To choose a good PPC agency, ask questions that force it to explain method: what it will fix in your tracking before changing bids, which conversion it will optimize toward, who will work your account, and how you will know if it is not working. Then confirm you will own every account, and pick a fee model that rewards the outcome you want. The agency whose answers are most specific is usually the one whose work will be most specific.
This guide gives you the questions to ask a PPC agency with the answers to listen for, explains what separates a top tier agency from a standard one, covers how to choose a PPC remarketing service, and lays out the first 30 days, the fee models, and the red flags.
What a PPC agency actually does.
A PPC agency (pay-per-click agency) plans, builds, and manages paid advertising where you pay per click or per result: Google Ads search, Shopping and Performance Max, Microsoft Advertising, paid social on Meta, and marketplace ads such as Amazon Sponsored Products. The visible work is keywords, ads, and bids. The work that decides results is less visible: conversion tracking, conversion definitions, landing pages, offline conversion import from your CRM, and reporting that ties spend to revenue.
Most evaluations go wrong because pitches are optimized for the pitch. Every agency shows a return on ad spend chart going up and to the right. None of that predicts how it will behave inside your account. Questions that require method, not adjectives, do.
Questions to ask a PPC agency.
Ask these in the first or second meeting. Each includes what a strong answer sounds like, because the questions only work if you know what you are listening for.
- What will you change in the first two weeks, before you touch a bid? Strong answer: a conversion tracking audit, GA4 and Google Tag Manager review, agreed conversion definitions, and a baseline. Weak answer: new keywords and ad copy.
- Which conversion will the campaigns optimize toward, and why? Strong answer: a discussion of lead quality, sales cycle, and offline conversion import from your CRM. Weak answer: form fills and calls.
- How do you handle conversions the platform claims that our CRM never sees? Strong answer: deduplication, click ID capture, and reporting from the CRM or store. Weak answer: platform numbers are accurate.
- Show me an account you restructured and explain why the old structure was wrong. Strong answer: a specific story about match types, consolidation, or budget fragmentation. Weak answer: a slide with a percentage on it.
- What is your position on Performance Max and broad match for an account like ours? Strong answer: the conditions under which each helps or hurts, and how they would test it. Weak answer: blanket enthusiasm or blanket refusal.
- Who will log into our account, and how often? Strong answer: names, roles, and a cadence. Weak answer: our team.
- How often do you review search terms and add negatives? Strong answer: a set cadence with examples of exclusions they would expect in your industry.
- Whose login owns the ad accounts, pixels, and tag container? Strong answer: yours, with the agency linked as a manager. Anything else is a problem.
- How does your fee change if we cut spend in half? Strong answer: a clear explanation that does not punish you for spending less.
- What does your report look like in a bad month? Ask to see one. An agency that has never had a bad month is new or editing.
- How will we know if it is not working, and what happens then? Strong answer: a defined review point, criteria, and willingness to pause or reduce spend.
- How do you coordinate with our website, CRM, and sales team? Strong answer: landing page ownership, a lead quality feedback loop, and named contacts on both sides.
- What would you not recommend for us? Strong answer: a channel or tactic they think is wrong for your business, with reasons.
- What is the notice period, and what do we keep at exit? Strong answer: weeks of notice, and everything stays in your accounts.
- How do you run remarketing, and how do you know it is incremental? Strong answer: exclusions, frequency limits, and a holdout or geo test (see the remarketing section below).
What separates a top tier PPC agency from a standard one.
Most standard agencies are competent at the platform. The difference at the top is everything around the platform.
| Area | Standard agency | Top tier agency |
|---|---|---|
| Optimization target | Platform-reported conversions | Qualified leads, sales, or revenue imported from the CRM or store |
| Tracking | Uses whatever tags exist | Audits and rebuilds tracking first, adds server-side tracking where browser loss is material |
| Reporting | Dashboard of platform metrics | A short readout reconciled to the CRM, with what changed and why |
| Account structure | Template reused across clients | Built around your margins, services, and locations |
| Landing pages | Out of scope | Tested and changed as part of the work |
| Staffing | Pitched by seniors, run by juniors | Named people who stay on the account |
| Fee model | Percentage of spend with no link to return | Flat or hybrid fee tied to agreed outcomes |
| Ownership | Accounts sometimes built in the agency's name | Run for you or with your team, documented either way |
The single clearest separator is offline conversion import. An agency that sends closed deals, booked jobs, or qualified leads back into Google Ads and Meta is training the algorithms on what makes you money. One that does not is training them on form fills, including the spam ones.
