Ratio to keep up? Between no-follow and dofollow links

[felu]

Is there any ratio that we should to keep up between no-follow and do-follow links? Any kind of suggestions will be much appreciated.

I have seen many webmasters to say that the ratio between no-follow to do-follow should be kept near 2:1. But personally I don't think that any ratio matters.

It depends but the more dofollow links you have the better since it does contribute in building traffic and help in having a good rank in search engine. For nofollow you can use social media channels.
