Scrapebox 2.0 can indeed harvest 1 million+ urls per minute from Google, as I show in this video.
Proxy service used - The service I used in this video has gone out of business, I list the latest and best back connect proxy service for scraping on this page (and I will continue to update it as things change) - http://scrapeboxfaq.com/scrapebox-pro...
Scrapebox 2.0 is exceeding efficient at harvesting from google and the other 20+ engines included with it. Engines like:
Google
Yahoo
Bing
AOL
DeeperWeb
Yandex
Youtube
Google Maps
etc...
Watch as I show scrapebox harvesting in excess of 16,667 urls per second with basic keywords. Scrapebox 2.0 works well with advanced operators and advanced searches as well.
