Whether you’re a solo content creator or part of a larger team, you can now create scroll-stopping social captions in seconds, backed by SEO insights and optimized for engagement.
Here’s how to do it, step by step.
Step 1: Choose Your Platform and Content Goal
The Social Content AI Tool lets you instantly generate captions for:
- Instagram – great for visual storytelling, brand voice, and hashtags
- LinkedIn – for professional insights and thought leadership
- Twitter (X) – for short-form commentary, newsjacking, and engagement prompts
Simply select the platform you’re posting to and describe your content (e.g., a new blog post, product drop, behind-the-scenes clip).
Step 2: Set Your Tone and Style for Maximum Impact
Choose from preset tones like:
- Professional
- Witty
- Friendly
- Promotional
- Inspirational
This flexibility ensures your voice stays consistent across platforms, whether you’re a founder building a personal brand or a marketer representing a business.
Pro tip: Match tone to platform. Use a witty tone for Instagram, a professional one for LinkedIn, and conversational for Twitter.
Step 3: Let Semrush AI Do the Writing
Once your input and tone are selected, click generate, and within seconds, you’ll get multiple caption options tailored to your needs.
You’ll also get:
- Hashtag suggestions based on trending keywords
- Emoji recommendations (optional)
- Character-length adjustments for each platform
You can tweak the copy, copy-paste directly into your post scheduler, or use it as a creative jumpstart.
Step 4: Pair With Trending Audio or Themes (Especially on Instagram)
Once your caption is ready, match it with relevant trending audio or viral formats to boost reach. Use Instagram Reels or TikTok-friendly clips and pair your caption with high-performing sound for better discovery.
Example Use Case:
Let’s say you’re promoting a new blog post about AI for marketers:
- Instagram Caption: “AI isn’t the future of marketing, it’s the now. Here are 3 tools I used to 10x my content in a week. #AIMarketing #ContentTips”
