Microsoft Ads for maritime: why it often outperforms Google

Most maritime businesses spend nothing on Microsoft Ads. The ones who do, almost universally, find that it punches above its weight against the Google numbers. The reason is a quirk of the maritime buying audience.

Maritime decision-makers skew older than the general B2B audience. They sit in larger corporates with locked-down IT estates. The default browser on those machines is often Edge, the default search engine is often Bing and (more significantly) the workplace machines are frequently joined to Microsoft 365 environments where Bing is the default search experience inside Windows search and Office.

On any given maritime query, Microsoft’s share of impressions is small. But the share of impressions among actual fleet directors and technical superintendents is meaningfully higher than its overall share. That is the arbitrage.

What we typically see in the numbers

Across maritime accounts running parallel Google and Microsoft campaigns on identical keyword sets, the pattern is consistent:

• CPCs are 30% to 60% lower on Microsoft for the same keyword
• Click-through rates are similar or slightly higher
• Conversion rates are similar to slightly higher
• Cost per qualified lead is materially lower (often half)

The volume cap is the constraint. You cannot scale Microsoft to absorb a £20,000 monthly maritime budget. But the first £3,000 to £6,000 of monthly maritime search budget is often more efficient on Microsoft than on Google.

Where Microsoft genuinely wins

LinkedIn data integration. Microsoft owns LinkedIn, and Microsoft Ads lets you target search queries by company, industry and job function pulled from LinkedIn profiles. That is a capability Google does not have. For maritime services businesses with named target accounts, the LinkedIn-layered targeting on Microsoft search is genuinely useful.

A tanker-services campaign can be set to bid more aggressively on search queries where the user’s LinkedIn profile shows employment at a tanker-owning company at director-or-above seniority. The audience size on any given query is small, but the conversion intent is sharp.

Where Microsoft does not work

Display and audience network performance is materially weaker than Google’s display equivalents. Inventory quality is mixed and most maritime accounts find that the audience-network setting (on by default in Microsoft search campaigns) drags overall performance down.

Switch the audience network off until you have at least 90 days of clean search-only data. Then test it as a separate campaign with its own budget cap, not bolted onto the search campaigns.

How to build a Microsoft Ads account for maritime

Three principles:

• Mirror, do not copy. Import the structure of your Google account, then prune it. Many Google search campaigns rely on volume that does not exist on Microsoft. Combine the lower-volume campaigns to keep ad-group statistical power.
• Use the LinkedIn layer. Add bid modifiers based on LinkedIn industry and job function on every campaign. This is the feature that makes Microsoft Ads worth running in the first place.
• Watch the quality score equivalent. Microsoft’s “Quality Score” is calculated differently and is more forgiving than Google’s. Do not assume your Google ad copy will land at the same quality on Microsoft. Some keywords need re-tuned ads.

A word on Yahoo

Microsoft Ads also serves Yahoo and AOL search inventory. The audience composition there is genuinely older, and for some maritime segments (US-based offshore operators, older European tanker owners) it can deliver a meaningful share of impressions. Do not turn it off without testing.

A defensible default

Microsoft Ads will not replace Google in a maritime paid-media programme. It will, almost always, sit alongside Google as a secondary channel that delivers the cheapest qualified leads in the account. Twenty per cent of maritime search budget on Microsoft is a defensible starting point.
