I am running a 7 tier project to create backlinks to links from FCS Networker (imported using the API). There are around 3000 links imported from FCS Networker, and 50 added daily.
I have set the number of threads to 400. I am using a purchased site list with 100000s of links.
1) How many proxies should I use for this? I have 10 proxies currently from buyproxies.com
2) Which indexing service should I use? I am using GSA Indexer already.
3) Should I also be using a captcha solver service? I'm already using GSA Captcha Breaker.
