How to Choose a PR Agency

How to brief a public relations agency, what earned media can and cannot promise, and the questions that reveal whether relationships are real.

Public relations is the agency category where expectations go wrong most often. Coverage cannot be bought, timelines are governed by other people's news cycles, and the most valuable outcomes are frequently the ones that are hardest to count.

Decide what you are buying

Public relations covers several distinct jobs. Naming yours before you brief will save a wasted quarter.

  • Media relations: sustained coverage in trade or national outlets.
  • Launch support: a concentrated push around a product, funding round or opening.
  • Thought leadership: bylines, commentary, speaking and awards for named executives.
  • Analyst and industry relations: relevant in B2B and technology.
  • Crisis and issues management: retained readiness rather than campaign work.

An agency that is excellent at trade media relations in your sector may be a poor fit for consumer launch work, and vice versa.

Questions that reveal real relationships

  • Which publications and journalists have you placed in this sector in the last twelve months? Ask for links, not logos.
  • Who will pitch on our behalf, and how long have they covered this beat?
  • What is your view on our story right now? A serious agency will tell you which parts are newsworthy and which are not.
  • What do you need from us to work? Expect specific asks: executive availability, data you can publish, customer permission, a fast approval chain.
  • How do you handle a quarter with little news? The answer tells you whether they can create angles or only amplify announcements.

Measurement without vanity metrics

Advertising value equivalency is not a credible measure and reputable practitioners have moved away from it. Agree instead on a short set of measures before work starts: coverage in a named target list, share of voice against named competitors, message pull-through, referral traffic and branded search movement, and inbound opportunities that cite a placement.

Ask how each will be collected and who reports it. Coverage volume alone rewards low-quality placement.

Contracts and expectations

Most PR work is retained monthly with a three to six month minimum, because relationships and pipeline take time. Be explicit about:

  • Guaranteed activity versus guaranteed outcomes. Any agency guaranteeing specific placements in specific outlets is describing paid placement, which must be disclosed as advertising.
  • Exclusivity within your competitive set.
  • Ownership of the media list and the pitch materials.
  • Notice periods and what happens to work in flight.

Warning signs

  • Guaranteed coverage in named publications.
  • A pitch built on logos of outlets rather than named journalists and dated links.
  • Undisclosed paid placement or syndicated wire pickups presented as earned coverage.
  • No questions about legal, regulatory or spokesperson constraints in your business.
