Here’s the deal with A/B testing, straight from me, Cody Ewing at Bruce & Eddy. I promise, no corporate jargon.
- A/B testing is just comparing two versions of something (like a headline or button) to see which one your customers prefer.
- You need a good reason for the test (a hypothesis), and you should only change one thing at a time.
- It’s how you stop wasting money on marketing that doesn't work and start making decisions with actual data.
- We bake this thinking into everything we build—from our BEGO sites for small businesses to the custom web apps my dad, Butch, and our code guru, Anjo, cook up.
- Since 2004, we've helped businesses across Texas (and the U.S.) grow by listening to their customers. It works.
I spend my days talking to business owners, and I hear the same thing constantly: “We tried this, we think that…” The problem is, “thinking” doesn’t pay the bills. Your gut is great for picking a BBQ spot in Lockhart, but it’s a terrible way to build a website that actually makes you money.
Enter A/B testing. It’s the simplest, most effective way to stop guessing. It’s a digital showdown—version A versus version B—where your actual customers pick the winner. No ego, no opinions, just cold, hard facts. And honestly, it’s how we at Bruce & Eddy turn good websites into great ones.
So, What Is A/B Testing Anyway?
Imagine you’re selling jam at a farmers market in a place like Bastrop or Fredericksburg. You’ve got two signs.
Sign 'A' reads, "Handmade Strawberry Jam." It’s direct.
Sign 'B' gets a little creative: "Tastes Like Summer in a Jar."
You show Sign 'A' to half the people who walk by and Sign 'B' to the other half. At the end of the day, you count which sign made more people stop, sample, and buy.
That’s it. You just ran an A/B test.
It's a simple, powerful way to see what your customers actually respond to, not just what you think they'll respond to.
It’s all about swapping guesswork for real data. For the small businesses, nonprofits, and creative folks we work with from Houston to Fort Worth, this isn't some fancy corporate luxury. It's how you stop wasting time and start making smart decisions that lead to growth.
This same idea applies to your website, emails, and ads. Should that "Donate Now" button be red or green? Does a question get more clicks than a statement? A/B testing gives you the answers. For a peek at how this works on a massive scale, check out this guide on A/B testing on Amazon.
My dad, Butch Ewing, co-founded Bruce & Eddy back in 2004 on this principle. He’s the big-picture strategist, and he’s always preached that data, not opinions, should drive your strategy. It’s less about marketing magic and more about methodical, common-sense experiments.
The Simple Ingredients of a Good A/B Test
So you get the jam stand analogy. But a good A/B test isn’t about just tossing up two different signs and hoping for the best. It’s less about flinging spaghetti at the wall and way more about following a proven recipe.
To get results you can actually trust, you need a few key ingredients. Think of it like building a house—you wouldn't start without a blueprint, right?
Your Educated Guess, or Hypothesis
First, you need a hypothesis. That’s just our professional way of saying an "educated guess." It's a clear statement that lays out what you're changing, what you expect to happen, and why.
For instance, a local church in Richmond, Texas might say: “We believe changing our online giving button from 'Donate' to 'Support Our Mission' will increase giving because it connects the action to a greater purpose.”
That’s a perfect hypothesis. It’s specific, testable, and has a clear reason behind it. Without one, you’re just changing things randomly and learning nothing.
Your A and B Versions, or Variants
Next, you need your variants. These are the two versions you'll be comparing. There’s Version A, the control (what you have now), and Version B, the challenger (the new version with the single change).
Let's stick with our church example:
- Variant A: The original page with the "Donate" button.
- Variant B: An identical page, but with the button text changed to "Support Our Mission."
The golden rule here is to only change one thing at a time. If you change the button text, the main picture, and the headline all at once, you’ll have no idea which change actually made the difference. It just muddies the waters.
If you want a deeper dive into how these variants are built on a page, our guide on what makes a great https://www.bruceandeddy.com/what-is-a-landing-page-5/ is a great place to start.
This infographic breaks down the simple flow of an A/B test from beginning to end.
As you can see, you start with your audience, show them the different versions, and then let the data tell you which one performs best.
Getting Enough Data to Matter
Finally, there are two components that sound a bit technical but are really simple: a large enough sample size and statistical significance.
A sample size is just the number of people who see your test. If only 20 people visit your page, the results don’t mean a thing. It's too small a group to draw real conclusions. You need enough traffic to gather reliable data, which usually means running a test for at least a week or two.
