Sample Size & Reliability

The more people find the same problem, the more reliable the data set becomes.

Multiple Rounds of Testing

Multiple round of testing on 5 different users covers more issues than a single round of testing with the same number of users.

User 1 User 6 User 11 User 1 User 9
User 2 User 7 User 12 User 2 User 10
User 3 User 8 User 13 > User 3 User 11

Scenarios

Quick simple functions Provide the partecipant context and direction
Easily completed without any background information given Set the stage, tell the story
Find the Search button Increase overall understanding
Where would one go to out information about specific terms Help the user apply the situation to themselves
Give them an action to perform

 

Usability Scenarios

  1. Uses the vocabulary that the participant uses.
  2. The actions are clear and precise.
  3. Provides all the details needed to complete the goal.
  4. Does not provide steps and definitely does not give away the answer.
  5. You would like to buy a car, you would like to lease it for 36 months term with 1500 down. How would you do this?

Rating your results

a. Easy or under a minute to find/answer – – – —2 points

b. Difficult, takes 1-2 minutes to find/answer —-1 point

c. Fail, takes over 2 minutes to find/answer ——0 point

 

Types of Usability Tests

Formative Testing

Formative testing is usually conducted during website development and is typically used to test a specific feature like the design of a button or the findability of a piece of specific content, etc…

For example: is the user able to find the email form and be able to subscribe to the newsletter? Or is the user able to find a piece of content given the labeling of the button?

 

Summative Testing

Summative testing is conducted at the end of the development, the “Summation” of the development process. Summative testing is used to determine whether a website has successfully accomplished all of its goals.

 

Qualitative vs. Quantitative Testing

Related to, measuring, or measured by the quantity/quality of something rather than its quality/quantity.

 

Revenue protection: Preventing Web Scraping

Web scraping, known as content scraping, data scraping, web harvesting, or web data extraction, is a way of extracting data from websites, preferably using a program, or bot (short for web robots) that sends a number of HTTP requests, emulating human behavior, getting the responses and extracting the required data out of them.

Tips to increase conversion rate

The basics

Conversion rate is the percentage of users who take a desired action; and measures what happens once people are at your website. Typical examples of actions or events you would like to track the conversion rates are: the percentage of website visitors who fill out a form, purchase a service or product from your online store, share your content on their social media sites, became a registered user, sign up for subscriptions, use a certain feature and so on.

The measurement period you should use is highly depended by your type of business. The key criteria to use to deciding on the period length are:

  1. The time period should be short enough to make an impact on your business but long enough to remove any seasonality/random fluctuations. The trade-off between getting robust data and actionable insights can be solved comparing your current weekly data set with both your historical and forecast trends adjusted with seasonality indexes.
  2. The measurement period should be aligned with you product cycle. Hence, if you follow an agile monthly release plan timetable, then your measurement needed to be adjusted accordingly.  

Optimizing your conversion rates can drastically improve your revenues without raising any additional marketing costs. In 2013, e-commerce sites averaged around 3% conversion rates. When you build up your optimizing model, you shall always keep in mind customers’ price elasticity model.

On general terms, suppose you spend 1,000 on advertising each month to bring 1,000 prospective customers to your website. If your online sales conversion rate is 2.5%, then you’ll secure 25 new customers. Alternatively, if your conversion rate improved to 3%, you would gain 30 new customers. In this latter scenario, you’d gain an additional 60 customers y-on-y for no additional advertising cost, thus boosting your profits significantly.

The Tips to increase your conversion rates

Tip 1: Serve your customers with a simple layout

Study your users’ mental process and noted what actions they expected to perform to achieve their goals. Look at what both your competitors and peers websites are doing it. Then make your website layout easy to be immediately understood, so that when users land over your site they will never ask themselves what to do next. If you sell your product/service globally, then make sure to at least provide your prospects with a localized payment service.

Tip 2: Clearly show the call to action

Make sure that all relevant information, as well as a clear and stand out of the crown call to action is on the most visible and predominate part of your page. In other words, keep the process simple and linear.  

Tips 3: Serve then a quick conversion process

Make each check out steps as streamlined and linear as possible. Give users the option of move back to previous steps, but do not ask them to do so. If additional information is needed to complete the process, then add an additional step rather than push users on an already supposed completed section. Add, when possible, in line help.

A happy customer is likely to use your site again. Then, serve them a tokenization payment process.

Tips 4: Be Credible

Having a trust seal, such as Verisign will always help you increase conversions. Don’t forget to provide contact information including business address, email contact, and phone number at each step as well as clear information about your return and exchange polices. In this way you will increase the confident users have on your websites, as well as limiting your charge back exposure.

Tips 5: Sell emotions not just products

Many people buy for emotional reasons. Make sure they can interact with their social media peers whilst on your website. Know your Unique Selling point and make sure users will be able to feel the same experience whatever touch points they choose to interact with your brand.   

Give your image a human touch. Do not use a mascot or a virtual image on any of your pages, especially when leads/buyers interact with your client desk, but rather publish the image of the best performing representative on your client service team.

Tips 6: Be Clear, Open and Honest

Always reply to your customers on timely fashion with a clear and open message. Always put yourself on your customers’ shoes. Do not overwhelm them with lots of email, but send them coupons and exclusive offers when you know they will likely need them. If a product is out of stock, keep your prospect informed on when it will be available again. Offer the best customer service to your unhappy customers: the viral effect of make just one of those unhappy onto a satisfied buyer will overcome any additional costs.

Tips 7: Keep on testing

Always remember that you can’t improve what you can’t measure. Check your site errors report in real time, your sales daily and your performance weekly. Add A/B testing code to your website, and keep on measuring and testing any important feature.
