Do your connections all need to be from DR? I can help you reach the 30,000 connection limit. I have reached it about 2 years ago. I’ve been on LinkedIn since it’s first year in 2006 and my tactics for reaching that number have been via testing out various network building tactics inside LinkedIn. While I have been on LinkedIn 12 years it took a little less than 2 years to build most of them. The problem with trying to reach 30,000 is that Linkedkn limits the amount of connection invites you can send so the challenge becomes how to reach 30,000 while working within those limits placed on users by LinkedIn. You won’t get 30,000 connections by sending 30,000 connection invites. Most of those invites will obviously not respond so the amount of connection invites that would need to be sent to reach 30,000 connections is exponentially greater than 30,000 and LinkedIn places invite limits on all users. I know how to max that out but at the same time it’s probably going to take a couple of years to reach 30,000 connections if you continuously work on your network until your goal is met. The alternative would be for your LinkedIn profile to go viral in which case it may happen to generate 30,000 connections but if going viral the profile would need to reach a significant amount of LinkedIn users.
