How to Get the Best ROI From Your Marketing Agency

Getting the best ROI from a marketing agency requires more than hiring the right partner. Learn how CRM access, lead quality feedback, collaboration, and clean data can help your agency make smarter decisions and drive better results.

Key takeaways

• Give your agency appropriate CRM access so it can connect leads to actual business outcomes.
• Define what a qualified lead means (and what makes a lead unqualified) before campaigns launch.
• Create fast feedback loops between sales, marketing, and your agency to avoid optimizing toward poor-quality leads.
• Set up platform access, data expectations, and ownership before kickoff to avoid unnecessary delays.
• Keep CRM data accurate and use automation to help your agency optimize toward the leads and customers that matter most.

Hiring a reputable agency is the best way to grow and scale your marketing efforts.

But there are extra steps you can take to get the biggest return on investment (ROI) from your marketing agency, too.

Your agency needs enough visibility into your business to understand which marketing campaigns are actually driving value — not just clicks, traffic, or lead volume.

That starts with access to the data that lives beyond your ad platforms and analytics tools, particularly your CRM.

We spoke with HawkSEM Director of Agency Operations Ericka Aghili and Team Lead Melissa Torre about what separates agency partnerships that consistently deliver ROI from ones that stall out early.

1. Give your marketing agency CRM access

Advertising and analytics platforms can provide an agency with valuable conversion data, whether that’s a form fill, a phone call, or a chat submission.

What those platforms can’t tell an agency is whether that conversion turned into a qualified lead or a customer.

Closing that gap can help your agency make better-informed decisions and get more value from your marketing investment. In most cases, that starts with CRM access.

CRM data connects marketing efforts with business outcomes

“A report might show that paid search generated 50 leads and organic search generated another 50, but that comparison alone doesn’t reveal whether those leads were equally valuable,” says Aghili.

CRM visibility lets an agency look past lead volume and cost per lead to what actually happened next.

Two channels that look identical on a conversions dashboard can be performing very differently once that data is factored in. Attribution can help connect those outcomes to the customer journey, although no attribution model provides a perfect picture.

CRM access improves PPC optimization

CRM access also changes how paid campaigns get managed.

Rather than optimizing toward the cheapest or highest volume of form fills, campaigns can optimize toward the actions most associated with qualified opportunities.

“That information can help us optimize campaigns toward leads that are more likely to become qualified opportunities rather than simply generating the highest volume of conversions at the lowest cost,” says Torre.

In practice, that often means feeding qualified-lead or offline conversion data back to the ad platform so its bidding algorithms have a better signal to work with.

This can help platforms such as Google Ads optimize toward more meaningful conversion rates, cost per acquisition (CPA), and customer acquisition cost (CAC) rather than simply maximizing conversion volume.

CRM data improves SEO strategies

This isn’t just a PPC consideration.

“For SEO, CRM data can help us understand whether the traffic and leads coming from organic landing pages and content are reaching the right audience and contributing to your business goals,” Aghili says.

For search engine optimization (SEO) and content marketing, that might mean determining whether organic traffic from a blog post or landing page is ultimately contributing to qualified opportunities or revenue

Without that data, organic performance can get judged purely on traffic and lead volume, which can make a page look successful even when it’s attracting the wrong target audience.

What CRM access does your agency actually need?

In most cases, your agency doesn’t need unrestricted access to everything in your CRM. Read-only access to the information that helps connect marketing activity to business outcomes is usually enough.

That may include:

• Read-only access when possible
• Lifecycle stage
• Lead source
• Lead status
• Deal stage
• Close date
• Lost reason
• An internal contact for questions

Your CRM also doesn’t need to be perfectly configured before you hire an agency. What matters is knowing what exists, how reliable it is, and where the gaps are. Identifying those gaps early gives your agency a chance to help determine what information will be most useful.

Not every business has a CRM, and not having one doesn’t mean agency-led marketing can’t succeed. But when that data is available, giving your agency access to it means decisions get made with a much clearer picture of what’s actually driving value for the business.

2. Define what a quality lead looks like to your business

“One of the first things your agency needs to understand is what a good lead actually means for your business,” Aghili says. “That sounds simple, but different teams can have very different definitions.”

For one company, a good lead might be a marketing-qualified lead generated through PPC or paid social. For another, it might be a real conversation with sales. A third might only count qualified opportunities or closed revenue.

Each definition points strategy in a different direction, from budget allocation and audience targeting to retargeting and campaign optimization.

Define an unqualified lead, too

It matters just as much to define the opposite. Common signs of an unqualified lead include:

• Wrong industry
• Company too small, or too large, for the service
• Outside the service area
• A job seeker rather than a prospect
• Spam or bot activity

Sharing those patterns lets an agency look for trends across campaigns, keywords, audiences, landing pages, and content, and adjust targeting accordingly.

What matters most, according to Torre, is that the client, sales team, and marketing team are all working from the same definitions.

“Otherwise, marketing can believe it’s generating strong results while sales is having a very different experience with those leads,” she says.

3. Create fast feedback loops with your agency

“If we don’t learn that a group of leads was unqualified until two months later, we’ve potentially spent another two months investing in the same audience, keywords, content, or campaign strategy,” says Torre.

“The faster we know whether we’re attracting the right leads, the faster we can adjust our strategy.”

That two-month gap is often where marketing spend gets wasted without anyone noticing right away.

