San Antonio: Find a Google Ads Expert (Ultimate Guide)

Thinking about outsourcing your Google Ads in San Antonio is a big step. The first instinct for most business owners is to search for someone local, someone you can meet for a coffee down at The Pearl. But honestly, that's probably the wrong way to look at it. The most important question isn't "who's the best agency in Bexar County?" but rather "who is the absolute best expert in the world at getting customers for a business exactly like mine?" Sometimes that person is in San Antonio, but often they're in Austin, New York, or even across the pond like me.

The goal isn't to find a local vendor; it's to find a strategic partner who understands your customer's pain and knows how to use Google Ads to solve it profitably. This guide is designed to walk you through how to find that partner, whether they're based near the Alamo or not. We'll cover how to vet them, what to really expect in terms of cost, and the tough questions you need to ask to avoid getting burned by someone who just talks a good game.

So, what should I actually be looking for in a San Antonio agency?

Let's get one thing straight: proximity is not a substitute for expertise. I've seen San Antonio businesses hire a local agency that primarily handles restaurants for their complex B2B software campaign. It was a disaster. The agency didn't understand the long sales cycle, the decision-making process, or the language of the customer. They wasted thousands of dollars before the founder realised their mistake.

The first filter you should apply is niche specialisation. San Antonio has a unique economy driven by major sectors like healthcare (think Methodist Healthcare System, CHRISTUS Santa Rosa), military and defense contractors (with Joint Base San Antonio being so huge), tourism, and advanced manufacturing. An agency that has experience scaling a medical device company in Houston will have a massive head start on understanding your challenges compared to a local generalist who’s been running ads for River Walk hotels.

When you're looking at an agency's website, ignore the flashy graphics and go straight to their case studies. This is where the truth lives. Don't just look for big revenue numbers. Look for context.

-> Are the case studies for businesses similar to yours? Same industry, similar size, similar target customer?
-> Do they talk about the actual problem they solved? "Increased traffic" is meaningless. "Reduced cost per qualified lead for high-value surgical consultations by 45%" is what you want to see.
-> Are the results specific and meaningful? A "1000% Return On Ad Spend" sounds great, but without context, it's just a number. For one of our clients, a medical job matching platform, we reduced their Cost Per User Acquisition from an unsustainable £100 down to just £7. That's a specific, impactful result. A trustworthy agency will provide that level of detail, explaining the 'how' behind the 'what'. If their case studies are vague, it's a huge red flag. They're either hiding something or they don't actually understand what drove the results.

The vetting process is critical. If you're a founder, you don't have time to waste on the wrong hire, so getting this right upfront is everything. A good starting point is to understand exactly what the process for vetting and hiring an agency should look like, from initial research to making the final decision.

And when you get them on an introductory call, your job is to listen for real expertise. Do they ask smart questions about your business, your margins, your sales process, your customers? Or do they just launch into a pitch about their "proprietary process"? Experts diagnose before they prescribe. A sales person just tries to sell you a bottle of pills. If it feels like they don't have the expertise you need after you've done your homework, it's not a good fit. Trust your gut.

How do I figure out my budget? What does this stuff actually cost in Texas?

This is the question that trips up almost everyone. Business owners often think in terms of "I have $2,000 a month for marketing." But that's backwards. The question isn't what you have, but what you can afford to spend to acquire a customer and still be very profitable. To figure that out, you need to understand two of the most important acronyms in business: LTV (Lifetime Value) and CAC (Customer Acquisition Cost).

Your LTV is the total profit you can expect to make from a single customer over the entire time they do business with you. Your CAC is what you spend to get that customer. A healthy business typically has an LTV:CAC ratio of at least 3:1. Meaning for every dollar you spend on marketing and sales, you get at least three dollars back in profit over the customer's lifetime. Knowing this number is your superpower. It tells you exactly how much you can bid on keywords and how aggressive you can be.

Let's run the numbers. Forget guesswork; let's calculate it. I've built a simple calculator below to help you figure this out for your own business.

Once you know you can afford to spend, say, $4,667 to acquire a customer, everything changes. If your sales team closes 1 out of every 10 qualified leads, you can now afford to pay up to $467 per lead. Suddenly, a $60 cost per lead for an HVAC company in a competitive San Antonio summer doesn't seem so bad, does it? It looks like a bargain.

This is the math that unlocks scale. Without it, you're just guessing. With it, you can build a predictable growth engine. This is probably the most crucial part of the playbook for measuring and maximizing your paid ads ROI.

As for typical costs, they vary wildly. For a local service business, you might see leads from $20-$80. For competitive B2B or legal keywords, it could be hundreds of dollars per click. We’ve seen childcare services get signups for around $10. The key is not the cost per lead, but the cost per *acquired customer* and how that stacks up against your LTV. That's the only thing that matters.

What questions should I ask to avoid getting burned?

The introductory call with a potential agency is your chance to cut through the sales pitch. Most business owners ask the wrong questions, like "what's your pricing?" or "what results can you guarantee?". These are easy to answer with fluff. You need to ask questions that reveal their actual competence and character.

Here are a few I'd recommend, designed to make a salesperson squirm but an expert light up:

1. "Forget your biggest win for a moment. Walk me through a campaign for a client like me that went wrong, and tell me exactly what you learned from it."
This is my favourite. It tests for honesty, humility, and a capacity to learn. Every single expert has run campaigns that have failed. It's part of the process. How they respond to and learn from that failure is what separates the pros from the amateurs. If they claim they've never had a campaign fail, they're either lying or they're too inexperienced to be worth your time.

