Latino Community
Client Since Jun 2025
Attorney Fernando Hidalgo has been serving the Hispanic community in the San Francisco Bay Area for over 19 years.
Bilingual by profession, English-speaking by background, he built his practice on being accessible to a community that often struggles to find legal representation that speaks their language and understands their situation. Immigration, workers’ compensation, and personal injury cases are where the stakes for his clients are at their most personal.
He had everything in place to run strong Facebook campaigns: a recognizable face, a compelling story, real client results, and an audience that responds to someone who speaks to them directly in Spanish.
What he didn’t have was a proper campaign structure. His team was running ads through Facebook’s “Boost Post” button, a tool that looks like advertising but lacks the targeting precision, optimization controls, and conversion tracking that Ads Manager provides.
When we got access to the account in June 2025, the Ads Manager was completely empty. There were no campaigns, no ad sets, no conversion data, nothing to build on. We were starting from zero.
THE PROBLEM
Boost Posts Are Not Facebook Ads, And the Difference Costs Real Money
This is a distinction that matters more than most people realize. Facebook’s Boost Post feature is designed for simplicity; you pick an audience, set a budget, and hit go. But that simplicity comes at a cost.
You lose access to the campaign objectives that matter for lead generation, the audience segmentation tools that get your ad in front of the right people, the placement controls that optimize for where your audience actually spends time, and the conversion tracking that tells you what’s actually working.
For a law firm whose clients are predominantly Spanish-speaking immigrants in specific Bay Area cities, people with very particular circumstances and needs, running generic boosted posts was leaving a significant amount of money and leads on the table every single week.
BEFORE: BOOST POSTS
What The Team Was Doing
- ❌ Boosting posts from the Facebook page with basic audience settings
- ❌ No campaign objectives optimized for lead generation or messaging
- ❌ No retargeting, people who saw the ad but didn’t message were lost forever
- ❌ No A/B testing of creative, copy, or audiences
- ❌ No data history to optimize from, every week starting blind
- ❌ No separate campaigns by case type or audience segment
After: Proper Ads Manager
What We Built
- ✅ Messaging campaigns optimized specifically for WhatsApp conversations
- ✅ Separate ad sets targeting different case types and audience segments
- ✅ Direct WhatsApp button in every ad, one tap to start a conversation
- ✅ Attorney video ads in Spanish speaking directly to each specific situation
- ✅ Static image ads for each practice area with clear, direct messaging
- ✅ Weekly performance tracking to optimize budget and creative continuously
THE STRATEGY
The Attorney Is the Ad And WhatsApp Is the Door
The creative strategy was built around two things that work particularly well for this community: the attorney’s face and voice, and the frictionless path to a conversation.
Every ad features Fernando Hidalgo speaking directly to the camera in Spanish, with short videos of 10 to 22 seconds recorded at his office and in front of his storefront, addressing the exact fear or question that each specific audience segment is facing.
Someone who might qualify for residency through a US citizen spouse. A victim of domestic violence who could qualify for VAWA. Someone who experienced workplace discrimination. A person who was a victim of a crime and could qualify for a Visa U.
Each situation got its own ad. Each ad ended with one call to action: message us on WhatsApp. When someone taps that button, a case manager immediately picks up the conversation. The barrier between “saw the ad” and “talking to someone at the firm” is as low as it can possibly be.
The Hispanic immigrant community makes decisions based on trust built through direct communication. A 15-second video of the attorney speaking your language, addressing your exact situation, and inviting you to message him on WhatsApp is worth more than any polished landing page.
We ran multiple campaigns simultaneously a general immigration campaign targeting anyone who might need immigration help in the Bay Area, plus specific campaigns for residency, VAWA, Visa U, and workplace discrimination. The budget stayed around $1,000 per week across all campaigns.
THE RESULTS
9 Months of Data: A Rocky Start, Then a Machine That Runs
Here’s the honest version of what happened, because every account has a learning curve, and this one was no exception.
$96/Lead
Worst Week
The rough start, a technical problem, and a spike in costs
June – July 2025
The first week produced 65 leads at a solid $19/lead, a strong opening. But the following week, a WhatsApp phone number verification issue caused the messaging campaigns to malfunction, and the cost per lead spiked to $96.47 for just 3 leads.
Once the technical issue was resolved, the campaigns stabilized, and leads returned to normal volume within days. This is the kind of problem that’s invisible when running boost posts; in Ads Manager, we could see what was happening and fix it immediately.
23–40
Leads/Week
The optimization period, finding the right audience and creative mix
August – September 2025
August and September saw leads dip to 23–40 per week as we tested different audience segments, ad formats, and copy variations. Cost per lead climbed to $25–42 during this period.
This is normal and necessary; the campaigns were learning which audiences responded best to which creative. The data we gathered here is what powered the consistent performance that followed.
47–73
Leads/Week
Consistent performance. The campaigns hit their stride
October 2025 – March 2026
From October onward, the account delivered consistent results week after week. Leads averaged 47–73 per week, cost per lead settled into the $13–21 range, and the best single week, the last week of December 2025, produced 73 leads at $12.85 each.
That consistency is the goal. Not one exceptional week, but a system that reliably fills the firm’s pipeline every week without exception.
73
Most leads in a single week: Dec 30, 2025 to Jan 4, 2026

The Takeaway
The Right Tool Makes the Difference Even When You’re Already Running Ads
This case study isn’t about a business that had no online presence. Fernando Hidalgo already had ads running, and his team was already spending money on Facebook. The difference wasn’t the budget; it was the tool and the strategy behind it.
Boost posts get your content in front of people; proper campaigns get your message in front of the right people, with the right call to action, at the right moment, and then give you the data to keep improving every single week. That difference, compounded over 9 months, is the gap between 3 leads in a bad week and 73 leads in a great one.
The campaigns are still running, leads are coming in, and WhatsApp conversations that start with an ad are turning into real clients for a firm that has spent 19 years earning the community’s trust, one case at a time.
