19 A/B Tests You Should Run on Your Website

This is curated content from the best of the best blogs around IMHO, indispersed with a few of my own.


Summary. A/B Testing is a process to which you can test a number of variations to see which performs better. This marketing strategy is a useful way of understanding your users so that you can put the results into action and increase your conversion rates.

This article by Neil Patel explains which A/B tests you can run on your website.

Conversion rate optimization isn’t an easy game to play, especially if you’re the new kid on the block. One of the best ways to improve CRO is by A/B testing features on your website.

The real challenge with CRO is in knowing how to start and what to test. This post covers the latter.

There is one thing to keep in mind: testing every random aspect of your website can be counter-productive. You can blow time and money on software, workers, and consultants, testing things that won’t increase your website revenue enough to justify the tests.

So before you dive in, make sure to think about what your goals are.

Then, take a look at the following tests and see which ones make sense for your specific business. If so, ahead and run it. If not, try another one.

A/B Test: Typography

Typography is proven to affect conversions in a major way, but casually testing each Google font won’t get you anywhere. There are a few aspects of typography you need to test first before getting specific with typefaces.

1. Serif vs. Sans Serif

Serif typefaces are accented with various widths for each line in a character and contain flourishes (for example, Times New Roman). Sans serif typefaces are just the opposite, plain with a consistent width (like Arial).

I suggest using sans serif, but interestingly, Georgia (a serif typeface) is by far the most popular typeface on the web.

Try both varieties to see which works best for your website.

As per a WDD infographic, sans serifs are best for the web, and serifs for print.

2. Colors

For your blog, your long-form copy, and most of the text on your website, always go with black (dark) text on a white (light) background. It’s a traditional color scheme our eyes are accustomed to.

For your calls to action and other smaller, more impactful text elements, however, test each of the basic eight colors (or whatever colors fit with your design). Always remember this principle: what stands out gets clicked.

3. Font Size

Tahoma tends to be the most legible at 10 px, Verdana and Courier at 12, and Arial at 14 px.

Whatever typeface you choose, make sure that you test the differences in user engagement and click-throughs according to the size of the font. These days, as mobile traffic increases, larger tends to work better — but not always.

4. Typefaces

Finally, we get to the most tedious typography test – typefaces. Take this one with a grain of salt. Don’t test each of the 700+ Google fonts available. Doing so would be very counter-productive. Only test a few of the major ones that harmonize with your design.

When testing these, you’ll also want to go with an A/B/C/D/etc. test. This will let you test multiple typefaces at a time.

A/B Test: Calls to Action

Your call to action (CTA) is the most influential element on your landing page. Period.

As such, it requires a substantial amount of experimentation. Here are a few of the main call to action “ingredients” you need to test.

5. Position

Too often, web designers put the call to action button in the middle of the landing page above the fold, and just leave it there, because it’s what you’re “supposed” to do.

But did you know that locating your CTA below the fold could increase your conversion rate by 304 percent? Don’t take anything for granted: test above the fold, below the fold, in the middle/left/right of the page, and relationship to text elements.

6. Color

Color is a biggie in most CRO tests. Many have read this post on HubSpot about how a red CTA button beat a green one with a 21 percent increase in conversions. But a similar test in the Content Verve post (linked to in test #5 above) detailed how a green “add to cart” button got 35.81 percent more sales for an e-commerce store than a blue one.

A contrasting color that is distinct and stands out from the other elements on the page seems to work best. Experiment to see what works for your CTA. Don’t rely on other people’s tests to pick a color.

7. Text

As the most crucial copy on your landing page, your call-to-action button text needs to be tested heavily. Try out various lengths, pronouns, power words, and action verbs.

Back when the 2007 U.S. election campaigns were in progress, Obama raised an extra $60 million just by changing his CTA button text from “Sign Up” to “Learn More.”

Yes, that’s a 60 million dollar test.

Don’t miss out on those potential returns.

A/B Test: Pricing Schemes

This section encompasses more than just what price you set for your product/software. You also have to think about free trials and money back guarantees.

8. Freemium vs. Free Trial vs. Money Back Guarantees

To allow prospects to try products (and yes, product demos are important), vendors usually offer at least one of three models: a very basic freemium product with limited features that can be used forever, a time-sensitive free trial that allows users to experience all the bells and whistles, and a time-sensitive money back guarantee.

