Yesterday our position on some keywords dropped. Not a lot, but it dropped.
In checking things out, we noticed that google no longer points to www.domain.com for us, now (after many many years) they suddenly point to domain.com, with no subdomain.
So I have a few questions, hopefully somebody has answers, or at least opinions.
Could this be related? A couple of weeks ago I was working on a staging subdomain, looking in the logs and found google was crawling it. I don't know how google found this subdomain, but it did, so I put robots.txt disallow all.
Should I do anything specific? I am thinking to check httpd.conf and make sure the www.domain is first in the vhosts, so if google does crawl by ip, that it will get the right domain. Also, I am thinking to contact google. Are these good ideas?
Thanks for any help.
