When every ad platform claims full credit for conversions, how do you judge your overall ROI?
That 400% return on ad spend (ROAS) you see in Google Ads or Meta Ads looks nice—except when you look at your actual sales and profit margins and the results don’t match up.
This is why it’s so important to distinguish between ROAS and true PPC ROI. Here’s everything you need to know about getting a unified view of ad spend and returns so you can make better decisions when allocating budgets.
PPC ROI vs. PPC ROAS: Understanding the Difference
ROAS and ROI are both ways to measure PPC performance—but they tell different stories.
ROAS measures revenue efficiency. It answers: “How much revenue did I generate for every dollar I spent on ads?”
Formula:
ROAS = (Revenue ÷ Ad Spend) × 100%
If you spent $5,000 and made $20,000, your ROAS is 400%. That looks great—but it doesn’t mean you made a profit.
PPC ROI (Return on Investment) tells you about true profitability. It factors in all your costs—like software, agency fees, and internal labor—to answer: “How much profit did I earn for every dollar I invested?”
Formula:
ROI = [(Revenue – Total Costs) ÷ Total Costs] × 100%
If that same $20,000 in revenue came from $5,000 in ad spend plus $7,000 in other costs, your ROI is only 17%.
Your ROAS is most useful for optimizing ad performance within specific platforms like AdWords or Meta. It tells you how efficiently you’re deploying ad dollars in a given platform.
PPC ROI gives you a more holistic picture of your PPC program as a whole. It’s what you use to zoom out and evaluate the real-world financial impact of all ad campaigns and initiatives. This insight is how you decide how much budget to allocate to PPC across the board (and how much money to spend per platform).
How to Calculate PPC ROI in 4 Simple Steps
The process to calculate PPC ROI is more involved than simply tracking ROAS within a platform. But with the right steps and tools, you can get that visibility easily. These 4 simple steps will give you the full picture of PPC ROI for your business.
Step 1: Determine Your Total PPC Costs
Before you can calculate ROI, you need to know what you actually spent on your campaigns. And that goes beyond just the media budget.
Start with direct costs, like:
- Ad spend across platforms (Google Ads, Meta, Bing, LinkedIn, etc.)
- Cost-per-click (CPC) campaigns and programmatic display buys
Then add your indirect costs. This is where some costs slip through the cracks. Pull in all costs associated with running PPC campaigns. That might include:
- Agency retainers or freelancer fees
- Design and copywriting costs for ad creatives
- Landing page development and A/B testing tools
- Analytics or bid management software
- List-building tools and credits associated with data enrichment to build targeting lists
As an example, let’s say you spent $10,000 on Google and Facebook ads. But you also paid $2,000 to a freelance designer, $1,000 for landing page dev work, and $500/month for analytics software. That’s $13,500 total—not $10,000.
If you aren’t using the fully-baked costs of ad programs, you risk overestimating your ROI. And when you overestimate your ROI, you may make compounding mistakes in allocating budget to PPC campaigns.
Step 2: Track Conversions and Revenue
Once you know what you’re spending, the next step is understanding what you’re getting back.
That starts with proper conversion tracking. Without it, your ROI numbers are incomplete—or worse, misleading. Every PPC platform tracks conversions differently, so it’s crucial to set up a consistent system that captures the full customer journey.
Define what counts as a conversion for your business:
- For e-commerce, it might be an online purchase.
- For B2B, it could be a demo request, a lead form submission, or even a qualified phone call.
- For SaaS, it might be a free trial or account signup.
Once you’ve defined the conversion, assign a dollar value to it:
- If it’s a direct sale, use the revenue amount.
- If it’s a lead, estimate based on your average close rate and deal size. For example, if 1 in 5 leads becomes a $5,000 deal, that lead is worth $1,000.
This all gets a bit more complicated when you have long sales cycles. A click today could contribute to a deal six months from now—well outside the attribution window of most ad platforms. That’s why connecting your PPC data to your CRM is essential.
Tools like The Attribution Platform bridge this gap by pulling conversion data from both online and offline sources—so whether a deal closes via web form or phone call, you see the full revenue impact tied back to each touchpoint along the way.
