OK. Pardon my non-diplomatic language, but you have lots of errors.
Seems you did wrong on the SEO part, and wrong on the webmastering part.
1 - The link to http://www.1300truair.com.au/ does work fine.
So any index that would point to the right address would find its happiness there.
BUT it seems you NEVER indexed this site directly, just thru your own site...
2 - What I would do:
a - take care that if someone links to the "old" address, they are rerouted to the good one. Edit .htaccess file in the directory of the site, presumably /1300truair.com.au/ under your /public_html/.
I would personnally place the following:
RewriteEngine On
RewriteCond %{HTTP_HOST} rdpersonalisedprinting.com [NC]
RewriteCond %{HTTP_HOST} ^www.1300truair.com.au [NC]
RewriteRule ^(.*)$ http://1300truair.com.au/$1 [L,R=301]
(the line ^www contributes to the fact that all pages will be displayed as //1300 rather than some as //1300 and the others as //www.1300, not very good for seo; as an alternative, remove www. from ^www and place it on the last line //www.1300)
Expected result:
- all pages that are currently in search engines as rdpersonalisedprinting, will be silently redirected to the correct page; initially just in the visitor browser (search engines will still have the old address), then also on the search engines as their spider take note that the page is code 301, ie "moved permanently".
2 - Create an xml sitemap of the site at the correct address, eg by using gsitecrawler. Place the sitemap in the root of 1300truair eg as sitemap.xml
Also create at the same place a robots.txt file, with the following content:
User-Agent: *
Disallow:
Sitemap: http://1300truair.com.au/sitemap.xml
This will help all major serach engine to discover your sitemap.
3 - To speed up the indexing process, submit to Bing and Yahoo. For Google, you need first to have a page that links to your site... the 301 redirect might help but you should really consider to have some other page pointing to the "new" good page.
4 - You should have a site for your own use, in which you present your business and place links to your clients. This is not the case, since http://www.rdpersonalisedprinting.com/ does not qualify (for your safety, URGENTLY place an index.htm or index.php there!!!)
You also have a very serious potential security breach, but I'll PM you on that.
