Hi Nofollow is an HTML attribute which is used to instruct some search engines that a hyperlink should not influence the link target's ranking in the search engine's index. It is intended to reduce the effectiveness of certain types of search engine spam, thereby improving the quality of search engine results and preventing spamming from occurring. Nofollow is usually use to prevent link juice being passed, so if the internal page does not won't link juice its can have the nofollow attribute eg â€register here†or “sign in†links. Regards Amit
hi no follow links are only provide traffic, but no link juice, one can use no follow link for internal pages, but do-follow are better because it provide link juice and the traffic as well.
If we use dofollow attribute for external links on our website, then our page rank will also share with other website, also google consider it as paid link buildings, and so that it will penalizes the website. Regards Amit
