Understand the purpose of Landing Page Testing

What is Optimization All About?

The purpose of any landing page is to reform possibilities. Effective landing pages convert well because the content of the landing page matches the content of the ad that brought the customer to the page.

But if you have a poor-performing landing page, it’s very difficult to nail down where the disconnect lies. With so many elements to test, it can seem overwhelming to try and figure out how to optimize your pages.

Developing a high-converting landing page requires a lot of work, but is one of the best ways to see a positive ROI on your marketing campaigns. If you are running any campaigns with a landing page and haven’t run a test, you are leaving money on the table. By the end of this training, you’ll know how to run a split test on your landing pages and discover what’s actually working and what you need to fix to drive more ROI.

Great landing page optimization starts with asking the right questions and setting up experiments in a methodical way.

In this playbook, we’ll go over the anatomy of a great landing page test, and how you can build out your tests to help optimize your landing pages to convert more prospects.

Know-How and What to Test

Know What A Great Test Entails

All tests are not created equal! You need to make sure that the landing page tests you are running are good quality tests. There are a few considerations to keep in mind when selecting and qualifying your tests.

  1. Should you even test your page?
  2. What type of test are you running?
  3. How much of a difference will your test make?
  4. Can you implement the tested changes to your landing page?
  5. Does the test line up with your KPI’s?
  6. What is your hypothesis?

Let’s review these considerations, and then determine the order in which you want to run your different tests. 

Should You Even Test Your Page?

Simply put, not all pages can (or should) be tested and anyone who says otherwise is doing you a severe disservice. Sometimes some pages just need to be fixed. For example, if you were running Google PPC traffic to a landing page and were missing compliance elements – then you wouldn’t test the addition of these elements, you’d just add them! 

Before you start building up tests, make sure that you are testing a page that should be tested and testing elements that will make a difference. You should start testing when you’ve arrived at a crossroad and there isn’t a clear way to proceed.

Here’s an example:

landing Page Optimization contact us

There is a page with a broken lead generation form – do you test it? No! fix the form and move on. Here’s an example of a local dentist who was wondering why his contact page wasn’t converting. The form is…

  • Awkward,
  • below the fold,
  • and has a ‘reset’ button.

Should he test? No! Make the necessary changes on this broken page and test something worthwhile! 

Numbers are also crucial when deciding whether to test. If you don’t get enough traffic, you won’t be able to run a conclusive split test. 

Is It an Offer or Structure Test?

The first step to running a test is to decide whether you are testing your offer or the page structure. 

Offer Tests focus on optimizing the offer you are giving and how it is portrayed to the prospect. Some questions you may ask about your offer could include:

  • Are you providing a checklist or a video? 
  • If they are purchasing something, is the price a fair representation of the goods offered? 
  • Is your offer clearly explained?
  • If you’re offering a product, is the product shown?

You should never assume that the offer is good just because that’s the offer you’ve always used. No number of structural tweaks can make a bad offer convert! 

Structural Tests focus on optimizing the anatomy of the landing page. 

These types of tests experiment with things like:

  • new copy, 
  • images, 
  • page layouts

We’ll discuss more of these elements in detail later.

The best practice is to make sure you optimize your offer before anything else. 

* Action Item: Decide if you want to run an offer test or a structural test. *

Will Your Test Make a Difference?

Consider the probability that the test you will run will provide a dramatic increase in the desired behavior (opt-ins, purchases, clicks, etc.) 

Tests with a high lift percentage (the percent difference you think your test will have on your results) require a smaller sample size. So, on top of having a great immediate impact on your conversions, tests with a high lift potential can also be completed faster than tests with smaller gains. 

Can Your Test Be Implemented?

There are 2 major considerations to keep in mind when deciding what to optimize first:

1. How hard will it be to get the test going?

Running the test requires your testing tech tool to be placed on all measured pages (not just the test page itself). Every test will require these basics:

  •   Code on your site
  •   Goal Links
  •   Test Assets, e.g., copy, Images, etc.…

The inability to produce or implement test assets can lead to delays in your test launch. The more complex the assets or changes to the website, the longer the test will take. 

2. How hard will it be to get the winning version live?

If you run a test but will never have the ability to make the winning variation live — don’t run the test. 

Most landing page tests are either smaller scale tweaks or larger radical redesigns. The former isn’t a major change for developers, but the latter is likely to require a split URL test, which is more work for you and your developer.

*Action Item: Make sure you have the time and resources available to run the test, and also implement the results. *

Does the Test Align with Your KPI Goals?

