The Product Description Problem
If you run a Shopify store with more than 50 products, you know the pain. Each product needs a unique, compelling description for both SEO and conversions. Writing them manually takes 30-45 minutes each. For a 500-product catalog, that is 250+ hours of writing.
Most store owners give up and either use manufacturer descriptions (duplicate content that hurts SEO) or write thin, feature-only bullet points (low conversion). AI offers a realistic third option.
How AI Product Descriptions Work
Modern AI tools generate product descriptions by combining:
Product data -- Name, category, specifications, materials
Brand guidelines -- Voice, tone, target audience
SEO targets -- Keywords, search intent, competitor analysis
Ecommerce best practices -- Benefit-driven copy, objection handling, CTAs
The output is a first draft that you review and refine. The better the input data, the better the output.
The AI Product Description Workflow
Step 1: Prepare Your Product Data
AI produces better descriptions when you provide structured data:
| Field | Example | Why It Matters |
| Product name | CloudRunner Pro Running Shoe | Base identifier |
| Category | Women's Running Shoes | Context for language |
| Key features | Lightweight mesh, 8mm drop, 280g | Source material |
| Materials | Recycled polyester upper, EVA midsole | Accuracy |
| Target customer | Female runners, 25-45, mid-distance | Voice targeting |
| Key benefit | Comfortable for runs up to 15 miles | Lead with benefit |
| Price point | $129 | Positioning context |
Step 2: Set Your Brand Voice Guidelines
Define how your brand sounds:
Tone: Casual and friendly? Professional and authoritative? Luxurious and aspirational?
Vocabulary: Technical jargon or everyday language?
Perspective: First person ("we crafted"), second person ("you'll love"), or third person?
Sentence length: Short and punchy or flowing and descriptive?
Step 3: Generate Descriptions
Use an AI tool built for ecommerce. Generic AI tools can write product descriptions, but ecommerce-specific tools like Obsess AI understand catalog structures, Shopify formatting, and how to integrate product links naturally.
Try the product description generator for a quick test.
Step 4: Review and Edit
Never publish AI descriptions without review. Check for:
Accuracy -- Are specs, dimensions, and materials correct?
Brand voice -- Does it sound like your brand?
Claims -- Are any statements unsubstantiated or exaggerated?
Uniqueness -- Run a plagiarism check on the first few
SEO -- Is the target keyword included naturally?
Step 5: Publish and Monitor
After publishing, track:
Search impressions for product pages (Google Search Console)
Conversion rate changes (Shopify Analytics)
Bounce rate on product pages (Google Analytics)
AI vs. Manual: A Realistic Comparison
| Factor | Manual Writing | AI + Human Review |
| Time per description | 30-45 minutes | 3-5 minutes |
| Cost per description | $15-50 (freelancer) | $0.10-0.50 (tool cost) |
| Consistency | Varies by writer | Highly consistent |
| Brand voice | Strong (if writer is trained) | Good (with guidelines) |
| SEO optimization | Depends on writer skills | Built-in |
| Scalability | Limited by budget/time | Nearly unlimited |
| Accuracy | High (with product knowledge) | Requires review |

The sweet spot for most stores: use AI for the first draft, then spend 3-5 minutes per product adding personal touches and verifying accuracy.
Best Practices for AI Product Descriptions
Do:
Provide detailed product data -- The more context you give the AI, the better the output
Define your brand voice upfront -- Consistency matters across your entire catalog
Include target keywords -- Tell the AI which keywords to incorporate
Review every description -- Accuracy is your responsibility
A/B test -- Compare AI descriptions against your existing copy on key products
Do Not:
Publish without reading -- AI can hallucinate features or make inaccurate claims
Use the same prompt for every product -- Customize inputs by category
Ignore SEO -- Ensure each description targets a unique keyword
Forget about mobile -- Keep paragraphs short and use bullet points
Skip alt text -- Use the alt text generator for product images too
Scaling Across Your Catalog
Priority Order
