On personal, post about: a hobby, a big goal, how you guys make money, something you love.
Get cheerleaders.
On business, posts about results and case studies, no markety fluff.
On business, do seo articles, don't skip it.
Spend 20min a day commenting real stuff from personal profile.
Your engagement on other people's posts will bring more visibility to your profile than all of your posts.
Most people do one of the above and they do it bad.
If you did all of the above even for like a few weeks... I guarantee you'd be in a completely different spot. People really over complicate this stuff.
Make your profile speak to the audience you're trying to attract. Have you're featured sectioned filled out: a calendar, your best case study, and a lead magent. Website link near your headline.
Your about section should tell a story, not brag about your achievements or anything, tell a story.
Send 25 connections a day. Have 30 conversations per day (figure it out), spend 20min commenting, post whenever, message every single person who engages with your stuff a question - don't over think it.
The whoooooolllleeee point is turn attention into conversations. So take every opportunity to get a conversation going.
Pro tip: start all your conversations the same way and track the responses.
