Common Product Description Mistakes and How to Fix Them

Even experienced sellers sometimes publish product pages that underperform because of avoidable mistakes in the Product Description. For beginners, understanding common pitfalls and how to fix them accelerates learning and improves results quickly. Below are the most frequent errors, why they matter, and practical solutions you can apply today.

Mistake 1: Being vague or generic

Problem: Descriptions like “high-quality” or “best on the market” don’t tell buyers anything concrete. They create doubt and don’t differentiate your product.

Fix: Replace vague claims with specific features and outcomes. Instead of “high-quality,” say “100% organic cotton with reinforced seams that withstand 50 wash cycles.” Provide measurable or observable details.

Mistake 2: Overusing jargon or technical language

Problem: Technical terms can alienate customers who don’t understand them, while still failing to communicate value to experts.

Fix: Use plain language and add technical specs in a separate section for advanced buyers. For example, explain what a technical feature does for the user, then list the technical term and measurement in bullets.

Mistake 3: Listing features without benefits

Problem: Features alone (e.g., “12 MP camera”) tell customers what the product has but not why they should care.

Fix: Pair each important feature with a user benefit: “12 MP camera—capture crisp photos even in low light so your travel memories look great without extra editing.”

Mistake 4: Ignoring formatting and scannability

Problem: Large walls of text are intimidating and lead to skimming, not reading. Important details get missed.

Fix: Use a clear headline, short paragraphs, and bullet points for specs. Highlight the main benefit in the first sentence to capture attention immediately.

Mistake 5: Leaving out dimensions, materials, and compatibility

Problem: Missing critical specifications leads to wrong purchases and returns (e.g., “I didn’t realize it was too small for my tablet”).

Fix: Always include exact dimensions, weight, materials, power requirements, and compatibility lists where relevant. Visual size comparisons (e.g., “roughly the size of a paperback book”) help too.

Mistake 6: Not optimizing for search at all—or over-optimizing

Problem: Ignoring keywords reduces discoverability, while keyword stuffing harms readability and trust.

Fix: Research one or two high-intent keywords for each product and use them naturally in the headline and the first 100 words. Prioritize clarity and user experience over SEO tricks.

Mistake 7: Exaggerating or making unverified claims

Problem: Bold claims without proof (e.g., “guaranteed to cure pain”) can result in returns, complaints, or legal issues.

Fix: Back claims with evidence—spec sheets, certification badges, user testimonials, or measurable data. If a claim is subjective, phrase it as a user experience rather than an absolute guarantee.

Mistake 8: Failing to test or iterate

Problem: Assuming a single description is final prevents learning which messages resonate with customers.

Fix: A/B test different versions (short vs. long, benefit-led vs. feature-led). Use conversion and return data to refine product copy over time.

Mistake 9: Ignoring customer questions and reviews

Problem: Product pages that don’t address common questions cause friction and increase support workload.

Fix: Read customer reviews and Q&A to identify recurring concerns. Update the description to pre-answer those questions, and include an FAQ section on the product page if necessary.

Mistake 10: Not matching description to images and specifications

Problem: If images show a different color or accessory than described, customers get confused and may return items.

Fix: Ensure consistency across images, descriptions, and spec sheets. If multiple variants exist, list them clearly and label images accordingly.

Quick action checklist to fix common problems

• Replace vague adjectives with specific, measurable details.
• Start with a clear benefit-focused headline.
• Add a skimmable bullet list of key specs.
• Include dimensions, materials, compatibility, and care instructions.
• Use one or two natural keywords for search visibility.
• Add trust signals like warranty, certifications, or ratings.
• Test variations and use customer feedback to iterate.

Example of a poor vs. improved description

Poor: “Top-rated headphones — great sound, comfy.”

Improved: “UltraComfort Noise-Canceling Headphones — Immerse yourself in rich, balanced audio with active noise cancellation that reduces ambient sound by up to 30 dB. Memory-foam ear cushions and a 30-hour battery provide day-long comfort and listening. Includes carrying case and two-year warranty.”

Final note

Fixing the most common product description mistakes is largely about clarity, relevance, and trust. For beginners, focus on specific benefits, accurate facts, and simple formatting. Over time, use testing and customer feedback to refine descriptions so they work harder for your business and make shopping easier for your customers.
