Having 10.000 links build with 1 keyword ( example " dog training" ) will hurt your site and google will see this as unnatural link building .
The key for a succesfull linkbuilding campaign is Keyword Diversity .
I tend to setup my senuke campaigns with onlye 10-20% of my main keyword(s) set as anchor .
This has proven to be more succesfull and faster rankings for me and my clients .
Thats why i launched this new gig . Using my private software .
You will get a minimum of 200 related keywords to your main keyword . This can be 1000 keywords all depending your main keyword .