The more business-oriented your KPIs, the higher priority the test. Tests that focus on vanity metrics like clicks or Facebook Likes, are not going to directly impact your business goals. As marketers we love looking at all of our fun marketing metrics, but at the end of the day you are usually most concerned with 2 things: Revenue and Costs.

Higher priority KPIs are the KPIs that are directly connected to revenue and costs. These would include:

  • revenue per visitor
  • earnings per click
  • average order value
  • purchases

*Action Item: Determine what KPI’s matter most to you, and if your test aligns with those KPI’s *

Think Through Your Hypothesis

A test without a hypothesis is just a guess.

You don’t want to test a new variation because ‘You think it will work’ or because ‘someone else is doing it’. You want to optimize the user experience, and the only way to do that is by looking at the data. 

You need both qualitative and quantitative insights to create a solid hypothesis. Look at raw conversions, the conversion rate, and bounce rate. These numbers will let you know if there is a problem with your current landing page. 

Now the fun part, looking at the qualitative data. Make sure to put your landing page in context. First, start by asking yourself these questions:

  • Is there a sense of continuity from the initial ad click and the landing page? 
  • Do they have similar images, color scheme, and the identical offer? 

If all of these things are in order there are other tools you can use to grab better qualitative insights. 

Here are a few options you can use to get more qualitative data:

  • tracking tools like Crazy Egg or Hotjar to get heatmap, scroll maps, and other click reports. These reports help you learn how your customer is interacting (or possibly glancing over) elements of your site.
  • surveys
  • personas
  • user testing
  • customer service inquiries
  • sales inquiries

Remember, qualitative data is crucial for hypothesis construction, so take the time to gather as much information as you can get. 

*Action Item: Take note of the qualitative data you need and make a plan for how you will gather the data *

Once you have enough data, you can create your hypothesis. 

Every hypothesis you create needs to follow this format:

We believe that changing A for visitors B will cause C to happen. 

If the test doesn’t meet the above terms then you shouldn’t run the test

*Action Item: After looking over your qualitative data, write your hypothesis. * 

But what if you aren’t sure what elements to look at first? Let’s go over some test elements you should consider looking into

Prioritize Your Tests

When you are determining what tests you should run, it’s helpful to look at all the previous factors at once. This Test Priority Excel Document is a great resource to help you rank all the different tests.

Test These Elements If You’re Not Sure Where to Start

Different Elements You Can Test

This section is about coming up with potential ideas for your next landing page test. These elements have been a major factor for conversions at DigitalMarketer, but make sure these tests work for you before you go running 50 of them (check with your qualitative data!).

Every audience is different, and while one element might work well for one website or web page, it likely may not work for another.

If you want to make sure your landing page actually converts, here are 5 elements you should look at testing:

  • Offer (always first!)
  • Call to action
  • Proof
  • Trust
  • Images

In this article we are going to focus on structure tests, and cover offers testing in another article. When testing these structural elements, you are trying to discover the best way to convey these elements to your customers. Now let’s test some elements.

Testing Call To Action

The call-to-action is one of the most vital parts of your desired landing page. It needs to stand out and have an actionable message. The first thing you should check is that people actually see your call to action. If they don’t know where to click, they won’t click! 

You’ll know that your CTA is getting attention based on the heatmap for your page. It should look something like this: 

If your CTA isn’t getting these kinds of clicks, you need to make it more apparent. You can accomplish this a few different ways:

  1. Change the location of the button so that it’s in a prominent place above the fold, and also scattered throughout (if it’s a longer landing page)
  2. Change the color so it is more contrasting against the background
  3. If you’re using ghost buttons, change to regular colored buttons

If your CTA is clear and visible, your issue could be the copy. Make sure it is action-oriented and descriptive. Short and obscure CTAs won’t likely get the job done. Check out this example from ContentVerve, where the team tried to improve an already descriptive CTA:

Notice how a small tweak on this CTA saw such an impressive lift. When you make small changes on important elements, you are bound to see some conversion shifts.

What’s Next?

Understand the purpose of Landing Page TestingKnow How and What to TestTest These Elements If You’re Not Sure Where to Start

Test Your Headline

Sometimes a headline can damage or break your landing page! I know a lot of copywriters will like to get cutesy with their headlines but do yourself a favor – don’t!

The best headline is often simply a descriptive one that meets your visitor’s needs.

There are a few ways to gauge whether your headline is going to convert:

1) Evaluate your headline to see if it addresses these 2 crucial questions:

  1. What is it?
  2. What does it do for me?

If your headline doesn’t address both of these questions clearly and effectively, you can be sure that it is depressing your conversions.

2) Evaluate your customer’s quick takeaway. 

Typically, when given a short timeframe to take in information, people look at the headlines and images. You can set up a Five-second test to see what information viewers take away from your page, and what they remember. This will help you see if customer’s first impressions are in line with what you want them to take away. 

