Manage a shared budget across campaigns

In Google Ads, you can assign a daily budget to each individual campaign, or use shared budgets to allocate budget across multiple campaigns. A shared budget is ideal if you don't have a lot of time to spend setting up and monitoring individual campaign budgets, but would still like to get the most clicks possible for your ads within a set budget. Shared budgets don’t work with campaigns that are part of a campaign group, and campaigns that are part of an experiment.

When a shared budget is in use, Google Ads can automatically adjust how budget is allocated across different campaigns to help you improve your return-on-investment.You can always switch back to using individual campaign budgets for full control over how much you spend per campaign. Go to the Shared library in your account to set up or manage your shared budget.

Example

Say you've set aside $100 per day, split evenly between two campaigns. On a given day, one campaign could get fewer impressions and clicks than usual, resulting in only $40 spent. With a shared budget, Google Ads could take that leftover $10 and reallocate it to the second campaign to maximize your campaign results overall.

Remove a shared budget from a campaign

Because every Google Ads campaign has to have a budget, you can only remove a shared budget if it's not currently being used by any campaigns.

Follow these steps to remove a shared budget from your campaigns and remove it:

  1. Go the "Settings" page for each campaign that uses the shared budget you’d like to remove.
  2. Click Budget.
  3. Under “Enter the average you want to spend each day,” you should see the shared budget applied to this campaign.
  4. Click the “x” on this shared budget to remove it from this campaign.
  5. Click Save.

Repeat the steps above for each campaign that use the same shared budget.

Remove a budget from the Shared library

  1. Click the tools icon , then under “Shared library”, click Shared budgets.
  2. Check the box next to the shared budget you'd like to remove.
  3. Click Edit in the blue bar that appears, and select Remove from the dropdown.

Switching budgets midday

If you switch from an individual campaign to a shared budget or vice versa in the middle of the day, we will start serving from the time you switch, as though the campaigns have spent $0 up until that point.

Example

Let's say you have 4 campaigns, each with an individual budget of $6. By 3:00pm, each of these campaigns has spent their full $6. At 4:00pm, you decide to create a new shared budget of $24 for those four campaigns. We will start your $24 shared budget from $0, as if the $6 campaigns had not already served.
