Most small business website changes are made by gut feeling. Someone on the team says the button should be green. The owner thinks the headline needs to “pop” more. The designer wants to try a full-screen hero image. So you make the change, cross your fingers, and wait to see if leads go up or down.
That’s not optimization. That’s gambling.
A/B testing replaces opinions with data. You show version A to half your visitors and version B to the other half. Whoever converts more wins. No arguing, no politics, no guessing.
HubSpot’s research shows that A/B testing is the most used method for increasing conversions among companies that actively optimize their websites. Yet less than 20% of small businesses run any form of systematic testing at all. That gap is an opportunity.
You don’t need a $500/month enterprise platform to run meaningful tests. Tools like Google Optimize’s replacement options, VWO, and Convert let you run split tests on a small business budget. Some website platforms have testing built in.
Here are the 9 tests worth running first.
1. Your Hero Headline
The headline on your homepage is the highest-leverage element on your entire site. It’s the first thing most visitors read. It determines in about three seconds whether they think you’re for them.
Most small business headlines fail because they describe the company instead of the customer’s outcome. “Full-Service Digital Marketing Agency” tells me what you are. “Get 30% More Leads From Your Existing Website Traffic” tells me what I get.
For your A/B test, keep everything identical except the headline. Run one version that leads with what you do (your current headline, probably) against one version that leads with the primary benefit you deliver. Use your most common customer outcome as the benefit version.
Conversion XL’s research consistently shows that benefit-focused headlines outperform feature or identity-focused ones. The lift can be anywhere from 15% to 90% depending on how bad the original was.
Let the test run until you have at least 100 conversions in each variation, or your testing tool shows 95% statistical significance. Don’t call it early.
2. Your Primary CTA Button Copy
“Submit.” “Click Here.” “Learn More.” These are the three worst button labels in the history of the internet.
Button copy is one of the fastest and easiest A/B tests to run, and the results are often dramatic. A study by Unbounce found that changing button text from first person (“Get My Free Report”) versus second person (“Get Your Free Report”) produced a 90% lift in clicks in one test.
The principle: your CTA button should describe what happens next from the user’s perspective, not your company’s. “Schedule Your Free Consultation” beats “Submit.” “Show Me the Pricing” beats “View Plans.” “Start My Free Trial” beats “Sign Up.”
Test your most important button first. That’s usually the one above the fold on your homepage or the primary CTA on your highest-traffic landing page. Swap the vague label for something specific and action-oriented. Track clicks and downstream conversions — not just clicks.
3. Form Length vs. Conversion Rate
Every additional form field you add costs you leads. This is not a theory. It’s well-documented across thousands of tests.
Hubspot’s analysis found that forms with three fields convert at higher rates than forms with more. A study by ImageScape found a 160% increase in conversions when they reduced form fields from 11 to four.
But here’s the problem: sales teams want more data. They want job title, company size, phone number, annual budget. So most contact forms end up bloated.
Your test: take your primary lead form and create a stripped version with only the minimum fields you need to follow up. Usually that’s name, email, and one qualifying question at most. Run it against your current form. The shorter version will almost certainly win on volume. The question you’re actually testing is whether the quality of leads from the shorter form is good enough to justify the volume increase.
Track what happens downstream. If shorter form leads close at the same rate, kill the extra fields permanently.
4. Social Proof Placement and Format
You probably have testimonials somewhere on your site. The question is whether they’re actually doing any work.
Most small business testimonials are buried on a dedicated “Testimonials” page that nobody visits, or they’re generic three-star quotes that don’t mention a specific outcome. Neither format converts well.
Nielsen’s research found that 88% of consumers trust online reviews as much as personal recommendations. The conversion impact of well-placed social proof is significant, but placement matters enormously.
Test adding a short, specific testimonial (one with a real name, a real outcome, and ideally a photo) directly below your primary CTA — not on a separate page, not in a carousel. Put it right where the conversion decision happens.
Compare that placement against your current setup. Specific outcomes beat vague praise. “We closed three new enterprise accounts in our first month working with them” outperforms “Great service, highly recommend.” Test the format too: a short quote with a photo typically outperforms a text-only wall of testimonials.
5. Pricing Page Display Format
If you have a pricing page, it may be the single most important page on your site after your homepage. Most small businesses either hide their pricing entirely (a mistake for most service businesses), display a wall of text, or use a three-tier table without thinking about how the options are framed.
Pricing psychology has been well-studied. MIT and Carnegie Mellon research has shown that how you frame price options changes which ones people choose — and whether they buy at all.
