On my site I have pages like this /a-b-c.php .The problem is the spiders index my page in this way /a-b-c%0D%0A.php Can someone tell me what is %0D%0A?
Problem solved. I forgot to close a href in my code and I think that was the problem. Strange was that only yahoo bot doing that,google bot was indexing correct. Thanks all for your help.
