GSA SER as a stand alone tool with 30 dedicated proxies Captcha breaker and Scrape box scraping/SER search engine scraping is inefficient to pull off 7k links per day. At max it gets around 100-150 verified links per day, regardless of what settings are applied, and this goes for very optimistic settings with all the filters disabled, all languages, all regions, no OBL restrictions and all the contextual engines that are somewhat worth building backlinks on. Research was done reading through countless discussion on forums and guides testing lot of different settings. SO the tool-set goes as followed, broken down for easier sightseeing. GOAL : at least 5 k verified links per day for parasite link building - 30 dedicated proxies - CB - Scraped lists with SB and also tried GSA scraping. (2 000 000 sites daily from scrapebox harvesting using all GSA engine footprints) - Dedicated PC, great internet speed (400 Mbit/s) - variable thread count and no limitations from PC performance Now I face the dilemma, keep testing more and get the results eventually or buying sitelists is the only option.
