Now we are separately hosted them, http://www.karinca.com.tr is hosted in a x firm. and http://www.karinca.net is hosted in y firm. http://www.karinca.net's pagerank is 5, and http://www.karinca.com.tr's page rank is 2, i want to close the http://www.karinca.com.tr site and i route it to http://www.karinca.net if i do it karinca.net's pagerank is increase or decrease? is it good for google pagerank and google listing.
It's better if you make a landing page in http://www.karinca.com.tr/ and drive traffic by link to your main domain. This is the best way if you want to get link & PR juice.
vegabond is right, just keep to "googles rules" and that doesnt include routing (if your purpose is PR).
If it makes more sense to just route them both to the domain then do it. I'd steer clear of anything underhanded.
how much data content should include the http://www.karinca.com.tr page. and how much second should the http://www.karinca.com.tr wait to redirect the http://www.karinca.net. is meta tags important on the http://www.karinca.com.tr page?
