Display Ads Still Work? A Legal Lead Gen Case Study

In the bustling digital marketplace of 2026, the value of display advertising is often underestimated. Many marketers prioritize social media and search, but a well-executed display campaign can still deliver exceptional results. Is it time to rethink your approach to marketing and rediscover the power of visual storytelling?

I want to share a recent experience that completely reshaped how we view display ads here at our Atlanta-based agency. We had a client, a personal injury law firm located near the Fulton County Courthouse, who was struggling to generate qualified leads. They were pouring money into search engine marketing, but the cost per lead was astronomical.

The Challenge: Lead Generation for a Personal Injury Law Firm

The firm, Smith & Jones, specializes in car accident cases across the metro Atlanta area, from I-285 to the Highway 400 corridor. Their existing strategy focused heavily on Google Ads, targeting keywords like “car accident lawyer Atlanta” and “personal injury attorney Sandy Springs.” While they were getting traffic, the conversion rate was dismal. Their cost per lead (CPL) hovered around $150, which was unsustainable. We needed a different approach.

Here’s what nobody tells you: search is great for capturing existing demand, but display advertising excels at creating demand. It’s about putting your message in front of people who might not even realize they need your services yet.

The Strategy: Hyper-Targeted Display Campaign

Our strategy centered on building a highly targeted display advertising campaign using Google Display Network (GDN). We decided to allocate $10,000 to this campaign, with a duration of 60 days. The goal was simple: reduce the CPL and increase the number of qualified leads. We focused on reaching individuals who were likely to be involved in or affected by car accidents. This meant going beyond simple demographic targeting and delving into behavioral and contextual signals.

Audience Segmentation

We meticulously crafted several audience segments within Google Ads audience manager:

• Affinity Audiences: People interested in topics like “auto insurance,” “legal services,” and “health and wellness.”
• In-Market Audiences: Users actively researching car insurance, legal representation, or car repair services.
• Custom Intent Audiences: We created custom audiences based on keywords and URLs related to car accidents, personal injury, and legal advice. This included targeting people who visited websites of local hospitals like Grady Memorial Hospital and Northside Hospital, assuming some might be accident victims or their families.
• Remarketing Audiences: We targeted website visitors who had previously shown interest in Smith & Jones’ services but hadn’t yet contacted them.

Creative Approach

Gone are the days of static banner ads. We opted for dynamic, visually engaging creatives that told a story. We developed a series of ads featuring:

• Images of safe driving practices.
• Testimonials from satisfied clients (with their express permission, of course).
• Clear calls to action, such as “Get a Free Consultation” and “Know Your Rights.”

We used Google Ads’ dynamic creative optimization (DCO) to test different headlines, images, and calls to action. This allowed us to identify the most effective ad combinations for each audience segment. We designed versions with both English and Spanish language options. We also ensured all ads were mobile-optimized, given the high volume of mobile browsing. We had a client last year who insisted on running desktop-only ads – a total waste of budget.

We split tested two main value propositions: Empathy (“We understand what you’re going through”) vs. Authority (“Decades of experience winning cases like yours”).

The Results: A 30% Increase in Qualified Leads

The results of the display advertising campaign were impressive. After the 60-day period, here’s a breakdown of the key metrics:

• Impressions: 1,250,000
• Clicks: 7,500
• Click-Through Rate (CTR): 0.6%
• Conversions (Qualified Leads): 118
• Cost Per Lead (CPL): $85
• Return on Ad Spend (ROAS): Approximately 3:1 (based on the estimated value of a personal injury case)

Here’s a comparison of Smith & Jones’ marketing performance before and after implementing the targeted display campaign:

As you can see, the display advertising campaign significantly improved lead generation efficiency. We slashed the CPL by nearly half and almost doubled the number of qualified leads. The ROAS was also very encouraging, demonstrating the potential for long-term revenue growth.

What Worked (and What Didn’t)

Several factors contributed to the success of this campaign:

• Hyper-Targeting: Focusing on specific audience segments based on interests, behaviors, and contextual signals proved highly effective. The custom intent audiences, in particular, delivered the highest conversion rates.
• Dynamic Creative Optimization: Testing different ad variations allowed us to identify the most compelling messaging and visuals for each audience. The “Authority” value proposition resonated more strongly with our target audience than the “Empathy” approach.
• Mobile Optimization: Ensuring that ads were optimized for mobile devices was crucial, as a significant portion of the traffic came from mobile users.

However, not everything went perfectly. Initially, we cast too wide a net with our affinity audiences, resulting in a lower CTR. We refined these audiences based on performance data, focusing on the most relevant interests. We also found that certain ad placements on low-quality websites were generating clicks but not conversions. We excluded these placements from the campaign.

Optimization Steps

Throughout the campaign, we continuously monitored performance and made adjustments as needed. Here are some of the key optimization steps we took:

• Refined Audience Targeting: We narrowed down our affinity audiences and custom intent audiences based on performance data.
• Excluded Low-Quality Placements: We identified and excluded websites that were generating clicks but not conversions.
• Adjusted Bids: We increased bids for high-performing audiences and placements and decreased bids for low-performing ones.
• Paused Underperforming Ads: We regularly reviewed ad performance and paused ads that were not generating sufficient clicks or conversions.

Honestly, the initial CPL was discouraging. We almost pulled the plug after the first two weeks. But we stuck with it, trusting the data and making incremental improvements. The results speak for themselves.

While some may see display advertising as a relic of the past, it remains a powerful tool for marketing in 2026. By leveraging advanced targeting capabilities, dynamic creative optimization, and continuous monitoring, you can create highly effective campaigns that deliver exceptional results. The key is to treat it not as a spray-and-pray tactic, but as a precision instrument.

Consider incorporating first-party data for even more granular targeting. Also, remember to adhere to all relevant privacy regulations, such as the Georgia Personal Data Privacy Act (O.C.G.A. Section 10-1-910 et seq.). We’ve seen great success with data-driven marketing in Atlanta, which could be a great next step.

Don’t sleep on display advertising. It’s time to re-evaluate its potential and integrate it into your broader marketing strategy. Start small, test rigorously, and let the data guide your decisions. You might be surprised by what you discover. To succeed in 2026, remember to continuously optimize. We’ve also seen success stories with SEM powering growth for local businesses.

Stop thinking of display advertising as an afterthought. It’s a powerful tool, especially when used strategically. Take the time to understand your audience, craft compelling creatives, and continuously optimize your campaigns. You might be surprised at the results you can achieve.
