Contextual links are of the highest value and impact.

You can do a contextual image link for example and use empty alt tag. Such link would have [EMPTY] anchor text.

You will be losing many opportunities for relevancy though. That is the whole point of lot of surrounding text and other on-page aspects when it comes to links. Text is the easiest for engines to understand.

Link can still index even with that little text around it. More text and relevancy makes it easier though.

d0follow or nofollow are <a> tag attributes. It's either set or not. You only need to set nofollow manual, by default link is always d0follow.

EXAMPLE:

Nofollow:

Code:

<a href="https://www.blackhatworld.com" rel="nofollow">Black Hat World</a>

D0follow:

Code:

<a href="https://www.blackhatworld.com">Black Hat World</a>

Not all backlinks are same. The contextual backlinks in high authority sites pass more authority and trust to your site.