Test Your Images

We’ve heard the saying “a picture is worth a thousand words”, and in the case of your landing page this couldn’t be truer! Images command a lot of attention on your landing page, so pay close attention to them. 

When using imagery on landing pages, you want to make sure your images do the following:

  • showcase your product/service in a clear, understandable way. 
  • Over-exaggerate your product/service (or you could be hit with some pretty harsh compliance issues from paid traffic providers). 
  • compliments the page copy and layout, rather than overpower everything. It’s easy for images to cause visual confusion and actually distract people from converting. 

Notice how changing the image of the slide to have it face the copy increases views of that copy? This is because people tend to look where others are looking (even if it is an image and not a real person).  

If you think your image is hurting conversions, ask these 3 questions: 

  • Am I using stock photos?
  • Does my image break the eye flow?
  • Does my image break the visual consistency from the ad to the landing page?

If you say yes to any of these questions, an imaging test is in your future!

Test Your Trust Indicators

If you want action on your landing page, your site visitors need to trust you! One of the best ways to develop trust is by using multiple forms of trust indicators.

Trust indicators include:

Privacy Policies: The privacy policy is absolutely crucial for your landing page. On top of building trust with your prospects, a privacy policy is also a necessary addition for Google (and other paid traffic sources) compliance.

Security Seals: Security seals are another trust indicator that can help increase conversions. When selecting security seals, ensure that you are using seals people recognize and are appropriate to the situation. 

Guarantees:  Money-back guarantees, shipping guarantees, etc. are helpful to include so long as they align with what the CTA is. 

Testimonials: Testimonials matter because people want to know other people have used this product/service and have had success. Using one or 2 testimonials will help When you use testimonials on your landing pages use the following:

  1. A picture of the person giving the testimonial
  2. A brief quote
  3. The name, company, and title
  4. Consider testing some different trust elements on your page. 

Test Your Copy

The copy is a crucial element on your landing page.

The amount of copy on your landing page is usually directly correlated to the price and complexity of your offer. 

For lead generation landing pages (often called squeeze pages) and lower ticket items you may only need…

  • headline,
  • subhead,
  • hero shot (image)
  • bullets,
  • CTA,
  • trust indicator. 

However, higher tickets, more complex offers will likely need more copy including More Product Images, trust indicators and guarantees.

We discussed some copy elements worth testing in previous sections, but here are 5 copy elements to test on your landing Page:

  • Headlines
  • Sub Headlines
  • Bullet Points
  • Photo Captions
  • CTAs

As a final note, if you are using longer form sales letters and prose to push your offer make your content skimmable! Write in small sentences, shorter paragraphs, and bold the key points! A “skimmer” (which is most of everyone online) won’t read big blocks of text.  Keep it readable.  

Test Your Videos

Videos are powerful tools to help communicate your offer quickly, effectively, and in an interesting way. Here are a few factors you can test with your videos to help improve conversions. 

Video Length: video length is directly connected to the price and complexity of your offer. Longer more descriptive videos are not appropriate for lead generation or small-ticket items.

Voice Actor: Test out different actors. If you have the resources to get a professional voice actor to narrate your video, make sure to get a diverse group of actors to test from. Things like accents, gender, mannerisms, and more can all have an effect on how well your audience relates to the actor, and thus how well they connect with the offer. 

CTA Delay: Sometimes you want your visitor to actually listen to what you’re saying and not distract them with your call to action right away. If you are going to try out CTA delays, make sure that your video gives audio cues to the prospect. 

Adding in ‘Click that button below’ and having it appear at that moment is a tactic we use here at DM and it has worked well for us.

No call to action is displayed (image left) until the sales arguments have been made — at which point the buy button is “popped” (image right.) 

Test Your Videos

Remember, just because this tactic has worked well for us doesn’t mean it will for you. Your visitors might be impatient and want to click through right away. Test this!

Auto-Play vs. Click to Play: This is another great test that will likely be impacted by your audience. Corporate B2B audiences tend to bounce on auto-play videos, but a consumer audience will actually see a conversion boost. This is an easy test to set up with your video player, and very worthwhile. 

Set Up Your Test

Decide on a Testing Software

At this point, you should have a good idea what test you want to run. Now it’s time to set up your test inside your testing software. This process will look different depending on which software you have. Here are some different testing software’s you could try out:

*Action Item: Decide what testing software would work best for you *

Remember This When Setting Up Tests

Every test needs a starting point and a stopping point. If you start a test with no clear end in sight or an end that is months away, you’re doing it wrong! This is why low traffic sites really can’t run a true split test, they just don’t have the traffic to get usable data in a reasonable timeframe. 

