Guys
I'm sorry. I'm probably either being a little dense here or I have not explained my predicament properly. I'm no techie, so excuse me and the following long explanation.
I've looked up 301 redirect and it suggests creating a .htaccess file with a line that points the old URL and file path to a new one. I don't have an actual file to point from or to other than the domain/index.html file.
I still don't understand why SEOMoz says I have duplicate content on TWO pages - xxx.co.uk and xxx.co.uk/index.html when I only have xxx.co.uk/index.html. I do not have any other home page for the website.
So, I guess I have a couple of questions:
1 - what line of code should be in my .htaccess file when I only have one file, not two.
2 - if I type xxx.co.uk into my browser's address bar, how does the browser know to take me to xxx.co.uk/index?
