How to Decide Which New Channel Actually Deserves a Client's Test Budget

A new advertising channel starts attracting attention. Businesses begin testing it, industry newsletters discuss its potential, and clients ask their agencies, ‘Should we get in early?’

For agencies, the challenge isn't finding new opportunities. Before performance data is available, it's determining which ones to focus on.

Prioritizing new marketing channels is more than keeping up with industry trends. Agencies should know if the channel will get them the audience they need, measurable outcomes, and enough space for their client to test.

A simple decision system can help decision teams distinguish between opportunities that look promising and experiments that are not ready for investment.

Start With the Client's Business Goal, Not the Channel

Suppose there are two clients inquiring about the same new advertising platform.

One sells software to enterprise buyers, while the other runs an online clothing business.

These opportunities may be totally different for these businesses even if the channel is developing rapidly.

First, before discussing advertising formats, or campaign ideas, determine what the client wants to achieve.

It's not until that audience acts in a manner that meets the client's goal that the channel should be considered.

This is to avoid a common pitfall: suggesting a platform because it is in trend instead of because it addresses a business problem.

The Three Questions Every Channel Must Answer

Three factors make channel evaluation easier: audience overlap, measurement maturity and minimum viable spend.

1. Is the client's audience actually there?

Having a huge user base does not guarantee an audience that will be valuable to advertisers.

A platform may have millions of users but offer limited access to a B2B client's decision makers.

Consider:

• Does the platform catch the interest of the customer's target audience?
• Are the users looking for information, finding something new or buying a product?
• Can advertisers reach relevant audience segments?
• Is the platform suitable for the client's industry?
• Are the audience new prospects or those who have been reached previously?

The final question is worthy of discussion.

When a client already has most of its audience on existing platforms, it may be a better investment to spend the capital on making the content more visible on those existing platforms than on a new platform.

Practical example: If a B2B technology firm is considering expanding to a new professional community, it could talk to the group about whether the firm's purchase decision makers are active members of the community or not, not just based on membership numbers.

2. Can the agency measure meaningful results?

A channel may seem great, but may not have the reporting features needed to make it a responsible channel for campaign management.

Prior to suggesting a test, see if the platform can support:

• Reliable impression and engagement reporting
• Website traffic tracking
• Conversion measurement
• Campaign-level performance comparisons
• Audience and placement reporting
• Exportable performance data

Advanced attribution is not needed for all campaigns. For awareness campaigns, there is good reason to cast a wide net for qualified "reach," and for lead-generation campaigns, evidence of conversion is paramount.

The key is to come up with the metrics for success in advance before going live.

When a platform does not have enough data for the client's goal, the agency should explain this limitation and not report partial results as success.

3. Is there enough room for a meaningful experiment?

The minimum viable spend is not only the smallest that a platform will allow you to put in.

It is the investment required to gather enough useful evidence to make a decision.

An agency should consider:

1. The campaign's expected audience size.
2. The likely volume of meaningful actions.
3. The number of creative variations required.
4. The time needed to observe performance.
5. The client's existing marketing commitments.

A small test may provide useful engagement or creative insights, but it may not generate enough evidence to assess a low-volume B2B conversion campaign.

The agency needs to come up with a definition before recommending the experiment: What is a feasible definition that the experiment can support?

Use a Channel Readiness Scorecard

Instead of discussing every new platform from scratch, agencies can use a repeatable scoring system.

Rate each factor from 1 to 5, where 1 represents weak suitability and 5 represents strong suitability.

Multiply each of the scores by their weights and then add them together.

For instance, if a channel scores 4, 3, 5, 3, and 4 across these factors, its weighted score is 3.8 out of 5.

This doesn't guarantee performance. It creates a consistent basis for comparing opportunities.

An agency can establish internal decision bands:

• 4.0–5.0: Strong candidate for a controlled test
• 3.0–3.9: Investigate further before committing
• Below 3.0: Keep an eye on it, don't start it yet!

They are recommended planning guidelines, not industry standards.

A channel with poor audience relevance or unreliable measurement should remain on hold, even if its overall score is reasonable.

Compare the New Channel Against Existing Opportunities

Evaluating a channel alone is incorrect.

Assume an agency runs campaigns on Google Ads and Meta Ads. A client now wants to try out a new advertising space.

The account team should consider whether there's a more beneficial result to be achieved by optimizing an existing campaign before recommending a change.

