Yes, a nofollow is not as strong as a d0follow but a good contextual nofollow from a real site will still help.Just starting out getting some guest posts for a site so no need to balance out with do and nofollow.
Question is will I see any benefits with a nofollow link?
It depends on the site. If it's a quality site, it will benefit to yours.
DA/PA doesn't mean shit...I agree with it. It actually depends on the DA/PA of the sites.
