The issue caused a storm in the blogosphere last week, after the Blog Till You Drop site revealed how one blogger had been offered cash to write about a PR campaign.
This week's poll found a small majority of PR professionals agreeing that bloggers should not operate on such a 'pay per play' basis.
But a significant minority (43 per cent) believed that it was acceptable for bloggers to accept such payments. More than 100 PR professionals voted on the poll.
Robin Grant, MD of We Are Social, said: 'Bloggers are their own people and should write what they want. The results of the PRWeek poll only show the naivety towards social media in the PR industry; they haven't got their heads round it and aren't set up for it.'
Fernando Rizo, head of digital, Ketchum London, said: 'Should Ketchum London ever pay a blogger with-out being completely transparent, I will fall on my sword.'
Michelle McGlocklin, MD, technology practice, Weber Shandwick, said: 'I don't think it's right to say that PR professionals should never be allowed to pay bloggers.
'They just need to carefully weigh up whether what they're doing creates any real value.'
