Recently Yahoo has indexed many of my pages that have the no index no follow in the robots.txt file. These are all different landing pages that may be considered duplicate content which is why they were set up no index no file. Does Yahoo ignore this command? It doesn't make any sense to me.
what exactly did you put in the robots file?....the no index and no follow belongs in the meta tags. you use dissalow in the robots file
YES! I have experimented that if you use "nofollow" in url. Yahoo! slurp will ignore it and index your pages.
Yes. I thought that belong to meta tags too. And I guess yahoo ignore this comment as I saw backlinks from SB sites and wiki to my sites.
even google indexes links and pages from nofollow attribute, but then how much weight they give on those no follow links is yet unknown!
I read an article at SE Roundtable and as far as I can recall either MSN or Yahoo paid attention to the nofollow url tag. As for meta nofollow or disallow I agree with seo ranter - check out how and where you tagged it.
That's been the thing I've found interesting about nofollow links, the name implies that the spiders won't follow them, however, that hasn't been the case. While it doesn't appear (in my own testing at least) that Google gives them any weight, Yahoo certain seems to. I've noticed that when I tested blog commenting as a way to promote a site, my Yahoo & MSN traffic jumped up.
nofollow tag has no meaning for yahoo not. if there are pages that you dont want to be crawled by bots, you must add this pages to your robotx.txt
