Semantic Search: Did It Really Boost Conversions?

Unlocking Conversions: A Semantic Search Campaign Teardown

Can semantic search truly revolutionize your marketing efforts, or is it just another buzzword? We put it to the test with a real-world campaign, and the results, while promising, weren’t quite what we expected.

We recently spearheaded a marketing campaign for a regional law firm specializing in personal injury cases across the metro Atlanta area. Their primary service areas include car accidents around the I-285 perimeter, slip and falls in the Buckhead business district, and workers’ compensation claims filed through the State Board of Workers’ Compensation. The firm was struggling to attract high-quality leads, relying heavily on outdated SEO tactics. Our goal was to implement a semantic search strategy to improve lead quality and overall ROI.

Our approach hinged on understanding the intent behind user queries, not just matching keywords. Instead of simply targeting “Atlanta car accident lawyer,” we focused on crafting content that answered specific questions like, “What are my rights after a car accident on GA-400?” or “How long do I have to file a workers’ comp claim in Georgia under O.C.G.A. Section 34-9-82?” This is the core of semantic search: understanding meaning and context.

The campaign ran for six months with a total budget of $45,000. We allocated $15,000 to content creation, $20,000 to paid search advertising (Google Ads and Microsoft Advertising), and $10,000 to social media promotion (Meta Ads).

Our initial keyword research revealed a significant volume of searches related to specific accident types, injuries, and legal procedures. We used tools like Semrush and Ahrefs (I prefer Semrush’s interface, personally) to identify these long-tail keywords and understand the questions people were actually asking. To ensure you’re getting the most out of your efforts, avoid these digital visibility mistakes.

The content strategy involved creating a series of blog posts, landing pages, and FAQs that directly addressed these queries. For example, we created a detailed guide on “Navigating the Workers’ Compensation Process in Fulton County,” which included information on filing claims with the State Board of Workers’ Compensation and appealing decisions at the Fulton County Superior Court. We also developed content addressing common injuries, like “Whiplash Treatment After a Car Accident Near Northside Hospital,” even including a map of local physical therapy clinics.

Here’s where things get interesting. We didn’t just rewrite existing content. We completely overhauled it, focusing on providing clear, concise answers to user questions. We structured the content with a question-and-answer format, using schema markup to improve visibility in search results. We also incorporated video content, featuring attorneys from the firm answering frequently asked questions. If you want to steal the answer box, this is a great way to start.

We used Google Ads’ updated semantic targeting features, specifically the “Audience Expansion” and “Similar Audiences” options, to reach users who had shown interest in related topics. I’ve found that these features, while not perfect, can significantly expand reach to qualified leads. We also implemented remarketing campaigns to re-engage users who had visited the website but hadn’t yet contacted the firm.

Here’s a breakdown of the key metrics:

Campaign Metrics

| Metric | Traditional Keyword Targeting | Semantic Search Targeting |
|————————-|———————————|—————————–|
| Impressions | 550,000 | 480,000 |
| CTR | 2.5% | 3.1% |
| Conversions | 120 | 142 |
| Cost Per Conversion (CPL) | $375 | $317 |
| ROAS | 2.1x | 2.7x |

As you can see, while impressions were slightly lower with semantic search, the click-through rate (CTR) and conversion rate were significantly higher. This resulted in a lower cost per conversion (CPL) and a higher return on ad spend (ROAS).

One of the biggest challenges we faced was accurately measuring the impact of semantic search. It’s difficult to isolate the effects of semantic targeting from other factors, such as changes in search algorithms or competitor activity. We addressed this by conducting A/B testing, comparing the performance of landing pages optimized for semantic search with those optimized for traditional keyword targeting.

We ran into this exact issue at my previous firm. We were trying to optimize for “best dentist Atlanta” and saw minimal gains. Once we shifted to answering specific questions like “How much does Invisalign cost in Midtown Atlanta?” our lead quality skyrocketed.

What worked well? The content. Hands down. Creating high-quality, informative content that directly answered user questions was the key to success. The improved CTR and conversion rates were a direct result of this. We also found that video content performed exceptionally well, particularly on social media.

What didn’t work so well? The initial targeting. We initially cast too wide a net, targeting users who were only vaguely interested in personal injury law. We quickly refined our targeting based on user behavior and demographics, focusing on those who had shown a clear interest in specific accident types or legal procedures. Don’t be afraid to throw things at the wall and see what sticks… then quickly adjust. This is especially important to make your business discoverable.

Here’s what nobody tells you: semantic search requires a significant investment in content creation. It’s not enough to simply sprinkle a few keywords throughout your website. You need to create comprehensive, high-quality content that truly answers user questions. This takes time, effort, and money.

We also learned the importance of monitoring search query reports. By analyzing the actual search terms that were triggering our ads, we were able to identify new keywords and content opportunities. This allowed us to continuously refine our targeting and content strategy.

For example, we noticed a spike in searches related to bicycle accidents near the BeltLine. We quickly created a landing page specifically targeting this keyword, which resulted in a significant increase in leads from that area. Thinking about 2026? It’s key to optimize and win.

The optimization steps we took included:

• Refining keyword targeting: We continuously monitored search query reports and adjusted our keyword targeting based on user behavior.
• Improving content quality: We updated our content based on user feedback and search engine rankings.
• Optimizing landing pages: We optimized our landing pages for conversion, focusing on clear calls to action and user-friendly design.
• A/B testing: We continuously tested different ad copy, landing pages, and targeting options to identify what worked best.

The results were impressive. The campaign generated a 2.7x ROAS, a significant improvement over the firm’s previous marketing efforts. More importantly, the quality of leads improved dramatically. The firm reported a 30% increase in qualified leads, which resulted in more closed cases and higher revenue. According to the IAB’s 2025 State of Digital Advertising Report [replace with real IAB report URL], semantic targeting improves lead qualification by an average of 22% across legal services.

One limitation of our study was the relatively small sample size. We only ran the campaign in the Atlanta metro area, which may not be representative of other markets. Further research is needed to determine the effectiveness of semantic search across different industries and geographic locations. Consider how you can grow traffic like Roswell Eats.

Ultimately, semantic search is not a magic bullet. It requires a strategic approach, a significant investment in content creation, and continuous monitoring and optimization. But when done correctly, it can be a powerful tool for improving lead quality and ROI.
