Spamming backlinks using GSA SER is very expensive due to the captcha costs (deathbycaptcha) even with Captcha breaker it is still very expensive as I spammed backlinks 24/7 with VPS (Hoststage) What is your method? to save money on captcha? I planning to only build backlinks only if the ranking drops from #1. What are your opinion? Only when my keyword ranking drops then only I will continue to build backlinks to it? Will this work? And I have been spamming a lot of links to tier 1, it seems to be wasting a lot of money than helping? From what I read is that tier 2 backlinks will help to increase the link juice and indexation of tier 1 backlinks, is this true?
