Microsoft Advertising Imports: Audit the Schedule Before You Sync
A Microsoft Advertising import is not always a one-time migration. If an automatic schedule remains active, later runs can continue fetching Google Ads changes and updating Microsoft Advertising campaigns according to the options you selected.
That can be useful when Google Ads is the source of truth. It can also reverse a deliberate Microsoft-side decision. Microsoft documents that scheduled imports may update existing campaign statuses, bids, bid strategies, and budgets when those settings are enabled. Treat the schedule as an active synchronization process, not as a harmless backup.

Before you enable or change a schedule
Open Import Center or Import schedule & history and look for every active schedule. Check both the account and manager-account levels. A schedule created by another agency may also be present, and Microsoft says you may be unable to edit or delete one created by another agency linked to the account.
- Confirm the source and destination. Verify the exact Google Ads account being imported into the exact Microsoft Advertising account. This is especially important for agencies managing multiple clients or brands.
- Assign ownership by setting. Decide whether Google Ads or Microsoft Advertising owns campaign status, budgets, bids, bid strategies, targeting, URLs, audiences, and tracking-related settings. Do not enable recurring updates until that ownership is documented.
- Review existing-item updates. If updates to existing items are enabled, a campaign paused in Microsoft Advertising may be re-enabled when its Google Ads counterpart remains active. Bid, bid-strategy, and budget updates are controlled by their own import settings.
- Review deletion behavior. The import can delete items removed from Google Ads when that option is selected. This may fit a direct mirror, but it can be risky when Microsoft campaigns include independent landing pages, local targeting, or separately managed ad groups.
- Check currency and minimums. Microsoft Advertising has different bid and budget requirements. Microsoft says it may raise values that are below its minimums unless you opt out, and currency mismatches may require conversion or manual adjustment.
What to do next
Run a controlled import before committing to a recurring schedule. Record the source account, destination account, schedule, selected entities, deletion option, bid and budget adjustments, status settings, UET associations, and conversion-goal options.
After the import, compare the source and destination at the campaign level:
- Campaign status and serving state
- Daily budgets, bids, bid strategies, and currency
- Locations, schedules, devices, networks, and exclusions
- Final URLs, tracking templates, and conversion settings
- Audience associations and membership durations
- Performance Max structure, asset groups, assets, feeds, and final URL expansion
Performance Max should be treated as a mapped implementation, not a guaranteed structural clone. Microsoft says new Google Performance Max campaigns generally import as Microsoft Performance Max campaigns, but some may import as Search campaigns. Video assets are not currently imported, and stock-image limitations may prevent some asset groups from importing.
Conversion goals deserve a separate check. Microsoft states that if a Performance Max campaign does not have a Microsoft Advertising conversion goal during import, its bid strategy may be converted to Maximize Clicks. After a conversion goal is created and sufficient conversion data is tracked, the campaign may switch to a conversion-based strategy. Confirm that the intended goal exists, is eligible for optimization, and receives data through the required Microsoft UET implementation.
Do not assume audience parity. Microsoft’s current import table excludes customer lists, Google Analytics remarketing lists, YouTube visitor lists, affinity audiences, and detailed demographics. Some website-visitor and in-market audiences are supported, but membership durations above 180 days may be reduced to 180 days.
Finally, download the import error file and resolve parent-level campaign errors first. Microsoft notes that child updates and deletions may be skipped when a parent entity fails. Also compare the import summary with Change history: the import update count can include existing items that were fetched but not materially changed.
If a Microsoft-side governance or optimization decision must persist, pause or revise the schedule before making the change. The practical goal is not to avoid imports; it is to ensure the schedule matches the platform that owns ongoing campaign decisions.
