How to Test Hypotheses and Build an Online Business With a Website Builder

Hypothesis testing is an essential step for any business that operates online. The idea is to validate your assumptions about customer behavior, your products or your marketing strategy. One of the biggest advantages of website builders is that they let you make changes quickly and at little cost, so you can test those hypotheses.

In this article from the website builder Weblium, we look at how you can use these platforms to build and grow a business, and how to test business hypotheses with their tools.

What is hypothesis testing?

In business, hypothesis testing means checking your assumptions against real data to find out whether a particular idea or change actually improves results. In ecommerce, this can cover a wide range of areas, from customer behavior and conversion rates to pricing changes and optimizing your product catalog structure.

The role of hypotheses in building a strategy

Say you run an online store and plan to redesign your homepage. Your hypothesis might be that a new, more modern design will make visitors spend more time on the page and, as a result, lead to more purchases. But instead of overhauling the whole site and spending time on development, you can build a simple version of the page with the builder's ready-made templates and see how the changes affect user behavior.

How to formulate a hypothesis

A well-formulated hypothesis helps you define exactly what you need to test. It has three main components:

• The change you are planning. For example, changing a price, adding new categories or launching a new feature on your website.
• The expected outcome. What do you hope to achieve with this change? For example, a higher conversion rate or better engagement with your website.
• Success metrics. The metrics you will use to evaluate the result. These could be traffic, the number of conversions or average order value.

Sample hypothesis for an online store

Put all your ideas to work! Formulate hypotheses that focus on changes to your content, customer service processes or customer engagement, not just on prices or product categories.

• Hypothesis: Adding customer reviews to the website will increase the average number of orders by 10% by building shopper trust.
• How to test it: Use the website builder to add a reviews section, then track how it affects sales.
• Metric: The number of orders before and after adding product reviews.

How to quickly update your website to test new ideas

One of the biggest advantages of modern website builders is that you can make changes quickly without deep technical work. This lets you test business hypotheses in real time and adapt your website to new market conditions as they emerge.

A/B testing

A/B testing is one of the most effective methods in online business. You create two versions of the same page and send a share of your traffic to each one to see which version performs better. A/B tests are typically used to test changes in page design, content or structure.

Imagine you are launching a new product and want to see how changing the headline on your homepage affects sales. You can create two versions of the page:

Version A: The headline "Our best product of the month."

Version B: The headline "30% off our bestseller."

With a website builder, you can easily set up both versions and see which one attracts more buyers.

Changes to website structure

Changing your website structure is another popular hypothesis, focused on optimizing navigation or how products are organized. For example, you can feature new product categories more prominently to see whether that drives more clicks to those categories.

Say your online store sells electronics and you decide to feature the Smartphones category on your homepage. The hypothesis is that shoppers will be more interested in this category if they can reach it in one click from the homepage.

With a website builder, you can make this change quickly and check whether visits to the smartphones page, and ultimately purchases, go up.

Optimizing content and design

Your website's content and design have a huge impact on the user experience and on whether visitors decide to buy. Testing different versions of your content shows you which wording does the best job of motivating customers to act.

Let's say you decide to test a new design for your "Add to cart" button. Your hypothesis is that changing the button color from blue to red will make it stand out more and get more clicks. You create two versions of the page with the website builder and compare the results.

Hypotheses worth testing

Hypothesis testing helps businesses evaluate new ideas and optimization opportunities before rolling them out in full. Here are a few examples of how to do it.

Changing a product's price

Hypothesis: Lowering or raising the price of a specific product will lead to more purchases.

This is one of the most common hypotheses ecommerce businesses test. Shoppers are price-sensitive, so adjusting a price can have a significant impact on conversions.

How to do it with a website builder:

• Duplicate pages: Create several versions of the same product page with different prices. A/B testing will show you which version performs better.
• Update prices quickly: Website builders make it easy to change product prices, so you can test different pricing strategies fast.
• Track the impact: It is important to monitor changes in user behavior. You can analyze metrics such as purchase rate, average order value and total revenue.

Adding new product categories

Hypothesis: Adding a new product category to the website will increase the average time visitors spend on the site and boost sales.

Expanding your product range can help you win new customers and encourage existing ones to buy more. It is important to test whether the new categories actually interest your audience.

