Writing tips
What a good product description includes
Shoppers can't pick the product up, so the description has to answer their questions. These four habits cover most of them.
Opening
Lead with who it's for
Say what the product is and who it suits in the first sentence. The title is already on the page, so don't open by repeating it.
Detail
Swap claims for facts
Words like "high quality" or "the best" say little on their own. A material, a measurement or a result is far more convincing.
Structure
Make it easy to scan
Most shoppers skim on a phone. Put features and details in short bullet points under a line or two of copy.
AI search
Answer the obvious questions
Materials, size, how to use it and who it's for are what shoppers and AI assistants look for. If they're missing, there's nothing to quote.
FAQ
Product description questions
How long should a product description be?
Most products need 120 to 300 words: enough to cover the main benefit and the key details. Simple products can be shorter and technical ones longer, as long as the text is easy to scan.
Can I paste the HTML from Shopify?
Yes. Copy the description from Shopify's code view or straight from your product page. The checker reads bullet points and headings from the HTML and ignores the code itself.
What does the reading ease score mean?
It's the Flesch reading ease score, where higher means easier. Around 60 or above reads comfortably for most shoppers. Shorter sentences and everyday words raise it.
Does description length affect SEO?
Length on its own isn't a ranking factor, but thin or copied descriptions give Google and AI assistants little to understand or quote. A useful, original description helps a product page rank and sell.
Is anything I paste stored?
No. The checker runs entirely in your browser, so nothing you paste is sent to Cape Wired or anyone else.
