How to change all external links to No-Follow in Bulk?



Is there any way to change all external links to No-Follow ?
Is this good for seo/serp ?
Will doing this cause any issue ?

  1. By using nofollow links on all external links will not cause any problem at all.
  2. It will not either benifit in SEO, because nofollow link will sculpt your pagerank.

If you’re using wordpress then I think it’s possible via plugin.

I also use nofollow in my most of outbound links, but when it comes to higher authority sites like, then I don’t use nofollow attribute. Generally when too many sites link particular page without nofollow attribute then you should do the same, because that page will be consider as non-affliate page. And linking to non-affliate page gives you some trust score.
