In Defense Of A/B Testing

Recently, A/B testing has come under (unjust) criticism from different circles on the Internet. Even though this criticism contains some relevant points, the basic argument against A/B testing is flawed. It seems to confuse the A/B testing methodology with a specific implementation of it (e.g. testing red vs. green buttons and other trivial tests). Let’s look at different criticisms that have surfaced on the Web recently and see why they are unfounded.

Jason Cohen, in his post titled Out of the Cesspool and Into the Sewer: A/B Testing Trap, argues that A/B testing produces the local minimum, while the goal should be to get to the global minimum. For those who don’t understand the difference between the local and global minimum (or maxima), think of the conversion rate as a function of different elements on your page. It’s like a region in space where every point represents a variation of your page; the lower a point is in space, the better it is.

The Ultimate Guide To A/B Testing

A/B testing isn’t a buzz term. A lot of savvy marketers and designs are using it right now to gain insight into visitor behavior and to increase conversion rate. And yet A/B testing is still not as common as such Internet marketing subjects as SEO, Web analytics and usability. People just aren’t as aware of it. They don’t completely understand what it is or how it could benefit them or how they should use it. This article is meant to be the best guide you will ever need for A/B testing.

A/B testing example

At its core, A/B testing is exactly what it sounds like: you have two versions of an element (A and B) and a metric that defines success. To determine which version is better, you subject both versions to experimentation simultaneously. In the end, you measure which version was more successful and select that version for real-world use.

The Principles Of Cross-Browser CSS Coding

It is arguable that there is no goal in web design more satisfying than getting a beautiful and intuitive design to look exactly the same in every currently-used browser. Unfortunately, that goal is generally agreed to be almost impossible to attain. Some have even gone on record as stating that perfect, cross-browser compatibility is not necessary.

Cross-Browser CSS

While I agree that creating a consistent experience for every user in every browser (putting aside mobile platforms for the moment) is never going to happen for every project, I believe a near-exact cross-browser experience is attainable in many cases. As developers, our goal should not just be to get it working in every browser; our goal should be to get it working in every browser with a minimal amount of code, allowing future website maintenance to run smoothly.

In this article, I'll be describing what I believe are some of the most important CSS principles and tips that can help both new and experienced front-end developers achieve as close to a consistent cross-browser experience as possible, with as little CSS code as possible.

Cross-Browser Testing: A Detailed Review Of Tools And Services

As you probably know, cross-browser testing is an important part of any developer's routine. As the number of browsers increase, and they certainly have in recent years, the need for automatic tools that can assist us in the process becomes ever greater. In this article, we present an overview of different cross-browser testing applications and services. Surely, you are already familiar with some of them, and you may have even stumbled across another overview article, but this one takes a different approach.

This is not just a list of available tools, but rather a comprehensive analysis based on my experience with each of them. For the impatient among you, a summary table is at the end summarizing key metrics and unique features for each service. But if you're interested in my personal experience with these tools, then read on.

Find The Right JavaScript Solution With A 7-Step Test

As Web developers and designers, we are spoilt for choice right now. To build a complex Web application or even just spice up a website with some highly interactive interface element, we have hundreds of pre-built solutions to choose from. Every library comes with widgets and solutions, and every developer tries to make a name for him or herself by releasing a funky JavaScript solution to a certain interface problem. We can pick from dozens of menus, image carousels, tabs, form validators and "lightboxes."

Disable JavaScript with the web developer toolbar

Having this much choice makes it easy for us to pick and choose, which is where things go wrong. In most cases, we measure the quality of a solution by its convenience to us. Our main reasons for picking one solution over another are: Does it do what I need it to do? Does it look cool? Does it sound easy to use? Would I want to use it? Does it use the framework I'm committed to?

How To Support Internet Explorer and Still Be Cutting Edge

Everyone has been going on about how we should use CSS3 more and all of the possibilities and flexibility that come with it, but that we should still consider IE6 and other troubling browsers. But how do we actually do that? How do we create websites that are up to date with the latest coding techniques but that are also usable for people experiencing the Web on Internet Explorer?

In this article, we’ll see what measures we can take to provide a good experience for IE users but keep moving on. We will mainly focus on the CSS part but will also provide some handy tips on dealing with overall markup.

CSS Differences in Internet Explorer 6, 7 and 8

One of the most bizarre statistical facts in relation to browser use has to be the virtual widespread numbers that currently exist in the use of Internet Explorer versions 6, 7 and 8. As of this writing, Internet Explorer holds about a 65% market share combined across all their currently used browsers. In the web development community, this number is much lower, showing about a 40% share.

Screenshot

The interesting part of those statistics is that the numbers across IE6, IE7, and IE8 are very close, preventing a single Microsoft browser from dominating browser stats — contrary to what has been the trend in the past. Due to these unfortunate statistics, it is imperative that developers do thorough testing in all currently-used Internet Explorer browsers when working on websites for clients, and on personal projects that target a broader audience.

This article will attempt to provide an exhaustive, easy-to-use reference for developers desiring to know the differences in CSS support for IE6, IE7 and IE8.
