Upgrading a great website

Last year I was at the award ceremony of the Usability Awards 2010. For the website there was a honorable mention. During this ceremony I learned some things to improve the website.

This is what I have done:

  1. Changed the font from serif to sans-serif.
    This change has some impact. The top menu was too large now, so 
  2. I had to remove a menu item in the top menu.
    Luckily did this change improve the readability. Due to this change I was able to
  3. Display a darker background.
    Both the old and the new backgroumd was based on a picture of grass. With the new background that is more clear.
    In the bottom menu was the call for action: "Make a reservation now"
  4. I have replaced the call for action in the bottom menu into: "Check availability".
    This is a more inviting call for action. Of course the goal of the website is that people makes reservations, so 
  5. I made clear call to action buttons for "Make a reservation".
    For the call to action buttons I used the same grass background as for the top and bottom menu. It looks really nice.
  6. The text of the bottom menu is modified a little due to the fact there is another call to action now.
  7. At the page "reviews" and "back at home" I have a clear call to action to write a review.
  8. At the contact page there are even three call to action buttons now.
    "Make a reservation", "Write a review" and "Mail".
  9. Very important is of course the call to action button "Make a reservation" at the page "Availability".
  10. At the page "Availability" I have changed the text a little. I includes now the phrase "now" to create an urgency to make a reservation.
  11. The HTML code is upgraded form XHTML 1.0 to HTML 5 for all pages.
    The most important feature of HTML 5 is that you are now able to use
  12. A placeholder for all "text" fields.
  13. The appropiate fields are changed from "text" to "email", "url", "search".
  14. Some fields are marked as required now.
I believe that these small changes improve the usability of the website.

Is it easy to contact the organisation. Is there a real e-mail address or a contact form.

  1.  no e-mail address, there is a contact form;
  2.  e-mail address, no contact form;
  3.  no e-mail address, there is a contact form;
  4.  no e-mail address, there is a contact form wizard;

  8.  e-mail address, no contact form;
  9. e-mail address, but no link to the promised contact form;
  10.  no e-mail address, there is a contact form;
So at the end I think that non of these sites should win the usability award seen from a technical perspective. When I browse the sites I think the winner will be

Trends and Visits

Google Trends gives an overview of the search terms used. Camping related search terms have a strong relation with the season. In the winter nobody cares about the website. However in July a lot of people are searching for a camping.

When you take a look at our visits, you see that we follow this trend.

So I decided that in the summertime I keep the site as is, and make structural improvements in September, October, November and December.

Global Traffic Rank

Discovered a new tool for measuring the popularity of a website What is the most popular site of my favorite list of test sites:

  1. 3121
  2. 3301
  3. 3347391 
  4. 579
  5. 124369 
  6. 183339 
  7. 1999
  8. 148059 
  9. 6154 
  10. 174260 
These numbers are difficult to compare. With the log10 function the numbers are easier to understand. The ranking is:
  1., and  (log10 rounded is 3);
  2. and (log10 rounded is 4);
  3.,, and (log10 rounded is 5);
  4. (log10 rounded is 7).
The top 5 is the same as discovered earlier. See A fistfull of dollars.

The usability test

Okay, what to test when you want to test the usability? The ease of use? Okay, lets try.
Lets buy a book ("priemgetallen").
  1. Search for priemgetallen
    The first result is the right one
  2. Click on "In winkelwagentje"
  3. Click on "Bestellen"
    Login or create an account
  4. Create an account
  5. Fill in the form
    First error made, filled in name instead of given name
    Got a question about the present service allthough I use the same address
  6. Click on continu
    Have to give my e-mail address and a password
    Very bad, I have to un-tick that I want a newsletter
    Very bad, I have to type my e-mail address twice
  7. Click on check the given information
  8. Click on Pay (and stopped)
It is easy, but some things could be improved. Good is that the postal code and the house number was enough.
Lets buy an insurrance for my car
  1. Given the identification of the car and pressed "Bereken je premie"
  2. Given all information, it is clear where you are in the process, however I need to give my email address twice and I have to wait to long to go to the next step
  3. Process stopped at the moment I had to give the "meldcode" I was too lazy to search for it
Lets book a simple course

Selected a course form the homepage, Apple's OSX, selected the first course and then ... did not know what to do next. Process stopped.
Try to book a hotel.

