This. I’m closing in on 2,000 connections. Some of them are people I’ve never met in real life. Others are. Anytime I meet someone new in a business setting, I take their card back and add them to my contacts, and I send them a LinkedIn invite. I’ll do the same for people on email threads — ie, I’m talking with Person A from a potential client on an email thread, she copies in Person B, and I’ll go and add Person B on LinkedIn. Not shy about it, and there’s no reason to be. So I think bottom line is expand your network to as many relevant people as you can.
I also pump out articles and other professional items I write and cross post them there. Often times nobody cares. Sometimes it stirs conversation or I get hits on it.
A few months ago I posted something that was related to my professional but kind of in a goofy personal way (dealt with something I found in my 100 year old house). It must have trended or something because it generates something like 40,000 views. (That’s probably not a lot for you, but a ton for me).
I just view it as a way to plant my name in the minds of people in my industry. Eventually my name comes up and someone is like “oh I think I know who that is.” As opposed to being a total stranger. A personal branding thing I guess, which is important in my field.
