When trying with Scrapebox to harvest URL's for any keyword Google doesn't return any results allthough i use always Public proxies . Only Yahho & Bing returns harvested URL's for me . Is there any reason for this ? Has google banned me ?
Your proxies could be banned, go to harvest new proxies, test them, and then run again. When you first go harvest, watch the "connections" beside "Google" and see if it just counts down the number of connections really fast. Check your number of connections under settings for the google harvester. I usually set it @ 100 connections. Also make sure Google has a check mark on it under select engines and proxies.
Check if you have unselected Google from your harvester... It's just above proxies box... You will see search engines over there... If this is not the case you may have proxies which are banned so you need new list of proxies... Also check if your computer got any cookies, better to clear them...
I'm having the same problem. It used to work and at some point it stopped. I use other programs with the same proxies with no problems
