Internet Security (Unit 9) – Security concerns
One area of advertising that is on the increase is context specific advertising, otherwise known as Online Behavioral Advertising. This relies on a search engine, or ad company, monitoring the search history of a visitor and displaying ads it believes would be of interest to that visitor. It works on the idea that a person visiting a car website is going to be more interested in an ad for motor oil than an ad for diapers. Issues have recently be raised however about whether such a system is an invasion of privacy and whether a ‘Do Not Follow’ law needs to be created to help combat such systems. I would recommend that we use context specific advertising as our target market is very specific as well, however as we do not wish to be associated with such grey areas of advertising we will need to be ensure that we only deal with reputable companies.

Internet Security (Unit 9) – Web browser compatibility
Another area of concern is the way different browsers, on different operating systems, display the same code. Internet Explorer 6 has a well earned reputation of being very difficult to work with in regards to accepting and displaying HTML code in the same way as other main stream browsers such as FireFox. Comparing page layouts in various formats is a requirement when building a site to ensure cross-browser compatibility. A large portion of potential customers could be lost if the layout does not function on the browser they are using.
Various testing sites exist that enable a designer to check pages without having to install multiple browsers or operating systems. I decided to use Adobe Browserlab to test out various pages to determine where possible issues would lie.
The browsers are known to interpret code in different ways and I expected to see different visual results, especially with earlier versions of Internet Explorer which are notorious for requiring code fixes to display sites satisfactorily. For example, it is known that Internet Explorer 6 has a problem displaying the transparent sections of PNG files. Because of this issue we have coded our golf cart tires site to take that into consideration and so it should display correctly. If it displays anything incorrectly it will be because we had missed it as an potential problem.
I checked out my blog page and the golf cart home page in the following browser and system combinations:
- IE 6 – Windows
- IE 7 – Windows
- IE 8 – Windows
- IE 9 – Windows
- Safari 5.0 – OS X
- Firefox 5.0 – Windows
- Chrome 13.0 – Windows
I recorded any difference in layout, alignment, graphical display that appeared in each test.
The results of the testing were as follows:
All browsers, except IE6, display the blog page the same way. The main blog article on the left hand side, the profile section on the right, with the graphic on the main page overlapping the right hand column if the page size is shrunk. This was the expected result. IE6 however forced the left hand column to be the width of the graphic regardless of page size, which then forced the right hand column to display underneath the main blog post as it could not fit to the right if the page was shrunk.
Golf Cart Tires home page:
Because we had tried to take IE6 issues into account when we originally designed the site there was very little difference between the various browsers and systems we tested. However, there still was a slight difference under the IE6 testing in that it showed a top border to the page that did not exist in any of the browser displays.
As expected, these results show that IE6 compatibility is a difficult thing to achieve. However, IE6 is several generations old now and a decision has to made when designing a site as to whether to try to ensure total compatibility, and thus compromise on design, or to ignore IE6 as it is used by a increasingly small percentage of visitor browsers.
This form of compatibility testing should be used before the site goes live and before any future changes go live as well.
