How to Hire a PR Firm: The 90-Day Playbook

Part of Best PR Agencies in America 2026, Everything-PR's national index and agency-selection library. Updated October 22, 2026.

Direct Answer. Hiring a PR firm well takes about 90 days, run in three phases: Days 1 to 30 Define (decide whether you need an agency, scope the assignment, set the budget), Days 31 to 60 Search (build the list, write the brief, run the review), and Days 61 to 90 Decide (evaluate proposals, interview finalists, choose, and set success metrics before the first invoice). The one non-negotiable in 2026: the firm you hire must be able to measure and grow your visibility inside the AI answer engines (ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews), where buyers now research before they ever reach your site.

This page covers the process and the timeline. For how to judge the firms themselves, with the interview checklist, scorecard and reference calls, use How to Choose a PR Firm. For prices, use the PR firm cost guide.

The 90-Day Framework

Days 1 to 30: How Do You Define the Need?

Decide whether you need an agency at all. PR is a force multiplier, not a foundation. If you have nothing to say yet, an agency cannot manufacture it. Start with should you hire a PR agency, when a company actually needs a PR agency and in-house PR or agency. If the honest answer is "we need capacity, not counsel," that may be a hire, not a retainer.

Scope the assignment. Write down what the firm is actually for: earned media, executive visibility, crisis readiness, digital and influencer, GEO, reputation management. Ground it in what a PR agency does day to day, then choose the structure, agency of record or project, because it drives cost, senior attention, and institutional memory. EPR's guides to retainer vs project vs agency of record and the agency of record function compare the structures. A written PR plan turns the scope into goals and baselines.

Set the budget. Know the market rate before you issue anything, and remember that price follows scope: a monthly retainer, a one-time AI visibility audit, a GEO program, a launch project and crisis response are priced differently. A defined budget range attracts serious firms and repels the wrong ones. Anchor it to the scope, not to what you spent in 2019, and use the PR firm cost guide for the current ranges and the PR budget guide for the whole budget.

Days 31 to 60: How Do You Run the Search?

Build the list. Start from Everything-PR's national index, organized by size, specialty, and region, and the agency profiles directory. Add referrals from peers, because the referral-first method often produces a better-vetted shortlist than a cold search. Shortlist four to six firms. More than six and the process collapses under its own weight. For the terminology buyers meet, see What Is a PR Firm?

Write the brief and issue the RFP. Keep it tight: business context, scope, measurement framework, agency questions, commercial structure, and timeline. The full method is in How to Write & Evaluate a PR RFP in 2026, and the wider PR and marketing RFP archive collects the sector guides. One rule: keep the whole process under eight weeks. Longer signals indecision, and the strongest firms decline slow reviews.

How do you brief a PR agency for a product launch?

A product launch brief for a PR agency is a two-page document that states the launch date, the audience, the proof behind the claims and the result you will judge the firm by. Sending every shortlisted firm the same brief lets you compare their proposals on the same facts.

Cover eight items:

1. The launch date, which parts are fixed and which can move, and any embargo or event tied to it.
2. What the product does, who it is for, and what is new compared with what already exists.
3. The proof: customer results, test data and third-party validation, each with a named source and ready to share.
4. The audience, and the outlets, communities and AI engines where that audience looks for answers.
5. The spokespeople: who is available, when, and how much media experience each has.
6. The constraints: legal or regulatory review, competitor sensitivities and, for a public company, disclosure rules.
7. The budget range, and whether the work is a one-time project or a retainer.
8. The measures of success: coverage targets, launch-week traffic and Citation Share on a fixed set of launch-related prompts in ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews.

Give every firm the same deadline for questions and share the answers with all of them. A firm that asks sharp questions about items three and eight is showing how it will work on the account. For the longer, formal version of the same document, see the RFP guide linked above.

Ask the questions that actually filter. Ask each firm how they track brand visibility across the AI engines and what their Citation Share methodology is, who specifically will run the account, with names, titles, and hours, and for three examples of measurable outcomes with data. Vague, polished non-answers are the filter working. The full question set is in How to Choose a PR Firm.

Days 61 to 90: How Do You Decide and Onboard?

Evaluate the proposals. Score objectively before you fall for a room. Use the proposal comparison matrix and case-study verification steps in the RFP guide and the scorecard in the buyer's framework. The scorecard separates AI-era firms from agencies still selling 2018 metrics. When proposals differ in scope, compare them line by line before comparing totals.

Interview the finalists. The pitch is not the interview. Use the structured interview checklist and reference-call script in the buyer's framework to test for senior attention, category point of view, and crisis readiness. Make sure the team in the room is the team that will run the account.

Choose, then define success before the first invoice. Debrief the finalists you did not pick; it costs nothing and preserves relationships. Then, before kickoff, set the metrics: Citation Share targets, coverage benchmarks, executive-visibility KPIs, and the reporting cadence. If a firm cannot commit to measurable outcomes before day one, that is the last signal you need. EPR's guide to measuring PR ROI shows how to turn those targets into numbers a finance team accepts. For what the agency should deliver once you sign, see the guide to the PR agency first 90 days. For special cases, see hiring for a startup and choosing a crisis firm.

Check the contract before you sign. Compare the draft against the proposal clause by clause with the PR agency contract checklist. If you are replacing an incumbent, plan the exit with the checklist for changing PR agencies.
