We use third party software on our website. Part of the license agreement means not modifying the copyright line. I have no intention of breaking this, however, because that line includes a dofollow link, the majority of our website links to a third party site.How can we best address the SEO impact of this (without modifying the link itself - which we are not allowed to do)? I know that we can set a meta tag to instruct Google not to follow any links, but that will probably hurt more than it helps by reducing internal links?
Nofollow without modifying the link itself
seo;nofollow