Statistical significance is the math that confirms your result is legitimate and not just a random coincidence. It’s the proof that says, "Yes, Version B really is better, and we have the numbers to back it up."
To make sure your tests are designed for success, it helps to follow a winning creative testing framework that guides you from hypothesis to a clear result.
Why A/B Testing Is Your Secret Weapon
Okay, so this all sounds neat, but is it worth the effort? For a small business in Dallas or a startup hustling in Austin, every marketing dollar has to pull its weight. This is where A/B testing becomes your secret weapon against wasting that precious budget.
It’s how you finally stop making decisions based on a gut feeling, your cousin’s very strong opinion, or just copying what a competitor is doing. This is your shift to choices backed by cold, hard data.
From Guesswork to Growth
Methodical testing is the most direct path to getting better results. We're talking about tangible improvements that hit your bottom line.
- Higher Conversion Rates: Turn more of your website visitors from casual browsers into actual customers, leads, or subscribers.
- Better Quality Leads: Attract people who are genuinely interested, so your sales team spends less time chasing dead ends.
- Increased Revenue: When more people convert and your leads are better, more money naturally follows. It's not rocket science; it's just smart business.
The real opportunity here is that very few companies are actually doing this well. Despite its proven power, structured A/B testing is still surprisingly rare. Studies show that a tiny fraction, just 0.2% of active websites, are using A/B testing tools. At the same time, other data reveals that A/B testing can improve conversion rates by up to 49%.
This isn't about making tiny, insignificant tweaks for the sake of it. It’s about building a fundamentally smarter online business, one proven decision at a time.
For a business owner in Katy or a nonprofit in Sugar Land, this gap between what works and what people are actually doing is a massive competitive advantage just waiting to be claimed.
A Smarter Way to Compete
A/B testing really levels the playing field. You don’t need a massive, corporate-sized budget to outsmart bigger competitors. You just need to be more deliberate and listen to what your own audience is telling you through their actions.
By consistently testing and refining your website, you create a better user experience that leads directly to more engagement. This is one of the core ideas behind our approach to conversion rate optimization strategies, where we use data to make every click count. It’s a process of continuous improvement that ensures your website isn’t just a pretty online brochure but a hard-working engine for growth.
Real-World Examples of A/B Tests in Action
Theory is one thing, but it doesn’t pay the bills. The real magic happens when you see A/B testing deliver actual results. Over the past 20+ years, we’ve run countless tests for clients all over Texas (shout-out to Bruceville-Eddy, a real place!) and beyond, helping them move from guesswork to growth.
Here are a few common scenarios we’ve tested that show the real-world difference A/B testing can make.
The Mighty Call-to-Action Button
For a service business, that main button on their homepage is everything. We worked with a client who couldn’t decide on the right words to get people to take the next step.
So, we tested it.
- Version A: "Get Your Free Quote"
- Version B: "Schedule a Consultation"
After just two weeks, "Schedule a Consultation" won by a landslide, generating 28% more qualified leads. The data showed their ideal customers weren't just price shopping; they wanted expert guidance. That one small change completely reframed the company's value and started filling their sales pipeline.
Homepage Hero Images
First impressions matter. A construction client near Arlington was torn on what to feature in their hero section. Should they show off their best work, or put a human face to their brand?
We set up a test to get a clear answer.
- Version A: A stunning, professional photo of a recently completed project.
- Version B: A friendly, authentic shot of their core team on a job site.
The team photo won. It wasn't even close. Visitors who saw the team were 40% more likely to scroll down the page and click to the "About Us" section. It built instant trust and made the company feel more approachable. Our client happiness lead, Amy, loves seeing results like this because it proves that being human is good for business.
You don't need a huge budget to find these game-changing insights. You just need a bit of curiosity and a willingness to let your customers tell you what they want.
Email Subject Lines
A/B testing isn't just for websites. It’s an incredibly powerful tool for email marketing. We helped a San Antonio nonprofit test subject lines for their annual fundraising campaign. Their original idea was straightforward, but our hypothesis was that urgency would perform better.
- Version A: "Support Our Annual Fundraiser"
- Version B: "Only 48 Hours Left to Double Your Impact"
Version B blew the original out of the water, increasing their open rate by 18% and click-throughs to the donation page by a whopping 32%. It was a simple, no-cost change that directly led to more donations. If you're curious about what makes a subject line click, check out our guide on email subject line best practices.
