When I go on Google (normal search in my browser), if I use too many operators like intitle, inurl etc. in a short amount of time, they basically block me from searching. If I search a lot WITHOUT operators it's fine. Now I'm thinking about my Scrapebox harvests, where I have had big keyword lists, say 100,000 , and a few hundred proxies, yet a lot of the keywords have come back red, i.e. incomplete. When I'm in my browser, Google allows me about 20 searches with operators, before it shuts me off. Therefore to keep harvesting ok I would have to have 5000 proxies assuming they all were live and none of them died in the process. My question is, how do you get around these limits? And if it is not possible for large keyword lists, do you just use Yahoo instead? How much heavy usage do they allow, compared to Google? I heard some people don't even bother using proxies when harvesting from Yahoo but I'd like to get your input on it.
