Facebook's "Like This" Feature - Time & Effort required to integrate with an existing e-commerce site?

Question

How much time, and what basic steps, are involved in integrating the Facebook's "Like This" feature into an existing e-commerce site?

Let's say we are only interested in the feature at the product details level and have approximately 5 different product details areas.

Any recommended tutorials perhaps?

Thanks

Do you mean the Facebook feature where users can 'like' external pages? If so...

I'd recommend having a look at Add This rather than your own implementation which could take a while to work out - they offer a simple copy and paste javascript snippet that will add Facebook like functionality as well as other social bookmarking options for each of your product pages. They also allow you to track products being bookmarked and track click backs from user bookmarking.

If you mean your own custom feature for your site for users to 'like' products and then highlight them on a feed / homepage, then you'll need to track these 'likes' from users in a database and display them on the relevant page. The amount of time this sort of feature will take to develop really depends how far you want to take it. Obviously Facebook's featureset is massive and I wouldn't imagine you'd want to turn your ecommerce site into too much of a social networking site... hence my guess that you mean something like Add This?

It really couldn't get much easier. Throw facebook's js in the header, and drop a <fb:like> tag in. Or, there's a <iframe> based solution that doesn't require a js include.

Examples of both are available via facebook's code generator. Basic implementation should take under an hour. If you go all out, it might take a day at the outside.
