How to allocate your marketing budget across channels without guessing. A framework based on managing millions in marketing spend across dozens of companies.

The CMO's Guide to Marketing Budget Allocation

The Annual Budget Guessing Game

Every year, companies go through the same exercise. The CEO asks: "How much should we spend on marketing next year?" The marketing team proposes a number. The CFO cuts it by 30%. Nobody agrees on what the right amount is because nobody has a framework for deciding.

Then comes the harder question: "Where should we spend it?" Google Ads, SEO, content, social, email, events, PR, new website — everyone has an opinion, and the allocation ends up being based on inertia (whatever we spent last year) or politics (whoever argues loudest gets the budget).

This is a guide to breaking that cycle. It is based on managing marketing budgets across dozens of companies in various industries, from $100K to $5M+ in annual marketing spend.

How Much to Spend: The Starting Point

There are industry benchmarks for marketing spend as a percentage of revenue. They are useful as guardrails, not as gospel.

General benchmarks:

  • B2B companies: 6-10% of revenue
  • B2C companies: 8-15% of revenue
  • High-growth companies (targeting 30%+ annual growth): 15-25% of revenue
  • Established companies in stable markets: 5-8% of revenue
These numbers include everything: staff salaries, agency fees, ad spend, tools, content production, events, and overhead.

More important than the percentage is what you are trying to accomplish. A company trying to grow from $5M to $15M in three years needs to invest more aggressively than a company maintaining $50M. The budget should be tied to a growth target, not a percentage.

The formula we use:

1. Set a revenue target for the next 12 months 2. Estimate the number of new customers needed to hit that target 3. Calculate the required number of leads (based on historical close rate) 4. Estimate the cost to generate those leads across your best channels 5. Add fixed costs (team, tools, website) 6. That total is your marketing budget

This approach ties budget directly to revenue outcomes. If the number is too high, you either need to improve efficiency (lower cost per lead, higher close rate) or adjust the revenue target. Either way, the conversation is grounded in math, not opinion.

The Channel Allocation Framework

Once you have a total budget, the allocation across channels should be based on three factors:

Factor 1: Stage of the Buying Journey You Need to Fill

Awareness stage (top of funnel): Content marketing, social media, PR, brand advertising. These channels introduce your company to people who do not know you exist. They are important for long-term pipeline health but do not produce immediate leads.

Consideration stage (middle of funnel): SEO, email nurture, case studies, comparison content, webinars. These channels reach people who are actively researching options. They are the bridge between awareness and conversion.

Decision stage (bottom of funnel): Google Search Ads, retargeting, direct outreach, sales enablement. These channels capture people who are ready to buy. They produce the fastest ROI.

Most companies under-invest in the middle and bottom of the funnel and over-invest in the top. If you need leads now, allocate more to bottom-of-funnel channels. If your pipeline is healthy but you are worried about future growth, invest more in top-of-funnel.

Factor 2: Channel Economics

Every channel has different cost structures and return timelines:

  • Google Search Ads: Immediate results, but you pay for every click. Typical cost per lead: $50-$200 for most industries. ROI is measurable within 30 days.
  • SEO: No per-click cost, but requires 6-12 months of consistent investment before meaningful results. Once it works, cost per lead is very low and compounds over time.
  • Content marketing: Moderate investment, slow build, long-term compounding returns. Most valuable when combined with SEO and email.
  • Email marketing: Lowest cost per lead of any channel ($1-$10 per lead on existing lists). Requires a list to send to.
  • Social media (organic): Low direct cost, but significant time investment. ROI is indirect and hard to measure for most B2B companies.
  • Social media (paid): Comparable to Google Ads in cost, but typically lower intent. Best for retargeting and audience building.
  • Events and conferences: High per-lead cost ($200-$500+), but high-quality relationships. Unpredictable ROI.

Factor 3: What You Already Know Works

If you have historical data on channel performance, use it. This sounds obvious, but many companies allocate budget based on benchmarks and gut feel even when they have data showing exactly which channels produce the best results.

Pull your cost per lead by channel for the last 12 months. Pull your lead-to-customer conversion rate by channel. Calculate cost per customer by channel. Put more money in the channels with the best unit economics. Cut the ones that are not working.

A Practical Allocation for a $500K Annual Budget

Here is how we would allocate a $500K annual marketing budget for a B2B services company doing $8M in revenue and targeting 25% growth:

Paid Search (Google Ads): $120,000 (24%) Immediate lead flow from people searching for your services. Expected output: 80-120 leads per month at $80-$125 per lead.

SEO & Content: $96,000 (19%) Long-term organic growth. Blog content, technical SEO, link building. Expected to produce 50-100+ organic leads per month by month 12.

Website & Conversion Optimization: $48,000 (10%) Redesign or optimization of key pages, landing page development, A/B testing. Improves conversion rates across all traffic sources.

Email Marketing: $24,000 (5%) Platform costs, content creation, automation setup. Expected to produce 15-25% of revenue from existing customers and nurture campaigns.

Paid Social (LinkedIn + Meta Retargeting): $72,000 (14%) LinkedIn for B2B demand generation, Meta for retargeting website visitors. Expected output: 30-50 leads per month.

Marketing Team / Fractional CMO: $120,000 (24%) Marketing leadership and coordination. Either a fractional CMO or part of an internal hire's salary. This is the person who manages everything else on this list.

Tools & Analytics: $20,000 (4%) CRM, email platform, analytics tools, call tracking, reporting software.

Total: $500,000. Expected output: 180-300+ leads per month across all channels, supporting the acquisition of 30-50 new customers per year at an average value of $50K-$80K.

Common Allocation Mistakes

Putting Everything in One Channel

If 80% of your budget is in Google Ads, you are completely dependent on a single platform. Google changes its algorithm, increases CPCs, or suspends your account, and your lead flow drops to near zero overnight. Diversification is insurance.

Spending on Brand Before Demand

Brand marketing matters, but not before you have a functioning demand generation engine. If you cannot generate leads consistently, spending money on brand awareness is premature. Build the pipeline first, then invest in the brand that fills it faster.

No Budget for Measurement

Companies regularly spend $300K-$500K on marketing and $0 on measurement infrastructure. Call tracking, CRM, attribution modeling, and analytics are not optional line items. We cover exactly which numbers to watch in essential marketing metrics every business leader should track. Budget 4-5% of total marketing spend on measurement and reporting tools. You will make it back many times over through better allocation decisions.

Annual Budgets With No Reallocation

Setting a budget in January and sticking to it rigidly through December is a waste. Marketing channels perform differently across seasons and as competitive dynamics shift. Build in quarterly reallocation reviews where you move budget from underperforming channels to outperforming ones.

The Budget Conversation You Should Be Having

The budget discussion should not be "how much can we afford?" It should be "what do we need to invest to hit our growth target, and what return will we get?" If you can demonstrate a 3-5x return on marketing spend with clear attribution, the budget conversation becomes easy — you are not asking for money, you are proposing an investment with a projected return.
