Social media post ideas: the complete library

Forty social media post ideas by pillar, what people stop for (survey data), the mix of value and promotion, evergreen and timely, and ideas per platform.

The short answer

Never start from a blank page. Pick a content pillar (teach, show the work, prove it, be a person), pick an idea from the list below, and make it in the format your platform rewards. Keep most posts useful or human and a minority promotional, mix evergreen posts with timely ones, and keep a swipe file of ideas as you come across them. Each platform’s own ideas guide, linked below, has twenty more made for it.

People stop for real people. In Signs.com’s survey of 1,000 US consumers, reported by Net Influencer in December 2025, customer testimonials were the content most watched for at least 10 seconds (35%), followed by personal stories (31%) and funny or relatable hooks (29%), and testimonials and reviews were the most likely to influence a purchase (52%).

Forty ideas, by pillar

Ten for each of the four pillars that suit nearly every account:

The right mix of value and promotion

A feed that only sells gets scrolled past. A common rule of thumb, often called the 80/20 rule, is that most posts, around four in five, should be useful or human, and about one in five should promote. Treat it as a guide, not a law: what matters is that every post gives the viewer something, even the promotional ones, such as a demo, a result or a clear offer.

Evergreen and timely

Evergreen posts (how-tos, stories, results) stay useful for months and can be batched and scheduled ahead. Timely posts (news, trends, seasons, what happened today) earn attention now and fade fast. Plan mostly evergreen posts so the calendar is never empty, and leave one or two slots a week for timely ones, so the feed still feels alive.

When you have nothing new to announce

Most weeks have no news, and that is when the pillars earn their keep. Teach something you already know, show the ordinary work, share a customer’s result, or answer a question from your comments. None of these needs an announcement, and they are often what people stop for: in the Signs.com survey, real people and personal stories held attention better than polished brand content.

Keep a swipe file

A swipe file is a running collection of ideas: posts by others you admire, questions customers ask, things you learn, phrases people use. Save them in one place as you find them, tag each by pillar, and pull from it when you plan the week. Never copy a post; use it to see a format or an angle, and make your own version.

Make it in the right format

The same idea earns differently by format. In Buffer’s 2026 engagement report, carousels earned the most on Instagram, document carousels on LinkedIn, images on Facebook, text on X, and video on TikTok, Pinterest, Threads and Bluesky. Make the idea once, then the version each platform rewards.

Ideas for each platform

Each platform has its own guide with twenty ideas made for how it ranks posts: Instagram, TikTok, YouTube, LinkedIn, Facebook, X, Pinterest, Threads and Bluesky. They are linked in the related reading below.

Questions

What should I post when I have no ideas?

Pick a pillar and an idea from the table: a common mistake and its fix, how something is made, a customer’s result, or why you started.

What is the 80/20 rule for social media?

A rule of thumb: about four in five posts should be useful or human, and about one in five promotional. Treat it as a guide, not a law.

What kind of posts get the most attention?

Posts about real people. In the Signs.com survey, testimonials were the content most watched for at least 10 seconds (35%), then personal stories (31%).

What is a content series?

A run of posts on one theme in a repeating format, such as “Tip Tuesday” or “part 1, part 2”. Series make ideas easier to find and give followers a reason to come back.

What is a swipe file?

A running collection of ideas, posts you admire, customer questions and phrases, saved in one place and used for inspiration, never copied.
