Engagement is up. But so is frustration.

You’re reporting likes, shares and impressions, but the board wants leads, revenue and evidence of progress.

There’s a growing disconnect between visible marketing activity and meaningful business outcomes. And for many professional services firms, that gap is becoming a credibility issue.

If your marketing reports are padded with vanity metrics, it’s time to rethink what you’re measuring and what story you’re telling in the boardroom.

Metric 1: New client acquisition cost

Boards want to know what they’re getting for the firm’s marketing spend. New client acquisition cost (CAC) gives them a clearer view of return on investment.

Why this matters more than reach

High reach and engagement don’t mean much if they’re not converting into actual client work. CAC helps you understand how much it costs to acquire one new client and whether that cost is sustainable.

When your board sees how your activities translate directly to new business, you move from being viewed as a cost centre to a revenue generator. This is particularly important during budget discussions or when you’re seeking approval for new marketing initiatives.

How to calculate it in professional services

This doesn’t have to be overly complicated. Take your total marketing spend over a period (including outsourced support, tools, advertising, and team costs) and divide it by the number of new clients won during that time.

Example:

• Marketing spend over 6 months = £60,000
• New clients = 12
• CAC = £5,000 per client

Track this quarterly and look for trends. If spend is going up but client numbers aren’t, the board will want to know why and what you’re doing about it.

Making CAC work harder for you

To get even more value from this metric, consider breaking it down by:

• Service line (which offerings have the lowest acquisition costs?)
• Marketing channel (where are your most cost-effective leads coming from?)
• Client size (are you spending appropriately based on potential client value?)

This deeper analysis helps you allocate resources more effectively and gives the board confidence that you’re making data-driven decisions about marketing spend.

Metric 2: Revenue growth from existing clients

Winning new clients is important. But profitable firms know that growth often comes from the clients you already have.

Highlighting cross-sell and upsell potential

Your current client base holds significant untapped revenue. Marketing can support BD teams by identifying opportunities and running campaigns tailored to those segments.

To present this effectively to your board, track:

• Quarter-on-quarter revenue growth from existing clients
• Cross-sell success rates (when clients take on additional services)
• Client retention rates and their correlation with targeted marketing activities

These numbers tell a powerful story about sustainable growth that’s less costly than constant new business acquisition.

Marketing’s role in nurturing existing relationships

• Account-specific content: Create tailored insights that address your clients’ unique challenges
• Sector insights to spark conversation: Develop research or thought leadership that positions your fee earners as experts in clients’ industries
• Targeted email campaigns or LinkedIn activity based on service history: Use data to personalise communications and increase relevance

For example, if you have clients who’ve used your employment law services, you might create a campaign highlighting relevant regulatory changes that could impact their business, establishing a natural path to renewed engagement.

Marketing shouldn’t only feed the top of the funnel, it should help maximise lifetime value from clients who already trust you.

Measuring and reporting success

When presenting to the board, highlight:

• Total revenue from existing clients vs new clients
• Growth in average client value year-on-year
• Success stories where marketing initiatives directly led to expanded client work

This approach demonstrates that marketing isn’t just about acquiring leads—it’s about building relationships that deliver long-term value.

Metric 3: Website to enquiry conversion rate

Traffic is a distraction if you don’t know what it’s doing. A better metric? The percentage of visitors who turn into actual leads.

Not just traffic, how are your CTAs and contact points performing?

Look beyond sessions and page views. Track:

• Contact form submissions
• Phone call clicks
• Email link clicks
• Brochure downloads (if tied to a follow-up path)

Improving your conversion rate is often more effective and more cost-efficient than trying to drive more traffic.

Practical ways to improve conversion

When presenting this metric to the board, include concrete examples of how you’re optimising for conversion:

1. User journey mapping: Show how you’ve identified and removed barriers in the path to enquiry
2. A/B testing: Share results from testing different calls-to-action, form layouts or content approaches
3. Content optimisation: Demonstrate how you’re aligning website content with specific client pain points

For instance, if data shows visitors are abandoning contact forms, you might test a shorter form against the original and report on the improvement in completion rates.

Include before-and-after stats to illustrate the impact of these optimisations on your bottom line.

What to stop reporting (unless you want to lose credibility)

The board doesn’t need:

• Post impressions
• Follower growth
• Likes, reactions, or generic ‘engagement’

Unless you can link these metrics to business outcomes, they’re just background noise.

Focus instead on showing how marketing activities support BD goals and client wins.

How to restructure your board reporting pack

To hold attention (and justify investment), your board reporting needs to be:

• Short: No more than 3–5 slides
• Sharp: Focus on impact and action
• Story-led: Guide them through what’s working, what’s not, and what you recommend

A simple structure to follow:

1. Headline results
   • New leads
   • New clients
   • Marketing-influenced revenue
2. Key success stories
   • What campaigns or content drove real results?
   • Include specific examples with numbers (e.g., “Our regulatory update webinar generated 5 new instructions worth £35,000”)
3. Issues or bottlenecks
   • Where are things stuck or underperforming?
   • Be honest about challenges to build credibility
4. Recommendations
   • Where to invest more (or less), and why
   • Back each recommendation with data from your metrics

It’s not about being flashy. It’s about being clear.

Example reporting template

Create a one-page dashboard with these core metrics:

• Current CAC: £X (up/down X% vs last quarter)
• Existing client revenue growth: X% (target: X%)
• Website conversion rate: X% (up/down X% vs last quarter)

This gives the board an immediate snapshot of marketing performance without overwhelming them with details.

Final thought

If your marketing can’t prove its worth to the board, it won’t get the backing it needs.

Boards don’t care about clicks. They care about clients.

Build your reporting around metrics that reflect your firm’s commercial goals, and marketing will move from ‘nice to have’ to essential to growth.

By focusing on these three metrics, you’ll not only gain more respect in the boardroom, but you’ll also develop a clearer picture of which marketing activities genuinely drive business success. This understanding allows you to continuously refine your strategy and deliver increasing value to the firm.
