweaking bids or updating delivery settings, so your budget drives maximum conversions without any disruption.
Diagnosing Pacing Health: Identifying Overpacing vs. Underpacing
The pacing health score lives in your campaign-level reporting, in the Default view, as a dedicated Pacing column. This score is the core tool Realize provides for optimizing campaign budget utilization in real time. It’s only visible for campaigns with a Running status, and it tracks Monthly or Lifetime budgets. Daily budgets show a dash because pacing health is designed to track depletion over a longer trajectory (rather than a single day).
The color-coded indicator breakdown
| Pacing Range | Status | Indicator |
| Less than 50% | Highly Under Pacing | Red |
| 50% to 94.9% | Under-Pacing | Yellow |
| 95% to 109.9% | On Track | Green |
| 110% to 149.9% | Over Pacing | Yellow |
| 150% or more | Highly Over-Pacing | Red |
You’ll notice that the gap between 95% and 110% is considered the healthy middle ground. In this zone, the algorithm spend aligns with the actual spending required to fully use the budget by the end of the period.
Before you touch a thing, confirm where the campaign is in its lifecycle. If it’s brand new, swings in either direction are expected, and they’re not a problem to fix. Remus de Jesus, senior advertising account manager (growth) for Realize, explains that pacing fluctuations are normal early on, and recommends allowing the data to settle, rather than chasing early noise. Because reactive changes during the learning period tend to do more harm than the fluctuation itself, give it time before you optimize based on what you’ve observed after just a few days.
Real-Time Strategy Adjustments for Underpacing Campaigns
When a campaign’s pacing drops and enters yellow or red territory, the algorithm is likely starved for inventory, or it’s hitting restrictions that prevent it from spending. You can adjust campaign strategy in real time when that happens.
Audit for suppression first
A premium publisher’s AI moderation tools can quietly suppress headlines, which can tank delivery without anything else changing on your end. De Jesus cites an example of MSN’s AI systems suppressing Kindle-related headlines, which caused a noticeable dip in spend. Pulling those trigger words can restore pacing almost instantly, so check here first before touching your targeting or bids.
Loosen targeting
Age demographics, third-party marketplace clients, and other narrow segments can shrink your available inventory pool to the point where the pool is unable to find conversions. Expanding toward first-party data gives it more to work with.
Modify your bid strategy
A bid that’s too conservative in a competitive auction environment can cap your delivery at zero percent pacing. The algorithm loses every auction it enters because there’s always someone else willing to pay more for the same impression.
The conundrum? Creating a campaign set to win cheaply may result in winning nothing. If you’re underpacing and your bid is lower, you can try a quick fix by transitioning to a Target CPA setup or SmartBid. This allows the system to flex its bid up in auctions where conversion likely justifies the extra spend; there’s no need to maintain a flat ceiling across all impressions regardless of quality.
Real-Time Strategy Adjustments for Overpacing Campaigns
Overpacing (anything above 110%) can trigger a reflexive instinct to pull back. Resist the urge before you evaluate the quality of what’s coming through.
A campaign that’s running hot usually means the algorithm has found a high-performing inventory pocket. If the surge pairs with a strong CPA — or a wave of high-value conversions — the smarter move is to lean in. (Don’t restrict it!) Target CPA (tCPA) automated bidding is built to pursue this type of opportunity; an overpacing campaign on a tCPA strategy is frequently doing what it’s designed to do.
Brant McLean, Realize’s head of growth for the US, frames overpacing as a signal, explaining that Realize updates are designed to help partners identify better swim lanes and expand confidently. He views overpacing not as a budget leak, but as a signal that the system has identified a pocket of inventory that’s converting well.
De Jesus notes that when performance is strong, the move is to aim higher. An overpacing campaign still hitting its CPA signals the potential for horizontal scale; it’s not a reason to throttle.
Lauren Wint, advertising account manager at Realize, suggests transitioning from broad targeting to Predictive Audiences once you’ve got strong performance signals, explaining that this change allows the campaign to keep handling high volume while simultaneously lowering CPA. The result is that you don’t have to choose between scale and efficiency.
