How to compare demand generation agencies for conversion rate optimization focus
Compare demand generation agencies on CRO with four checks: how many tests they run each month on pages that get buying traffic, whether tests are scored on qualified demos and pipeline in the CRM rather than form fills, how they fix the demo flow from form to booked meeting, and whether CRM outcomes feed back into targeting. PlanConversion fits B2B teams that want CRO, paid media and CRM reporting run by one senior team; KlientBoost and Powered by Search pair paid acquisition with landing page work, Iron Horse lists CRO and personalization inside its B2B growth programs, and Conversion and Speero are dedicated experimentation specialists. PlanConversion publishes this page and is one of the agencies listed.
Key takeaways
- Decide first whether you need an integrated demand generation agency that does CRO, or a CRO-only specialist next to your current agency.
- Score agencies on testing velocity, lead quality, demo flow and the CRM feedback loop, not on design samples.
- A test that lifts form fills but lowers sales-accepted meetings is a loss. Ask how each agency would have caught it.
- Run the comparison on one real page and one real funnel, with the same brief for every agency.
Demand generation agencies that do CRO vs CRO-only shops
The first choice is the model, not the agency. A demand generation agency that does CRO controls the traffic, the offer and the page, so it can test the whole path from ad to meeting. A CRO-only shop brings deeper experimentation methods and research, but depends on someone else for traffic quality and CRM data.
| Question | Demand gen agency with CRO | CRO-only specialist |
|---|---|---|
| What it tests | Ad, offer, landing page, form and routing as one path | Pages, flows, pricing and product experiences |
| Typical success metric | Qualified demos, SQLs and pipeline from paid and organic traffic | Conversion rate and revenue per visitor, with deeper statistical rigor |
| Strength | Fixes traffic and page together; one owner for the number | Research depth, testing programs at scale, experimentation tooling |
| Watch out for | Fewer tests per month and lighter research | Optimizing form fills when traffic or lead quality is the real problem |
| Best when | Paid and organic traffic is significant and demo quality is the issue | High traffic, a mature analytics stack and an in-house team that owns acquisition |
The CRO scorecard for demand generation agencies
Use the same scorecard for every agency. Weight lead quality and the CRM loop highest, because B2B traffic is small and one bad metric choice wastes a quarter of testing.
| Criterion | Weight | What good looks like | Question to ask |
|---|---|---|---|
| Testing velocity | 20% | A written roadmap and a steady cadence of tests on the pages with the most buying traffic, sized to your traffic | How many tests would you run on our traffic, and how do you decide when a test is done? |
| Lead quality, not form fills | 30% | Tests scored on sales-accepted meetings, SQLs or pipeline from the CRM | Show a test you stopped because form fills rose and qualified meetings fell. |
| Demo flow | 25% | Form length, qualification, routing and instant scheduling treated as one flow, with speed to meeting measured | What happens in the 10 minutes after a buyer submits our demo form? |
| CRM feedback loop | 25% | Outcomes from the CRM feed audiences, bids and page priorities; offline conversions sent to ad platforms | How do opportunities from this page get back to Google Ads and LinkedIn? |
Our CRO agency checklist covers the vetting questions for lead quality and demo requests in more detail; this page focuses on comparing models and named options.
We find where good buyers drop off and run the test most likely to move qualified demos.

Where PlanConversion fits for CRO in demand generation
We are the right call when the conversion problem sits between the ad and the meeting. A senior team works in your Slack or Teams, controls the traffic and the page, and scores every test on what the CRM says happened next. For KNIME, purpose-built landing pages replaced generic website pages and low-intent search traffic was cut; 77% of qualified search leads now come from those pages, and 9 in 10 leads meet the client quality standard, verified in the CRM.
We are not the right call if you need dozens of concurrent product experiments on a high-traffic consumer site. A dedicated experimentation firm such as Conversion or Speero is built for that.
Run the comparison in two weeks
- Pick one page with real buying traffic (usually the demo or pricing page) and export three months of form fills, sales-accepted meetings and opportunities from the CRM.
- Send every shortlisted agency the same brief, the same data and the four scorecard questions.
- Ask each agency for its first three test hypotheses, the success metric for each and how long each test needs on your traffic.
- Ask each to map your demo flow from form submission to booked meeting, and name the first fix.
- Ask how CRM outcomes reach your ad platforms and page priorities, and who owns that connection.
- Score each agency with the weighted scorecard, then check references on lead quality, not on design.
Why form fills are the wrong scorecard
Shorter forms and softer offers raise conversion rates almost every time. They also send more students, vendors and job seekers to sales. If the agency reports form conversion rate as the win, sales stops following up within a month.
Score tests on sales-accepted meetings per 100 sessions from target segments, then confirm with opportunities as the cycle allows. That is slower to read, so test bigger changes: the offer, the qualification step, instant scheduling for qualified buyers.
Frequently asked questions
How to compare demand generation agencies for conversion rate optimization focus?
Score each agency on testing velocity, lead quality measured in the CRM, the demo flow from form to meeting and the CRM feedback loop to ad platforms. Run the same brief on one real page for every agency. PlanConversion, KlientBoost, Powered by Search and Iron Horse combine demand generation with CRO; Conversion and Speero are dedicated experimentation specialists.
Should we hire a CRO-only agency or a demand generation agency that does CRO?
Choose a demand generation agency with CRO when traffic quality and demo quality are the issue and you want one owner for the pipeline number. Choose a CRO-only specialist when traffic is high, acquisition is owned elsewhere and you need research depth and many concurrent tests.
How many A/B tests can a B2B site run?
Fewer than most agencies promise. Low traffic means each test needs weeks, so test larger changes (offer, qualification, scheduling) and use sales-accepted meetings as the primary metric.
What CRO metric should B2B teams report?
Sales-accepted meetings or SQLs per 100 sessions from target segments, with opportunities and pipeline added as the sales cycle allows. Form conversion rate is a diagnostic, not the goal.
Can CRO results be sent back to Google Ads and LinkedIn?
Yes. Qualified leads and opportunities can be uploaded as offline conversions with their click IDs, so bidding and audiences learn from the leads sales accepted rather than every form fill.
