So you don't see the value of having interviews with, or comments from, "real eBid users" or perhaps involving the loyal users in the promotion of the site?
If the PR company merely produce pieces which do not actually include the input of any eBid users, how long do you think it'll be before someone else notices and uses that against eBid?
"Daily Blog News: eBid employed XYZ PR Firm of London to produce their latest advert but gave strict instructions not to actually ask the users of their site for their opinions. Why do you think that is, folks?"
A little bit of positive interaction can go a long way, not just for use in advertising, but also in building up user satisfaction, loyalty and confidence.
