Marketers and advertising execs plan to continue the recent string of hiring, saying they are more likely to add staff in the coming quarter than in the previous, according to a new survey by the Creative Group, an industry-specialized staffing agency.

Based on more than 250 phone  interviews with executives at marketing organizations and advertising agencies, 22% of them plan to hire in the coming months – up from 15% at the beginning of the year.

Twenty-six percent of these companies expect to fill positions in web design and production, with social media coming in second at 25%, and PR and account services tying for third with 24%. Copywriters are least likely to be hired, with only 8% of executives saying they plan to fill these positions.

The boom is a result of more creative projects being undertaken by agencies and firms, said Lara Dodo, regional VP of the Creative Group. “[Online focused] candidates…are in particularly strong demand among companies of all sizes and industries, to help with online and digital initiatives.”

More than 50% of respondents added that it was challenging to find skilled creative professionals, meaning qualified applicants could be in high demand.

The survey also assessed business confidence, with 86% (an increase from 82% three months ago) saying they are somewhat or very confident in their firms’ prospects for growth.
