A recent survey conducted by 1and1 website hosting in one of their press releases said that websites were crucial to customers buying and retention decisions. This is quite evident in todays age where in earlier people used to have their telephone numbers on their visiting cards but now they have their website address on their visiting cards even if they dont have their telephone number. That surely shows a change when it comes to marketing!
I have written an article on why and who should have a website? I think this is another reason which maybe I missed in the articles.
