The State of Retailing Online 2015 report finds search and email leading the pack with e-retailers.
Pew says Twitter is particularly popular among young adults, minorities and city dwellers.
Use of the social networking service is particularly strong among Hispanic and black adults, who are twice as likely as whites to log on to the microblogging site. 18% of black Internet users and 13% of Hispanics say they use Twitter; 5% of whites use the microblogging service.
A similar dichotomy is evident between urban, suburban and rural Internet users. 11% of urban adults, 8% of suburbanites and 5% of rural adults use Twitter, according to the survey.
Twitter users also skew young. 14% of adults 18 to 29 use Twitter, compared to 7% of those 30 to 49, 6% of those 50 to 64 and 4% of those 65 and older.
Users’ engagement with Twitter almost equally divides between those who check the site daily basis or several times a day and those who check the site infrequently or never. 36% of Twitter users log on to the site daily, while 41% check the site less than every few weeks, or never. The remaining 23% check the site for updates a few days each week or every few weeks.