I have to enter the dates first before I can do what I want, I have to search again for the wanted hotel. 
However after found the hotel I want for the price I want I only have to enter my name and e-mail address (twice!). Easy. Process stopped to prevent a reservation.
I want to see the weather as mentioned in the journal of 20.00 o'clock. 

Found in two click the weather report of the 18.00 o'clock journal. Great.
Try to camp with my own caravan in august.

  1. Look at availability
  2. Created a reservation
  3. Checking if the reservation is correct. Process stopped

Best user experience so far.
  3. - Much more information is necessary for a reservation than
Overall score

In my humble opinion should be the winner of the usability award 2010.

The Design test

Testing the design is subjective, however there are some methods which helps.

The small screen test
The first one, is the small screen test. This test is easy to do and I will tell you the result now.

From the following sites, only the Helenahoeve has a seperate design for small screens.

The grayscale test

How good are the designs when you don't see colors at all?

In my opinion,, and are too busy. 

The blur test

Almost the same test, however now we use color, but there was a gaussian blur of 5 pixels. Lets see what it looks like.

Now only from, and it is clear which sitename is involved. The and seems to have the best readable test.

What else could I say about the designs. Personally I prefer the design of nos,nl and has too few battles for these sites. I am curious about the opinion of the Dutch web users (so I have to wait for results of the Usability Award 2010 for this one).

Content test

This is the most difficult test. For each site I have to know what I expect. Okay, lets give it a try. is working hard at several disiplines. Second hand books, toys, you name it and they sell it.

What information do they have about the new Nintendo DS XL or alternatively the Nintendo DSi? Founded very quickly, however it was not directly clear to me that the XL also have two camera's. After a search on Google I found that fact.

Do they have the book titled "help mijn dochter is hoogbegaafd". Yes they have it. However the information about the book is poor. More information is available via a Google search, and you even will find the book in Google books.

On a personal scale of 5 stars, I will give 3 stars (remember this test is subjective).

Ditzo is about insurrance. I want to know what happens if I buy a new car and how much I have to pay after an accident.

No information found about the insurrance when switching cars (sold the old one and bought a new one). No information found about the monthly costs after an accident.

On a personal scale of 5 stars, got zero stars.

Eduhub is about training. It is a very advanced startpage. Lets see what the can tell me about sculpture ("beeldhouwen") and "electro installateur".

Found a 1 day Art event for "beeldhouwen". That's not what I am looking for. Searching for "electro installateur" gave zero results, however searching for "installateur" gave 10 hits. The second hit contained the information I was looking for.

Eduhub got 3 stars (out of 5). It could have been 4 if they have usefull information about "beeldhouwen".

I rarely sleep in a hotel. Too expensive. But hey, lets give it a try. A hotel for a romantic weekend near the sea, and a F1 hotel or something like that near Paris.

Wow, found very quickly a hotel for a romatic weekend I will choose Cape Helius. And now up to the sun. The first day we will make it to Paris (plus minus 50 kilometer). Hmm, something went wrong is a strange message when there are no search results. Ok found that is for hotels in the Benelux.

I will give 4 stars, out of 5.

At it is all about news.

Recently it was not possible to fly. How many people still need their flight? Not found.
Sony stopped with the 3.5 inch disc. Is that a newsitem? Yes, great article.

I don't use often, I prefer, however the content seems ok. 3 stars out of 5 for the content.

I build this site, but hey lets fake that I knew nothing. What would I like to find on this site?

Where is the site about?
Where are the shops?

Found directly where the site is about. No useful information found about "winkels" or "boodschappen", however the information about "Sluis" is ok.

I give 3 out of 5 stars.

So the ranking is:

  1. with 4 stars;
  2.,, and with 3 stars;
  3. with zero stars.

