Three great providers of fast exclusive proxies are ScrapeBoxProxy.com, YourPrivateProxy.com and IPFreelyProxies.net who I’ve had proxies with both since 2010, they support ScrapeBox and i highly recommend either based on my time using their services. They offer “Exclusive” proxies, which are a little more expensive but far more reliable and faster than shared proxies because you are the only person using the proxies you are given. They make a huge difference in terms of speed and success rates compared to free proxies.
This means with less proxies, you can typically harvest more URL’s from Google, perform more PageRank lookups or Indexed Page Checks than you can with shared. Also the proxies will generally be a lot faster with all tool operations including commenting due to less users accessing the server.
I find a 10 IP package is ideal for normal use, or their 20 IP package for heavier use.
For ScrapeBoxProxy.com you can also use the coupon code SBPROXIES to get a 25% recurring discount off the advertised price of the proxies which makes them quite affordable.
Also ProxyGo is a provider of “free” proxies, however he scans many thousands of proxies every day and provides lists of the working proxies. As anyone who has scanned lists of free proxies knows, it’s a very time consuming and bandwidth intensive task filtering out the dead proxies to compile a working list. So for a one time membership fee for access to daily lists of scanned/filtered proxies, it’s an affordable alternative to exclusive private proxies without a monthly fee.
Please note ProxyBonanza and PacketFlip do “not” support the use of ScrapeBox with their proxies and they are not a viable provider for running ScrapeBox.
