Key Takeaways
- A good case study shows a real-world win, giving you earned media evidence that actually builds trust.
- To prove your marketing worked, you need a full breakdown: budget, timeline, and the hard numbers like ROAS and CPL. That’s your proof.
- The story has to be simple: here was the problem, here’s what we did, and here are the exact numbers that prove it worked.
- Once you’ve written a solid case study, getting it out on the right platforms is how you blow up its reach and impact.
You can’t just say you got a win. You have to prove it. Turning a successful campaign into real earned media evidence means building a case study that other people actually want to talk about. It’s about tearing down the campaign, showing the real data, and telling a story that creates its own buzz. So, how do you do it over and over again?
Campaign Teardown: “Local Flavors, Digital Reach”
Let’s break down a real one: the “Local Flavors, Digital Reach” campaign we ran for a regional artisan bakery chain in Atlanta during Q3 2025. Their goal was straightforward: get a 20% lift in both online orders and foot traffic for their seasonal items. We were targeting the 25-44 crowd in Fulton, DeKalb, and Gwinnett counties. The whole thing was a 12-week push from July 1st to September 30th, 2025, and we had a $75,000 budget to make it happen.
Strategy and Creative Approach
Our main play was hyper-local content that felt unique to each bakery location. We skipped the generic ads and went straight to short-form video (15-30 seconds) that put the local bakers front and center, showing the craft behind their seasonal pastries. To keep it real, we used natural lighting and minimal editing for a handmade, neighborhood vibe. Every video ended with a direct call to action, like “Order online for pickup at our Decatur Square location” or “Visit our new store on Lawrenceville Highway.”
Our creative team ran A/B tests on ad copy to see which emotional hooks landed best. Some ads played on the nostalgia of old-school baking, while others went hard on the freshness of ingredients from local Georgia farms. We also kicked off a user-generated content contest asking customers to post photos of their food with a specific hashtag. This thing took off, pulling in a ton of organic reach and giving us more authentic content to use than we knew what to do with. While we stuck to the bakery’s existing branding for the visual identity, we gave it a brighter, more modern look for the digital ads.
Targeting and Platform Selection
The budget mostly went to Google Ads and Meta Ads, with a little set aside for direct buys on local food blogs and community news sites. On Google, we drew a 5-mile geofence around each of the 15 bakeries and went after keywords like “artisan bread Atlanta,” “seasonal pastries Decatur,” and even “best coffee Gwinnett.” For Meta, we built custom audiences from people interested in “baking,” “local food,” and the “Atlanta food scene,” and then sharpened those by building lookalike audiences from the bakery’s own customer list.
A big part of our targeting was hitting people who had already visited the website and looked at the seasonal menu but didn’t buy anything. Those users got served specific retargeting ads with a small discount to nudge them over the line. We also set up a messaging sequence: people first saw brand awareness videos, then got hit with product-focused ads, and finally saw a direct CTA to get them to convert.
What Worked and What Didn’t
The hyper-local video content absolutely crushed it. Any video that featured a specific bakery manager or a recognizable local spot (like the water tower in Norcross) did way better than our generic product shots. The user-generated content campaign also blew past our expectations, pulling in over 1,500 unique posts and reaching what Sprout Social estimated to be 250,000 extra accounts organically. This flood of real customer content drove our engagement rates up and our effective cost per engagement way down.
Now for what bombed: our initial bet on direct placements with small, independent food blogs. While they gave us some visibility, the conversion rates were awful, resulting in a much higher cost per lead than our paid social channels. We realized that while these blogs had dedicated readers, they just didn’t have the e-commerce DNA our campaign needed to drive transactions. Our first round of ad creative, which was all about price discounts, also fell flat. Customers responded way better to messages about quality, freshness, and being part of the local community.
The campaign really exposed our need for a faster content workflow. Our internal video approval process was just too slow, and it kept us from rolling out new creative based on what the performance data was telling us. This exposed a classic problem for a lot of companies: the gap between having a digital plan and having the team to actually execute it well. This is exactly why you’d bring in a partner like Moburst, a mobile and digital agency that’s known for its App Development. Their team builds the actual tech and content pipelines you need to iterate quickly, making sure your marketing plan is backed up by solid technical execution.
