The Complete Guide to A/B Testing

What is A/B Testing?

A/B testing (sometimes called split testing) is comparing two versions of a web page to see which one performs better. You compare two web pages by showing the two variants (let’s call them A and B) to similar visitors at the same time. The one that gives a better conversion rate, wins!

All websites on the web have a goal — a reason for them to exist

  • eCommerce websites want visitors buying products
  • SaaS web apps want visitors signing up for a trial and converting to paid visitors
  • News and media websites want readers to click on ads or sign up for paid subscriptions

Every business website wants visitors converting from just visitors to something else. The rate at which a website is able to do this is its «conversion rate». Measuring the performance of a variation (A or B) means measuring the rate at which it converts visitors to goal achievers.

Why Should You A/B Test?

A/B testing allows you to make more out of your existing traffic. While the cost of acquiring paid traffic can be huge, the cost of increasing your conversions is minimal. To compare, a Small Business Plan of Visual Website Optimizer starts at $49. That’s the cost of 5 to 10 Google Adwords clicks. The Return On Investment of A/B testing can be massive, as even small changes on a landing page or website can result in significant increases in leads generated, sales and revenue.

What Can You Test?

Almost anything on your website that affects visitor behavior can be A/B tested.

  1. Headlines
  2. Sub headlines
  3. Paragraph Text
  4. Testimonials
  5. Call to Action text
  6. Call to Action Button
  7. Links
  8. Images
  9. Content near the fold
  10. Social proof
  11. Media mentions
  12. Awards and badges

Advanced tests can include pricing structures, sales promotions, free trial lengths, navigation and UX experiences, free or paid delivery, and more.

A/B Testing and SEO

Google cleared the air on the SEO implications of A/B testing in their blog post titled » Website Testing And Google Search «. The important bits from that post are:

Cloaking — showing one set of content to humans, and a different set to Googlebot — is against our Webmaster Guidelines, whether you’re running a test or not. Make sure that you’re not deciding whether to serve the test, or which content variant to serve, based on user-agent. An example of this would be always serving the original content when you see the user-agent «Googlebot.» Remember that infringing our Guidelines can get your site demoted or removed from Google search results — probably not the desired outcome of your test.

Use 302s, not 301s.

If you’re running an A/B test that redirects users from the original URL to a variation URL, use a 302 (temporary) redirect, not a 301 (permanent) redirect. This tells search engines that this redirect is temporary — it will only be in place as long as you’re running the experiment — and that they should keep the original URL in their index rather than replacing it with the target of the redirect (the test page). JavaScript-based redirects are also fine.

Only run the experiment as long as necessary

The amount of time required for a reliable test will vary depending on factors like your conversion rates, and how much traffic your website gets; a good testing tool should tell you when you’ve gathered enough data to draw a reliable conclusion. Once you’ve concluded the test, you should update your site with the desired content variation(s) and remove all elements of the test as soon as possible, such as alternate URLs or testing scripts and markup.

A/B Testing Process

The correct way to run an A/B testing experiment is to follow a scientific process. It includes the following steps:

  1. Study your Website Data: Use a website analytics tool such as Google Analytics, and find the problem areas in your conversion funnel. For example, you can identify the pages with the highest bounce rate. Let’s say, your homepage has an unusually high bounce rate.
  2. Observe User Behavior: Utilize visitor behavior analysis tools such as Heatmaps, Visitor Recordings, Form Analysis and On-page Surveys, and find what is stopping the visitors from converting. For example, “The CTA button is not prominent on the home page.»
  3. Construct a Hypothesis: Per the insights from visitor behavior analysis tools, build a hypothesis aimed at increasing conversions. For example, “Increasing the size of the CTA button will make it more prominent and will increase conversions.”
  4. Test your Hypothesis: Create a variation per your hypothesis, and A/B test it against the original page. For example, “A/B test your original home page against a version that has a larger CTA button.” Calculate the test duration with respect to the number of your monthly visitors, current conversion rate, and the expected change in the conversion rate. (Use our Bayesian Calculator here.)
  5. Analyze Test Data and Draw Conclusions: Analyze the A/B test results, and see which variation delivered the highest conversions. If there is a clear winner among the variations, go ahead with its implementation. If the test remains inconclusive, go back to step number three and rework your hypothesis.
  6. Report results to all concerned: Let others in Marketing, IT, and UI/UX know of the test results and the insights generated.

