Microsoft Advertising: the underrated channel

Less reach, considerably less competition and an audience sitting at a work computer. Why the second look pays off, especially in B2B.

Microsoft Advertising: the underrated channel

Key points

  • Click prices frequently sit 20 to 40 per cent below the market leader.
  • The channel over-indexes on users at corporate machines.
  • Importing existing campaigns takes minutes; the follow-up work still takes hours.

Microsoft Advertising serves Bing, Yahoo, DuckDuckGo and search inside Windows. Market share in Western Europe sits between 4 and 10 per cent depending on the measurement. That number explains why the channel gets overlooked, and it conceals why it can still pay.

Who searches there

The user base differs structurally, because Bing is the default in Windows and Microsoft products. That produces an above-average share of searches from corporate machines, from older audiences, and from people who never changed the default.

For suppliers of office software, industrial supplies, training or staffing that is good news. For a fashion label with a young audience it is not.

What the channel costs

MetricRatio to the market leader
Cost per click60 to 80 per cent
Search volume5 to 12 per cent
Conversion ratecomparable to slightly better
Maintenance effortabout 20 per cent extra

Cheaper clicks combined with comparable conversion rates give many B2B accounts a cost per enquiry 25 to 35 per cent below the main channel. Absolute volume stays small; the return is good.

The import and its traps

Importing existing campaigns takes a few minutes. That is precisely the danger: an imported account is a copy, not an adaptation.

Three things need checking afterwards. Budgets carry over even though search volume is a tenth, so an imported £3,000 budget will never be spent and distorts planning. Tracking parameters from the main channel do not work here and must be replaced, or measurement is blind. Audiences and exclusions do not all transfer, and customer lists in particular must be uploaded again.

An imported account nobody maintains delivers worse numbers after three months than a hand-built one on half the budget.

What is possible here and not elsewhere

The channel offers a few controls that can justify the effort. Targeting by industry, company size and job function drawn from the same group's career network is a real advantage in B2B. Device targeting is more granular. And delivery in the syndicated partner network can be switched off entirely, which cuts waste sharply.

That last point matters. The partner network delivers cheap clicks of doubtful quality. Switch it off at the start and enable it only if you need volume and can measure its quality separately.

A sober recommendation

Start with the channel when your main account is stable and you reach an impression share above 70 per cent there. Allocate 10 to 15 per cent of the search budget. Expect three months before the numbers are meaningful, because lower volume slows data collection.

If your business is B2B, reverse the order and test earlier.

Frequently asked questions

Is it worth it for local businesses?

Usually only once the main account is maxed out. At small search volumes too little remains to justify the maintenance.

Can campaigns simply be imported?

Yes, the import is reliable. Taken over unchecked it means the platform's own options go unused.
