I have been wondering... are those $150, $300 ultra authority links I've been seeing sold really worth the money? I've tried virtually every linkbuilding strategy on the planet in my years of SEO, but the one thing I haven't been able to justify trying yet are those high end $$$$ authority links. Don't get me wrong... I've EARNED a few CNN-quality links in my days, but I still have yet to buy in. So what are your thoughts? What sort of value do those types of links hold? Obviously they are powerful, so I suppose my question would be this: From a dollar spend to rank gained perspective does it make sense to spend on high-dollar links? Is one $150/$300/etc link really as powerful as its price tag or is there a fair amount of salesmanship and hype?
