For merchants prioritizing a fully automated, AI-powered SEO solution with comprehensive features like tag generation, alt text creation, and description writing, and who are comfortable trusting a newer app, Lyros ‑ Smart SEO & Tags could be a valuable choice. Its custom prompt functionality allows for tailoring the AI's output to specific brand voices. However, SEO On: AEO optimizer LLMs.txt, due to its significantly higher number of reviews, likely has a larger user base, which could translate to more community support and a proven track record, particularly if AEO is a specific priority for the merchant.
