Help in Internal Links

[Obbserv]

Which link attribute should be given to internal links of website?

Do follow or No follow  and why?

Hi Ravi,

Always use a Do follow attribute. Only in rare cases were you don't want pages indexed you could consider adding a nofollow tag but beside that, always use a Do follow.

Why: Do follow links pass PageRank and help your website score better in search engines. If you use a nofollow link your links won’t pass any PageRank and besides the homepage, your website won’t score with any pages.

There was a time people tried using nofollow tags to “sculp” there PageRank flow to help specific pages rank better. This practice doesn’t work since a nofollow tag won’t increase the PageRank flow to other Do follow links on your website.

Basically you can see a nofollow tag as a big PageRank eating black whole. You don’t want to throw your PageRank in it

I hope this helps!

Completely agree with Bob. The only exception where you might consider using nofollow on internal links would be on links for sign in, add to shopping cart,... - although they indicate that it's not really necessary.
Quote from webmaster tools on reasons why you could use no follow: (source:https://support.google.com/webmasters/answer/96569?hl=en)

• Crawl prioritization: Search engine robots can't sign in or register as a member on your forum, so there's no reason to invite Googlebot to follow "register here" or "sign in" links. Using nofollow on these links enables Googlebot to crawl other pages you'd prefer to see in Google's index. However, a solid information architecture — intuitive navigation, user- and search-engine-friendly URLs, and so on — is likely to be a far more productive use of resources than focusing on crawl prioritization via nofollowed links.
