Acquisition Channels — Evaluating and Selecting Marketing Channels

This playbook covers how to systematically evaluate and select acquisition channels for any B2B company. This framework has been used to systematically identify winning channels and dramatically increase lead generation.

Core Principle: Every Company Is Different

The most dangerous thing a marketer can do is assume that what worked at their last company will work at the new one. Senior marketers who can't adapt their tactics accordingly fail repeatedly.

Go into every new company with a blank slate. What matters is:

• Your willingness to learn the new market
• Your creativity in finding where your buyers are
• Your experimental mindset to figure out what works here
• Your discipline to measure and optimize

The Channel Audit Framework

Step 1: List All Potential Channels

Start broad. Include every conceivable channel:

Channel	Type	Typical B2B Fit
Email marketing	Owned	Almost always #1 for B2B
LinkedIn Ads	Paid	Strong for professional targeting
Google Ads (Search)	Paid	Great for intent-based demand
Google Ads (Display/Retargeting)	Paid	Best for retargeting, not prospecting
Facebook/Meta Ads	Paid	Custom audiences for niche B2B
Events/Trade shows	Offline	High-touch, quality pipeline
Webinars	Owned	Leading pipeline driver when done right
Content/SEO	Owned	Long-term compounding returns
ABM sequences	Outbound	High-value target accounts
Partnerships/Referrals	Earned	High quality, low cost
Direct mail	Offline	Stand out in digital noise
Content syndication	Paid	High volume, often low quality
Community/Social organic	Owned	Brand building, long play
PR/Media	Earned	Credibility and awareness
In-product messaging	Owned	Existing user base expansion
TikTok Ads	Paid	Short-form video reach, works for some prosumer and SMB B2B
Publications	Paid	Industry newsletters and trade publications reach engaged niche audiences
Reddit Ads	Paid	Subreddit-level targeting for technical and specialist audiences

Step 2: Validate Audience Size

Go into each platform and determine your actual audience size:

LinkedIn:

• Use Campaign Manager's audience builder
• Input your persona criteria (title, industry, company size, geography)
• Note the estimated audience size

Google Ads:

• Use Keyword Planner for search volume
• Test keywords with Ad Preview tool to see what actually appears
• Note monthly search volume for your key terms

Facebook:

• Use Audience Insights with your custom audience
• Check Matched Audience size (minimum 300 contacts for LinkedIn, more flexible for Facebook)

The Reality Check: If your total addressable audience on a platform is 500 people, you need a fundamentally different strategy than if it's 500,000. A niche B2B product targeting 2,000 prospects nationally can't run broad awareness campaigns — it needs surgical targeting.

Step 3: Assess Feasibility

For each channel, evaluate:

Criteria	Question	Weight
Audience fit	Are your buyers actually here?	High
Budget	Can you afford to test meaningfully?	High
Creative requirements	Do you have the content/creative?	Medium
Team capacity	Can your team execute on this channel?	Medium
Measurement	Can you track ROI clearly?	High
Timeline	How long until you see results?	Medium
Competition	Are competitors already saturating this?	Low

Step 4: Create ROI Hypotheses

Before spending a dollar, estimate what you expect:

Channel: LinkedIn Ads
Monthly Budget: $5,000
Expected CPL: $100 (based on industry benchmarks)
Expected Leads: 50
Expected MQL Rate: 25%
Expected MQLs: 12-13
Expected Pipeline Value: $150,000 (at $12K avg deal)
Expected ROI: 30:1 pipeline-to-spend

Do this for every channel you're considering. Rank by expected ROI.

Step 5: Prioritize and Experiment

Select 3-4 channels for initial testing. Run each for at least 60-90 days before evaluating — shorter periods don't produce statistically significant data.

Experiment cycle:

1. Launch with initial hypothesis
2. Run for minimum viable period
3. Measure against hypothesis
4. Adjust targeting, creative, budget
5. Re-run for another cycle
6. Decide: double down, maintain, or kill

Channel-Specific Insights

Email: Almost Always #1

Email is the primary acquisition channel for most B2B companies because:

• Near-zero variable cost
• Strong conversion rates from email to webinar registration
• You own the channel (no algorithm changes)
• Scales with your list size

Start building your email list on day one. Every lead from every channel should enter your email nurture.