Changing from a freemium software model to a 14-day free trial increased Acuity Scheduling’s paid signups by over 268 percent. Try each model to see which works best for your business.

9. Free Trial Length

If a time-sensitive free trial is what works for your website, then how long should that free trial be? 7 days? 14, 21, 30? Test it!

This post on Sixteen Ventures mentions how shortening a 30-day free trial to 14 days proved to be a profitable choice for a SaaS company.

Depending on your particular niche, the results may vary. As you can see below, for Crazy Egg, a 14-day free trial is the sweet spot.

10. Pricing Each Plan

Don’t forget to experiment with your pricing plans. Not only should you try out different prices for plans (should your price be $x9 or $x7?), but you also should play around with the features of each to make your higher-ticket plans convert better.

Oh, and don’t forget: decoy pricing models are the bomb. By offering a much higher price before a mid-tier option, users are likely to spend more without realizing why.

A/B Test: Landing Page Copywriting

The art of persuasion through words on a page – copywriting – is another essential part of a landing page. Great copywriting is never great on the very first draft; it requires careful testing to ensure maximum impact.

11. Short-Form Copy vs. Long-Form Copy

From a philosophical point of view, short-form copy should work better than its longer rival. After all, humans have a shorter attention span than goldfish, right?

Unfortunately, that isn’t a set-in-stone rule. For example, testing on Crazy Egg found that long-form copy produced 7.6 percent more leads (and better-quality ones as well). On the other side of the spectrum, a Scandinavian gym chain got 11 percent more conversions with shorter copy.

The takeaway? TEST to discover what works for your business.

12. Video vs. Text Sales Pages

Video copy is both difficult and expensive to create; hence, the general preference for text-based copywriting. But could you be missing out on potential conversions by failing to test video copy? Maybe so.

Depending on the size and capital of your business, you’ll have to decide whether a video sales page is worth it (and don’t forget text and video combinations).

13. Actual Text

As with typefaces, testing hundreds of different versions of your text-based copy, each with only a small change from its predecessor, can be a fruitless waste of time and money.

So, while you should continually edit and experiment with your copy, remember to look at the bigger picture. Don’t get hung up on every other word.

General A/B Tests for Your Website

The following are various A/B tests that don’t fit in any of the above categories. They fall under sales funnels, website design/structure, and more.

14. Number of Columns

Multiple-column landing pages definitely look a whole lot cooler than those with single columns.

But in CRO, coolness doesn’t count.

In fact, a SaaS company increased its conversion rate by 680.6 percent when it changed its two-column pricing page to a single-column page.

15. Background Images and Patterns

Your landing page background (a solid color, pattern, or image) has a very consequential subliminal effect on your readers. If you haven’t tested different background varieties yet, you’re leaving money on the table.

Spreadshirt tested their homepage images and increased clicks by 606 percent and sales by 11 percent.

16. Navigation Links

Your navigational menu’s presentation affects how and if you can get visitors to your money pages (your pricing page, contact form, etc.).

Test the number of links, the color of the menu, its position, etc.

17. Link Color

Trying to get visitors to click links from your blog post to your money page? Test the link color.

The presentation of your internal links isn’t something that most people associate with CRO right off the bat. But when you think about it, internal link color really can have a huge impact on the number of visitors that get into your sales funnel.

Take Beamax, for example, which increased link CTR by 53.13 percent by changing their link color to red from the standard blue.

18. Contact Form Fields

If your objective is to get contact/quote requests from your website, then the format of your contact form is critical to your conversion rate.

Test the number of fields (bare minimum is usually best) and the types of fields (checkbox vs. drop-down) to elicit more form submissions.

We changed the number of contact form fields from 4 to 3 for a 26% boost in conversions.

19. Number of Steps in Your Checkout Process

Case study after case study has proven that single-step checkouts will almost always convert significantly better than multi-page checkouts. If you’ve never considered a single-step checkout before, it’s time to test one.

Final Thoughts on A/B Testing Your Website

Sometimes it’s not the most obvious A/B tests that drive the most growth. Instead, it can be the unconventional tests, the ones you would have never thought would make an impact, that prove to be the most valuable. Other times, doing less can actually drive more conversions than constantly testing.

The A/B tests above should serve as a starting point. Once you see what changes impact conversions, you’ll have a better understanding of what drives your audience.
