I am doing a few SE Nuke blasts to diversify my backlink profile. Should I use broad match keywords or should I use long tail keywords. broad = dog collar long tail = dog collar for terriers Are the SE Nuke sites I submit to going to have any authority? Or is this just going to be useful for link diversification? If it is only good for diversification maybe I should not use any keywords. It is going to look funny if every link to my site has a keyword as anchor text. Maybe I should go generic keywords and raw URLs. Any recommendations?