There are two ways to close that gap:

1. With CRM access, an agency can investigate lead quality directly instead of repeatedly asking the client to pull a report.
2. Without CRM access, the next-best option is a regular, structured process for sharing lead quality feedback instead of an occasional one.

These feedback loops can also help your agency establish a benchmark for lead quality and track performance metrics over time.

Bring sales into the feedback loop

Sales teams often know within days, sometimes hours, whether a lead is worth pursuing.

Establishing a simple way to get that information back to both the internal marketing team and the agency turns sales insight into another data point marketing can act on.

“Getting that information back to the marketing team gives us another data point we can use to make better decisions,” says Aghili.

4. Get access and setup out of the way before kickoff

One of the easiest ways to lose momentum at the beginning of an agency relationship is to spend the first few weeks figuring out who owns different platforms, who can grant access, or what data is available.

Before kickoff, it helps to establish:

• What CRM do you use?
• Who owns or administers it?
• What data is tracked?
• How consistently is it updated?
• Can your agency have read-only access?
• Who owns your Google Ads, Google Analytics, and other platforms?
• Are there security or compliance requirements to plan around?
• Who should the agency contact when access or data issues come up?

Answering those questions early isn’t about handing over unnecessary permissions. It’s an efficiency issue: the sooner an agency knows what it’s working with, the sooner it can focus on strategy instead of logistics.

5. Keep your CRM data clean and up to date

Giving an agency CRM access doesn’t help nearly as much if lead statuses aren’t updated, deal stages are inconsistent, lead sources aren’t captured correctly, or closed and lost reasons are missing.

As Aghili puts it, “Automation is only as useful as the data feeding it.”

The same is true of ordinary reporting and decision-making: incomplete or inconsistent CRM data leads to incomplete or inconsistent strategy, no matter how much access an agency has.

6. Use automation and AI to turn better data into better performance

When CRM data is accurate, it can feed a fairly simple loop:

• Marketing generates a lead
• The CRM tracks what happens to it
• Qualified-lead data goes back to the advertising platform
• Bidding systems get a stronger signal about which conversions actually matter

For example, accurate data can help paid campaigns optimize toward return on ad spend (ROAS) rather than simply maximizing conversion volume.

It can also help marketers understand customer lifetime value (CLV) and determine whether acquisition costs make sense relative to the revenue a customer generates.

An API connection can automate part of that process by sending lead status information back to the platform automatically.

“Automation doesn’t replace human review,” Torre says. “It also depends on the information in the CRM being accurate and consistently updated. If the underlying data isn’t reliable, sending it back to the platform won’t give us the quality signals we need.”

In other words, automation can act on good data quickly, but it can’t turn bad data into good data on its own.

7. Help your agency collaborate across marketing channels

Most businesses run marketing through more than one channel or vendor. Social media, email marketing, SEO, PPC, content marketing, and paid ads may all contribute to the same customer journey.

Without a shared view, a PPC agency reports its conversions, an SEO team reports organic traffic, a social vendor reports engagement rates, and sales sees a different picture altogether.

“The CRM is often where those leads come together, giving us a clearer picture of the quality of leads each channel is contributing,” Aghili says.

That shared source of truth lets an agency compare marketing channels and understand how those efforts work together instead of competing for credit.

The same principle applies beyond data: channels and vendors that coordinate, rather than operate in silos, tend to produce better results for the business as a whole.

8. Treat your agency like a strategic partner

A lot of what makes an agency relationship work well has less to do with platforms and more to do with communication.

That includes:

• Share business goals, not just marketing KPIs
• Tell the agency when priorities change
• Give context behind performance changes
• Share sales and customer insights
• Be candid when lead quality declines
• Give timely feedback
• Allow room for A/B testing and iteration

The more an agency understands the business behind the marketing metrics, the better equipped it is to make strategic decisions rather than reactive ones.

That might mean discussing a new product launch, changes to your target audience, a shift in your marketing budget, or a change in your broader strategic planning — including how those decisions affect brand awareness, lead generation, and revenue.

9. How to measure ROI from your marketing agency

The goal isn’t to track more performance metrics. It’s to measure the key performance indicators (KPIs) that show whether marketing is creating business value.

Clicks, click-through rates, website traffic, and raw lead volume are easy to report, but they rarely tell the whole story on their own. Depending on the engagement, more meaningful metrics can include:

• Conversion rates
• Cost per lead
• Cost per acquisition (CPA/CAC)
• Qualified leads
• Opportunities and pipeline
• Return on ad spend (ROAS)
• Customer lifetime value (CLV)
• Revenue and gross profit
• Organic traffic and SEO-driven leads
• Customer retention

These metrics help put your marketing investment into context. If your marketing costs are rising but customer lifetime value and gross profit are increasing faster, the investment may still be producing a strong return.

On the other hand, low-cost leads aren’t necessarily valuable if they rarely become customers.

Your agency can also use these metrics to evaluate cost per acquisition, lead quality, and the relationship between acquisition costs and CLV over time.

The bottom line

Getting more from your marketing agency takes a collaborative approach.

The more clearly your agency can see what happens after those leads enter your sales process, the better equipped it is to identify what’s actually driving value and adjust strategy accordingly.

If you’re preparing for a kickoff call or evaluating a new agency partner, bring these conversations to the table early.
