Single URL Mode: How To Grow Conversions When You Only Have One Page

If there’s only one landing page, checkout, or main product page, it’s easy to assume proper A/B testing has to wait.

Many new product users reach the same conclusion.

• “I need more pages first.”
• “I’ll test once the site is finished.”
• “I don’t want to overthink one page.”

That hesitation quietly limits growth.

High-performing stores don’t begin with dozens of variations. They start by understanding one page extremely well, then fixing what’s already holding it back.

That’s the role Single URL Mode plays.

The Simple Approach That Works

This method keeps things focused and realistic:

• Track one page, not multiple pages
• Test one element at a time, starting with headlines
• Run each test for at least two to three weeks
• Prioritize clarity first, this drives most gains
• Reduce friction next
• Polish design last
• Apply the winner
• Repeat weekly
• Let steady improvement compound over time

One page. One focused test per week. Over a year, small wins add up to very visible results.

What Single URL Mode Actually Shows

After pasting a URL into Sigmize, meaningful behavior data appears within a day.

Instead of relying on opinions, the page starts to explain itself.

Single URL Mode reveals:

• Heatmaps showing where visitors click, pause, and scroll
• Session recordings that capture real journeys through the page
• Scroll depth data showing where attention fades
• Conversion tracking tied to sales or leads, not just clicks

This makes it clear where visitors hesitate, where confusion appears, and where momentum stops. Guesswork is replaced with evidence.

For broader context, the 7 Day Homepage Optimization Guide on Sigmize pairs well with this approach.

The Framework: One Change Per Week

This testing rhythm follows a simple principle. Change one thing, measure the result, then move on.

Most early gains come from what appears above the fold. Headlines, subheadings and primary actions carry more weight than design tweaks or micro animations.

Weeks 1 And 2: Headline Testing

The headline answers a single question in the visitor’s mind. “Is this for me?”

If that answer isn’t clear, the rest of the page struggles.

Vague headlines such as “Discover premium quality” fail because they don’t help visitors orient themselves. 

A clearer option like “Modern sofas under $500 with fast delivery” removes uncertainty immediately.

Across many tests, direct and specific headlines regularly outperform vague ones by 10-20%.

A practical setup looks like this:

• Keep the current headline as the control
• Create one alternative that clearly states the offer and audience
• Split traffic evenly
• Run the test for at least two weeks to include weekday and weekend behavior
• Judge success using orders or leads, not clicks

The Homepage Testing Playbook includes additional headline patterns that consistently perform well.

Even one strong headline improvement can lift a page from around 2% conversion to roughly 2.2-2.4%.

Weeks 3 And 4: Call To Action Testing

Once the message is clear, the next step is making the action obvious.

Buttons like “Learn more” or “Submit” create hesitation because they hide the outcome. 

Visitors respond better when the action and benefit are explicit, such as “Get your free sample today”.

Common CTA tests include:

• Button text
• Button color contrast
• Button placement near the main promise

Clear CTAs often increase clicks by 10-20% and completed actions by 20% or more.

Weeks 5 And 6: Checkout Friction Testing

Checkout is where most revenue quietly disappears.

Patterns seen across many stores include:

• Around 70% of add to carts never convert
• Mobile abandonment frequently exceeds 75%
• Unexpected costs trigger exits
• Forced account creation causes drop offs

With Single URL Mode active on checkout pages, it becomes easy to see where people stop and which fields cause friction.

Three improvements often deliver the biggest gains:

1. Showing total costs earlier in the process
2. Allowing guest checkout
3. Reducing multi step forms into a simpler flow

These changes don’t require a redesign. They remove obstacles that slow decision making.

What One Page Can Be Worth

Consider a simple example:

• 5,000 monthly visits
• 2% conversion rate
• $30 average order value

That produces 100 orders and $3,000 per month.

A headline improvement of 10-20% lifts conversion to roughly 2.2-2.4%. Revenue rises to around $3,300 to $3,600.

A clearer CTA adds another 10-20%, pushing conversion toward 2.5 to 2.9 percent.

Checkout improvements that reduce friction often add 15-37% more. Conversion now sits closer to 3.5- 4.8%.

With the same traffic, monthly revenue reaches $5,250 to $7,200. 

Over a year, that’s an additional $26,000 to $65,000 driven by one page!

When Single URL Mode Is The Right Fit

This approach works especially well when:

• There’s one key page and no appetite for multiple variants yet
• An agency needs evidence before proposing a redesign
• A new offer needs validation before building a full funnel
• There’s a goal to improve one checkout or lead capture page each week

Single URL Mode And A/B Testing Together

A/B testing shows which version performs better. Single URL Mode explains how the current version behaves.

Skipping behavior analysis often leads to wasted tests. Changes get made without understanding the problem.

A reliable workflow looks like this:

1. Observe recordings and heatmaps on the live page
2. Identify where attention drops or hesitation appears
3. Turn those insights into one focused test idea
4. Run a clean split test in Sigmize

Behavior first. Experiment second.

Quick Setup In Minutes

Getting started is straightforward:

• Open the Sigmize dashboard
• Click “New experiment”
• Select Page Variation
• Fill in the basic info
• Verify the setup
• Select “Single URL Mode” & paste the key page URL
• Choose a goal
• Start the experiment

The same day, recordings and heatmaps begin appearing. Within a week, the largest opportunity usually becomes obvious.

Common Mistakes To Avoid

Several issues come up repeatedly:

• Testing too many changes at once
• Ending tests after only a few days
• Watching charts without reviewing recordings
• Failing to apply winning changes to the live page

Single URL Mode only creates value when insights turn into action.

One fix. One test. One improvement shipped.

Single URL Mode FAQs

Why Use Single URL Mode Instead Of Only A/B Testing?
Because most users don’t know what to test first. This approach reveals real behavior so tests are informed, not random.

Does This Work With WooCommerce And SureCart?
Yes. Sigmize connects with both, tying behavior to real orders and revenue.

How Long Should A Test Run?
At least two full weeks at normal traffic levels to avoid misleading results.

Is More Than One Page Required?
No. This is designed for situations where one page matters most.

What If Conversion Is Already Above 5 Percent?
Single URL Mode still helps protect performance, uncover smaller gains, and apply lessons elsewhere.

Where To Go Next

There’s almost always one page that matters more than the rest.

Leaving it untouched means leaving money behind. Watching how real visitors interact with it creates clarity, confidence, and direction.

Set up Single URL Mode on that page.
Observe behavior for a week.
Choose one headline, CTA, or checkout improvement to test next.

Clear insight beats guesswork every time!