It all depends on the client's situation.

If you are looking for a new channel for an established brand with campaigns that have already been running for some time, you can find some benefit in diversification.

If there are existing channels that have measurement issues, and a small business has a hard time converting, it may be more responsible to solve those issues.

Build a Test Plan Before Launching

After passing the initial evaluation, the agency must have a written experiment plan.

A useful plan should be one page long.

A simple channel test brief

Business objective: What specific outcome should the experiment support?

Audience hypothesis: Which customer segment is expected to respond?

Channel hypothesis: Why might this platform perform differently from existing channels?

Primary success metric: What result will determine whether the test was worthwhile?

Supporting metrics: Which indicators will explain performance?

Test duration: How long will the campaign be allowed to run prior to a review?

Resource requirements: What creative, tracking and account management efforts are needed?

Decision rule: What evidence would lead you to continue, change or stop the experiment?

These details help minimize conflicts once the campaign begins.

If there is no decision rule, agencies may have to continue with underperforming experiments because stakeholders remain enthusiastic about the opportunity.

Know When to Stop, Adjust, or Expand

Not all experiments will result in a definite success or failure.

Others produce valuable returns on engagement, with relatively few conversions. Others demonstrate good success among a select few but have a difficult time scaling.

Agencies need to categorize outcomes into 3 groups.

Continue

The primary objective of the campaign is met, tracking is effective and further testing is justified.

Adjust

The audience seems relevant, but creative performance, targeting or conversion quality is poor.

Stop or pause

The platform does not reach qualified users, it doesn't provide measurement in quantity, or it regularly does not achieve the agreed success criteria.

An aborted experiment is not necessarily a wasted effort. It can prevent a client from making a larger investment based on weak evidence.

It also makes it easier to document the decision for future channel evaluations.

Make Channel Recommendations Easier to Explain

The presentation is usually brief and doesn't include all the advertising platforms.

They need a recommendation they can understand and defend.

A short channel assessment should communicate:

• What the agency investigated
• Why the channel fits or doesn't fit
• What remains uncertain
• What a reasonable experiment would establish
• What happens after the results are reviewed

This way, the choice of channels becomes a business decision instead of a marketing fad conversation.

It also aids agencies to keep the standards uniform in several client accounts.

Make Experimentation Part of a Repeatable Agency Process

New advertising avenues will continue to emerge, but agencies don't have to re-invent their assessment techniques each time.

The shared scorecard, along with the detailed test criteria and consistent reporting process makes prioritizing new marketing channels easier!

The challenge for agencies managing several accounts is to remain consistent and ensure that current campaigns are still seen.

At DM Cockpit, we aim to enable agencies to organize the workspace for digital marketing activities, client reporting, and more. Exploring how our tools can help day-to-day marketing management is a good starting point, using our agency plans and solutions.

The aim is not to endorse all the new channels. It's to make each recommendation easily defensible, measurable and actionable.

Frequently Asked Questions

1. How should agencies prioritize new marketing channels?

Agencies should compare audience relevance, business objectives, measurement capabilities, testing feasibility, and operational requirements. A weighted scorecard helps account managers evaluate opportunities consistently instead of relying on popularity or competitor activity.

2. How can an agency tell whether a new advertising channel is worth testing?

A channel is worth testing when it reaches a relevant audience, supports the client's goals, and provides enough measurement data to evaluate performance. The agency should also establish a clear hypothesis and decision criteria before launching.

3. Should smaller businesses experiment with emerging advertising platforms?

Smaller businesses can explore emerging channels when their existing marketing foundations are reasonably stable. However, improving established campaigns or fixing tracking problems may offer greater immediate value than expanding into an unfamiliar platform.

4. What is the minimum viable spend in advertising experiments?

Minimum viable spend refers to the resources needed to conduct a test that produces useful evidence. It depends on the campaign objective, expected response volume, audience size, and testing period. There is no universal amount suitable for every channel.

5. How long should agencies test a new marketing channel?

The appropriate duration depends on audience activity, conversion frequency, campaign objectives, and data availability. Agencies should set a review period before launching and avoid judging results too early when meaningful actions occur infrequently.

6. What should an agency include in a new-channel recommendation?

A recommendation should explain the business opportunity, target audience, expected benefits, measurement limitations, testing requirements, and success criteria. It should also clarify why the proposed experiment deserves attention compared with improving existing marketing activities.
