Want to know if your local display ads are making money? Start here. Measuring ROI (Return on Investment) tells you if your ad spend is paying off. Here’s what you need to know:

  • ROI Formula:
    ROI = [(Revenue - Total Ad Costs) / Total Ad Costs] × 100
    Example: Spend $200, earn $600 → ROI = 200%.
  • ROI vs. ROAS:
    ROI measures profitability (net profit), while ROAS (Return on Ad Spend) shows efficiency (gross revenue). Use ROI for big-picture decisions and ROAS for tweaking campaigns.
  • Conversion Tracking Tools:
    Tools like geo-fencing, GPS, and beacons help track in-store visits. Google Ads and Facebook offer features like phone call tracking and direction requests to connect online ads to offline sales.
  • Key Metrics to Watch:
    • Click-Through Rates (CTR): Average for Google Display is 0.46%; aim higher with better targeting.
    • Local Action Costs: Average cost per click for display ads is $0.63.
  • Budget Optimization:
    Focus on high-performing campaigns and channels. Use tools like Google Analytics or AI-powered platforms like Humble Help for real-time ROI tracking.

Bottom Line: Track ROI to know what works, cut what doesn’t, and make smarter ad decisions. Ready to dive deeper? Let’s explore how to make your local ads profitable.

ROI Basics for Local Display Ads

Understanding the basics of ROI is essential for small businesses running local display ad campaigns. Advertisers often report ROI ratios ranging from 2:1 to 8:1 on their Google Ads investments [2]. Let’s break down how to calculate ROI and see how it differs from ROAS.

How to Calculate ROI

Here’s the formula for ROI:

ROI = [(Revenue - Total Ad Costs) / Total Ad Costs] × 100

To make this clearer, let’s look at an example. Imagine a fitness brand spends $200 on Facebook Ads to promote a one-month free trial. This campaign results in 100 signups, and 20 of those users become paying customers, each contributing $30 per month.

ROI = [((20 × $30) - $200) / $200] × 100 = 200%

To calculate ROI effectively, consider these key factors:

  • Total ad spend, including creation and management costs
  • Revenue generated from conversions
  • Customer acquisition costs
  • Lifetime value of each customer

Now, let’s dive into how ROI compares to ROAS and why both metrics matter.

ROI vs. ROAS: What’s the Difference?

While ROI and ROAS are both critical metrics, they serve different purposes in evaluating ad performance. ROI focuses on overall profitability, while ROAS measures the efficiency of specific ad spend.

Metric Purpose What It Measures Best Used For
ROI Overall profitability Net profit after all costs Long-term business decisions
ROAS Ad campaign efficiency Gross revenue generated from ad spend Short-term campaign adjustments

As Waseem Bashir, Founder & CEO of Apexure, explains:

"ROAS helps us pinpoint which advertising channels are most effective, while ROI across different demographics or locations informs our marketing focus. Additionally, integrating these metrics with Customer Lifetime Value (CLV) allows us to identify which sources deliver the highest value, guiding resource allocation for maximum impact." [4]

Key Insights for Small Businesses

  • A strong ROI is typically considered 5:1 (500%) [2].
  • An ROI below 2:1 indicates the business may be losing money [3].
  • Personalization can significantly boost ROI - 80% of consumers are more likely to respond positively to personalized experiences [3].

For small businesses, ROI offers a comprehensive view of how effective your advertising efforts are in driving growth and profitability. While ROAS helps fine-tune individual campaigns, ROI ensures your overall marketing strategy aligns with your business goals.

Conversion Tracking Methods

Getting conversion tracking right is crucial for understanding how well your local display ads perform. With potential customers needing anywhere from 1 to 50 interactions before making a purchase [5], having a reliable tracking system in place is key to measuring your return on investment (ROI).

Location-Based Tracking Tools

Modern tools like geo-fencing, GPS, and beacons give businesses powerful ways to measure campaign performance by tracking customer movements and interactions.

Tracking Method Best Used For Key Benefits
Geo-fencing Tracking store visits Activates ads when customers enter specific areas
GPS-Based Real-time location targeting Tracks precise customer movement patterns
Beacon-Based In-store engagement Monitors close-range interactions with customers
Local Actions Google Maps engagement Tracks actions like directions or calls to your business

Google Ads provides several local action conversion options to measure customer engagement effectively:

  • Directions: Tracks when users click to navigate to your business.
  • Website visits: Monitors clicks that lead to your business website.
  • Clicks to call: Records phone call attempts made through your ads.
  • Other engagements: Captures actions like "Save" or "Share Location."

While these tools are excellent for tracking online interactions, connecting them to offline sales is just as important.

Offline Sales Tracking

Surprisingly, only 44% of small businesses track offline sales, even though linking online engagement to in-store purchases can give you a major advantage [7].

To bridge this gap, you can implement online-to-offline tracking by using unique identifiers, automating data collection tools like CallRail, and assigning specific values to different types of conversions.

Conversion Type Tracking Method Value Assignment
Store Visits Geo-tracking Assign based on average purchase value
Phone Calls Call tracking Value determined by lead close rate
Direction Requests Maps engagement Estimate based on expected visit value

"Conversion tracking empowers you to maximize profits and save money in Google Ads" [6].