Your First A/B Test

Starting conversion optimization with Visual Website Optimizer is incredibly easy. Essentially, it is just four simple steps.

1. Include the Visual Website Optimizer code snippet in your website

Including the code snippet means we are now ready to run the tests you create on your website. For further ease, we have plugins for WordPress , Drupal and Joomla that make the process hassle free.

2. Create variations using the WYSIWYG Visual Editor

Load your website in the Visual Editor and create any changes using the simple point-and-click interface. Advanced users can even make CSS and JS code changes.

3. Choose your goals

All A/B tests have goals whose conversion rate you want to increase. These goals can be straight forward (clicks on links, visits page) or could use advanced custom conversion code.

4. Start and track your test

And that’s it, your test is ready to go live. Reporting is real-time so you can start seeing reports as soon as visitors arrive on a live test.

What is the purpose of a vitamin B-12 level test?

Vitamin B-12 is necessary for several bodily processes, including nerve function and the production of DNA and red blood cells.

A person whose vitamin B-12 levels are outside of the normal range will require treatment. Low levels of the vitamin can cause neurological symptoms, as well as fatigue, constipation, and weight loss. High B-12 levels may indicate liver disease, diabetes, or another condition.

Read on to learn more about testing B-12 levels and what the test results mean.

Why is a vitamin B-12 level test useful?

The vitamin B-12 level test checks how much vitamin B-12 is in the body. The results can help doctors to determine if abnormal vitamin B-12 levels are causing symptoms.

A doctor may order a vitamin B-12 level test if a person has any of the following:

Suspected vitamin B-12 deficiency

Researchers believe that up to 15 percent of people in the United States have vitamin B-12 deficiency. Signs and symptoms of deficiency include:

  • confusion
  • dementia
  • depression
  • difficulty maintaining balance
  • fast heartbeat
  • numbness and tingling in the hands and feet
  • poor memory
  • a sore mouth or tongue

Infants with vitamin B-12 deficiency may fail to thrive. They may experience movement problems in addition to delayed development.

Pernicious anemia

People with symptoms of pernicious anemia may also need a vitamin B-12 level test. Pernicious anemia, which causes low levels of red blood cells, results from an inability to absorb vitamin B-12.

It often affects older adults or those who are lacking intrinsic factor. Intrinsic factor is a substance in the stomach that binds to vitamin B-12 so that the body can absorb it.

Symptoms of pernicious anemia include:

  • constipation
  • fatigue
  • loss of appetite
  • pale skin
  • weakness
  • weight loss

High serum folate levels

Serum folate is the level of folic acid in the blood. High serum folate levels can mask the symptoms of vitamin B-12 deficiency and make its neurological symptoms worse.

They can also increase the likelihood of anemia.

Symptoms of other conditions

An abnormally high vitamin B-12 status can be an early sign of liver disease, diabetes, or certain types of leukemia. A doctor may use the results of a vitamin B-12 test to help form their diagnosis.

Risk factors for low vitamin B-12 levels

Certain people are more at risk of vitamin B-12 deficiency than others, especially those who have low stomach acid or other digestive issues. Stomach acid separates vitamin B-12 from food so that the body can absorb it more efficiently.

