How to Choose a B2B PPC Agency

Choosing a B2B PPC agency is one of the more consequential marketing decisions a B2B company makes. The agency you select gets direct access to your ad budget, your brand messaging, and your pipeline data. A bad choice wastes money and sets your program back 12 to 18 months. A good choice builds a scalable paid media program that compounds over time and becomes a reliable pipeline source.

This guide walks through a structured process for evaluating and selecting a B2B PPC agency: what to look for, what questions to ask, how to evaluate proposals, and what red flags should make you walk away. It applies whether you are hiring your first PPC agency or replacing one that has not delivered.

Define What You Need Before You Start Looking

Before you contact a single agency, define your requirements. What channels do you want managed: Google Ads only, Google plus LinkedIn, all three major platforms? What is your monthly ad spend budget? What is your target cost per lead? What does a qualified lead look like to your sales team, including company size, job title, and deal size? What CRM do you use and are you expecting the agency to connect campaign data to it? What does success look like in 90 days, in 6 months, in 12 months?

Without clear answers to these questions, you will evaluate agencies against vague criteria and make a selection based on who presents the best pitch rather than who is best positioned to deliver what you actually need. Agencies that are good at closing new clients are not necessarily good at managing B2B PPC. The best agencies are often the ones who ask you the hard questions upfront rather than agreeing with everything you say.

Create a Shortlist of B2B PPC Agency Candidates

Use multiple sources to build your initial shortlist. Clutch, UpCity, and GoodFirms provide curated directories of PPC agencies with client reviews. Search for agencies that have specific B2B client portfolios and reviews from companies in your industry or adjacent industries. Ask for referrals from peers in your network who have worked with B2B PPC agencies. Your own observation of which agencies are advertising competently on the keywords you want to own is also useful: agencies that cannot run their own PPC campaigns effectively have a credibility problem.

Narrow your list to three to five agencies that specialize in B2B lead generation rather than general digital marketing. Specialist agencies consistently outperform generalist agencies on B2B PPC work because the playbook is different and the experience accumulates differently. A PPC agency with 80 percent of their client base in B2B has been exposed to patterns across many B2B accounts that a generalist agency simply has not seen.

What to Evaluate in an Agency Discovery Call

The discovery call tells you a lot about an agency’s quality. Agencies that spend the first 30 minutes of a discovery call selling their services rather than asking questions about your business are not oriented toward understanding before recommending. The best agencies spend the majority of discovery calls asking: What does your sales team say about current lead quality? What has worked in PPC before? What did not work? What does your best customer look like? What are the main objections your sales team hears?

Listen for specificity. When you ask how they handle B2B lead quality, do they give a specific answer about CRM integration, lead scoring, and feedback loops with your sales team? Or do they give a vague answer about “aligning marketing and sales”? Vague answers signal generic thinking. Specific answers signal operational experience.

Ask them to explain a specific optimization they have made for a B2B client that produced a meaningful result. The answer should describe a specific problem they identified, the data that revealed it, the change they made, and the outcome they measured. Generic descriptions of “optimizing bids and keywords” are not evidence of expertise. A specific story about diagnosing a conversion tracking error that was inflating CPL by 40 percent and fixing it is evidence of expertise.

How to Evaluate Proposals

A strong B2B PPC agency proposal includes specific keyword research examples for your category, a proposed campaign architecture with rationale for the structure, a clear description of the platforms and budget allocation they recommend and why, landing page recommendations or plans, a conversion tracking setup plan, and a defined reporting structure with specific metrics and cadence.

A weak proposal describes what PPC is, lists the agency’s platform certifications, and promises to “drive more qualified leads” without showing any evidence that they have thought specifically about your market, your buyer, or your competitive landscape. Weak proposals get recycled across dozens of prospects with minimal customization. You can usually tell by whether the keyword examples and campaign structure recommendations are actually relevant to your specific business.

Compare proposals on specificity, not length. A four-page proposal with specific keyword research, a concrete campaign architecture, and a realistic outcome model is more useful than a 25-page proposal full of generic PPC statistics and platform descriptions. You are buying their thinking and execution capability, not their PowerPoint production quality.

Checking References

Reference checks are the most underused tool in agency selection. Agencies are eager to provide references, but most buyers ask generic questions that produce generic answers. Ask reference clients specific questions: How did the agency handle a campaign that was not performing? What did they do when lead quality was poor? Did the campaigns actually contribute to closed revenue, and if so, how do you know? Would you rehire them if you started this engagement fresh today?

