Most affiliates who try Microsoft Ads for affiliates campaigns quit in the first two weeks, and it is almost never because the traffic was bad. It is because they ran a Google playbook on a platform with different compliance rules, different audience behaviour, and a different auction – then read the first seven days of data as a verdict.
The arbitrage is real, though, and the numbers are not close. WordStream’s 2026 benchmarks put the average Google Search CPC at $5.42 with a cost per lead of $66.69, across 13,474 US campaigns. On thin affiliate margins, $5.42 a click is not a business. Microsoft’s search inventory routinely clears for meaningfully less, for the simple reason that roughly 36% of US advertisers are on Microsoft against about 80% on Google. Fewer bidders, cheaper clicks, same commercial intent.
There is a trap here that catches almost everyone, and it has a name: the Dunning-Kruger effect. Affiliates who are genuinely good at Google Ads arrive at Microsoft confident that the skills transfer one-to-one. Most of them do. The handful that do not – editorial policy, tracking parameters, audience skew – are exactly the ones that get an account suspended in week one.
Five tips. Ordered by what will make or break your first month, not by what is most interesting.
Table of Contents
1. Read the Editorial Policy Before You Build Anything
This is the tip that saves accounts, so it goes first.
Microsoft’s editorial review is stricter than Google’s in several specific places that affect affiliates directly. Thin affiliate sites get rejected. Pages that exist only to redirect to a merchant, with no original content, no unique value, and no clear identity, will not survive review. Microsoft wants to see a destination that is a real property.
What “real property” means in practice:
- Original content on the page beyond the offer itself
- Visible contact information and a privacy policy
- Clear disclosure that you earn commission
- No cloaking, no redirect chains, no landing page swaps after approval
The categories that need extra care: health and supplements, finance and credit, gambling, dating, and anything making earnings claims. These are not blocked, but they are reviewed harder and the claims you can make are narrower.
The practical move: get one campaign approved on your cleanest, safest offer first. Build account history. Then expand into your more aggressive verticals from a position of standing rather than starting there. An account with three months of clean history gets treated very differently from one that appeared yesterday.

2. Do Not Import Your Google Campaigns Unedited
Microsoft’s import tool is excellent and it is also how most affiliates poison their first month.
Import, absolutely. Rebuilding from scratch is a waste of a day. But affiliate campaigns on Microsoft Ads need four edits immediately after import, before you enable anything:
- Strip Google-specific tracking parameters. ValueTrack parameters do not map one-to-one. Broken tracking on day one means you spend a week optimising against nothing. This is the most common single failure.
- Rewrite the ad copy. Microsoft’s audience is older and more likely searching from a work desktop. Copy that lands with a 28-year-old on mobile often reads as noise to a 48-year-old on a corporate machine. Test more formal, more specific, more proof-led angles.
- Review the search partner settings. Imported campaigns inherit settings that expose you to partner inventory you may not want at the start. Tighten it, then loosen deliberately once you have data.
- Cut your keyword list by half. Microsoft has lower volume than Google. A 2,000-keyword account spreads spend so thin that nothing accumulates enough data to optimise. Start with your proven winners only.
Adcore’s walkthrough on how to get started with Microsoft Ads covers the import mechanics in detail.
3. Match Your Offers to Microsoft’s Audience
Affiliate marketing on Bing fails most often when a perfectly good offer meets the wrong audience.
Microsoft’s search audience skews older, higher household income, and more likely to hold a management-level role – largely because Bing is the default in Windows, Edge, and Office, so a large share of searches happen on a work machine during business hours.
Offers that tend to over-index on Microsoft:
- B2B software and SaaS trials
- Financial services, insurance, mortgage and credit comparison
- Professional services and certifications
- Home improvement, home services, and higher-ticket retail
- Health products aimed at 40+ audiences
- Travel with a considered purchase cycle
Offers that tend to under-index:
- Gaming and app installs
- Youth fashion and trend-driven DTC
- Anything requiring a mobile-first, impulse purchase
This is not a small optimisation.
Moving the same budget from a poorly-matched offer to a well-matched one frequently changes ROI more than every bid adjustment you will make all quarter. Pick the offer for the platform rather than forcing the platform to serve the offer.
4. Get Tracking Right on Day One
Affiliates lose more money to broken measurement than to bad media buying, and it is almost always fixable in an hour.
Install the UET tag properly. Universal Event Tracking is Microsoft’s equivalent of the Google tag. Install it, verify it fires, and define at least one real conversion goal before you spend anything.
Where affiliates specifically get stuck: when the conversion happens on the merchant’s site, you cannot fire a UET tag on it. Your options, in order of preference:
- Postback / server-to-server from your affiliate network into Microsoft, if the network supports it. This is the correct answer.
- Offline conversion imports using the Microsoft Click ID (MSCLKID), matched against your network’s reporting.
- A proxy conversion on your own page – an outbound click to the merchant – as a last resort. It is not revenue, but it is a consistent signal the algorithm can optimise toward.
Pass MSCLKID through to your network’s sub-ID field. Without it you can never attribute a commission back to a keyword, and you will be optimising blind for as long as the campaign runs.
Verify before you scale, not after. Run $20 through the funnel and confirm a test conversion lands in Microsoft’s interface. That single check has saved more affiliate budgets than any bidding strategy.
5. Judge Affiliate ROI on the Right Window
The last tip is the least glamorous and it is why most affiliates quit too early.
Set a 30-day conversion window, not 7. Microsoft’s audience skews toward considered purchases. A seven-day window will systematically hide conversions that happened and hand you a false negative.
Give the campaign 30 days before a verdict. Lower search volume means signals accumulate more slowly. The first week is calibration, not performance.
Watch commission-adjusted ROI, not CPA. A $40 CPA on a $120 commission beats a $25 CPA on a $50 commission every time. Affiliate ROI is a margin calculation, and CPA alone will lead you to optimise toward your worst offers.
Reconcile against your network dashboard weekly. Microsoft’s reported conversions and your network’s confirmed commissions will not match. Your network is the source of truth. Reconcile, then feed the true numbers back as offline conversions so the algorithm learns from reality.
One structural shortcut worth knowing: getting favourable terms, ad credits, and platform-level support as an independent affiliate is difficult. Adcore’s Channel Partner Program exists for exactly this – it is free to join with no spend minimum, it covers Microsoft account setup and billing, it provides access to ad credits that directly improve your margin, and your offers, relationships, and billing stay entirely yours.
CONCLUSION
Microsoft Ads for affiliates works for a boring structural reason: the same commercial intent is available in a much emptier auction, and thin margins survive cheap clicks in a way they cannot survive $5.42 ones. The five things that decide your first month are compliance, a properly edited import, offer-to-audience fit, closed-loop tracking, and a 30-day window.
