The UK Government Data Standards Catalogue suggests 35 characters for each of First Name and Surname (h/t Ian Nelson on Stack Overflow). That's how many characters you should assume for displaying the name or accepting input. However, I don't think a text field needs to be 35 characters wide. (Johnjacobjingleheimerschmidt should be able to type his name, ...

Hard Limits In the 10ms-5ms range you're running into the refresh rates and response times of pixels on your monitor. Many monitors are limited to 60Hz (17ms refresh). You're also getting close to limits of visual perception. We take around 100ms to direct our eyes to something new that has appeared on screen. Noise The difference between a compile ...

No, neither is better. They deal with different aspects or strategies, and in general you need both. A small change lets you refine your design and have a better understanding of what affects conversion, but may let you end up with a local maxima. A more radical change with many elements will not help you understand what affects conversion, but may also ...

While not talking about response times as low as the question, there are some very interesting results from tests carried out by Google and Bing here: http://radar.oreilly.com/2009/06/bing-and-google-agree-slow-pag.html The bottom line is that users interact more with responsive web pages and the companies made more profit. I would think it's not too ...

There are two separate properties to consider here; the character space on screen and the number of characters that will be accepted. You could use a text field box where the user can continue typing and the previous content moves off-screen. Your aim here is to have a visible space big enough for most people to fit their names into, and to be large enough ...

Kudos for the effort - very nice! I have a few comments about the list at the end: Personally I feel tag clouds aren't very useful. The order between the elements isn't clear, it's not always easy to see which is bigger and you don't know what are the tags sorted by. As for your second suggestion, I might have a tiny improvement, but it doesn't feel ...

It sounds like you need multivariate testing. For example, select four elements on the page you'd like to test. You could radically redesign each of the elements so that in one version of the test, you're testing a mostly redesigned page. Then those four elements would be turned "on" or "off" alternately. You'd end up with 16 variations against your control ...

Was this a One-tailed Test? First of all, I think your statistical test is giving you a 1-tailed p-value, rather than a 2-tailed p-value that you should use in what sounds like exploratory work. I think you’re saying your p-value is 0.02 (i.e., there is a 2% chance of getting the observed difference in conversions by random luck). However, if the number of ...

Your client is basically correct - your users need to be able to find what they are looking for quickly and efficiently - not only is this good UX, but in e-commerce it improves conversions and therefore profit. However, their insistence that all three menus be visible at once is misguided and perhaps even detrimental to the fundamental user goal mentioned ...

Although all of the above could be part of a UX designers role if you are focused purely on analytics and conversions then potential roles titles would probably include the word analyst and be prepended by: Business/web/marketing/digital. http://www.clickz.com/clickz/column/1712911/becoming-experienced-invaluable-web-analyst The other angle to approach it ...

Traditionally, common wisdom used to hold that any list should always contain between five and nine items (seven plus or minus two), because humans find it hard to remember more than seven items at a time. However, that only really applies if the user actually has to remember all the items in the first place - and that only counts if the user can't make ...

I'm restraining myself from ranting about designing web experiences, especially mobile, as PSD layouts to be "sliced up". You might consider gently suggesting that your designers google "responsive web design" and "mobile first" and read the conversations/debates around design approaches for the modern, multi-device web. Wait, I said I wouldn't rant, didn't ...

When designing for handheld devices you need understand the following concepts Screen size - Actual physical size, measured as the screen's diagonal. Screen density - quantity of pixels within a physical area of the screen; usually referred to as dpi (dots per inch). Orientation - orientation of the screen from the user's point of view. landscape or ...

I learned, that in program usage, interaction delays below 0.2 s aren't recognised. A fast secretary makes 600 hits per minute, which is 10/s, most users won't reach 300/min or 5/s. A response faster than 0.2 s is felt as immediate response. You needn't be faster than that.

For the next 20 to 50 years, the driving factors in the future of transportation are safety, congestion, and energy efficiency. All three are interrelated. The primary enabling technologies are increasingly cheap and powerful embedded electronics and software for data sensing, transmitting, analysis, and storage. What this means for vehicles in general and ...

Maybe use font-size-weighted or font-color approach?

I think that the daunting list of tags on this site makes me avoid as subconsciously it scares me by being so long. I think limiting it to top ten with an option to see all of them would make user scan it quickly and see what it going on within a matter of seconds. Also, I could never understand how the tags were sorted. It seems to me that they are sorted ...

How about querying the form-factor / resolution and then loading the corresponding set of images? Just a thought.

The right number to enable efficient navigation. Which isn't a lot of help, I know, but there is not a completely fixed answer. Sometimes, a large sublist will work, if the user can find what they need easily (if it is alphabetical, and there is a clear reason for many items). Sometimes, the lists need to be smaller, because the user needs to make decisions ...

In general I would say yes. Search engines want to return the best results so the most usable sites are a part of that. Let's run through some of the main on-site optimizations: Page titles in <title> tag: The page title is shown in several places: the browser's window title bar and/or tab, bookmarks (as default name), search results and often in ...

When SEO is done well and honestly, it helps make a good first impression to the visitor who arrives from a web search, as they will find what they expected. If someone looks at a page of results and chooses one because they think it seems right, but arrives on a site that doesn't seem to deliver, they very quickly become frustrated and start off with the ...

If you are doing proper SEO practices and applying the usability process you will generally succeed at a strong user experience and have good SEO performance. As part of the UCA process you will have identified the audience and will have generated (card sort, etc) keywords relevant to that audience to apply throughout navigation and site content. As part of ...

'findability' is an aspect of usability. SEO would improve that aspect. But there's so many flavors of SEO that it's hard to say it's blanket true. Most black hat SEO, for instance, is typically bad for UX.

Users generally want to see a summary page or confirmation page before submitting payment. Even when they have only selected one item. I still think it would be a good idea for you to do A/B testing yourself - at least for this purpose, I wouldn't rely on data from another site. There are too many variables involved with A/B testing and just because a ...

The most common job title for the role you are looking to fill would be Conversion Optimization Strategist. This differentiates the position from an Analyst which would include analyzing, setting up and maintaining your overall Google Analytics account.

It depends on when the savings occur. CPM-GOMS studies (http://www.rpi.edu/~grayw/grayres/ernestine.html) showed that expected gains in efficiency of a new system may not be realized because many tasks may rely on other outside activities that will negate the savings. If your taks is highly sequential, you will see the gains, if not, it is less likely to ...

What is the difference between 'Contract', 'Sales' and the various 'Shop' options? I would mention to your client that as a best practice, navigation is often kept to 5-9 items in accordance with Miller's Law. However, this is not to say that all navigation is limited to a maximum of 9 items. Different groupings, placement within the website, and design ...

Without having the site in front of us it's probably hard for us to come up with some specific theories. However - some things to think about. How sure are you of the experimental methodology? Could there have been an error? Are you sure that the different options were presented randomly over the whole lifetime of the experiment? If not then external ...

The most effective people for running A/B testing are those with strong all-round UX skills. Afterall it's just another tool to use for optimising your website and improving the user experience. I'd recommend that they are also fairly analytical so they understand conversion rates and uplift etc.

You could always argue that being a slave to the machine doesn't actually help you 'get more done during' in a day's work. There are higher levels of brain activity than those involved in managing a software interface. Not having 'instant gratification' can sometimes be a good aid to having to sit down and think a bit more deeply about something.
