I run a small SEO company and when signing up new clients we often find that their websites will have duplicate content or two home pages for example www.mysite.co.uk www.mysite.co.uk/index.html Obviously this essentially cuts the link authority in half and the website's SERPS suffer dramatically. Basically we use the <link rel="canonical" href="http://www.mysite.co.uk" /> protocol to let spiders know which page is the homepage it should take note of. Google also mentions using a 301 to the relevant resource from the duplicate content is necessary to re-enforce this. Is it better to 301 the "/index.html" page to the normal ".co.uk" page or the other way round? Or does it really not matter at all? Hope this makes sense, please let me know cheers.
