I think that web personlisation is a very useful tool that helps customers and users alike, feel more comfortable online and gain a more pleasurable experience when visiting said websites. Essential it would be akin to a customer walking into a shop, to find only the things that interest him/her, i.e. websites such as Amazon use this capability alot, when a user visits the website, Amazon presents products that the user would be interested in. Not only can amazon choose which products can be displayed, but websites alike to amazon, have the option of letting the customer decide which products will be displayed when they log onto the website. This will result in a more enjoyable visit (and possibly more profitable in the case of selling products orientated toward the customer).
One of the methods Amazon uses is ‘Collaborative Filtering’. Amazon recommends products to customers by categorizing products into groups and having a similarity drawn between them. When a customer searches for a product, they can veiw said products, but will also be shown what other products people have purchased after they purchased the very product the customer is searching for.
Maybe 9 times out of 10 the suggested product would be related to the product initially searched for, but sometimes an unrealted product could be shown.
Another method is content based filtering. Amazon also uses this method, i.e. a user will be shown products related to that of which they have previously purchased in the past. So if a customer has a history of buying horror novels, then amazon will, obviously, suggest the latest horror novels to the user. It will not only just interest the user, but will also help sales on Amazons side
Obviously there are advantages and disadvantages web personalization.
- Having a customized and personalized view of a website will obviously create a more productive session for the user
- The customized product placement toward the customer will result in higher sales
- Personalization is more effecient
