I am asking because there is a 6 year old domain (under new ownership with a new website as of this year) in my medium to high competition niche that has around 625k links blasting at the home page. 93% of the anchors are spread out between only 8 keywords. 2% is pointed at the main keyword, the rest is spread out between 8-9 misc keywords. The home page ranks #1 for the main keyword. This domain is not a buffer page, it is a real operating website. So how old does a domain have to be before I can blast 600k links at it? (btw, I understand I can?t blast 600k links all at once, I plan to drip the links over a 2 month period) Thanks guys for your time!
