Quick question on link building

Hey guys, I am ranking a website for a local business. I have a question:

If I create generic anchors, does it make a difference if I put it in local language? Or will it still rank if written in English?

Anchors on your keywords creates a big difference rather than generic anchors
and yes you should put it in english bcos its a common language everyone searches but as you said you're ranking for a local business putting anchors in your local language will help you distribute your anchor tags for both type of users.

If your site is in english then your anchors should be in english as well.
