nofollow meta tag

Hi Fellows.
i need your help. is meta nofollow tag is bad?

 

Just to clear up a few things on the nomenclature, a nofollow is not actually a meta tag. nofollow is actually an attribute's value used by anchor tags. Example:
<a href='http://www.site.com' rel='nofollow'>. In this example 'a' is your tag, 'href' and 'rel' are attributes of 'a', and 'nofollow' is a value for the 'rel' attribute.

Now back to your question. rel attributes with nofollow tell search engines that this link should not be followed. In essence if you want to build your site's page rank you want backlinks pointing to your site. If all of the backlinks have rel='nofollow' you essentially have no backlinks. Note that I'm making a generalization, to get further info check out google's response https://support.google.com/webmasters/answer/96569?hl=en

 

Just to clarify, there IS a meta tag CONTENT value called nofollow for the "ROBOTS" name, setting it declares everything on the page as nofollow -- and since there's no way to say "follow" on a rel (there is NO SUCH THING as a "follow" value) that's why it's considered 'bad' by some.

<meta name="content" value="noindex, nofollow" />

Means the entire page should not be indexed by search engines or have ANY of it's links followed -- and that's why it's bad. I've never grasped why anyone would want a page not to be indexed; usually that treads into the same category as 'hiding' online pages from users, at which point why the **** do you have it online.

Nofollow an entire page? That just breaks spidering but worse, as there's no such thing as "index" or "follow" as values, you cannot EVER unset it for specific elements on the page. (just as a robots.txt trumps the markup too!)

REALLY both values should be used with an eyedropper, and the only legitimate places for it in the markup (as a rel or meta[content]) is in things like user comments and/or forum post signatures where someone might abuse the page by filling it with spam; sad part is MOST of what people use nofollow for isn't so much that as just being a total dick to other site owners.
