Hi! I made a new domainanalyzer website with bulk analyzer functions (on site seo, social counter, "builth with", and other helpful functions). And I have hundreds of millions of domain names... I upload 50-100K domains/day, but I must choose wisely domains from my list... What should I choose? Alexa top sites? High CPC keyword domains (insurance, attorney, forex, etc.)? Or other type of domains? I use just Adsense on my site. Thank you in advance for your answer.
