ROI Realities: Part II

In Part I of ROI Realities, we explained why marketing ROI isn't a simple calculation. No opportunity is entirely the result of marketing or of sales, and a single ROI number can't necessarily capture everything marketing contributes to your company.

That leaves an obvious question: if ROI is that complicated, what should you actually do about it?

ROI still matters, and it's definitely worth measuring. The first step in calculating a reliable number is assessing the data your marketing produces. The more complete and credible that data is across every channel, the clearer your picture of what's working becomes.

In Part II of ROI Realities, we're walking through how to track performance across your website, social media, email, and digital advertising, along with a few ways to add context to those numbers. All of it leads up to the point of conversion, when a prospect reaches out to your company. In Part III, we'll talk about what comes after that.

How Do I Track Website Performance?

Your website is where most of your marketing channels converge. For many companies, the goal of their marketing is to drive people to the website, where they reach out, request information, or make a purchase. That makes it one of your most valuable digital channels and the right place to start. Tracking it well typically starts with having Google Analytics 4 (GA4) properly implemented on the site.

GA4 shows how much traffic your site gets, how many visits count as engaged sessions, which pages attract the most visitors, and where your traffic comes from, both geographically and source. Over time, that data tells you how people are finding your company and what they do once they arrive. To learn more about how to set up GA4 for your website, visit Google's GA4 guide.

Your on-site SEO also needs to follow current best practices, and those practices change regularly. We covered on-site SEO and AEO as one of the core components of any website build in Marketing Agency Horror Stories Episode 3. If you want to learn more about what these terms mean and how they affect your business, check out our latest blog on AEO.

Think of your website data as the first link in a chain. It shows where prospects are coming from and how they're reaching you, and when they convert, it's how they enter your sales pipeline.

How Do Privacy Laws Affect My Website Data?

Something that's important to note: privacy has become a much bigger factor in website tracking in 2026. A growing number of U.S. states, led by California, have passed privacy laws similar to Europe's GDPR. As a result, your company may be legally required to ask visitors for consent before tracking their activity on your site, typically through a cookie consent banner and a clear privacy policy.

Skipping that step can open your company to legal action. The cases aren't always clear-cut, but the time and cost of responding to a potential lawsuit is reason enough to address it now. A consent banner and privacy policy make your company a less attractive target for attorneys looking for easy cases. Later this month, we'll explain what these laws mean for your business in more detail in our blog on Cookiebot and consent. We’ve helped many of our clients become compliant, so if you'd like assistance with your site, reach out to us.

With these privacy changes in mind, there's a reporting tradeoff to understand. Once visitors can decline tracking, some of them will, and that share will likely grow over time. GA4 won't capture any data on visitors who opt out, so your website metrics will take a hit. A drop in tracked traffic doesn't necessarily mean your site is underperforming, since you simply won't have visibility into every visitor. Factor that into how you read your reports.

How Do I Track Social Media Performance?

Each social platform reports its own analytics, and the goal is to capture every relevant metric it offers. For most B2B companies, that includes reach, engagement on your posts, follower growth, and clicks through to your website.

On their own, platform metrics have a limit. They show how people interacted with your content on that platform, but not what those people did after they clicked. Adding tracking parameters to the links you share, covered below, connects your social activity to your website data so you can see whether those visits led anywhere.

How Do I Track Email Marketing Performance?

For email, the core metrics are usually opens, clicks (click rate, click-through rate), and unsubscribes. It's also worth watching hard and soft bounces, since both affect your deliverability, though many email platforms automatically filter those addresses out for you. The bigger question is whether you can trust the numbers your platform reports.

We've seen many email platforms, particularly lower-cost ones, report data for our clients that was clearly inflated or unreliable. When we moved those clients to more robust platforms built around deliverability and realistic reporting, the difference in their metrics was notable.

Before you base decisions on your email results, confirm that your platform is giving you credible data. Otherwise, you may be measuring progress that isn't actually happening.

How Do I Track Digital Advertising Performance?

Whether you're advertising on Google, Meta, or another platform, start by pulling complete campaign data from each one. Metrics like impressions, clicks, and cost show how each campaign is performing and how those numbers are trending over time.

The more useful view comes from connecting your advertising data to your website data. Ad platforms show who clicked and what each click cost. Your website analytics show what those visitors did next, including which pages they viewed, how long they stayed, and whether they reached out. Looking at the two together tells you whether your ad spend is bringing in the right visitors and whether that traffic is producing conversions.

How Do I Bring All My Marketing Data Together?

Once you're collecting data from each channel, the next challenge is seeing it in one place. Reviewing every platform separately makes it hard to spot patterns or produce clear reports.

For Google channels, two tools can help. Google Marketing Platform brings Google's analytics and advertising tools, including Google Analytics and Tag Manager, under one platform. Data Studio (formerly Looker Studio) is Google's free reporting tool, which pulls data from sources like GA4, Google Ads, and Search Console into shareable dashboards. Using these tools to bring your Google reporting into one place makes it easier to compare channels side by side and spot changes in performance sooner.

Beyond Google, there are many third-party tools that can aggregate data from more of your channels into a single view. The right fit depends on which platforms you use and how your team needs to report on them. We'll talk more about your technology stack in Part III.

How Else Can I Measure Marketing Performance?

Channel metrics are the foundation, but two other practices can make your data more precise and put it in context.

Add More Layers of Attribution

Trackable phone numbers, QR codes, and vanity URLs (short, memorable web addresses created for a specific campaign) show more clearly how people are engaging with your marketing and reaching out to your company. They work in both digital and traditional advertising, from online ads to print and trade show materials.

UTM parameters do the same job for digital links. These are short tags added to the end of a URL that identify the source, medium, and campaign that brought a visitor to your site. Adding UTMs to the links in your paid ads, organic social posts, and emails lets GA4 accurately attribute those website visits to a specific channel and campaign, so you can see which efforts are driving traffic and conversions.

Benchmark Against Your Competitors

Your own data shows how your marketing is performing over time, but it can't tell you how that performance compares to others in your industry. Gathering comparable data on competitors' website traffic and social media engagement helps you judge whether your marketing is healthy. Since ROI isn't a straightforward calculation, the goal is to bring together as much relevant data as you can. With that data in hand, you can measure progress two ways: against your own past performance and against your competitors.

Competitor traffic data requires a third-party platform, and even then, the numbers are estimates rather than exact figures. That’s where experience can help. Someone who works with this data regularly can tell which estimates are reliable enough to act on, spot the trends worth paying attention to, and put the numbers in context alongside your own results. Gathering the data is one thing, but interpreting it correctly is what makes your benchmarks useful.

Conversions: Where It All Leads

Every metric covered above points toward one outcome: conversions. That includes form submissions, phone calls generated by your marketing, and emails to your sales team or staff. Conversions are the clearest sign that your marketing is generating real business opportunities.

The rest of your data shows whether the strategies and tasks behind your marketing are working well enough to drive more of those conversions. Taken together, that's the information you need to start determining ROI.   

Tracking conversions only gets you halfway there. Once a prospect converts, you still need to know what that lead turns into. In Part III, we'll cover how to track conversions all the way through to revenue, along with the technology and team alignment it takes.

Setting up tracking and attribution so everything works together is critical to calculating ROI, but it isn’t simple. This is work we do regularly for our clients, so if you have questions, we’d be happy to help. Feel free to reach out to us.
