I had a new theory, after the new changes July 27th
www.example.com was my first domain created 1997
As I found it difficult to add new content to the old www.example.com, I created several theme oriented sub domains.
In German
a.example.com
b.example.com
n.example.com
r.example.com
p.example.com
w.example.com
On the main logo are 5 mouse overs and links to all other
theme oriented subdomains.
But no theme oriented sub domain had a link to
the old www.example.com
The old www.example.com has the same logo with
5 mouse overs and links.
But there are 6 theme oriented subdomains.
So I decided, that the most unimportant
theme orinted subdomain will be not linked from www.example.com
So www.example.com links on each of the around 400 pages to
a.example.com
b.example.com
n.example.com
p.example.com
w.example.com
but not to
r.example.com
r.example.com is the only subdomain with normal Google
All the other subdomains only receiving links, but not making links to www.example.com are filtered.
So I over worked July 28 the logo area.
Now are there 6 mouse overs and links to all other subdomains AND to www.example.com
Any ideas about this theory?
