A port's best post is rarely about the port
Two studies of port social media find that audiences engage most with human and community content, that platform choice changes outcomes sharply, and that broadcasting CSR one-way wastes the channel.
Ports spend heavily on infrastructure, dredging, and terminal capacity, and the instinct is to communicate that spending. The published evidence on how port audiences actually behave on social media points the other way. The content that draws the most attention is human and communal, the channel a message runs on changes its reach by orders of magnitude, and the dominant style of corporate posting leaves most of the available value unused.
What audiences engage with
Caliskan and Esmer, in a 2018 study in the Journal of ETA Maritime Science, benchmarked 25 Turkish container ports against Rotterdam, Antwerp, and Los Angeles on Facebook activity recorded in 2016. The findings are exploratory and specific to Turkey, so they should be read as indicative, but the pattern is clear enough to be useful.
The posts that earned the highest engagement contained no port-service, infrastructure, investment, or success-story content. The top performers were special-day greetings, religious festivals, national days, the Day of the Seafarer, and posts on gender equality and social responsibility. The material a port is most tempted to publish, the record of its own capability and expansion, sat well below the material that connected to people and shared occasions.
This sits inside a thin research base. Caliskan and Esmer noted that port marketing accounts for roughly 1.3 percent of port-related academic studies, so practitioners are operating with limited published guidance and a strong default toward self-description. The 2018 data suggests that default is misaligned with how the audience responds. People reward content that treats the port as part of a community and a workforce. They scroll past content that treats it as a balance sheet of assets.
The mechanism is straightforward. Infrastructure announcements speak to a narrow set of commercial counterparties who will learn the relevant facts through direct channels regardless of a Facebook post. Greetings, seafarer recognition, and social-responsibility material speak to a far wider public that has no commercial reason to follow the port and engages only when the content offers something human. The wider public is the audience that grants or withholds local goodwill, and it responds to a different register than the trade press does.
The channel changes the outcome
The same study recorded a single comparison that should reframe how any maritime organisation thinks about distribution. One DP World video drew 573 views on YouTube. The same video drew roughly 25,000 views and 226 shares on Facebook. Identical content, two platforms, a difference of more than an order of magnitude in reach and a step change in sharing behaviour.
The lesson concerns fit between content and platform, and it does not crown one platform as superior. A video built for passive viewing and easy sharing found its audience where sharing is native and the social graph carries it outward. The same asset stranded on a platform where the audience arrives through search and watches in isolation. Producing good content and posting it in the wrong place wastes most of the work.
Platform adoption among large European ports shows the field has not settled on one answer. Vitellaro and colleagues, in a 2022 study in Maritime Business Review, found that across the top 25 EU ports Twitter was the most adopted channel at 88 percent, followed by LinkedIn at 80 percent, with Facebook and Instagram each at 68 percent. Presence on a platform is the first decision. Whether the content suits the platform's audience and sharing dynamics is the decision that determines results, and the DP World figures show how large the gap between those two decisions can be.
Broadcasting wastes the channel
Vitellaro and colleagues also analysed 760 tweets from the Port of Rotterdam published between 2017 and 2019. As a single-port content analysis the results are indicative, but Rotterdam is a sophisticated communicator, so its choices carry weight as a reference case.
Around 36 percent of Rotterdam's tweets addressed corporate social responsibility, and 53 percent of those were themed around green and energy-transition topics. The port had clearly decided that CSR belonged at the centre of its public voice. Two gaps in execution stand out. First, the content skewed heavily toward environmental positioning while community outreach and philanthropy were almost absent, with only 24 tweets across nearly three years despite the port's stated local-community commitments. The themes that the 2018 Turkish data identifies as the highest-engagement material were the themes Rotterdam published least.
Second, and more consequential, the communication ran almost entirely in one direction. Only 17 percent of the tweets received any reply, and the study found effectively no genuine two-way dialogue. The port treated a conversational medium as a broadcast medium. It published statements about its environmental responsibility and largely declined the exchange that would have turned those statements into a relationship. The channel was used as a press-release distributor with the comment field switched off in practice.
What this means for maritime brand strategy
The combined evidence supports an audience-led approach to content over a capability-led one. Ports, terminals, and the operators around them earn public goodwill and a working licence to operate through a human presence that the surrounding community recognises and engages with. The data on engagement points consistently to people-and-community content. Infrastructure and investment material has its place in trade and investor communication, where the audience seeks exactly those facts, but it underperforms as public-facing content and should not crowd out the material that builds standing with the broader public.
Three decisions follow for any maritime organisation building a content presence. Lead with content the intended audience values, which the evidence ties to people, workforce, community, and shared occasions, and reserve self-description for the narrow audiences that require it. Match each asset to the platform where its format and the local sharing behaviour will carry it, since the DP World comparison shows the same content can reach a few hundred or tens of thousands depending only on that choice. Treat conversational platforms as conversations, because the Rotterdam case shows that one-way CSR broadcasting collects little engagement and builds no relationship, leaving most of the channel's value unrealised.
A strong content and brand strategy, built from what audiences actually engage with and delivered on the platforms that fit, outperforms a larger volume of one-way broadcasting about assets and milestones. The maritime sector's published marketing evidence is thin, and the studies above are limited in scope, but the direction they point in is consistent and actionable for any operator that depends on public standing to function.
