What is the 50/30/20 rule for social media?
The 50/30/20 rule is a content-mix heuristic: 50% of posts should be original/valuable content that positions you as an expert, 30% should be shared/curated content from others in your industry, 20% should be promotional. It's a starting rubric, not scripture. Many high-performing brands run pure 100% original, and many creator-led brands run heavier promotional mixes. The point is avoiding an all-promo feed that reads as spam.
This is a rule of thumb rather than a market statistic. Nothing in The Wall's vendor data measures it, so no figure is attached. The answer above is editorial.
Why this matters
Google puts this question in People Also Ask for the "social media marketing" query, which means buyers are asking it while they shop. The answer above is The Wall's editorial position. We index 3,460 verified US growth-services vendors across 10 pillars, and this particular question sits outside what that data can settle.
If you are evaluating vendors in this category, the Social Media Marketing pillar page carries the full US firm list with rate, team size and headquarters filters.
