If I were to imply something like websites, could I also use "website (s)" or is it "website(s)" with no space between the word "website" and the "(s)" implying the plurality of website?

Basically, how do you use the (s) plurality indicator?

You would use no space in between.

However, you may want to consider the fact that it is more correct to write Web site(s). That is, instead of writing "website", write "Web site"; and instead of writing "website(s)", write "Web site(s)".

I thought it was rather strange when I first saw it in my e-business textbook, but look it up, you will see that it is true!!

websites would be the plural and be sure not to use website's unless you are talking about something that belongs to the website(ownership)

no space: website(s)

You can also use a forward slash: website/s

You would use it website(s) no space. you would use it in a article or quote when you belive there might be a plural but you are not positive.