The following groups of people are more likely than others to experience low vitamin B-12 levels:

  • older adults
  • children
  • vegans and vegetarians
  • people with diabetes
  • people with conditions that reduce vitamin B-12 absorption, including celiac disease and Crohn’s disease
  • people who have had gastric bypass surgery
  • those who are breast-feeding
  • people who are taking medicines such as chloramphenicol, proton pump inhibitors, or H2 blockers

How does the vitamin B-12 level test work?

Doctors usually use a blood test to check vitamin B-12 status, but home urine tests are also available. A doctor can check vitamin B-12 as part of a standard blood test.

Although it is not necessary to fast before a B-12 test, a person may need to if the doctor is also using the test to look at other components in the blood.

It is important that individuals tell their doctor about any medications and supplements they are taking, as some can affect the results.

Understanding the results

The results may be:

  • Normal. The normal range for vitamin B-12 in the blood is between 200 and 900 nanograms per milliliter (ng/mL). People at the lower end of this range may require follow-up testing, especially if they have symptoms.
  • Low. Levels of vitamin B-12 are low if they are below 200 ng/mL. This result suggests a vitamin B-12 deficiency, pernicious anemia, or an overactive thyroid. People with low vitamin B-12 levels often experience neurological symptoms.
  • High. An abnormally high vitamin B-12 status is anything over 900 ng/mL. This result may suggest liver or kidney problems, diabetes, or certain forms of leukemia.

The result ranges vary from one laboratory to another, so it is important to discuss the results and their meaning with a doctor.

The doctor may also check the levels of methylmalonic acid (MMA) and other substances to evaluate for vitamin B-12 deficiency. These lab values help detect a vitamin B-12 deficiency during the early stages.

Treatment for low vitamin B-12 levels

Individuals with low vitamin B-12 levels often require regular injections of the vitamin. These shots are more effective than supplements at raising vitamin B-12 levels, especially when people have medical conditions that may make it more difficult to absorb supplements.

For some people, high doses of vitamin B-12 supplements may improve B-12 status. Supplements are available in capsule or liquid form from pharmacies, supermarkets, health stores, and online. It may also be helpful to eat more foods that are rich in vitamin B-12.

Treatment for high vitamin B-12 levels

There is no upper limit for vitamin B-12 intake because consuming high levels does not cause problems. However, having naturally high levels of vitamin B-12 in the body may be a cause for concern, as it suggests a severe underlying condition. Doctors will aim to treat the underlying medical condition, rather than the elevated levels of vitamin B-12.

Food sources of vitamin B-12

Although absorption difficulties and other medical issues often cause low vitamin B-12 levels, some people may be deficient because they do not get enough vitamin B-12 from their diet. This is especially true for vegans and long-term vegetarians.

Foods rich in vitamin B-12 include:

  • fish and seafood
  • meat
  • eggs
  • dairy products
  • fortified plant-based dairy alternatives
  • fortified breakfast cereals
  • fortified nutritional yeast

Vitamin supplements can make up for a shortfall in the diet, especially for vegans and strict vegetarians. As it can be easier for their body to absorb supplements than naturally occurring vitamin B-12, older adults should aim to meet their vitamin B-12 needs through fortified foods and vitamin supplements.

Recommended dietary allowances of vitamin B-12

Adults and adolescents over 14 years of age require 2.4 micrograms (mcg) of vitamin B-12 daily. This increases to 2.6 mcg during pregnancy, and 2.8 mcg when breast-feeding.


Vitamin B-12 is an essential nutrient that plays a vital role in overall health. A vitamin B-12 level test determines a person’s vitamin B-12 status. A doctor may recommend this test to people who have symptoms of a deficiency or who have a higher risk of low vitamin B-12 in the body.

People can avoid vitamin B-12 deficiency by eating a balanced diet and including several sources of vitamin B-12 daily or taking supplements. If they have issues absorbing vitamin B-12 from food sources, oral supplements or injections of the vitamin can help to prevent symptoms and complications.

