How should I market evergreen content to increase traffic on my site?

Hi all,

My site is www.oldmandan.com and I have about 400-500 unique visitors with approx. 1000 page views per month.

I publish 4 products every week:

• Monday: Daily Learnings - 7 learnings from the past week on being healthy, wealthy or wise.
• Tuesday: Essay - approx. 2000 word article on thoughts or experiments I run on optimizing human performance
• Wednesday: Podcast episode for my career podcast - Accounted For
• Thursday: Book review of a past book I completed reading

My subscribers get a newsletter on Monday that includes all 4 items from the past week.

I have about 4-5 months worth of weekly content (60+ pieces all together) and I've only been sharing them each on the morning of the day I publish them. I share them on my personal FB page, Linkedin profile and medium (medium is more recent). Knowing only 5% of my social media audience tends to view posts I share I was read about recycling my "evergreen" content using platforms like Buffer or Hootsuite.

Is there a strategy that folks have found to be effective? (i.e. sharing same post twice a day at specific times or just rotating historic publications daily etc..)

Would love to hear your experience with content marketing with your blogs and get any feedback I can.
