In the ever-evolving world of digital marketing, Facebook remains one of the most powerful platforms for targeted advertising. With billions of active users and a robust advertising ecosystem, it gives businesses a cost-effective way to connect with their audience. At PropelZoom, we believe in data-driven marketing and executing campaigns that deliver real-world results.
This Case Study of Facebook Ad Campaign is a deep dive into how we leveraged Meta’s messaging ads to generate 405 high-quality conversations at an incredibly low cost-per-conversation of $0.04. Yes, you read that right—just four cents per message conversation started.
Through this study, we aim to show our thought process, tools used, strategy execution, and how we optimized for results. If you’re a business owner or marketer looking to scale your reach using Facebook, this campaign blueprint is for you.
Campaign Overview: What We Set Out to Achieve
At PropelZoom, we launched this Facebook ad campaign for our client under the “Inkokzz Engagement Campaign”. The client needed to build direct, one-on-one conversations through Messenger to increase product inquiries, convert more leads, and create personalized user experiences. We focused on Conversation-Driven Marketing rather than just impressions or clicks.
Our primary KPIs for this campaign were:
- Total Messaging Conversations Started
- Cost Per Messaging Conversation Started
- Amount Spent
- Conversion Timeline
Here’s a quick snapshot of our results:
| Metric | Value |
| Messaging Conversations Started | 405 |
| Cost Per Conversation Started | $0.04 |
| Total Spend | $15.43 |
| Campaign Duration | Jan 1 – Jan 25 |
These results were achieved with laser-focused targeting, compelling ad creatives, and continuous optimization throughout the campaign period.
Phase One: Strategic Planning & Audience Targeting
Before launching any ad, we go deep into market research. The Facebook ecosystem offers tools that allow hyper-targeting, so our first priority was defining the right audience segments. We looked at:
- Demographics (age, location, gender)
- Interests and behaviors
- Past purchase behavior
- Engagement history
We created custom audiences based on website traffic and lookalike audiences using high-value customers. This strategy allowed us to narrow in on potential users most likely to engage via Messenger.
We didn’t just “set it and forget it.” We tested multiple ad sets with different targeting parameters. This included:
- Ad Set A: Interest-based targeting (related niches)
- Ad Set B: Lookalike audiences of website visitors
- Ad Set C: Retargeting users who engaged with the page in the last 30 days
This methodical segmentation helped ensure our budget was spent wisely. Within just a few days, we saw messaging conversations spike without spending more, signaling that we had found the sweet spot.
Key insight: If your audience isn’t responding, your cost will rise. Facebook rewards relevance. The more relevant your ad, the lower your cost-per-result.
Phase Two: Crafting the Right Creative & Message
Once we locked in the audience, we knew the creative had to do the heavy lifting. We focused on two key principles for Facebook creatives:
- Visual Impact
- Emotional Resonance
We used a clear call-to-action (CTA) that invited users to start a conversation with a promise of value—whether it was a product discount, quick consultation, or help with selection. The ad copy was tailored to speak directly to the user’s need, with words like:
- “Let’s Chat Now”
- “Need Help Choosing?”
- “Message Us for Exclusive Deals”
These direct, human-centric CTAs aligned perfectly with the goal of driving Messenger engagement. We also added message templates in the ads to guide users into a conversation funnel rather than letting them bounce after a simple hello.
One of the most impactful elements was using carousel ads showcasing product benefits with “Message Now” buttons on each card. This visual variety increased user interaction and gave people options to engage.
Lesson Learned: When your ad feels like a real conversation starter, not a sales pitch, people respond.
Phase Three: Tracking, Optimization, and Scaling Results
In the first 10 days of the campaign, we ran a sub-test (shown in the second screenshot of the campaign titled “Inkokzz Engagement”) that generated:
- 74 Messaging Conversations
- $0.05 per Conversation
- $3.86 Total Spend
This was a testing phase, where we compared multiple creatives and delivery settings. We analyzed performance daily and removed underperforming variants. The best-performing ad was then scaled in the main campaign (first screenshot), which ultimately led to:
- 405 Conversations
- $15.43 Spend
- $0.04 per Conversation
Once we validated performance, we scaled the budget gradually—not all at once—to avoid disrupting the ad learning phase. We maintained consistent engagement levels by adjusting:
- Ad delivery time slots
- Audience freshness (adding new interest groups)
- Creative refresh every 5–7 days
This approach allowed us to sustain low costs while increasing volume—a difficult balance that many campaigns fail to maintain.
Analyzing the Numbers: Why $0.04 CPC Is a Game-Changer
When we saw the final results—405 conversations generated with just $15.43 spent—it reaffirmed that conversation-based marketing is not just effective, it’s scalable. Achieving a $0.04 cost per conversation in today’s digital ad landscape is rare, especially considering increasing CPMs and competitive bidding environments.
Let’s break down the implications of this cost structure:
| Metric | Benchmark Average | PropelZoom Campaign Result |
| Average CPC for Messenger Ads | $0.20 – $0.70 | $0.04 |
| Average CPM | $5 – $12 | Below Industry Average |
| ROAS Potential (Based on Lead Value) | Moderate to High | Very High |
This Case Study of Facebook Ad Campaign demonstrates how strategic execution, creative optimization, and audience accuracy can produce high engagement at minimal cost.
If each conversation has even a 10% conversion rate, and the client’s average order value is $50, the ROI becomes extraordinary. For a $15 ad spend, 40+ quality leads can potentially return $200–$300 in revenue, resulting in a 10x–15x ROAS.
These aren’t just marketing numbers—they’re proof that when strategy meets execution, results follow.
Lessons Learned: What Made This Campaign So Effective
We believe every campaign teaches something. This Case Study of Facebook Ad Campaign gave us rich insights into what works (and what doesn’t) when running high-performance ads on Meta platforms.
Here’s what stood out as key success factors:
- Audience Warmth: Lookalikes and retargeting consistently outperformed cold audiences.
- Fast Optimization: Monitoring and removing poor performers early prevented budget leaks.
- Simple Messaging: The clearer the CTA, the better the response.
- Human-Like Interaction: Ads that felt like they were written by people—not brands—got better engagement.
It’s also worth noting that platform algorithms favor quick action. By reacting to performance in real time (rather than waiting days), we stayed ahead of the curve and protected ad efficiency.
Pro tip: Use Messenger conversation ads when the sales process is personalized. It builds relationships and opens doors to upselling.
