I've done 2 link cleaning exercises and disavow requests so far but haven't removed those. I can see they are bad links but they're actually from decent, relevant sites in most instances which is why I haven't touched them yet.

What do you think is most damaging, run-of-site links or keyword link text?

So if you can't have too many nofollow links to upset Google, does Google respect the nofollow 100%?

I've been trying to recover from a Google algorithm change since Sep 2012, so far without success. I'm now wondering if the nofollow on external links in my blog posts are actually doing me damage. http://www.smartdatinguk.com/blog/

Does anyone have any experience of this?
