How relevant is the experience of working with link exchanges for an SEO specialist?

Question

Search Engine Optimization

Thanks to the guys from the toaster, I have little experience in promoting projects, but I have never used link exchanges, I considered them to be a kind of analogue of "traffic exchanges" where all the slag comes from, and even for money.
Can you comment or refute the opinion?
I wonder - are link exchanges relevant now, is it worth using them for large companies, or just at the start? Does it make sense to use the sensational automatic exchanges like Rookee to promote the site abroad, or do they make more sense for Russia?
Thanks a lot

Answer 1

Exchanges are irrelevant.
Neat, competent link building and crowd are relevant.
