I am currently writing a report and I have been compiling a list of references (from IEEE mostly) and I also have a number of websites.

My question is, what is the best way to note a website URL? Would it be to reference and cite a URL, would it be adding a footnote? An example would be a reference to google.com. Would it be the correct to just create a footnote?

I've started to just add a footnote each time a website is mentioned (using LaTeX) so for example if a javascript plugin is mentioned then a footnote would be added to the website URL. How would be best to do this as it would not suffice as a reference as it is just noting a website for further reading. I do not have time to waste be writing the whole report to then have to go back through and edit the document hence my question.
