I have some really nice tier 1 niche specific backlinks. I'm considering placing a PBN order from a really nice network to add three very strong tier 2 links to each tier 1. My question is should all three tier 2 links use the same exact match keywords as the t1? I will obviously be building more tier 2 links, but since these are high quality PBN links should I try to get the most bang for my buck; or would this leave too large of a footprint? T1 - 20 links - 10 exact match keywords T2 - 60 PBN links - 10 exact match keywords T2 - 240 web 2.0 blog post - mix of long tail, naked, and other niche relevant KWs T2 - 60 web 2.0 profiles - naked T2 - Mix of GSA links - naked, generic, and niche relevant Would something like this create enough diversity?