Step 3: Apply the ROI Formula
With your total costs and revenue in hand, it’s time to do the math.
As a reminder, the formula for PPC ROI is:
ROI = (Revenue – Total Costs) ÷ Total Costs × 100%
Let’s walk through a realistic example. Say you ran a quarterly PPC campaign with the following:
- Ad spend: $20,000
- Indirect costs (design, tools, agency fees): $5,000
- Total costs: $25,000
- Revenue generated from the campaign: $75,000
Here’s how the formula would work out:
ROI = [($75,000 – $25,000) ÷ $25,000] × 100% = 200%
What that means is that for every $1 you invested, you earned $2 in profit. That’s a healthy return—especially if you’re scaling spend responsibly.
You could track all of this over time in a spreadsheet. But visualizing the data can help you uncover more insights more easily.
The Attribution Platform makes it easy to visualize your omnichannel marketing campaigns, whether that’s with bar charts comparing ROI across channels, trend lines for ROI over time, or side-by-side comparisons between ROI and ROAS.
Step 4: Segment and Analyze
To get meaningful insights into ROI, you need to break the data down into smaller parts. That means analyzing results by:
- Campaign or ad group: Spot high-ROI campaigns worth scaling and low-performers that need to be paused or reworked.
- Keyword or audience: Compare branded vs. non-branded keywords, or new vs. remarketing audiences.
- Device or location: See if mobile traffic converts as efficiently as desktop, or if certain regions deliver better returns.
For example, you might discover that one ad group targeting mid-funnel buyers has a 300% ROI, while another cold-audience campaign is losing money. Instead of cutting budget across the board, you can reallocate toward what’s working.
These insights are often buried in siloed ad platforms. The Attribution Platform pulls it all into one dashboard, so you can slice ROI data any way you need—by channel, cohort, conversion type, or segment—and optimize with confidence.
The Danger of Siloed Data: Why Platform-Specific Metrics Mislead
If you’re measuring PPC performance using only the metrics inside Google Ads or Facebook Ads Manager, you’re only seeing part of the story—and often, it’s the part those platforms want you to see.
Each ad platform is designed to show itself in the best light. That means Google might take full credit for a conversion even if Facebook played a role earlier in the journey. And Facebook will do the same. When you rely on these siloed reports, it’s common to see multiple platforms claiming the same sale, leading to double-counted conversions and inflated ROI.
You also run into other common challenges, including:
- Last-click attribution bias: Most platforms default to giving 100% credit to the final touchpoint, which undervalues early-stage interactions that started the journey.
- Inconsistent attribution windows: One platform might attribute a conversion for up to 30 days, another for only 7—leading to misaligned results.
- Fragmented customer journeys: Real users don’t convert in one click. They engage across platforms and devices, which siloed data fails to connect.
- No shared source of truth: When each platform only tracks what happens within its own walls, there’s no way to know which campaigns are actually responsible for driving revenue.
This fragmented view leads to poor decisions—cutting campaigns that are working, overspending on those that aren’t, and missing the full picture of what’s driving conversions.
Make Your PPC ROI Measurement More Accurate with These Strategies
Measuring PPC ROI isn’t just about plugging numbers into a formula—it’s about tracking the right data, in the right way.
These strategies will help you tighten up your measurement, eliminate blind spots, and get closer to the true value of your campaigns.
Multi-touch Attribution
Most PPC platforms default to first-touch or last touch attribution—giving 100% of the credit for a conversion to the final ad click before a sale. That might work for simple, one-click purchases (and even then it’s limited). But it completely breaks down in more complex journeys—especially in B2B, where buyers interact with multiple touchpoints over weeks or months.
Multi-touch attribution (MTA), or multi-channel attribution, offers a smarter way. Instead of crediting just one click, it distributes value across the entire customer journey. There are several models, each offering a different perspective on performance:
- Linear attribution splits credit evenly across all touchpoints. Simple and fair, but it assumes every interaction has the same impact—rarely true.
- Time-decay attribution gives more credit to recent interactions. It’s better for long sales cycles, but may undervalue the early ads that planted the seed.
- Position-based attribution (often called U-shaped) typically gives 40% to the first and last touch, and divides the remaining 20% across the middle. This is great for capturing both introduction and conversion moments.
