I started buying domains a few months ago from expireddomains and namejet etc. I have about 40 now, only about 4-5 really decent ones pa38-52, the rest are average pa15-25 but nothing special. I'm not interested in selling places in my network, its just for my own local seo stuff. When I bought these domains it took days and days finding them and most of the good ones were $400-$600 a pop. I've since learnt that the high pa/da ones are far more powerful than the others so that's what I will concentrate on from now on. So I'm curious, how do you guys start massive networks with high da/pa on all domains? Is it just a matter of spending allot of time and money or is there a secret to grabbing great domains for a good price? thanks!