2. "My last agency was obsessed with clicks and impressions. How will you measure and report on the success of my campaigns in terms of actual business results?"
This question forces them to talk about what matters: leads, sales, revenue, and profit. You want to hear them talk about tracking conversions, connecting their work to your CRM data, and focusing on metrics like Cost Per Qualified Lead or Return On Ad Spend (ROAS). If they start waffling about 'brand awareness' for your plumbing business, it's a bad sign. You're not Coca-Cola; you need the phone to ring.

3. "What does your process for keyword research and ad copy testing look like for a business in the [your industry] space in San Antonio?"
This tests their process and strategic thinking. A good answer will involve talking about competitor analysis, understanding search intent (the difference between someone searching "how to fix leaky faucet" vs "plumber near 78209"), and a structured approach to testing different headlines and descriptions. A bad answer is vague and full of buzzwords like "we use AI-powered optimisation."

The whole vetting process can feel overwhelming, but you can break it down into a simple, repeatable process.

Finally, watch out for red flags. Anyone guaranteeing results is a massive one. Paid advertising is an auction; you can't guarantee anything. Long-term contracts (more than 3 months to start) are also a concern. A confident agency knows they can deliver results and doesn't need to lock you in for a year. The entire process of managing your agency relationship after the hire is just as important as the hiring itself, and it's something many founders overlook until it's too late. There is a whole framework for managing agencies to ensure you get the maximum return on your investment.

Okay, I've hired someone. Now what?

Signing the contract is the start, not the finish line. How you manage the relationship in the first 90 days will set the tone for the entire partnership. The most common mistake I see business owners make is expecting immediate, spectacular results. It just doesn't work that way.

Paid advertising is a process of testing and learning. The first month is often about setting up tracking correctly, launching initial campaigns based on research, and gathering data. You might not see a positive return right away, and that's normal. The goal is to collect data on what's working and what isn't, so you can make intelligent decisions. It's an iterative process, not a magic button.

Here’s a realistic look at what the first 90 days should look like:

Your role as the business owner is crucial here. You have to provide feedback. The agency doesn't know which leads are good and which are tire-kickers unless you tell them. A weekly or bi-weekly check-in is essential to review the leads and discuss what's happening on the sales side. This feedback loop is what allows a good agency to refine targeting and ad copy to attract more of your ideal customers. This is a partnership. If you just hand over the keys and expect them to figure it all out in a vacuum, you're setting yourself up for disappointment.

Communication is also massive. You should expect a clear report at least monthly that focuses on the metrics you agreed were important. It should be easy to understand and clearly show the spend, the results (leads/sales), the cost per result, and the return. If you're getting a 20-page PDF full of jargon and charts about click-through rates, push back. Demand clarity and focus on the bottom line.

What kind of strategy should a good agency propose for a San Antonio business?

A good strategy is never one-size-fits-all, but it should always be based on your specific business model and customer. Let's look at two common San Antonio business types.

For a Local Service Business (e.g., Plumber, Electrician, HVAC in Alamo Heights):
The strategy should be laser-focused on capturing intent. You want to show up when someone's AC breaks in the middle of July or their pipes burst. This means Google Search Ads are your best friend.

-> Campaigns: The account should be tightly structured. You might have one campaign for "Emergency Services" targeting keywords like "emergency plumber san antonio" and another for "General Services" with keywords like "drain cleaning near me" or "water heater installation".
-> Keywords: They should be using location-specific keywords and even targeting specific zip codes (like 78209 for Alamo Heights or 78258 for Stone Oak). Broad keywords are a waste of money.
-> Ad Copy: The ads must speak to the local customer. "Serving San Antonio for 20+ Years," "24/7 Emergency Service in Bexar County," and mentioning specific neighborhoods shows you're a legitimate local company.
-> Extensions: Call extensions are non-negotiable so people can call you directly from the ad. Location extensions are also vital to show up on the map. They might also suggest Local Service Ads (the Google Guaranteed listings), which can be brilliant for trades.

Here’s a simplified look at what a good structure might look like:

For a B2B Company (e.g., Manufacturing Tech, SaaS, Professional Services):
The strategy is often more complex. You're not just looking for a quick phone call; you're trying to start a longer conversation with a specific type of decision-maker.

-> Audience Intent: The focus is still on search intent, but the keywords will be different. Instead of "near me," you're targeting problem-aware keywords like "supply chain management software" or solution-aware keywords like "oracle netsuite alternative."
-> The Offer: You're probably not selling your service directly from an ad. The goal is to generate a qualified lead. This usually means driving traffic to a specific landing page with a compelling offer, like a free demo, a case study download, a webinar registration, or a free consultation. The "Request a Demo" button is often not enough; you need to offer genuine value upfront.
-> Landing Pages: These are non-negotiable. Sending high-cost B2B traffic to your generic homepage is like lighting money on fire. Each campaign needs a dedicated landing page that speaks directly to the pain point of the person who clicked the ad.

For these kinds of high-value services, the strategy can get very detailed. There is an entire methodology to mastering Google Ads for high-ticket B2B services, which involves a deep understanding of the customer journey and building full-funnel campaigns. The key takeaway is that a good agency will propose a strategy that is custom-built for your business model, not a cookie-cutter template.
