I have an ecommerce site that has an EXTREMELY diverse backlink profile that I've built up over the course of a few months to gain some general authority. Now I just paid to have it redesigned and am ready to start really going after some keywords. I wanted to know if it's okay to go hard for a specific keyword and build 20 - 30 exact match anchors in a row. This anchor that I'm preparing to blast currently doesn't even make up 4% of the anchor profile. I also have a TON of branded / generic anchors already in place. Do I have a license to blast the shit out of a single keyword or should I still keep mixing it up?
