strategic position for the Polish economy, being a place
of employment for around 350 employees [24].
Next on the list is the Lithuanian seaport located in
Klaipeda, which covers a total area of 1442.8 ha
(including a land area of 557.9 ha) and is the closest to
the ports of Western and Northern Europe and the
ports of southern Scandinavia. The Port of Klaipeda is
a deep-water, multi-purpose and multi-functional port
handling petroleum products, containers, general
cargo, bulk and liquid cargoes, ro-ro cargoes, bulky
cargoes and many other cargoes (such as fertilisers,
mineral and chemical materials, agricultural products,
metal products, liquid and frozen food products,
construction materials, wood, peat). The Lithuanian
port also serves cruise ship passengers [11]. The port is
the largest port in Lithuania and contributes to the
country's economy and is important for its
development, as evidenced by the fact that it generates
6.18 per cent of Lithuania's total GDP and provides
more than 58,000 jobs [23].
Another of the largest ports of the Baltic Sea basin is
located in the German city of Rostock. Its total area is
approx. 750 hectares. The Port of Rostock handles both
general cargo such as steel and timber products, heavy
and oversize cargo and so-called project cargo, dry
bulk cargo such as coal, building materials, fertilisers
and cereals, and liquid bulk cargo: fuels, crude oil,
liquid fertilisers. In addition, the Port of Rostock
handles passenger ferries and ro-ro vessels and is a
thriving cruise centre. The aforementioned seaport is
one of the most important maritime transport hubs in
eastern Germany with a large impact on the economy
due to the fact that there are about 150 enterprises
operating in the port and its surroundings, which are
directly or indirectly related to the maritime economy,
being the place of employment of about 16,000 people
[13, 27].
Another of the largest Baltic seaports is the port of
Gdynia, located on the Bay of Gdańsk. It is one of the
leading ports in the southern Baltic Sea covering a total
area of 2996.3 ha (including a land area of 903.1 ha). The
Port of Gdynia is a multi-purpose port specialising in
general cargo, including mainly unitised, containerised
and ro-ro cargo. An important segment of activity is
also the handling of bulk cargo based on specialized
terminals, as well as ferry and passenger service. The
Port of Gdynia is one of the largest employers in
Pomerania with an international profile [21].
The last of the ten largest ports in the Baltic Sea is
the port located in the Latvian capital, Riga. It is the
main port on the eastern coast of the Baltic Sea, which
is located at the mouth of the Daugava River in the Gulf
of Riga and currently covers an area of 6348 hectares
(including 1962 hectares – land area). The port handles
petroleum products, coal, container and general cargo,
dry cargo, liquid cargo, chemicals, agricultural
products, metal, roll-on/roll-off cargo, construction
materials, timber, peat [5, 11]. The port of Riga is the
largest port in Latvia, delivering more than 50% of the
volume of cargo handled at Latvian ports annually. It
covers more than 200 companies, including, among
others, transshipment and storage terminals,
manufacturing, shipbuilding and repair companies
and ship agencies, and employs more than 4,000
people [5].
To sum up, ports are integral elements of the
transport and logistics system of each coastal country,
which play an important role in its economy, actively
influencing not only the efficiency and effectiveness of
the TSL sector [7], but also influencing to a large extent
many groups of potential stakeholders (by generating,
among others, many thousands of jobs or impacting
the local community). And building good relationships
with stakeholders can be achieved, among other
things, by companies maintaining social media
activity, which companies are increasingly using
effectively in their marketing strategies [1].
2.1 Research methodology
In order to achieve the assumed goal of the work, the
desk research method and the observation method
were used in the research. First of all, in order to verify
the current state of knowledge, a desk study was
conducted, including content analysis and available
statistical data, and a cross-sectional analysis and
comparison of historical data [2] was carried out,
focusing particularly on the topic of the largest Baltic
seaports.
In the next step, an observational survey was
conducted to identify marketing activities carried out
on popular social media sites by the largest ports in the
Baltic Sea region. This method is considered to be the
most elementary method of empirical cognition,
consisting in the purposeful and systematic perception
of the object, process or phenomenon under study [17].
A type of covert observation was used in this study, as
the social networks are publicly accessible [6] and the
administrators of the selected profiles were not
informed that their activities were being studied.
The observation process carried out consisted of
several stages. Firstly, a survey site was selected where
the objectives could be met - these were popular social
media sites/websites such as: Facebook, Instagram, X
and LinkedIn. All of the aforementioned sites (except
LinkedIn) are ranked as the most used social media
platforms in the world. According to Digital 2024:
Global Overview Report, Facebook is used by 3049
million users, Instagram by 2000 million and X by 619
million (with the caveat that users may not represent
unique individuals) [4]. LinkedIn, despite not being
included in the aforementioned ranking, was included
in the analyses due to the fact that it is a professional
social platform designed for the business community.
The study was conducted in the period December 2024-
January 2025. The next stage of observation was to
perceive, collect and record the data obtained, in order
to then move on to the final stage of drawing
conclusions from the observations and interpreting the
data obtained as part of the analysis.
Within the framework of this study, observation
was carried out via the web, which is also referred to
as web-based ethnographic research [10] or
netnography, or sometimes virtual ethnography [9].
The advantage of ethnography is the ability to conduct
observations in completely natural circumstances,
where the researcher is invisible to the observed,
because he uses qualitative data available to the public
(e.g. on Internet forums or social networks). The object
of observation was the profiles of the largest seaports
in the Baltic Sea region in terms of volume of cargo