A benefit of all this is that increasing your budget to match the algorithm’s winning trajectory (assuming your ROAS justifies the spend) is more effective than throttling delivery, which risks losing premium placements you’ve already earned.
One Thing to Avoid: Resetting Learning with Reflexive Changes
It’s important to avoid making too many structural changes at once in reaction to a pacing color you don’t like.
Major edits to targeting, creative, or landing pages force the algorithm to reevaluate its assumptions from scratch. So, a campaign that’s underpacing because it’s in its mid-learning period can underpace for longer if you respond by overhauling three things simultaneously. Rather, you should make one targeted adjustment and give it room to respond.
A better approach to a pacing color you don’t like:
- Make a single change.
- Wait a few days for the system to absorb the change.
- Assess whether pacing has adjusted before making an additional change.
A pattern of frequent, stacked edits is one common reason why a campaign never quite escapes the volatility of its early days. The underlying targeting or bid strategy wasn’t wrong — instead, the algorithm never got a clean enough window to prove it.
Real-Time Pacing Levers: The 10x CPA Rule and “Pace Ahead”
Before you ever get to real-time bid adjustments, your structural bid setup is doing much of the work (or interfering with it).
A good rule of thumb is to set your daily budget to at least 10x your target CPA, which gives the algorithm enough at-bats in the auction to find cheap wins without capping out early in the day. Practically, if your target CPA is $45, you need a $450 daily budget so the system has enough room to test and stabilize.
Because an algorithm typically needs about ten daily conversions to optimize, you need built-in space for your budget. A restrictive budget relative to your target CPA impedes the system’s ability to gather data, which can manifest as chronic underpacing, regardless of your bid or targeting strategy.
Still see persistent underpacing even though you’ve structured a campaign correctly? Check your Pace Ahead lever. This setting accelerates spend by targeting 120% of your daily allowance, effectively forcing the algorithm to search more aggressively for inventory in a crowded marketplace.
The connection to learning speed is direct: The system optimizes off conversion data (which only accumulates as spend occurs), so accelerating spend hastens the rate at which the algorithm accumulates the signal it needs to stabilize. Wint points to this strategy as a strong move for newer campaigns, helping them get through the learning phase a lot quicker.
In practice, a campaign that otherwise might spend a week and a half gathering enough data to optimize with confidence could reach that same threshold in a few days, because it’s got more room to spend toward it.
Key Takeaways
Open web advertising rewards real-time responsiveness, and the pacing health score facilitates that responsiveness without any guesswork. The Realize color-coded indicators can tell you at a glance whether you’re underpacing, overpacing, or pacing just right.
Each status points to a different, specific lever:
- Loosen targeting and check for suppression when you’re starved for inventory.
- Lean into momentum and consider a budget increase when you’re overpacing due to strong performance.
- Structure your budget around the 10x CPA rule so the algorithm never runs out of room for target CPA optimization.
Mastering those levers — bid, audience, and delivery settings — keeps a campaign on track for its CPA targets and helps prevent it from drifting in either direction.
Frequently Asked Questions (FAQs)
Should I adjust my campaign strategy if it’s overpacing during the first few days?
Resist the urge! Early-stage pacing swings in either direction indicate that the system is testing inventory and calculating the source of conversions; it’s not a signal that something’s broken. Pull a lever too soon, and you may interrupt that process. Wait for the learning period to end, and let the pacing score settle before you start making changes based on what you see.
How does my daily budget limit impact algorithmic pacing?
More directly than you might expect. The algorithm needs a steady flow of conversions to learn from. A too-tight daily budget relative to your target CPA chokes the flow before the algorithm can gather enough signal. The 10x rule (a daily budget of at least 10x your target CPA) helps avoid that bottleneck. If you set the budget too close to your CPA goal, you may see chronic underpacing, even with a well-constructed targeting or bid strategy.
Can I track pacing health on campaigns with a daily budget type?
No, you can’t track pacing health on campaigns with a daily budget type. Pacing health measures depletion across a month (or the campaign’s lifetime), whereas daily budget campaigns show a dash (-) in the pacing column. If you’re running daily budgets and trying to gauge delivery health, look at the spend trends directly; don’t rely on this indicator.