Ask for references from B2B clients specifically. A reference from a consumer brand is not relevant to your B2B evaluation. Ask for references from clients in your deal size range. An agency’s results for a company doing million in revenue are not necessarily transferable to a company doing million in revenue. And ask for references from clients who have been with the agency for at least 12 months, because the first 90 days of any engagement are about setup and learning, not results.

Contract Terms to Review

Account ownership: confirm that your Google Ads, LinkedIn Ads, and Microsoft Ads accounts are owned by your company and accessible to you at all times. Some agencies create accounts under their own management hierarchy without giving you full administrative access. That is a risk you should not accept.

Data ownership: confirm that all campaign data, keyword research, ad copy, and landing pages created during the engagement belong to you if you leave. Some agencies treat these as proprietary assets and remove access when a client departs. That is not acceptable for any work product created with your budget.

Notice period: standard agency contracts require 30 to 60 days notice to terminate. Anything longer than 60 days is excessive for a monthly services engagement. Read the termination clause carefully before signing.

Performance expectations: if the agency commits to specific performance targets in the proposal, ensure those commitments are written into the contract. Verbal promises that do not appear in the contract are worth nothing at review time.

Making the Final Decision

After discovery calls, proposals, and reference checks, the decision usually comes down to two or three agencies that are all technically qualified. At that point, trust your judgment about the working relationship. B2B PPC is an ongoing collaboration. The agency needs to understand your sales process, stay current on your competitive landscape, and communicate clearly when things are not working. An agency you can have honest, data-driven conversations with will produce better results over 12 months than an agency you are slightly uncomfortable challenging.

If everything else is equal, choose the agency that asks the hardest questions rather than the one that agrees with everything you say. The agencies that push back on your assumptions are the ones who will tell you when a campaign is not working instead of hiding it in a favorable chart.

Frequently Asked Questions

How many agencies should I evaluate when choosing a B2B PPC agency?

Evaluate three to five agencies for most B2B PPC searches. Fewer than three limits your ability to benchmark quality and pricing comparisons. More than five creates decision fatigue without meaningfully improving the quality of your selection. Build your shortlist from review platform research, peer referrals, and your own observation of which agencies are advertising effectively on your target keywords. After initial discovery calls, narrow to two or three finalists for full proposals. The proposal stage is where you invest significant evaluation time, so limiting finalists to the highest-quality candidates from the discovery stage is worth the filtering effort.

How long should I give a B2B PPC agency before evaluating results?

Evaluate on a 90-day initial review with clear expectations set at the start of the engagement. The first 30 days of a new B2B PPC engagement are primarily setup: campaign architecture, keyword research, landing page alignment, and conversion tracking configuration. Days 30 to 60 produce the first wave of campaign data and initial optimizations. Days 60 to 90 are where meaningful optimization begins based on real performance data. Evaluating results at 30 days is premature. Evaluating at 90 days gives you a complete picture of campaign mechanics, initial conversion performance, and whether the agency’s optimization process is functioning correctly.

What are the biggest mistakes B2B companies make when choosing a PPC agency?

The most common mistakes are selecting based on price rather than fit, not defining success metrics before starting the engagement, choosing a generalist agency rather than a B2B specialist, failing to check references specifically from B2B clients, and not verifying account ownership terms before signing. Secondary mistakes include evaluating agencies on their presentation quality rather than their operational rigor, not asking who specifically will manage the account day-to-day, and underestimating how important landing pages are to PPC performance and not scoping them into the engagement from the start.

Should I tell competing agencies what other agencies I am evaluating?

You do not need to disclose which other agencies you are evaluating. Keeping your shortlist private prevents agencies from gaming their proposals based on competitor positioning rather than genuine strategic thinking. It also removes the risk of agencies pressuring you with artificial urgency based on competitor timelines. The exception is if you want to ask an agency directly how they compare to a specific competitor you are seriously considering. A confident agency will engage that question honestly. An agency that refuses to compare itself to competitors or dismisses them without substance is revealing something about their competitive confidence.

What should I do if my current B2B PPC agency is underperforming?

Before replacing your current agency, have a direct conversation about what is not working and what you expect to see change in the next 60 days. Give them a specific improvement target: a CPL reduction of 20 percent, a lead quality score improvement measured by sales team feedback, or a conversion rate improvement on a specific landing page. Set a timeline and evaluate against it. If they cannot articulate a clear plan for hitting the target or if the improvement does not materialize, that is the point to start evaluating alternatives. Document your performance expectations in writing before having the conversation so both sides have a clear record of what was agreed.