What is a flexible time span? I generally say no more than a 6 month period (and that’s stretching it). Ideally, you’d like to cover at least one business (two is optimal) cycle before calling a test. For consumer brands a business cycle is around 7 days. 

We Recommend you schedule your testes in advance. This helps for 2 reasons:

  1. It makes sure you don’t call a test too soon. Testing techs (like Visual Website Optimizer or VWO) love to tell us something is statistically significant even though the test has only run for a few hours or days. Since 25% of marketers report that they call a test as soon as the tech indicates, simply scheduling a test would immediately remedy this bad testing practice.
  2. It will help your testing activities since you’ll know whether you can actually run a test then! If you can’t get enough data within 6 weeks, you might want to find another page to test on.

When scheduling a test there are a few major factors that will impact test timing:

Number of Conversions

If you aren’t getting between 100-200 converting actions per each variation, your test won’t provide incredibly useful data. If you think this is high, it is for a reason, you need a large enough data set to make business decisions. 

If you pull from a small data set there is a higher chance for error, specifically a false positive. A false positive is when you report a change when there actually isn’t one. 

If you do not get at least 100 conversions per variation, but still want to test – tread lightly!

Number of Variations

If you have a low traffic, don’t run multiple variations. For every variation you add, your traffic need grows exponentially! 

It is important to keep your test simple at the beginning, get familiar with the practice, and then go for more complex tests (if you have the traffic).

Confidence Level

The confidence level tells you whether the change you are seeing is happening due to the changes you made or other variant noise. In other words, the confidence level tells you at what percentage you can be sure there was an actual change. 

95% confidence is the industry standard. This means that there is a 5% chance the reported change is actually due to randomness. The industry is comfortable with this 5% threshold, which actually means that 1/20 tests are due to randomness. If you see a test result that is too good (or bad) to be true, there is a chance it actually is, and you need to retest. 

The higher your confidence level, the more data you need. Conversely the lower the confidence, the less data you need. If you are traffic-challenged, you could go for a lower confidence rate, say 90%. If you do this be sure to note that the test results are a higher risk. 

Amount Of Traffic

Where conversions dictate the length of your test and traffic dictates the number of conversions, it just stands to reason that traffic is a factor. Your traffic will help you estimate just how many days you need to run your test. 

Lift Percentage

The actual lift between each variation will also dictate the amount of time it takes to run a test. I know it’s hard to estimate the expected lift and I encourage you to use industry conversion rate data as a benchmark and estimate accordingly. 

Also, always use conservative estimates to ensure that you are giving your test enough time to gather the needed amount of data. 

The lift percentage is what actually causes split testing techs to call tests earlier than they should! There is generally a lot of volatility early on in a testing period. Since the lift percentage is just so different, a testing technology might believe the test is significant despite the numbers not normalizing. 

In the end, you really just need to know the basics numbers to plug into an easy-to-use testing duration calculator. I’d recommend using VWO’s duration calculator because it’s simple! Just plug in that information and look at the output.

*Action Item: Use a duration calculator to determine your test length *

When you get this output, you have one final step Round up the number of days to complete the week. If your calculator says it will take 9 days to get the data, round up to 14. Your optimization calendar and test data will thank you! 

*Action Item: When you have your timeline – toss it into your calendar and run that test! *

You’ve Run a Test, Now What?

Compile Your Results

Once your test runs its course it’s time to compile your results. 

We like to collect the same core information from every test we run. This information includes:

  • Test name
  • Page URL
  • Test dates
  • Metric measured
  • Screenshots of your different versions
  • Page results for both versions (Traffic, Conversions, Conversion Rate, Relative Lift) 
  • An analysis summary
  • Any other observations
  • Next Steps

This information should be documented for every test you run, regardless of the outcome!  

Your next steps will depend on how your test went:

For winning tests: A Winning test will show that the metrics increased at a statistically significant amount for the test page. Your usual next step is to make the changes you tested live. You also may want to run follow up tests for anything you noted in the “Other Observations” section.

For failed tests: A failed test will show that the control page (the one with no change) has higher, statistically significant increases in the metrics tracked. In this case, you may not want to put the changes you tested live, but you still might have follow-up tests to run based on the information you learned from this test. Failed tests are still incredibly helpful in gathering information about your page’s performance. 

For flatlined tests: A flatlined test will have no statistically significant results to show. You’ll know it’s time to pull this test when your data starts to flatline out for all the metrics your tracking. When this happens, your best bet is to stop the test, so you aren’t wasting time and possibly money on the test. 

And with that, you are ready to start running your own landing page split tests!
