hey, i havent noticed that yahoo counts also the no follow links in their link count list. (for example, a link from a comment on a blog with nofollow tag.) so having some no-follow links will also help me ranking on yahoo search engine marketing? or they dont matter?
just don't care about it much even google and msn dismiss that TAG look: "Google announced in early 2005 that hyperlinks with rel="nofollow" attribute[5] would not influence the link target's PageRank. In addition, the Yahoo and MSN search engines also respect this tag" quote from wikipedia
That is incorrect. Yahoo does give you link juice (and eventually better SERPS) from nofollow links - from my experience and site explorer.
yes, in site explorer i have nofollow links. for example, wikipedia no follow links appears in some sites that i have been exploring with yahoo site explorer. So, a nofollow link goes also on yahoo link count if im correct.
site-explorer, wikipedia blabla.yes site-explorer shows no-follow links,so does google webmaster center.Counting is a different thing, value is different.And wikipedia is a human-edited resource.Did yahoo engineers make that page?NO.And better pr does not mean better SERP.
PR is something Google uses, Yahoo may have a different parameter. Also, even if the nofollow link doesn't pass any "link juice", the search engines can still use the anchor text to get information about the content of the page, and this could indirectly affect its search rankings.
This is from Wikipedia about nofollow, which I think is correct. While all engines that support the attribute exclude links that use the attribute from their ranking calculation, the details about the exact interpretation of the attribute vary from search engine to search engine.[7][8] * Google takes "nofollow" literally and does not "follow" the link at all. That is supposedly their official statement, but experiments conducted by SEOs show conflicting results. They show instead that Google does follow the link, but does not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page).[8] Links with NOFOLLOW are included in the back-links reporting data at Google's Webmaster Central.[9] * Yahoo! "follows it", but excludes it from their ranking calculation. * MSN Search respects "nofollow" as regards not counting the link in their ranking, but it is not proven whether or not MSN follows the link. * Ask.com does not use the attribute for anything.
I have speculated for a while now that Google/Yahoo may count some nofollow links. It seems almost like the links do not effect the site that they are on, but they still effect the site they are linking to in some situations. Maybe, nofollow links are associated with some sort of trust ranking. If the site being linked to is trust-able, the links count, if it's new or questionable they don't. I've seen this a few times with Wikipedia since the links were nofollowed. There was an immediate boost after a link was added even though it had nofollow attached to it. When the link was removed, the ranking went down.
