I'm looking at ways to improve the visibility of my site
http://www.swimshack.co.uk

I've submitted it to Google Sitemaps & have uploaded a sitemap.txt file to
my server listing all the page URLs. Have not got a clue if I've done it
right, because I'm not sure I fully understand it.. Do I have to submit all
the URLs for every page from the 'Add Site' command. Do I have to add the
verification text at the top of every page?

Thanks
Ian
