Evaluation of Tesco's Website and a comparision with Asda.

Tesco’s target audience. Figure one shows how many graphics a page contains on Tesco’s website so you can understand here how some users may have problems with loading the website. Tesco could resolve this issue by adding a version of their website that doesn’t have any graphics so that 56k users wouldn’t have a problem browsing the site.The website has a vast amount of products and the information about each product is great, they give a detailed description of most of the products. Figure two is a screenshot of a product they sell and the description to go with it so you can see the amount of effort the Tesco team have put in so the customers don’t have to look else where for extra information. Tesco’s was the first website to offer users price comparisons with other stores. For example, type ‘ketchup’ into the Price Checker feature, and the site will return a list of prices for ketchup stocked in Morrisons, Asda and Sainsbury’s with Tesco prices listed alongside.To try and keep you coming back to Tesco, Tesco’s store information about you and what you have bought from them in a database so they can target you with special offers on the products that you are interested in. This is all done securely with encrypted data so nobody else will be able to read it. This is one method they use, there are other methods like online surveys so they can see what the customers really think of there website. With this feedback they can change the website and make it even better for the customer’s ease of use.I am now going to analyse www.tesco.com interms of affordability, visibility and feedback and compare it with www.asda.com The Tesco website shows good affordance because it is easy to interpret and understand the layout of the website and the links within it.The main headings are highlighted with a blue background to emphasise the title.The sub headings are arranged under each heading, all relevant topics are grouped together, making it easier for users to interact with the website. The visibility of the website is easy to see and understand as all menus are clearly identified at the top of the website. The categories are shown clearly with images to help understand the visible links on the site with subtle colours for ease of use.The navigation of the site is of good standard feedback is offered to the user, when buttons are clicked, no errors are found and the site is easy to browse and understand due to the good design of the system. Relevant information is provided to the user, ensuring good feedback is initiated.ASDA’s website shown below isn’t as well designed as TESCO’s website, it is harder to understand as it is very cluttered and there is too much going on, on one page. By looking at TESCO’s website ASDA could improve their own, by having a better structure to the site and by making titles and headings more clear for ease of use. This can be done by changing the style, font, colour and size of writing.  The feedback also isn’t as good as TESCO the pages don’t always link together properly or at all, and error messages are shown which says ‘no page exists in this location’.  However ASDA’s website has a good usability in terms of its registration facility, which saves regular customers' time by storing their details and not requesting it for subsequent visits. The search provided is also useful and provides alternative search terms in case no result is found. Overall the Tesco’s website has been designed better than ASDA for ease of use especially for first time shoppers. As they can benefit from the online shopping guides that take you through various processes such as using the shopping basket and navigating the tool bar. Also Tesco’s give the best product information, more detailed descriptions than any other online supermarket store. Tesco have integrated all the necessary features so the website runs well and products and services are advertised clearly. But TESCO could learn from ASDA by investing in a more advanced search facility to enable the specification of more characteristics about products.
