So it's been said that Google is cracking down on link sculpting. What determines good link sculpting vs bad link sculpting? For instance, let's say I have a call to action on my web page that says "Learn More" and links to an inner page. On the same page I have a rich text link that does the same thing, let's say "white hat SEO". Would I be in the wrong to no follow the "learn more" CTA in this situation? I guess what I'm trying to figure out is, what is considered abuse vs just being smart about internal link structure?
