Our Verdict
For merchants concerned about long-term SEO and eager to be discovered by emerging AI search engines, Arc: llms.txt is the clear choice. Its automated `llms.txt` generation simplifies a complex technical task. Conversely, if the primary goal is to boost immediate sales and improve the on-site user experience, UR: Smart Sticky Button offers a more direct approach. The UR app suits stores seeking a simple, no-code solution to guide shoppers towards key conversion actions. However, the complete lack of reviews for UR: Smart Sticky Button compared to the positive feedback for Arc: llms.txt suggests a potentially riskier choice for merchants in 2026, warranting further investigation before commitment.
