April 21, 2026
Expanded automation helps brands generate high-quality, audience-aligned prompts at scale, strengthening AI visibility analysis and enabling more precise optimization.
Semrush Enterprise today announced the release of Persona-Based Prompt Generation, new capabilities within its AI Optimization (AIO) solution that helps teams create high-quality prompts tailored to their brand, topics, and audience personas.
This new feature enables more realistic simulation of user queries across AI search platforms, enabling more accurate visibility tracking and tailoring brand messaging to how different audiences think, search, and decide.
Generate High-Volume, High-Relevance Prompts in Seconds
As the LLMs and user behavior continue to evolve, brands need reliable ways to approximate how their key audiences ask questions, so that they can track relevant prompts and refine messaging to better match these questions.
Persona-Based Prompt Generation fills this gap by creating informed prompts, helping teams improve project coverage and relevance while working within a volatile and rapidly shifting channel.
Teams simply input their brand, domain, and key topics, before adding additional audience characteristics like:
- Goals (e.g., research, compare options, get support, making purchase)
- Budget sensitivity (budget-conscious to premium-focused)
- Experience level (beginner to expert)
- Decision factors (price, quality, convenience, brand reputation)
This greatly reduces the manual effort required, while creating more accurate prompt sets. Brands can run more tailored analyses that support persona-driven content planning.
Overall businesses gain:
- Enhanced data quality for AI visibility assessments by expanding prompt coverage.
- Support for more realistic scenario testing, acknowledging that AI behavior varies and evolves.
- Accelerated setup, reducing hours of manual ideation to seconds.
- Projects stay aligned with brand positioning and real-world user motivations.
Supporting Strategy for Multiple Marketing Teams
Persona-Based Prompt Generation provides targeted advantages across teams:
- Brand & PR gain visibility into how different audiences ask about their brand or competitors in AI chatbots.
- Content receives ready-to-use question sets for AI-informed content planning, aligned with buyer journey stages.
- SEO gets scalable, intent-rich prompts to power more accurate AI search analysis.
By offering a unified prompt creation workflow, the feature supports cross-functional teams working to understand and influence how brands appear across AI-driven discovery channels.
A Starting Point for Tailored AI Visibility Strategies
Semrush Enterprise continues to lead AI search innovation. Persona-Based Prompt Generation is an important step toward enabling enterprises to build richer, more realistic AI visibility strategies while maintaining strategic grounding.
