Retargeting for maritime audiences without being creepy

Retargeting works differently in maritime than in most B2B sectors. The buying cycles are long, the buying committees are stable and the buyer’s tolerance for ads they did not consent to follow them around is roughly zero (because the buyer is a senior corporate professional with strong privacy preferences, not a consumer browsing for trainers).

Designed badly, maritime retargeting becomes the worst kind of brand experience: a fleet director sees the same banner ad on every news site they visit for six months and the brand association becomes irritation rather than familiarity. Designed well, retargeting is the most cost-efficient way to keep a long-cycle prospect engaged without burning brand equity.

Here is how we build it.

Segment by behaviour, not by visit

The lazy retargeting setup is “anyone who visited the site in the last 30 days, see the same generic ad”. The thoughtful setup segments by what the visitor actually did:

• High-intent visitors: visited a specific service page, downloaded a brochure, viewed a case study, started a contact form. These are warm and worth pursuing aggressively.
• Mid-intent visitors: visited a blog article, the about page, the team page. These are exploring and need light-touch contact.
• Low-intent visitors: visited only the homepage and bounced. Usually noise, often candidates for exclusion rather than retargeting.

Build separate retargeting campaigns against each segment with different creative, different frequency caps and different windows.

Frequency caps that respect the audience

Standard B2B platforms recommend frequency caps of 3 to 7 impressions per week per user. For maritime, that is too high.

We typically run:

• High-intent: 3 impressions per week, capped at 25 impressions per 90 days
• Mid-intent: 2 impressions per week, capped at 15 impressions per 90 days
• Low-intent: 1 impression per week, capped at 8 impressions per 90 days, often excluded entirely

Frequency caps need to be set at the campaign level on every platform. LinkedIn’s defaults will cheerfully serve 30 impressions per week to the same user.

Window length matched to cycle

A 30-day retargeting window catches almost none of a maritime sales cycle. A 90-day window catches most of the consideration phase. A 180-to-540-day window catches the procurement and shortlisting phases.

The trade-off is that long windows accumulate audience members who have moved on or never had real intent. Combine long windows with frequency caps and behavioural exclusions (for example, exclude anyone who has visited the careers page in the last 30 days) to keep the audience clean.

Creative that earns the impression

Retargeting creative cannot be the same generic awareness creative used in prospecting. The viewer has already seen your brand. The retargeting impression should add information.

Useful retargeting creative formats for maritime:

• Case-study-led: a specific outcome (“scrubber retrofit completed in 28 days for product tanker”) with a link to the full case study
• Authority-led: a recently published technical piece, a sector report, a webinar replay
• Specific offer: a benchmarking exercise, a free fleet review, a class-society compliance check
• Personnel-led: a senior subject-matter expert speaking to camera about a specific topic

Avoid product-feature retargeting in B2B maritime; the buyer has not made a product-level decision yet and feature-listing creative bores them.

Channels that matter for retargeting

LinkedIn is the most expensive retargeting channel and the highest signal. Run it for high-intent segments and decision-maker-level visitors only.

Meta and Google Display are the cost-efficient frequency channels. Use them for mid-intent segments and for keeping the brand visible during long quiet phases of the cycle.

YouTube TrueView is the most under-used retargeting channel in maritime. A 30-second video targeted at past visitors of a specific service page, with a clear call to action, can deliver completed views at £0.05 to £0.15 each.

Credible presence, not pursuit

Retargeting in maritime is not about reminding someone of an abandoned cart. It is about staying credibly present across a year-long evaluation, without becoming the company that haunts the buyer’s screen. Discipline on segmentation, frequency and creative is how that balance gets struck.
