Service · Microsoft Ads
A second search auction is only worth running if it adds profit.
We manage Microsoft Ads in-house for ecommerce brands, judged on the same contribution logic as Google, not on a cheaper-click story.
The question we ask
- Platform ROAS
- Reported
- Contribution
- After costs
- Versus Google
- Same £
- Scope
- Agreed at review
Judged on added contribution, not clicks.
01 / Fit
When Microsoft Ads belongs in the plan
It is an addition to a healthy Google account, not a fix for an unhealthy one.
Where it usually earns a look
Your Google account is already profitable on a contribution basis, your product data is in good order, and there is search demand on Microsoft's network you are not yet reaching.
Where we would hold off
Google measurement is unreliable, the feed has unresolved errors, or the catalogue is too thin for a second auction to carry its own weight. Fixing the core comes first.
How the decision is made
We look at your own account and search data during the commercial review, then agree whether Microsoft Ads is in scope, and what it covers, before anything is launched.
02 / Evaluation
How we judge it
The same commercial read we apply to Google, using the contribution definitions in our measurement framework.
- 01Contribution after COGS, fulfilment, returns and payment fees, not platform-reported ROAS
- 02New versus returning customers, so imported Google tactics are not flattering repeat demand
- 03Overlap with Google Search and Shopping on the same queries and products
- 04Conversion lag and volume before a campaign is judged either way
- 05Whether the incremental spend beats putting the same pounds back into Google
- 06Product-level results against each SKU's commercial job under BOI®
Definitions follow our POAS convention: POAS = contribution before ad spend ÷ ad spend. Contribution after advertising = contribution before advertising − ad spend, so ad cost is subtracted once. Agency fees are defined separately where they are included.
03 / Feed and measurement
What we check before spend goes live
Product feed
Microsoft Shopping runs from a product catalogue in Microsoft Merchant Center, which can be imported from Google Merchant Center. We check which products are approved, how titles, identifiers, prices and availability come through, and whether margin and stock labels survive the import.
Measurement
Conversion tracking is set up and verified on its own terms, with the same contribution values we send to Google where your data allows. Imported Google goals are checked rather than trusted.
Imports from Google
Campaign import can save set-up time. We treat it as a starting draft: budgets, bid strategies, negatives and audiences are reviewed so a Google decision is not copied onto a different auction without thought.
Related: product feed management and Google Shopping. Microsoft's own documentation covers Shopping campaigns and importing from Google Ads.
04 / Relationship to Google
One team, two auctions, one set of numbers
Both accounts are read against the same contribution figures and SKU jobs, so a product we are recovering cash on in Google is not scaled blindly in Microsoft.
Our published case studies are Google Ads evidence. We do not present them as Microsoft Ads results.
How we decide
BOI®
BOI® (Bid On Intent) gives every SKU one commercial job at a time. Bidding follows that job rather than a blended target that quietly averages winners and leakers.
