Frequently Asked Questions

Ninjasell FAQ

How does the AI Listing Builder ensure my listings are optimized?

The AI doesn't operate in a vacuum. It performs real-time analysis of actual best-selling listings on Etsy within your specific product category. It identifies patterns in successful titles, extracts high-performing keyword tags, and replicates the descriptive styles that drive conversions. This means every listing is built with a foundation of proven, current market data, not generic templates or guesswork.

Is the trademark check completely reliable?

The built-in Trademark Check provides a fast and free initial scan against the United States Patent and Trademark Office (USPTO) database, which is a critical first line of defense against common infringements and potential Etsy takedowns. However, for absolute legal certainty, especially for major brands or complex designs, it is always recommended to consult with a legal professional, as the tool may not catch every possible conflict.

What happens when ReSpark revives one of my listings?

When a listing has zero sales for 90 days, ReSpark automatically triggers. It analyzes current Etsy search trends and high-intent keywords. The system then regenerates the listing's title and tags with this fresh, optimized data and republishes the listing on Etsy. This process gives the product a new algorithmic "push" and makes it relevant to current searches, often reviving its visibility and sales potential.

Can I control where my products are posted on Pinterest?

Yes, the Pinterest Auto-Poster is designed for strategic automation. You typically connect your Pinterest business account and select or create the high-traffic boards relevant to your niche (e.g., "Trendy Apparel Finds," "Cozy Home Decor"). Ninjasell then automatically publishes new product pins to these pre-selected boards with optimized descriptions, ensuring your marketing is targeted and hands-free.
