CRO (Conversion Rate Optimization) A/B Test Samples

1. Popup Banners AB Test

4 Banner types were tested to see which performs best on a Sweet Leilani. Here are the 4 types:

Regular Popup

Full Page:

Slide In:

Results:

The popup banner is the best one from the group. It had an 8% conversion rate on email subscriptions plus 5 orders worth $521.

The full screen popup came in 2nd place with 8% conversion rate on email subscriptions but only 1 order went through for $123.

The slide in came in 3rd place and the banner popup came in 4th place.

The regular size popup seems to be the overall winner of this AB test. It is set to popup after 15 seconds or if the user tries to leave the site. 

2. CTA Text AB Test

This is an A/B test Unbounce did. They claim that changing this one word boosted CTA by 90%. How to Design Call to Action Buttons that Convert.

3. Button Color Change AB Test

Before and after button test yields 58.8% boost in click through. This pink and green button stands out like a sore thumb to an audience targeting women over 45 years of age. Other button colors were tested too but none of them performed this well. Pink is usually a woman's flavor. The green text color is also interesting and makes it stand out in the page more.

 

4. Why CRO Conversion Projects Are A Profitable Investment

Why Every Website Needs An A/B Test

Conversions boost anywhere from 20% to 2000% as I have seen before. All this costs very little per A/B test depending on what the buyer pays but the profits go on forever without any risk. For example, if a $10,000 per month website boosts conversion by just 30%, that is $3000 more per month without risk or $36,000 more per year of the life of their website.

 

5. Best CTA Keyword

The best CTA keyword anyone can use for conversions is: Free. Everyone loves free stuff. Free consultation. Free website review. Free 30 day trial. The word should always be posted prominently, usually on a button or headline. 

6. Video CRO Tips

7 CRO Tips For Videos

1. Keep the video 15-30 seconds long max.

2. If selling a product, have a close up of the product right at the first second.

3. If selling a service, make sure the first second has a clip that explains what is going on. For example, a mechanic is fixing a car. The service is car mechanic.

4. Include the City/State where this product or service is offered.

5. Make the ad fun and/or educational.

6. Have a call to action at the end of the video. Something like: Call Us Today At....  or Visit us at Website.com to buy.

7. Add sub-titles so people can read in case the volume is down.

6. Contact Form VS Calendly AB Test

Interesting A/B test shows 40% more leads through the contact form submission VS calendly submissions. It would probably be best to have both options available.

10. How Comedy Boosts Conversions

CRO Conversion Boost Tip:   One of the best ways to boost CRO is to put a funny video (or image) below the product on a website. It shouldn't be cheesy or basic comedy. It has to be hilarious. I can't find them but I saw one of a cartoon product demonstration that had funny noises and images for 2 minutes long. This video boosted sales immediately by about 35%. The visitor appreciates the entertainment which makes them think of the product and consider buying it. The product should always be the main feature of the video or image. Here is a pretty good example I found. The funny part is that this old lady gets tackled but isn't hurt. Betty White's Snickers Commercial (edited) 

11. AB Test On Homepage Layout

Flos boosted orders by 125% simply by changing the homepage layout. The traditional homepage layout with a header and "shop now" button plus bestsellers below was changed to a clear category based layout which is what boosted the orders. This is because the visitors were more clear on their options as soon as they land on the page which reduces bounce rate and increases conversions.

Flos optimized its website conversion funnel and increased the checkout rate by 125%

Goal

Flos USA faced a significant challenge—low checkout conversion rates on their website. Determined to address this issue, the Flos team embarked on a strategic and process-oriented optimization journey for their website.

Observations

Leveraging behavior analytics tools such as heatmaps, scrollmaps, and session recordings, they identified the pain points at each stage of the visitor journey.

From the homepage to the listing page, product page, cart page, and checkout—the team wanted to implement targeted enhancements. For instance, they wanted to improve the homepage layout for better site navigation, enhanced visibility, and streamlined visitor access to products. In the product listing, a similar approach was expected to improve navigation and product discovery.

Tests

Consequently, specific changes were made on the product page, such as updating the “Choose Finish” option to showcase color swatches. This adjustment reduced visitors’ confusion and encouraged them to add more items to the cart. Similarly, on the cart page, streamlining information and retaining a clear header with a link to the cart page helped visitors consume information.

Implementing these systematic changes based on visitor behavior yielded great results. Flos USA experienced a staggering 125% increase in checkout conversion rates, translating to an impressive 18X return on investment. This success underscores the importance of a data-driven and visitor-focused approach to the conversion rate optimization of a website.

12. Boosting Conversions By Avoiding Confusion

CRO Tip. Confused customers bounce and orders are lost. Here is a perfect example. This shopify store has a local city delivery cost of $4.99 and $32 for nationwide US shipping. The customer has to also input a zip code and click the right shipping button for this to work. This has caused a lot of confusion and some customers actually emailed saying they cannot order. The solution is to remove the confusion by removing this whole section that asks them to put zip codes or pick local VS national. Then, adjust the shopify settings to auto-detect the zip code and provide the shipping charges at the end of checkout. Plus we don't want to scare them with the shipping charges until the very end of checkout.

13. Why Conversions Change During The Holidays

CRO Tip - One of the main conversion rate variables are the Holidays. Holidays can either help or hurt sales. Right now, many people are just on vacation and not really shopping much so sales go down for certain industries. Other industries like Restaurants boost sales because many go out for dinner with their families at this time.

14. AB Test In Hero Section Boosts Conversions

This AB test boosted conversions by 100% just because we got rid of the header image and pushed the best seller product up to the top of the hero section. Best sellers are best placed in the top of the hero section.

 

15. AB Test With Countdown Timer Boosts Conversions

An AB test was run on a popup. The B test had a countdown timer on it and popup conversions boosted by 7.97%. Countdown timers tell the customer that this is their only chance to get the offer so people naturally get more motivated to convert.

16. How Spinning Circles Boosts Conversions Through Hypnotizing Customers

Top Secret CRO Tip - This is actually a secret of big corporations and gov which they don't teach because they don't want you to know. Spinning circles hypnotizes the viewer and draws them into the ad or news station that wants you to believe something. So the big news networks always have variations of this which they put in the beginning of the show. This way, the viewer stays on the channel and absorbs the message. Sometimes the news station is secretly promoting a particular company (example they are pushing stock purchases in the subway) so they will say something very positive about the stock and people just go buy. The subway stock goes up and the spinning circles boost up those sales. Here's an example of 1 variation of the BBC spinning circles: BBC NEWS intro - here's one from CNN in the United States: CNN Intro - They all have similar spinning circle motions.

20. Tips On Forms To Boost Conversions

CRO Tip - The less people have to fill out on the lead generation form, the more lead conversions are made. Typically the main important data to collect are Name, Phone Number, Email and Website which is 4 fields but that can be reduced to 2-3 fields depending on what the website needs. Some websites only need a name and email address. Either way, the longer the form the less conversions.

A widely cited UX study by Nielsen Norman Group found that about 57% of total viewing time is spent on content above the fold, with only 17% on the second screenful and the remaining 26% spread further down the page. This means the most important stuff like a lead form, phone number or best seller list should always stay in the hero section as much as possible. Here is the study: Scrolling and Attention - NN/G
