Different channels reach people at different awareness stages. Your job is to map which channels reach which stages, so you can start right (most aware) and work left (less aware) systematically.
Most aware channels (product-aware to most aware): Google search for your brand name or competitor names ("Guardey pricing", "Guardey vs Knowbe4"). Remarketing to people who visited pricing or demo pages. Referrals from existing customers. G2 or Capterra profiles where they're actively comparing. These people are 80-90% ready to buy.
Solution-aware channels (solution-aware to product-aware): Google search for solution categories ("security awareness training", "phishing simulation"). LinkedIn ads targeting job titles who need this solution. Industry publication advertising where they're researching solutions. Content marketing (guides, webinars) for people actively researching. These people are 50-70% ready, need vendor comparison and proof.
Problem-aware channels (problem-aware to solution-aware): Content marketing explaining why the problem matters. Organic search for problem-related terms ("why do employees click phishing emails"). Cold outbound to people whose role implies they have the problem. LinkedIn thought leadership raising awareness. These people are 20-40% ready, need solution education.
Unaware channels (unaware to problem-aware): Broad LinkedIn campaigns. Conference sponsorships. PR and media coverage. Cold outbound to people who might have the problem but don't know it. These people are 0-20% ready, need problem education before anything else.
Start at the top of this list (most aware) and work down as you hit limits. Don't start at the bottom because it's cheaper to reach people.
Bottom-of-funnel traffic (competitor searches, high-intent keywords) has high cost per click but high conversion rates. Top-of-funnel traffic (cold outbound, broad LinkedIn ads) has low cost per click but low conversion rates. The question is: which has better cost per customer?
Example: Google search for "Guardey vs Knowbe4" costs £5 per click (expensive). But 30% of clickers book a demo because they're actively comparing and ready to buy. 30% demo rate × 50% close rate = 15% of clicks become customers. So £5 CPC ÷ 0.15 = £33 per customer in ad spend. Add demo cost (sales rep time) and total CAC might be £500.
Example: Cold LinkedIn ad to security directors costs £2 per click (cheap). But 2% book a demo because most aren't in buying mode. 2% demo rate × 30% close rate (lower because they're less ready) = 0.6% of clicks become customers. So £2 CPC ÷ 0.006 = £333 per customer in ad spend. Add longer sales cycle (more touches needed) and total CAC might be £2,000.
The expensive traffic (£5 CPC) delivered lower CAC (£500) than the cheap traffic (£2 CPC and £2,000 CAC). This is why you start right and work left. Expensive clicks from ready buyers beat cheap clicks from cold prospects.
The limit: bottom-of-funnel traffic is small. Only so many people search "Guardey vs Knowbe4" each month. Once you've dominated that, you must work left to warmer and eventually colder traffic. But starting right gives you profitable revenue fast, which funds the longer-term cold traffic plays.
You'll know you've maxed out a channel when: volume flatlines despite increased budget (you're reaching everyone already), cost per click rises significantly (you're bidding against yourself or competition increased), conversion rates drop (you've creamed the hottest prospects, now reaching less ready people), or you've reached 80%+ impression share (limited room to grow).
When you hit these limits on bottom-funnel channels, shift left to the next awareness stage. You've dominated competitor comparison searches, now expand to solution category searches. You've maxed remarketing to demo page visitors, now add remarketing to blog visitors. You've captured all high-intent keywords, now test medium-intent keywords.
Each step left increases volume but decreases conversion rates and increases cost per customer. This is expected and acceptable. You're not trying to find another channel as efficient as competitor searches. You're trying to find the next most efficient channel after you've maxed the best one.
The working left process: start with competitor searches and brand terms (most aware), expand to solution category searches (solution-aware), add remarketing to website visitors (product-aware), launch LinkedIn ads to target job titles (solution-aware), test content marketing and organic search (problem-aware), only then consider cold outbound (problem-aware). Each step increases volume and increases CAC, but stays within your maximum affordable CAC from the previous chapter.
Don't skip steps. Don't jump from competitor searches directly to cold outbound. Work systematically left through awareness stages, adding the next-hottest traffic source as you max out the current one.
