This question is only for business owners who have either hired, or thought of hiring a PR agency/consultant. What do you expect from a PR agency?
Your expectations from a PR agencies will depend on the line of business that you are in that is you will need specialist people who will guide you in the direction that business should go. It is even advantageous for you if you have haired an agency before because you know what it is like and if they under performed in any aspect of your service you are able to avoid such scenarios. On the whole I find that pr agencies are good but you must get references.