- Data-driven attribution uses real performance data to assign credit based on what actually influenced the sale. This is what platforms like Google Analytics 4 use by default—if there’s enough data.
These kinds of models are important because if you’re only using last-click attribution, you’ll miss the impact of upper-funnel PPC campaigns—like display ads, top-of-funnel search terms, or awareness-focused LinkedIn ads.
These touchpoints often don’t drive immediate conversions, but they play a critical role in nudging users toward the final decision. Multi-touch attribution brings that value to light, helping you invest more confidently in campaigns that spark interest and build pipeline.
Bridging Online and Offline Conversion
Not every PPC conversion happens on a website. For many businesses—especially in B2B, retail, or service industries—the final sale might come through a phone call, an in-person visit, or even a signed contract weeks after the initial click. If you’re only measuring what happens online, you’re missing a big part of the ROI picture.
To connect the dots between online ads and offline results, you need a few smart tracking strategies:
- Call tracking solutions assign unique phone numbers to your campaigns, channels, or even keywords. When someone calls, you’ll know exactly which ad drove the action—and whether it converted.
- Promo codes and custom URLs make it easy to tie offline purchases back to specific campaigns. For example, a Google Ad offering “Use code SPRING20 in-store” tells you exactly where the customer came from.
- Campaign-specific landing pages give you control over the user journey and make tracking much easier. If a lead lands on a dedicated PPC landing page, then later signs a contract, you know where they started.
- CRM integrations connect form submissions, phone calls, or offline interactions to your PPC clicks. When a lead turns into a closed deal weeks or months later, the original campaign still gets credit.
Incorporating offline conversions into your reporting transforms your ROI view from fragmented to full-funnel.
Cohort Analysis
Instead of measuring ROI in a fixed window, cohort analysis tracks how revenue unfolds over time for specific groups of customers.
A cohort is simply a group of users who share a common trait—like converting from the same PPC campaign or being acquired in the same month. By grouping conversions this way, you can track how ROI grows month over month for each cohort.
To set up cohort tracking, start by organizing your data by:
- Campaign launch date (e.g., “Leads from our January Google campaign”)
- Customer acquisition date (e.g., “Customers acquired in Q1 via Facebook Ads”)
From there, monitor how each group’s revenue builds over time. This reveals critical insights, like:
- Time to profitability: Do your campaigns recoup costs within 30 days—or does ROI emerge months later?
- Short-term vs. long-term ROI: Are some campaigns flash-in-the-pan performers, while others generate lasting value?
- Seasonality: Do Q4 campaigns consistently outperform Q1? Are certain keywords stronger during specific months?
As an example, imagine you launched three campaigns in January, February, and March. Using cohort analysis, you see that:
- January’s campaign reached break-even in 30 days and generated 200% ROI by Day 90.
- February’s campaign had slower traction—ROI hit 100% only after 6 months.
- March’s campaign looked strong upfront, but revenue plateaued early.
With this visibility, you can confidently double down on campaigns with long-term payoff, reduce budget waste on short-lived spikes, and adjust strategy based on how long results typically take to materialize.
Benchmarking PPC ROI: What’s Considered “Good”?
Once you’ve built a system for accurately measuring PPC ROI, the next question is inevitable: What’s a good ROI? The answer depends on your industry, business model, and how your campaigns are structured—but some general benchmarks can help set expectations.
Here’s a rough breakdown of what different sectors might aim for:
- Ecommerce (200-400% ROI): Lower margins and higher volume mean e-commerce brands often rely on scale. Break-even in the first sale is common, with profit coming through repeat purchases and LTV.
- B2B SaaS (150-300%): With longer sales cycles and higher customer LTV, B2B SaaS companies may accept slower ROI ramp-up—as long as the long-term return is strong.
- Lead generation (200-500% ROI): Because lead-gen campaigns don’t track direct revenue, ROI is often modeled based on close rates and average deal size. High ROI is possible when acquisition costs are kept low and conversion rates are high.
- Service businesses (300–600% ROI): Services often carry higher margins, and local or niche targeting can keep costs down. These factors typically lead to stronger ROI—especially when campaigns drive phone calls or in-person visits.