How to do it with a website builder:

• Add categories quickly: Creating new product categories is very easy, so you can expand your store's offering without spending much time.
• Update menus and site structure: Adding new categories may require changes to your menu structure. You can quickly update your site navigation and see whether the new categories catch visitors' attention.
• Track behavior: Once the new categories are live, use analytics to see how much time visitors spend in these sections and how often they go on to make a purchase.

Changing design and element placement

Hypothesis: Moving key page elements, such as "Buy" buttons or newsletter signup forms, will increase engagement and conversions.

Interface and design play a decisive role in how people interact with your website. Testing different versions can help you understand which approach delivers a better user experience.

How to do it with a website builder:

• Edit the overall style: You can change color palettes, fonts, spacing, element layout and more without any special technical skills.
• Change elements: You can easily add different elements and edit their size and appearance. For example, you can replace a "Buy now" button with one that links to a specific product category.
• A/B test page versions: You can show different design versions to users at the same time and compare the results.

How to track test results with analytics

Once you have made changes to your website or launched an A/B test, one of the most important steps is tracking the results. Without data analysis, you cannot evaluate whether a hypothesis worked or decide whether to make the changes permanent. There are various analytics methods and tools that will help you draw conclusions from objective data.

Why analytics matter for hypothesis testing

Analytics are the key to understanding how users interact with your website. You can change your site's design, content or functionality, but without measuring the results, any conclusions about success will be subjective. Here are a few questions analytics can help you answer:

• Did the changes affect the number of website visitors?
• Are users spending more time on your pages?
• How has your conversion rate changed?
• Did average order value go up after the price change?

To test hypotheses effectively, you need to set up your analytics tools correctly and collect the right data.

Built-in analytics in website builders

Many modern website builders offer built-in analytics that make it easy to track your website's key performance metrics. These tools let business owners without deep technical knowledge quickly collect data on:

• The number of visitors.
• Traffic sources (search engines, social media, direct traffic).
• Clicks on specific elements (for example, "Buy" buttons).
• User behavior on pages (time on page, number of page views and so on).

These built-in tools help you collect statistics without integrating third-party solutions, which is convenient for small businesses and startups that are just getting started in ecommerce.

Google Analytics integration

Google Analytics is one of the most powerful tools for tracking test results. It is a free platform that you can easily connect to your website through the builder. Google Analytics gives you in-depth insight into user behavior and accurate information on how specific changes affect your business.

How Google Analytics helps you test hypotheses

• Goal tracking, for example product purchases or newsletter signups.
• Audience segmentation (new visitors, returning customers or users from specific regions).
• Engagement metrics such as engagement rate and average engagement time (how long users actually interact with your pages).
• Traffic sources (which channels bring visitors who convert).

Using heatmaps and click analytics

One of the most effective ways to understand how users interact with your website is heatmap analysis. A heatmap is a visual representation of clicks and mouse movements on a page that shows which elements users click most often.

Tools like Hotjar make it easy to add heatmaps to your website and analyze which elements get the most attention, such as where buttons are placed on the page. They also support scroll analysis, so you can see whether users engage with elements further down the page.

Reporting and interpreting the data

The final stage of hypothesis testing is reporting and interpreting the data you have collected. It is not enough to just gather data: you need to analyze it correctly and draw well-founded conclusions.

How to build a report

• Collect the data: Include all the key metrics you tracked during the test (traffic, conversions, clicks and so on).
• Compare versions: If you ran an A/B test, compare the results for the two versions of the page and determine which one performed better.
• Draw conclusions: Decide whether the hypothesis held up and whether the changes should be made permanent.

CRM integration for in-depth analysis

For more advanced analysis, you can integrate your website with a customer relationship management (CRM) system. This lets you track how your hypotheses affect customer behavior across the entire customer lifecycle. For example, changes to your website's interface may lead to more callback requests or product questions. Some website builders offer a built-in CRM.

Conclusion

Hypothesis testing is a key process for building a successful online business, and using a website builder makes it much simpler and faster. Thanks to the flexibility of these platforms, you can make changes quickly, test new ideas and adapt your website to market needs.

Analytics, integrations with performance tracking tools and the ability to make changes fast let you not only validate your hypotheses but also keep refining your strategy for the best possible results.
