How does google consider these links? for example :

<a href="url" rel="nofollow" rel="dofollow">text</a>

Is it a dofollow link or nofollow? Which one has more priority over the other one? I've used dofollow tags for backlinks of my website http://www.greenseo.ir , but I think it's an error!

No such thing as dofollow:

The dofollow attribute does NOT EXIST in either rel or meta, this is due to the fact that by default both pages and links are considered dofollow unless you use nofollow.

Meta follow is not to be confused with dofollow <meta name="robots" content="noindex, follow">

Despite MASS belief follow and dofollow have nothing in common other than the fact they share a similar name, it has absolutely no bearing on passing of page rank. Meta Follow it simply informs search engines to discover content on the receiving end of links...

A page that is not indexed by Google or Bing will not pass juice period. Also, the usage of content="noindex, follow" is pointless because simply using content="noindex" informs search engines to follow links unless you use content="noindex, nofollow".

Rel dofollow is invalid markup:


<a href="#" rel="dofollow">test</a>

Bad value dofollow for attribute rel on element a: The string dofollow is not a registered keyword.d.

Using duplicate REL is invalid markup:


<a href="#" rel="nofollow" rel="rel">test</a>

Error: Duplicate attribute rel.

Example of valid markup using multiple rel values:


<a href="#" rel="nofollow me">test</a>

Document checking completed. No errors or warnings to show.


The tag rel="dofollow" doesn't exist, it does nothing if anybody uses it.

Having two rel attributes in the same tag is an error, regardless of their value.

  • You can, however, have two rel values in the same tag, as long as you don't have more than one attribute, i.e. the following is valid: <a href='url' rel='nofollow noreferrer'>text</a>
