3 Strategies for Viral Content
- The Hook: The first sentence must stop the scroll. Ask a question, state a surprising opinion, or share a surprising stat.
- The Story (PAS): Use the Problem-Agitation-Solution framework. Describe a pain point, make them feel it, then offer your solution.
- The Engagement: Don't just broadcast; start a conversation. Ask "What do you think?" or "How do you handle X?"

Frequently Asked Questions
How does the social media algorithm score posts?
Algorithms (especially on LinkedIn and X) prioritize **dwell time** (how long someone spends reading your post) and **early engagement** (likes and comments within the first 60 minutes). Our generator crafts structures with spacious line breaks to maximize readability time, along with engaging questions at the end to drive comments.
Why does the tool generate three variations?
A single post may not fit your specific focus perfectly. By providing three different angles (e.g. an informational take, a narrative story, and a punchy bulleted list), you have the flexibility to select the best structure or run A/B split tests on different channels.
How many hashtags should I include?
Hashtag rules vary by network. X (Twitter) performs best with 1-2 highly targeted hashtags. LinkedIn benefits from 3-5 industry tags, while Instagram allows up to 30, though 5-10 specific tags placed at the bottom of the caption is generally recommended to avoid visual clutter.
Are my business topics or product details logged?
Topic prompts, product details, and target keywords are sent to SimplyUtils's AI service. AI responses may be cached for up to seven days as described in the Privacy Policy.