Test A/B

Le test A/B (ou A/B testing ) est une technique de marketing qui consiste à proposer plusieurs variantes d’un même objet qui diffèrent selon un seul critère (par exemple, la couleur d’un emballage) afin de déterminer la version qui donne les meilleurs résultats auprès des consommateurs. C’est une technique particulièrement employée dans la communication en ligne où il est maintenant possible de tester auprès d’un échantillon de personnes plusieurs versions d’une même page web, d’une même application mobile, d’un même e-mail ou d’une bannière publicitaire afin de choisir celle qui est la plus efficace et de l’utiliser à large échelle.

En français, le test A/B est habituellement un terme générique pour qualifier tout type de testing . Par exemple, on englobe sous ce terme les tests A/A, A/Z ainsi que les tests multivariés (ou tests MVT). Plus il y a de trafic sur un site, plus il est possible de tester de versions simultanément.


Le principe Modifier

Un test A/B permet d’évaluer les performances respectives d’une ou plusieurs versions partiellement ou totalement différentes d’une même page web en les comparant à la version originale. Le test consiste à créer des versions modifiées de la page originale en modifiant autant d’éléments qu’on le souhaite ou que le trafic le permet (contenu, aspect général, présentation…) [ 1 ] , [ 2 ] .

Un test A/B permet de mettre en concurrence deux versions de pages afin d’en améliorer l’efficacité (optimiser le taux de transformation, le chiffre d’affaires…). Les tests sont réalisés à l’aide d’un logiciel, souvent en mode SaaS ( Software as a Service ), qui s’assurera que les deux pages reçoivent un nombre de visiteurs identique et qui en analysera les résultats [ 2 ] . Ainsi, on scinde les visiteurs en deux groupes (d’où le nom A/B) et on leur affiche à chacun une version de page différente. L’on suit alors le parcours des deux groupes en temps réel, et on regarde laquelle des deux donne le meilleur résultat par rapport à un objectif donné [ 3 ] .

Grâce au testing , et plus précisément lors de tests multivariés, il est possible de créer une multitude de combinaisons d’éléments sur une page web afin de tester la présentation, le contenu ou l’aspect général de celle-ci. Parmi ces éléments, l’on peut par exemple tester [ 4 ] :

  • les boutons ;
  • les images ;
  • un texte ;
  • la présence de vidéos ;
  • la couleur ;
  • la taille d’éléments ;
  • l’efficacité d’une landing page ;
  • les éléments d’une newsletter.

Autres termes utilisés Modifier

  • Test A/A : Vérifier la précision de l’outil statistique d’un module d’A/B testing [ 5 ] .
  • Test A/B : Comparer deux versions d’un même élément.
  • Test A/Z : Comparer plus de deux versions d’un même élément.
  • Test multivarié : Comparer plusieurs combinaisons d’éléments.
  • Test multi-pages : Comparer des variations liées sur plusieurs pages.

Exemple du testing dans la campagne 2008 de Barack Obama Modifier

Un exemple concret de testing peut être trouvé lors de la campagne présidentielle de Barack Obama en 2008 [ 6 ] . Les développeurs du site Internet de la campagne ont ainsi testé à la fois différents boutons, différentes images, et ont également testé l’influence de vidéos à la place des images.

Dans cette expérience, quatre boutons et six médias (trois images et trois vidéos) ont été combinés les uns aux autres de façon à obtenir 24 combinaisons différentes afin de déterminer laquelle permettait d’obtenir le taux de souscription le plus élevé.

La combinaison gagnante a obtenu un taux de souscription de 11,6 % alors que la page originale avait un taux de souscription de 8,26 %. Concrètement, la nouvelle page optimisée a permis d’obtenir 2 880 000 souscriptions supplémentaires donc autant d’adresses e-mail. Cette technique a eu deux effets bénéfiques principaux : le nombre de bénévoles pour la campagne a augmenté proportionnellement aux souscriptions, et le nombre de donations a également augmenté.