For your A/B test, try two variations:
Variation A: Highlight your middle plan as “Most Popular.” This is the classic anchoring play. The expensive plan makes the middle one feel reasonable. The cheap plan makes the middle one feel like a smart choice.
Variation B: Lead with your most popular plan first (top of the page or left column) and remove the anchor pricing entirely.
Track which layout drives more conversions at the plan level you care about most. Even a small lift on pricing page conversions has an outsized revenue impact because the visitors who reach that page are already warm.
6. Video vs. No Video on Your Homepage
Adding a video to your homepage feels like a big move. It also has the biggest potential payoff of almost any homepage change you can make.
Wyzowl’s 2024 Video Marketing Report found that 84% of people say a video convinced them to buy a product or service. Unbounce has documented conversion lifts of 80% or more from adding an explainer video to a landing page.
The catch: it has to be the right video. A 90-second explainer that clearly answers “what do you do, who is it for, and what happens when I hire you” is powerful. A two-minute corporate overview with stock footage and inspirational music is not.
If you already have a video, test it above the fold vs. below. Test autoplay (muted) vs. click-to-play. Test including a transcript.
If you don’t have a video yet, this is worth making. Even a simple founder video — someone on camera for 60 seconds explaining what you do and why customers hire you — outperforms no video in most tests.
7. Mobile Navigation and CTA Accessibility
Here’s a test most small businesses skip entirely: mobile-specific layout optimization.
Statcounter data from 2025 shows that mobile accounts for over 58% of global web traffic. Your conversion rate on mobile is almost certainly lower than desktop, and one of the biggest culprits is how hard it is to take action on a mobile screen.
Test whether your primary CTA button is visible on mobile without scrolling. Most homepages have a hero section that pushes the CTA below the fold on smaller screens. Test a version where the CTA is the very first thing a mobile user sees, or test adding a sticky “Call Now” or “Get a Quote” button that follows them down the page.
Google’s research has found that 53% of mobile visitors leave a page that takes more than three seconds to load. Before you optimize layout, confirm your mobile load time is under three seconds using PageSpeed Insights.
Once speed is handled, run the CTA visibility test. For service businesses with local customers, a sticky click-to-call button alone can double mobile leads.
8. Trust Indicators Near Your Contact Form
Your contact form exists to capture leads. But before someone fills it out, they need to believe two things: that you’re legitimate, and that contacting you is safe.
Most small business contact forms have none of the trust signals that address these concerns. They just have the fields and a submit button, maybe next to a stock photo of a handshake.
Test adding the following trust elements directly adjacent to your form — not below it, not on a separate page:
- A short privacy statement: “We don’t sell your information and won’t spam you.”
- Your phone number and physical address (if you have one)
- A brief response time commitment: “We respond within one business day.”
- One client logo or named testimonial from someone in a similar industry
VWO’s conversion research shows that trust indicators near forms consistently increase submission rates, particularly on first-visit traffic. The phone number alone often matters. People want to know a real person is on the other end.
Test your current form against a version with these trust elements added. Keep everything else identical.
9. Exit Intent Popup vs. None
This one is controversial. Popups are annoying when done wrong and genuinely useful when done right.
Exit intent popups trigger when a user’s cursor moves toward the browser’s close button or address bar — a signal they’re about to leave. At that moment, you have one last chance to offer them something.
OptiMonk reports that exit intent popups convert at 10-15% on average for well-targeted offers. For visitors who were otherwise going to leave with nothing, that’s recaptured opportunity you’d otherwise have lost completely.
What to offer:
- A free resource (checklist, template, guide) in exchange for an email
- A limited-time discount if you run e-commerce
- A “book a free 15-minute call” offer for service businesses
Test having an exit intent popup (using a tool like Sumo or Wisepops) against no popup at all. Measure both the popup conversion rate and whether it negatively affects overall site behavior (bounce rate, time on site). A good exit popup adds leads without hurting the experience for visitors who stay.
Start With One Test, Not Nine
The mistake most businesses make when they discover A/B testing is trying to test everything at once. Run one test at a time. Wait for statistical significance. Make the change permanent if the winner is clear. Move to the next test.
That discipline compounds fast. One 15% conversion lift on your contact form, another 20% lift from better button copy, another 10% lift from trust signals — suddenly your site is converting twice as well as it was six months ago, and you have data to explain exactly why.
If you’re not sure where to start, test your hero headline first. It’s the highest-traffic element on your site. A win there affects every visitor, not just the ones who make it to your contact page.
