Z uwagi na rosnące zainteresowanie influencer marketingiem i rolą influencerów w budowaniu relacji pomiędzy markami i ich potencjalnymi odbiorcami umiejętność oceny potencjału cyfrowych i wirtualnych twórców stała się niezwykle pożądana. W monografii omówiono zagadnienia tradycyjnych influencerów i twórców cyfrowych a także influencerów wirtualnych, których aktywność generowana jest komputerowo, między innymi z wykorzystaniem sztucznej inteligencji, uczenia maszynowego i algorytmów. Publikacja podsumowuje aktualny stan wiedzy w obu obszarach a także wskazuje skuteczne praktyki pomocne w przygotowywaniu strategii komunikacji z wykorzystaniem cyfrowych i wirtualnych influencerów. Autorka systematyzuje zagadnienia związane z konsumentem i marką w gospodarce cyfrowej, co stanowi punkt wyjścia do zaprezentowania istoty i charakteru influencer marketingu oraz obszarów niezbędnych do opracowania strategii influencer marketingu. Książka adresowana jest do każdego, kto chce poznać, ugruntować i pogłębić wiedzę i kompetencje związane z influencer marketingiem.