Backbutton working at the whole site? (as far as I know)

  1. Search for book "priemgetallen", found directly 
  2. Search for "wegenwachthulp", "pechhulp", visible at the homepage
  3. Search for "diĆ«tiste", not found, "dietiste", found directly (6 results)
  4. Search for a hotel in Leiden for tonight, found directly 8 hotels available
  5. Search for "kandidaten groenlinks", not found

Candidates Usability Award 2010

The candidates for the usability awards 2010 are:
The scores for the webguidelines are:
  1. 36 points;
  2. 28 points;
  3. 40 points;
  4. 40 points;
  5. 42 points.
The validation results of these sites are:
  1. Not valid, 111 errors;
  2. Not valid, 390 errors;
  3. Not valid, 16 errors;
  4. Valid XHTML Strict;
  5. Valid XHTML Transitional.
Quality is not the same thing as usability.

The loadtime of these sites are:
  1. 4.9 seconds;
  2. 25.7 seconds;
  3. 1 second;
  4. 1.7 seconds;
  5. 1.4 seconds.
So Ditzo is far to slow.

Lipperhey scores:
  1. technical 7.3, seo score 76%, popularity 10, overall score 8.3;
  2. technical 6.7, seo score 74%, popularity 8, overall score 7.4;
  3. technical 7.3, seo score 83%, popularity 8, overall score 7.9;
  4. technical 7.8, seo score 84%, popularity 9, overall score 8.4;
  5. technical 6.6, seo score 71%, popularity 10, overall score 7.9;
How liguid are the designs (when does the horizontal scrollbar appear):
  1. 1 x "CTRL +";
  2. 1 x "CTRL +";
  3. 1 x "CTRL +";
  4. 1 x "CTRL +";
  5. 1 x "CTRL +";
Is it easy to contact the organisation. Is there a real e-mail address or a contact form.
  1. e-mail address plus contact form;
  2. no e-mail address, you have to make a phonecall;
  3. e-mail address plus contact form;
  4. e-mail address, no contact form;
  5. e-mail address, no contact form;
Overall I think that based on these tests should be the winnar. However you should score these websites on the following aspects:
  1. Navigation;
  2. Content;
  3. Design;
  4. Usability (Is the site easy to use).
In a next blog I will answer these questions.

    How fast is fast enough

    Now speed is relevant for your score in Google, people are thinking about the necessary speed. On Seochat they state the following:

    If your website's average loading time is below 9.82 seconds, your website is loading VERY fast as compared to the average websites ranking in Google at Position 1. You do not need to improve in this case.

    Sorry, but even according to the old formula you are slower than everyone else. If you focus on people instead of on Google you should know that the loading time should be 1 or 2 seconds max. See respectively these articles from Jakob Nielsen and Akamai.

    For this test Seochat used  stopwatch from and Google Chrome. I tested several times with this stopwatch in several browsers:
    • 1.9 seconds in Internet Explorer
    • 0.7 seconds in Opera
    • 1.8 seconds in Firefox
    • 0.4 seconds in Google Chrome
    So when you use Internet Explorer you browse roughly 4 times slower than tested. So the consequence is that a performance of 40 seconds should be enough for IE users? I don't think so...

    I promise you, try to be faster than 2 seconds and you will reach much more people who will use your site.

    More candidates for the usability award 2010

    At the website you will find some extra websites who are probably in the race for the usability award 2010.

    At this moment, only has a score of 42 (or more) according to the Web Guidelines Test. So I will not test these sites.

    Candidates for the Dutch Usability Award 2010

    At the site there are 40 websites mentioned as candidate for the Dutch usability award 2010. To test the usability of these sites I decide to check the webguidelines score for these sites. In an earlier test the Helenahoeve got 42 points. I will mention the sites here with 42 points or more:
    1. 45 points; 
    2. 43 points;
    3. the maximum score of 47 points;
    4. 44 points;
    5. 42 points.
    Are the sites valid according to the W3C validator.
    1. Valid XHTML Transitional;
    2. Not valid, 15 errors;
    3.  Valid XHTML Strict;
    4. Valid XHTML Transitional;
    5. Not valid, 16 errors;
    The best sites seems to be, and

    The next question is of course "How fast are these sites according to Pingdom tools?"
    1. 2.8 seconds / 0.8 seconds;
    2. 5.3 seconds / 5.1 seconds;
    3. 0.6 seconds, 1.7 seconds / 1.3 seconds;
    The speed of the Helenahoeve was 0.7 seconds. See also the Dutch page is slow, seems to use Flash. So is my favorite after

    How to improve Safe Browsing

    Remember my first post on this blog? It was about malware on the site. According to Google nowadays almost every website could be infected with malware, and I believe that that is true.

