Your posts will appear here Enter a topic, pick your platform and post type, then hit Generate to create 5 unique posts. ## How to Write Social Media Posts That Actually Perform ### Start With a Scroll-Stopping Hook The first line of your post determines whether anyone reads the rest. On Instagram and Facebook, only the first 125 characters show before the "more" button. On X, you have 280 characters total. Lead with a bold claim, surprising stat, or direct question to stop the scroll. Our [Viral Hook Generator](https://posteverywhere.ai/tools/viral-hook-generator) can help you craft the perfect opening line. ### Optimize for Each Platform A great LinkedIn post looks nothing like a great TikTok caption. LinkedIn rewards professional storytelling and data-driven insights. TikTok favors casual, trend-aware language. Instagram performs best with a mix of value and visual storytelling. X demands concise, punchy takes. This generator tailors every post to your chosen platform's unique style and character limits. ### Include a Clear Call-to-Action Posts with CTAs get 2-3x more engagement than posts without them. Ask a question, invite comments, encourage saves, or direct people to your link. The best CTAs feel natural, not salesy. Match your CTA to your post type: educational posts ask for opinions, promotional posts drive clicks, and engagement posts spark debate. ### Use Hashtags Strategically Hashtag strategy varies dramatically by platform. Instagram posts perform best with 15-20 targeted hashtags mixing niche and broad terms. TikTok uses 3-5 trending hashtags. LinkedIn uses 3-5 industry-specific tags. X uses 1-2 at most. Threads doesn't use hashtags at all. Use our [Hashtag Generator](https://posteverywhere.ai/tools/hashtag-generator) for platform-specific suggestions. ### Post Consistently With a Scheduler The best content strategy fails without consistency. Using a [social media scheduler](https://posteverywhere.ai/social-media-scheduler) lets you batch-create content and schedule it across all platforms. PostEverywhere's [AI content generator](https://posteverywhere.ai/ai-content-generator) can even help you create an entire week of posts in minutes. ## How to Use the AI Social Media Post Generator 1 ### Enter your topic Type in your content topic -- from fitness to marketing, tech to personal finance -- anything you want to post about. 2 ### Choose platform and post type Select your target platform (Instagram, TikTok, LinkedIn, X, Facebook, or Threads) and post style (promotional, educational, storytelling, engagement, or announcement). 3 ### Generate and copy Get 5 unique, platform-optimized posts with hooks, CTAs, and hashtags.