While these numbers are helpful, they’re only a starting point. Many factors influence what your ROI should look like, including:
- Your average order value (high-ticket products may allow for lower volume but higher ROI)
- Your profit margins (lower-margin businesses need higher ROI just to stay profitable)
- The length of your sales cycle (slower cycles may delay ROI, even if the return is substantial)
- Your competitive landscape (more competition drives up CPCs, which can suppress ROI)
Rather than chasing external benchmarks alone, your best move is to establish internal benchmarks based on your own performance data. Look at past campaigns by channel, time frame, or offer type. Use cohort analysis to see when profitability kicks in. Then, set realistic ROI goals that align with your customer acquisition strategy and broader business objectives.
Ultimately, a “good” PPC ROI is one that supports your growth sustainably—whether that means quick wins or long-term payback.
Best Practices for Optimizing PPC ROI
Any PPC effort is a game of testing and optimizing. As you run your campaigns, the following are a few ways to improve ROI as you gather data.
Budget Allocation and Bid Management
Optimizing PPC ROI starts with continuously shifting budget away from underperformers and into the campaigns, keywords, and audiences that are delivering the strongest ROI.
With the right attribution in place, you can identify which campaigns are driving real profit, which keywords convert at high values, and which audiences show strong long-term returns (all in terms of profitability, not just on-platform conversions).
Once you know what’s working, reallocate your budget accordingly. That might mean pausing low-ROI campaigns, raising bids on high-performing terms, or testing new offers for promising segments.
Beyond allocation, your bidding strategy has a major impact on ROI. Rather than optimizing for basic conversions, consider bidding strategies that prioritize value:
- Target ROAS (tROAS) bidding automatically adjusts bids to hit your desired return, factoring in historical conversion value.
- Maximize conversion value bidding focuses on generating the most revenue, not just the most leads.
You can take these strategies a step further with dayparting. This technique allows you to focus your spend during hours or days when performance is strongest. For example, if your data shows that weekdays from 10 a.m. to 2 p.m. drive the highest ROI, you can reduce bids—or pause ads entirely—outside those windows.
Audience Refinement
PPC ROI is about profitability, not reach. And often, shrinking your reach by refining your audience targeting can lead to improved ROI.
Start by narrowing your targeting to exclude unqualified traffic:
- Use demographics, job titles, or firmographic filters to zero in on your ideal buyer.
- Layer in behavioral signals, like past website visits or engagement with specific content, to qualify intent.
Next, implement retargeting campaigns to stay in front of users who already know your brand. These audiences typically convert at much higher rates, making them a smart bet for efficient spend. You can retarget users who:
- Visited key landing pages
- Watched a product video
- Started—but didn’t complete—a form
To expand your reach without starting from scratch, build lookalike audiences based on your highest-value customers. Platforms like Meta and Google can find users who share characteristics with your best converters—helping you scale without sacrificing quality.
The key is precision. Audience refinement is about putting your budget in front of the people most likely to drive long-term value. With The Attribution Platform, you can analyze ROI by audience segment, so you can see exactly which groups are worth targeting—and which to leave behind.
Cross-Channel Insights
When you analyze channels in isolation, you miss the bigger picture. But when you look across platforms, patterns emerge that can inform smarter strategy and stronger ROI.
For example, if a Google Ads campaign is driving high-value traffic, but those same users are converting later via Facebook retargeting, that’s not a failure of paid search—it’s proof that the two are working together. The Attribution Platform captures these interactions so you can connect the dots and assign value across the full journey.
You can also apply learnings from one channel to another:
- A high-converting keyword on Google may hint at messaging that can improve performance in Meta ads.
- Top-performing creatives in a paid campaign might inform new content for your SEO or email funnel.
- Landing pages that convert from LinkedIn ads could be tested for organic blog CTAs.
A major blind spot for many marketers is the disconnect between organic and paid search. Often, branded paid search is just capturing demand already generated by organic efforts—or vice versa. By looking at ROI holistically, you can reduce cannibalization and double down on what’s actually driving net new results.
The ultimate goal is to balance your spend across channels based on unified ROI data—not platform reports alone.
