Importing Google Ads Campaigns to Microsoft

What the Import Does

The import tool connects to a Google Ads account and copies campaigns, ad groups, keywords, ads, extensions and many settings. It can run once or on a recurring schedule that keeps Microsoft synchronised with Google.

For an advertiser with a mature Google account, this reduces launch from days to under an hour.

What Does Not Transfer Cleanly

Several things need manual attention after import:

• Budgets import at Google levels. Microsoft volume is much lower, so budgets are usually far too high and should be set independently.
• Bids import at Google levels. Microsoft CPCs are generally lower; importing Google bids overpays from day one.
• Some automated bidding strategies have no exact equivalent and fall back to a default.
• Conversion tracking does not transfer. Microsoft needs its own UET tag and its own conversion goals configured before any smart bidding will work.
• Audience lists must be rebuilt using the UET tag; they cannot be copied.

The Recurring Sync Trap

Scheduled recurring imports keep the accounts aligned, which sounds efficient and creates a specific problem: any manual optimisation you make in Microsoft can be overwritten by the next sync.

Decide deliberately. Either treat Microsoft as a mirror and manage everything in Google, or run a one-time import and manage Microsoft independently thereafter. The half-way position — syncing while also optimising manually — produces work that silently disappears.

What to Do Immediately After Import

1. Install the UET tag and verify it fires
2. Create conversion goals and confirm they record
3. Reset all budgets to Microsoft-appropriate levels
4. Reset bids, or switch to manual CPC until there is enough conversion data for automated bidding
5. Review imported ad copy for anything Google-specific that reads oddly elsewhere
6. Pause campaign types that do not exist or do not perform on Microsoft

Skipping the first two steps is the most common cause of a Microsoft account that spends without ever optimising.

The Checklist for the First Week After Import

An import lands a working account and an inherited set of assumptions. The first week is about separating the two.

• Re-check every bid strategy. Automated strategies imported from an account with far more conversion data will behave differently on thinner volume. Manual or enhanced bidding is frequently the right starting point until the account has its own history.
• Halve the budgets, then watch. Search volume is lower, so imported budgets tend to be wrong in the same direction across every campaign.
• Verify conversion tracking end to end with a real test conversion. The import does not bring your tag, and an account optimising against a conversion that never fires will spend the budget and report nothing.
• Review negative keyword lists, which import inconsistently and are the most expensive thing to be missing.
• Check ad extensions individually rather than assuming they came across.
• Turn off the Audience Network initially so you can read search performance on its own, then add it as a separate campaign.

The Sync Trap, and How to Avoid It

Scheduled sync is the feature that causes the most damage, because it is helpful right up until it is not.

The mechanism: a recurring import keeps the Microsoft account aligned with the Google one. The problem is that it can overwrite the platform-specific optimisation you have been doing — the bids you adjusted for lower volume, the negatives you added for different query patterns, the budgets you rebalanced — and it does so silently, on a schedule, without a record anyone reads.

Three workable positions, in order of how much work they are:

Sync off. Manage the account independently and accept the duplication. Correct for any account you are actively optimising.

Sync new items only, where the option exists — new campaigns and ads come across, existing settings are left alone. The usual compromise.

Full sync only where Microsoft is a low-effort mirror nobody optimises, which is a legitimate choice if stated rather than a default nobody decided.

Whichever you choose, write it down in the account notes, because the person who inherits this account will not be able to tell a sync overwrite from a mistake.
