I have a website served on the following URL : "http://www.plugimmo.com" which is a custom domain served by Google App Engine on the following URL : http://plugimmo.appspot.com

Since a while I have tried to optimise the Google indexing and ranking with no success. The problem is that searching on Google the keywords in the title of my home page does not retrieve my website at all even not in the 1,000 first results :

When checking the cached version of google ( cache:www.plugimmo.com), it says that the cached version is the one of 20-Aug-12 of "plugimmo.appspot.com". It looks there are several issues :

1 - The cached version is really old. I have made a lot of changes since the 20-Aug-12 and I saw the googlebot crawling my site several times.

2 - The cached version is for "plugimmo.appspot.com"

3 - When looking at the Google Webmaster tools, I see that the number of pages indexed for www.plugimmo.com is 0, but that can't be the case given the number of changes I made since then.

My questions would therefore be the following :

• Why is the version of the cache so old although I saw the googlebot crawling the site many times since 20-Aug-12 ?
• Is there a problem with indexing a custom domain served by Google App Engine ?
• Why is the Google Webmaster tools showing 0 pages indexed although new pages have been crawled and that no errors have been reported in the indexing ?

Also, the site has been developed with Google Web Toolkit. I have followed the guidelines regarding crawling Ajax sites. The home page when crawled by a robot is redirected to http://www.plugimmo.com/HomeSnapshot.html

Thanks a lot for your help !
