The site is in hosting. To it screwed my domain of 2nd level and another issued by the host, the "service" domain of 3rd level. The service was used until he bought his. Earned when working, register it in different search engines. Made an account on Google tools and Analytics. Put a counter.
For a time all was as it should. In the search results was the main domain.
But a few weeks later it was replaced by "backup". And only in Google. The others (Yahoo, Bing, Rambler) find the one you want.
In robot.txt there is an entry:
The title in the header is with an absolute link to the main domain.
Other links on the website relative.
Spoke with the tech support of the hosting provider through the Internet. What he found is somewhat contradictory.
Maybe advise the right way?
— wait until you stick together?
— edit robot.txt?
— kill the service domain?
— forwarding(if it is, then what)?
— the other?
UPD: IN the tools of Google was all three — osnovnoye, wwwhomepage, sluzhebnykh(And the service I added after he got out in the search results). The first thing I got there and climbed. So in the settings there is the option to choose "Primary domain" of only the first two options. Ie c www. Chosen without a www. When I go to setup utility, in the corresponding field there is a line: "the Primary domain — Just the domain root level"
