I need some explanation about my question.
Example on my header already added
<meta name="robots" content="noindex, nofollow" />
Should I add canonical tag again to my header?
<link rel=”canonical” href=”http://www.example.com/product.php?item=big-fish” />
Let me know :)
Update
we know canonical tag is currently also supported by google, yahoo and live search. How about noindex and nofollow? yahoo and live (bing) supported too?
Google, Yahoo!, and Bing (Live) support noindex
and nofollow
in the meta directives.
noindex
tells the search engines to not bother caching your page for inclusion in their results.
nofollow
tells them that you don't want any of the links on the page to be followed.
Adding the canonical
tag on the same page won't hurt, but effects are unknown unless you talk with one of the search engineers.