Perhaps the most famous example comes from Google. Back in 2009, they famously tested 41 different shades of blue for their search result links. They found one specific shade that generated an extra $200 million in annual profit. It’s a powerful reminder that even the smallest details can have a massive impact when you test them properly.

Common A/B Testing Mistakes to Avoid
Alright, A/B testing is a fantastic tool. But like any powerful tool—say, a nail gun or my dad Butch’s endless supply of opinions—it can be misused. After more than two decades helping businesses from the heart of Houston to the quirky corners of Marfa, we’ve seen all the ways a well-intentioned test can go sideways.
Think of this as my friendly warning about the most common mistakes people make. Avoiding these is the difference between getting clear, actionable data and just making a big mess.
Ending the Test Too Soon
This is, without a doubt, the number one mistake. You get excited after one version pulls ahead after a day or two and you declare a winner. Don’t do it.
You need to run your test long enough to achieve statistical significance, which is just a fancy way of saying you need to be sure the results aren’t a random fluke. We usually recommend running a test for at least one to two weeks. This helps capture different user behaviors on weekdays versus weekends. Patience is your best friend here.
Testing Too Many Things at Once
Another classic error. You decide to change the headline, the main image, the button color, and the form fields all at once. The problem? When your new version wins, you have absolutely no idea which of those changes was responsible. Was it the snappy headline or the new shade of blue? You'll never know.
A clean test changes only one variable at a time. This is the golden rule. It's the only way to know for sure what actually moved the needle.
If you want to test multiple changes at the same time, you’re getting into something called multivariate testing. It’s a far more complex process that requires a ton more traffic and is usually overkill for most small businesses and nonprofits.
Letting Your Gut Override the Data
This one stings, but it’s crucial. You were sure your witty, creative headline was going to crush it, but the boring, direct one got twice the clicks. It’s tempting to ignore the data because it doesn’t match your personal preference.
The whole point of what we do in A/B testing in marketing is to remove ego from the equation. You have to trust the numbers. Your audience is telling you exactly what they want; you just have to be willing to listen, even when it’s not what you expected.

If you’ve read this far and are thinking, "This all sounds great, but I have a business to run," you’re not alone. That's the whole reason we exist. You shouldn't have to become a data scientist just to figure out if a green button works better than a red one.
That’s where Bruce & Eddy comes in. We bake A/B testing right into what we do, so you get all the benefits without the headaches. It’s not some extra service; it’s just part of how we build things that work.

Your A/B Testing Questions Answered
I talk with folks around Houston, Austin, and my dad's old stomping grounds in Midlothian all the time who are just wrapping their heads around A/B testing. Let's tackle a few questions I hear most often.
What Can I Actually A/B Test on My Website?
The short answer? Pretty much anything a visitor can see or click on. We usually start with the heavy hitters: headlines, call-to-action buttons (the words, the color, the placement), images, forms, and sometimes the entire page layout.
- For e-commerce sites: We’ll often test product descriptions or how pricing is laid out.
- For content and SEO: We can test different blog post titles to see which one earns more clicks from a Google search.
- For service businesses: A classic test is putting a "Request a Quote" form up against a direct phone number to see which brings in more qualified leads.
The golden rule is to test just one change at a time. This is non-negotiable. It’s the only way to know for sure what caused a change in performance.
How Long Should I Run an A/B Test?
It depends, but here's the one thing I can tell you for sure: never for just a day or two. A test that short is completely useless. You have to run it long enough to get a statistically significant sample size—enough people need to see both versions to make the results trustworthy.
We recommend running any test for at least one full week, and two is even better. This smooths out the natural ups and downs in how people behave on a Tuesday afternoon versus a Saturday morning. Rushing a test is the fastest way to get bad data.
Do I Need Expensive Software to Start?
Not always. A lot of the platforms we work with, like the Wix and Squarespace sites Blake and Landon build, have some A/B testing features baked right in. Many email marketing services do, too. They’re a perfectly good place to get your feet wet.
Sure, there are powerful, pricey tools out there. But the software is never as important as the strategy behind the test. The real value comes from knowing what to test and how to make sense of the results. That’s where an experienced partner saves you time, money, and guesswork. It's our job to handle the "how" so you can focus on the results.
If your website feels like it’s held together with duct tape and hope, maybe it’s time to talk. Bruce and Eddy has been building sites that get real results since 2004, and we’d love to see how we can help you. Let's figure it out together.
