Optmyzr has several tools that help you monitor, project, and actively manage your budgets. The Spend Projection, Optimize Budgets, Budget Pacing, and Budget Automation features each approach budget management differently. This article explains how each of them works and when to use one over another.

The Budget Pacing feature shows what percentage have you spent relative to what you should have spent as a share of the month (linear spending). 

How does it calculate the data?

Budget Pacing shows you the percentage of your target spend you are projected to reach by the end of the chosen budget cycle — based on your current spend rate.

The system uses a dynamic acceptable range that tightens as the cycle progresses. Early in the cycle, a wider range is acceptable because there's more time to course-correct. As you approach the end, the range narrows since there's little room left to adjust.

So if you're at the beginning of the month and pacing shows underspending, it doesn't mean you've already spent too little — it means that if you continue at your current rate, you'll fall short of your target by end of period.

For the suggestions and data shown in the Spend Projection tool, the system uses machine learning to predict the likely spend for each of the remaining days during the selected date range. 

It analyzes actual spend over the past few days to predict the cost the Google Ads account will accrue at the end of the selected time period. Since actual spend levels fluctuate the system predicts a range for the spend.

While we predict the spend in the Spend Projection, we take into consideration the following two factors: 

The Reallocate and Optimize Budgets tool lets you optimize budgets by translating them from monthly to daily budgets. This can be done to achieve a target or allocate more budget to campaigns that are driving more leads/sales. 

This tool analyses the spend on campaigns and shared budgets in your accounts and helps you re-arrange your target budget based on the spending capability of the individual and shared budgets. It also suggests balancing budgets by taking a part of the budget amount that won't end up being spent.

Budget changes made by the Optimize Budgets tool are capped at -20% to +20% per budget per pass, to avoid large corrections in a single run. A 7-day lock is also applied by default after a change is made — budgets will not be adjusted again within that window. This makes the tool suited for less frequent, more deliberate budget changes.

The Budget Automation feature in the Budget Monitor is designed for daily micro-adjustments to keep your campaigns on pace for a spend target. Unlike the Optimize Budgets tool, it runs automatically once per day and can make changes on consecutive days if pacing requires it.

Each day, the system recalculates the ideal daily budget for each campaign based on your chosen spend pattern and remaining target. It then compares this to the current daily budget. If they match, no change is made. If they differ, the updated budget is pushed to the campaign. Changes are kept gradual through built-in guardrails that prevent large single-day swings.

There is no lock period between changes — the automation is intentionally designed to act every day when needed, which is different from how the Reallocate and Optimize Budgets tool works.
