Hi,
Thanks for your reply - the problem is my main
website hosting (account name) isn't a proper web site hosting as such. I set it up with the aim of eventually making it a content-driven web site hosting but it's currently just a holding page. Meanwhile I've kicked on and set up several addon domains under the main domain which have plenty of content etc and are starting to fare well in the search engines. So when your say: 'Google will either not display content of your addon domains in search results, or it will give them low priority in comparison to the main
website hosting' ....that's the worse case scenario for me and the last thing I want. As it is, Google and Yahoo are showing plenty of content from the addon domains in search results - but does my original question mean they could be showing even more. I'd be quite happy for Google to never go anywhere near the main domain as it's effectively just a holding page with no content other than links to the addon domains on it.
