I know that do-follow links are better for getting my website ranked higher in Google. However, my question is for external links - from my blog.
I write a blog and I include links to websites with high DA (above 70). I am doing this to show Google first of all that my content is related to this industry from the links, but also to establish high authority for my website.
So, should I use no follow or followed links? I heard that if I have lots of external links, the effect could be opposite.