    As webmaster I want 2 things:
    1. That the site does not contain malware;
    2. That I do not link to a site containing malware.
    The second option seems to be the hardest, because I don't have control over the sites to which I link. So I thought, may be should I use Google's Safebrowsing website.

    With some help of Snoopy I created some PHP code to test if a specific website is suspicious. The idea is good, however the bottleneck is the response time. It takes more than 6 seconds to check 36 external links.

    See for example this Dutch testpage and be patient ;-) All external links where created with this PHP function:

    function showLink($naam, $titel, $url) {
      $snoopy = new Snoopy;
      $file = "".$url;
      $suspicious = stripos($snoopy->results,"Site is listed as suspicious");
      if ($suspicious == FALSE) {
        echo "normal external link";
      else {
        echo "warning";

    May be should I leave it to the browsers. When I try to visit the site with:
    1. Google Chrome - I get a safety alert
    2. Mozilla Firefox - I do not get a safety alert
    3. Mozilla Firefox with the Web Of Trust addon - I get a safety alert
    4. Safari (on a Mac) - I do not get a safety alert
    5. Internet Explorer 8 - I do not get a safety alert
    6. Opera - I do not get a safety alert
    So, I advice to start Safe Browsing now by using
    1. Google Chrome, or 
    2. Mozilla Firefox with the Web Of Trust addon 
    as your default browser. This despite the IE8 Smartscreen Filter ...

    Update 14 march 2010: There are also Web Of Trust addons for Internet Explorer and Google Chrome. So I advice to browse only with one of the following browsers with the WOT addon.
    1. Google Chrome
    2. Mozilla Firefox
    3. Internet Explorer
    Update 28 march 2010: Discovered that the site is not safe according to Google Chrome and to Mozilla Firefox. Browse safe. Use:
    1. Google Chrome with the WOT addon or
    2. Mozilla Firefox with the WOT addon.

    Google gives a warning, while WOT trust this site.

    Normal, large, larger and larger

    Just another test. How many times is it possible to increase the font-size before there appears a horizontal scrolbar. This time the test is in Firefox on a 1024x768 pixel monitor.
    1. 1x 'CTRL +' gives a horizontal scrollbar
    2. 4x 'CTRL +' gives a horizontal scrollbar
    3. After 8x 'CTRL +' (the maximum fontsize), there is still no horizontal scrollbar
    4. 5x 'CTRL +' gives a horizontal scrollbar
    5. 1x 'CTRL +' gives a horizontal scrollbar
    6. 1x 'CTRL +' gives a horizontal scrollbar
    7. 1x 'CTRL +' gives a horizontal scrollbar
    8. 1x 'CTRL +' gives a horizontal scrollbar
    9. 1x 'CTRL +' gives a horizontal scrollbar
    10. 2x 'CTRL +' gives a horizontal scrollbar
    This gives the following ranking for allowed font-size:
    Only did not get an horizontal scrollbar! That's great.

    Getting it all together

    The website is a great site which could be improved in the following ways:

    1. Ask for ratings on;
    2. Make the forms secure;
    1. Create a logical tab order through links, form controls, and objects by using the tabindex attribute;
    2. Provide keyboard shortcuts to important links (including those in client-side image maps), form controls, and groups of form controls by using the accesskey attribute;
    Update: According to the Dutch page the use of the accesskey attribute is not recommended.

    Usability of the forms
    1. Detect an error on a form as soon as possible;
    2. Let the user correct the error on the form directly;

    1. Try to improve the visibility in search engines as Bing and Yahoo.
    Thank you for following these tests.