Main ROI Metrics to Track

To make informed budget decisions for your local display ads, it's crucial to focus on key metrics. A notable 63% of marketers view ROI as their leading performance indicator [9]. Among the most important metrics to evaluate are click-through rates (CTR) and local action costs.

Local Click-Through Rates

Click-through rates (CTR) measure how effectively your local display ads connect with your target audience. While the average CTR for display ads is 0.1% [10], local businesses can often surpass this by fine-tuning their campaigns.

Ad Platform Average CTR Target Value
Google Display Network 0.46% Industry standard
Facebook Newsfeed 1.11% Good performance
Instagram Feed 0.22% Platform average
Dynamic Feed Ads 2.30% Top performance

To improve CTR, try strategies like behavioral prospecting, contextual targeting, and dynamic feed ads. In fact, dynamic feed ads have shown to boost CTR by as much as 117.5% in certain industries [10].

Local Action Costs

CTR is important, but understanding local action costs is equally essential for optimizing your ad spend. Here are some benchmarks to keep in mind:

Action Type Average Cost Target Value
Cost Per Click (Search) $2.69 Across industries
Cost Per Click (Display) $0.63 Across industries
Cost Per Action (Search) $48.96 Across industries
Cost Per Action (Display) $75.51 Across industries

Key local actions to track include:

  • Direction requests
  • Phone call initiations
  • Coupon downloads
  • Store visit conversions

It's worth noting that display ads typically have a conversion rate of 0.77%, whereas search ads perform significantly better with a 3.75% conversion rate [11]. By closely monitoring these metrics, you can adjust your budget and expectations accordingly, ensuring your strategy is aligned to maximize ROI.

ROI-Based Campaign Updates

Let’s dive into practical ways to tweak campaigns using ROI metrics to maximize returns.

Local Budget Distribution

One effective strategy is to reallocate your local ad budget. Focus on areas where returns are strong and cut back on spending in regions or channels that underperform. For instance, a local dog food company invested $100 in newsletter ads and saw a return of $340, achieving a 240% ROI [16]. This success led them to shift more resources toward these high-performing channels. After reallocating, fine-tune ad elements to push ROI even further.

Ad Design Updates

ROI insights can also guide updates to underperforming ad designs. Here are a few ways to approach this:

  • Visual Optimization
    Improve the look of your ads by using high-contrast images, incorporating elements relevant to specific locations, and ensuring layouts are mobile-friendly [15].
  • Call-to-Action (CTA) Enhancement
    Strengthen CTAs with clear, compelling text overlays.

    "It's best to incorporate text overlays with strong CTAs. Because display ads are notoriously low converting, try to mitigate this by being very clear within the CTA" [15].

  • Landing Page Alignment
    Ensure your landing pages match the messaging and visuals in your ads. This creates a smoother user experience and boosts conversions.

    "Make sure the landing page experience post-click is CRO optimized. Visually, you want the display ad and the landing page to have a lot of synergy to minimize confusion post-click" [15].

If you’re looking for tools to track and improve ROI, platforms like Humble Help can be game-changers. They use AI-powered analytics to pinpoint weak spots in your ads and suggest design tweaks tailored to your local market data.

FAQs

How can I measure the offline impact of my local display ads effectively?

To gauge how your local display ads are driving offline activity, there are several effective approaches you can take. One option is to use custom URLs or unique tracking codes. These let you pinpoint traffic that comes directly from your ads. Another method is to monitor shifts in organic search traffic or direct visits to your site during the campaign. These trends can shed light on how well your ads are resonating offline.

You can also leverage tools like call tracking services to keep tabs on phone inquiries generated by your ads. Additionally, analyzing location-specific upticks in customer activity can offer clues about how your ads are impacting foot traffic or in-store visits. By combining these strategies, you’ll get a clearer picture of how your campaign is performing beyond the digital space.

How can I improve the click-through rate (CTR) of my local display ads?

To improve the click-through rate (CTR) of your local display ads, focus on crafting ads that resonate with your audience and are visually compelling. Start by customizing your ads for specific groups based on factors like demographics, interests, or behaviors. Ads that feel relevant to your local community are much more likely to catch someone’s eye.

Use high-quality visuals that stand out and pair them with a clear, action-driven call-to-action (CTA). For example, a phrase like "Claim Your Local Discount Today!" can create a sense of urgency and motivate people to click. Don’t forget to experiment with different headlines, images, and formats. Regular testing and performance analysis will help you refine your approach and consistently improve your results.

When should I focus on ROI versus ROAS for my local display ads?

Deciding between ROI (Return on Investment) and ROAS (Return on Advertising Spend) comes down to what you’re trying to achieve with your business. ROI provides a broader view of profitability by accounting for all expenses, making it a solid choice when you’re evaluating the overall success of your marketing efforts. On the flip side, ROAS hones in on how much revenue your ads generate compared to what you spend on them, making it ideal for analyzing individual campaign performance.

If your focus is on understanding the profitability of your entire marketing strategy, ROI is the metric to lean on. But if you’re looking to tweak your ad budget and get the most out of specific campaigns, ROAS will give you the insights you need. Knowing when to rely on each metric helps you make smarter choices about where to invest and how to improve your local advertising strategy.
