Can nofollow links help with SEO?
If you have lots of links to your site and all of them are dofollow, then this may be considered as a suspicious sign. Most social media sites, including Facebook and Twitter also add nofollow to all outgoing links, however Google has an algorithm that takes social media signals into account, therefore these links will still benefit your site.
SEO is also a means to an end and the end goal is gain more traffic to your site and generate sales. Having an interesting blog article on a major news portal, or a video on a popular, related website, for example, will still draw traffic to your site, therefore these links can be very useful, even if search engines ignore them.
When looking at SEO it's always worth taking the long-term perspective into account and if you attract visitors to your site and your site has quality content worth linking to, it's also likely that some of the visitors to your site will in turn link to it, like or share your blog posts, etc.
So the short answer is yes, nofollow links still help your SEO, provided that it's somewhere people will see it and click it.