LinkedIn: Best B2B Paid Channel (When Done Right)

LinkedIn is often the best advertising platform for B2B, but only when:

• Targeting is specific and intentional (not just "marketing managers")
• Creative is personable and connects with users (not generic corporate)
• You brainstorm demographic segments before launching
• You run multiple experiments and double down on winners

Results benchmark: 1550% increase in LinkedIn lead gen is achievable by replacing agency-run generic campaigns with targeted, creative campaigns.

LinkedIn CPE has decreased in recent years, making it more viable now than it was.

Google Ads: Intent-Based, Not Awareness

Google Ads works for B2B when targeting keywords that match actual search intent:

• Do: Target keywords that prospects actually search (e.g., "clean up Salesforce" not "Salesforce documentation")
• Don't: Bid on broad keywords that are technically related but used by non-buyers
• Test: Use the Ad Preview and Diagnosis Tool before adding keywords

You can often significantly reduce Google Ads spend while producing better results by focusing on the right keywords instead of broad agency-selected terms.

Use top-converting paid keywords to inform your organic SEO strategy. If "clean up Salesforce" converts at 8% in paid, write content targeting that keyword organically.

Events and Trade Shows: High-Touch Pipeline

Events produce fewer leads but those leads often close at higher rates because of personal connection. Every event needs:

• Pre-show outreach to target attendees
• Post-show follow-up sequence within 48 hours
• Full ROI tracking with dashboards tracking leads, pipeline, and revenue

Webinars: Sleeper Pipeline Driver

Webinars can grow from 30 registrants to 200+ at peak when properly promoted. They're often the leading pipeline driver, contributing significant pipeline value. The key is multi-channel promotion: email as primary, LinkedIn as secondary, sales team sharing, and in-product messaging.

Content/SEO: Compound Interest

SEO is a long game but compounds over time. One caveat: website architecture can break your SEO strategy regardless of how good your content is. If your site structure doesn't support proper crawling and indexing, no amount of content will rank.

Strategic Channel Selection: Where They Aren't

The Competitive Gap Strategy

Instead of fighting competitors on their home turf, look for underserved markets:

Rural and underserved markets:

• Less competition, lower CAC
• Buyers are underserved and grateful for attention
• Often overlooked by competitors focused on urban/enterprise accounts
• This becomes a brand story you can own ("We care about communities others ignore")

Niche verticals:

• Small segments that large competitors can't justify pursuing
• Higher switching costs once you're established
• Opportunity to become the dominant brand in that niche

Geographic expansion:

• International markets where competitors haven't expanded
• Regions with different buying seasons (southern hemisphere, for example)
• States or provinces where competitors have no presence

Market Segmentation by Budget

Tier your approach:

• Large accounts (85% of industry revenue): ABM approach, long sales cycles, white-glove
• Mid-tier accounts (sweet spot): Balanced approach, scalable campaigns
• Small accounts (15% of revenue): Programmatic, self-serve where possible

Measuring Channel Performance

Monthly Channel Scorecard

Channel	Spend	Leads	CPL	MQLs	Pipeline	Won Revenue	ROI	Status
Email	$500	100	$5	30	$300K	$80K	160x	Scale
LinkedIn	$5K	50	$100	15	$200K	$40K	8x	Maintain
Google	$3K	15	$200	3	$50K	$0	-1x	Review
Events	$10K	25	$400	10	$250K	$100K	10x	Selective

Decision Framework

Performance	Action
ROI > 5x and scaling	Increase budget 25-50%
ROI > 3x, stable	Maintain and optimize
ROI 1-3x	Test new creative/targeting for 60 days
ROI < 1x for 90+ days	Kill or reduce to minimum test budget

The Experimental Mindset

The best growth marketers maintain a portfolio approach:

• 60% of budget — Proven, high-ROI channels
• 25% of budget — Channels showing promise, being optimized
• 15% of budget — New experiments and tests

This ensures you're always discovering the next winning channel while protecting your proven pipeline sources.

Common Channel Selection Mistakes

1. Relying on past experience — "LinkedIn worked at my last company" means nothing
2. Following competitors — Just because they're on a channel doesn't mean it works for them
3. Not validating audience size — Spending on a platform where your audience doesn't exist
4. Too many channels at once — Better to do 3 channels well than 8 channels poorly
5. Killing channels too early — Most channels need 60-90 days of data to evaluate
6. Not tracking ROI to revenue — Leads are meaningless without pipeline and closed-won attribution
7. Ignoring organic channels — Email and SEO are "free" and often outperform paid
8. Not experimenting continuously — The channel landscape changes; what doesn't work today might work in 6 months