Choosing a PPC remarketing service.
Remarketing (also called retargeting) shows ads to people who already visited your site, engaged with your content, or are on your customer list. It is easy to set up and easy to overstate, because the people it targets were already likely to come back. When you evaluate a remarketing service, check these:
- Audience definitions: separate audiences for product viewers, cart abandoners, pricing page visitors, and past customers, with sensible membership durations for your buying cycle.
- Exclusions: recent converters and existing customers excluded unless there is a deliberate cross-sell, so you are not paying to show ads to people who just bought.
- Frequency limits: a cap on how often one person sees ads, so remarketing does not become the reason someone unsubscribes from your brand.
- Consent and data: audiences built with consent mode and your privacy policy in place, and Customer Match lists uploaded under the platform's policies.
- Incrementality: a holdout group or geographic test that shows whether remarketing produces sales that would not have happened anyway.
- View-through caution: reporting that separates click-through from view-through conversions, since view-through credit inflates remarketing results most of all.
What the first 30 days should look like.
Fee models, channel specialists, and red flags.
Fee structure shapes behavior. A percentage of spend rewards growing the budget; a flat retainer rewards predictability; a pure performance fee rewards hitting the number, sometimes with loose conversion definitions; a base fee plus bonus shares upside when the outcome is measured cleanly. In our experience a flat or hybrid fee with a defined scope produces the fewest surprises.
Channel matters too. If you sell on Amazon, Sponsored Products, Sponsored Brands, and Sponsored Display are a different discipline from Google Ads, with their own bidding, search term harvesting, and profitability math tied to fees and inventory. Ask whether the agency runs Amazon accounts day to day, or look for a specialist in Amazon PPC management.
- Reporting that leads with clicks, impressions, or click-through rate instead of the agreed conversion.
- Reluctance to give you administrative access to your own accounts.
- Promises of results before anyone has looked at your tracking.
- Long contracts with early termination penalties.
- The same campaign template for every client regardless of industry.
- Resistance to offline conversion tracking, usually framed as a CRM problem rather than a campaign problem.
“The fee model tells you what the agency will want to be true at the end of the month. Choose the one where what they want and what you want are the same thing.”
Where the platform stops and the work begins.
Google Ads, Microsoft Advertising, and Meta will all spend a budget efficiently toward whatever you define as success. Choosing a PPC agency is really choosing who defines success, who builds the tracking that measures it, and who owns the data afterward. Run three agencies through the same questions, ask each for a written 30-day plan and a bad-month report, and pick the most specific. That measurement-first approach is how Theory Road runs paid media, and we are happy to be asked every question on this list.
How do I choose a good PPC agency?
Ask questions that require method: what it will fix in tracking before changing bids, which conversion it optimizes toward, who works the account, and how you will know if it is failing. Require that you own every account, ask for a written 30-day plan and a sample bad-month report, and choose the agency with the most specific answers.
What questions should I ask a PPC agency?
Ask what it will change in the first two weeks, which conversion it will optimize toward, how it reconciles platform conversions with your CRM, who logs into the account and how often, how its fee changes if spend drops, what its reports look like in a bad month, and what you keep when the contract ends.
What separates a top tier PPC agency from a standard one?
A top tier agency optimizes toward revenue or qualified leads imported from your CRM or store, rebuilds tracking before scaling spend, reports a short readout reconciled to your own systems, keeps named senior people on the account, and builds everything under your ownership. A standard agency is often competent in the platform but optimizes toward platform-reported conversions.
What should I consider when choosing a PPC remarketing service?
Check audience definitions and membership durations, exclusions for recent buyers, frequency limits, consent handling, and whether reporting separates click-through from view-through conversions. Most important, ask how the service proves remarketing is incremental, ideally with a holdout group or geographic test rather than platform-attributed sales alone.
Should a PPC agency specialize in my industry?
Industry experience helps with search term intuition and offer design, but method matters more. An agency with strong measurement discipline learns a new vertical faster than an industry specialist fixes weak tracking. Ask about both, and weight tracking, conversion definitions, and reporting practice more heavily than a logo slide.
