Despite all these years and fluctuations in popularity of online forums and social networking sites, the Polish blogosphere has managed to maintain its strong position among Internet users. According to the Public Opinion Research Centre report from April 2017, as many as 31% of Internet users in Poland read blogs. This number has not changed significantly for years, and hovers at some 30%. The blog themes which narrow down to specialist fields allow to reach precisely defined groups of recipients. Thanks to the platform's progressing professionalization, marketing activities carried out in cooperation with bloggers cover now a vast range of services.