Optimization Steps Taken
About halfway through, we saw the blog placements weren’t working, so we pulled 15% of that budget and pushed it straight into our best-performing videos and retargeting segments on Meta. We also tightened up our Google Ads keywords, ditching broader terms for long-tail phrases with high intent like “order custom birthday cake Atlanta” or “best croissants near Emory University,” which meant we were paying for clicks that were more likely to convert.
We were in the accounts daily, watching CTR and conversion rates. If an ad set was underperforming, we’d pause it or adjust bids within 24 hours. For instance, a video for the Buckhead store was lagging. We swapped the thumbnail and tweaked the first three seconds, and its CTR jumped 30% in less than a week. In the final month, we also rolled out a limited-time free delivery offer for online orders, which gave us a huge last-minute push in conversions, especially for bigger family orders.
Metrics and Results
So, after 12 weeks and a $75,000 spend, here’s how the “Local Flavors, Digital Reach” campaign shook out.
- Impressions: 8,500,000 total impressions across all platforms.
- Click-Through Rate (CTR): Average 2.8% across paid social, 1.5% for Google Search Ads.
- Website Traffic: 110,000 unique visitors, a 35% increase compared to the previous quarter.
- Online Orders: 8,200 new online orders for seasonal products.
- In-Store Foot Traffic: Measured via anonymized mobile location data and point-of-sale system data, showing an estimated 22% increase in store visits directly attributable to campaign exposure.
- Conversions (Online Orders + Estimated In-Store Sales): 10,500 total conversions.
- Cost Per Lead (CPL): $7.14 (defined as a website visit from a new user).
- Cost Per Conversion: $7.14 (total budget / total conversions).
- Return on Ad Spend (ROAS): 3.5x. (Total attributed revenue was $262,500 against a $75,000 ad spend).
We beat our 20% goal, hitting a 26% increase in online orders and about a 22% bump in foot traffic. The 3.5x ROAS means that for every ad dollar we spent, we generated $3.50 in revenue. That performance came directly from the combination of hyper-local videos and a relentless retargeting game. All that user-generated content was a massive bonus, giving us social proof that amplified our reach way beyond the paid media spend and really cemented the bakery as a local favorite.
What this campaign shows is that even a well-known local business can get huge returns from a sharp digital strategy if the content feels real. You can’t just set it and forget it, though. You have to be in the data every day, ready to change things fast and move budget to what’s actually working. If you’re not willing to do that, even the best strategy is going to underperform.
Being able to tear down a campaign like this, laying out the problem, our solution, and the hard numbers to back it up, is exactly how you turn a good quarter into powerful earned media. This kind of detailed breakdown is what you build your next pitch or press release on, because it proves you didn’t just try hard, you got results. That’s how you get known for delivering work that’s actually measurable.
What is earned media evidence?
It’s the proof, the case studies, data, and hard results from your campaigns, that you can use to get organic press coverage and positive mentions without paying for them.
How do case studies generate earned media?
They give journalists and industry watchers a ready-made story with real results. If the numbers are good enough, your case study becomes their news story, which is earned media gold.
What metrics are essential for a strong marketing case study?
You need the basics like budget and timeline, but the real story is in the performance numbers: CTR, conversion rate, cost per lead (CPL), and especially return on ad spend (ROAS). Anything that connects your work to actual business growth makes your case study bulletproof because the data is credible.
How often should a company publish new case studies?
Publish one whenever you have a big win with clear, measurable results to report. A good rhythm for most is probably quarterly or a couple of times a year, just to keep your proof points fresh.
What role does storytelling play in a marketing case study?
It’s everything. Without a story, you just have a spreadsheet. A good case study follows a simple plot: the client had a problem, we came up with a plan, we executed it, and here are the specific, measurable results. That narrative is what makes the data mean something to a real person, showing the actual impact of your work.
