Will AI-generated descriptions hurt my SEO ranking?+
No — Google's quality guidelines focus on helpfulness and originality, not the method of creation. AI descriptions that are accurate, unique, and genuinely helpful for the buyer perform well in search. The risk comes from mass-duplicated, low-quality content, which this tool avoids through platform-specific structuring and keyword diversity.
How many keywords should I target per product description?+
For most platforms, 1 primary keyword and 3–5 secondary keywords is optimal. Aim for a keyword density of 1.5–2.5%. Higher density triggers spam filters on Amazon and quality penalties on Google. This tool automatically calibrates density based on your selected platform's algorithm preferences.
What's the ideal product description length for Amazon vs Shopify?+
Amazon's A+ Content recommends 400–600 words for indexed descriptions, but the visible bullet section (5 bullets × 255 characters each) is most critical for conversions. Shopify descriptions perform best at 300–500 words for SEO, with the first 160 characters used as the meta description. Etsy allows up to 5,000 characters, and longer, keyword-rich descriptions tend to rank higher within Etsy search.
Can I use these descriptions on multiple platforms?+
Technically yes, but it's not recommended. Each platform has unique formatting requirements, keyword strategies, and buyer intent patterns. Shopify buyers are discovery-focused, Amazon buyers are comparison-focused, and Etsy buyers are story-focused. Use the platform toggle to generate tailored versions for each channel to avoid duplicate content issues and maximize conversion rates.
Is my product data private?+
Yes. KJSynthora does not log, store, or share any product information you enter. Your data is sent directly to the AI model and discarded after generation. We have no access to your product catalog, keywords, or generated descriptions.
