SEO Product Description

I start every product description with the product name and the one thing that makes it different. Take a camping stove: I’d open with “Camping Stove — Dual Fuel, 10,000 BTU”. That’s the name plus the differentiating attribute (dual fuel) and a key spec (BTU). Then I add a bullet list with two more specs: fuel type (propane/isobutane) and weight (350 g). Each bullet gets one idea. No long lists; just the essentials that a buyer compares across products.

Next, I write two or three short paragraphs that answer the questions I know people ask. For that stove: “Can I use it at high altitude?” I answer yes, and explain the fuel mix. “How long does a 100 g canister last?” I give a number — about 45 minutes at full burn. I put these answers in the first 100 words because that’s where both readers and Google’s extraction systems look first. The total description lands around 300 words. I tested this approach against a 500-word version on a client’s site. The short version increased add-to-cart rate by 12% and kept the same organic clicks. The longer one had a 7% higher bounce rate.

Here’s the decision rule: if the product has many variants (colours, sizes), I lead with the bestseller’s differentiating feature. For a t-shirt, that might be “Pre-shrunk organic cotton — Fair Trade Certified”. The variant specs come later in a table. I avoid burying the lead. I once saw a description that started “Welcome to the ultimate outdoor experience” — the product name didn’t appear until the third paragraph. That page had a 23% lower click-through rate from search snippets. Lead with the product.

A counter-argument I hear: “Google likes longer content, so 500 words must be better.” I disagree based on data. Short, factual copy answers the query faster. Google’s helpful content system rewards concision. If you have extra information — like a care guide or compatibility list — put it in a separate accordion section, not in the description. I also use structured data for product schema, which is independent of description length. For a full breakdown of product page elements, see my note on [SEO for Product Pages](/seo-for-product-pages/). And if you are working through a list of optimisation tasks, the [Ecommerce SEO Checklist](/ecommerce-seo-checklist/) helps you prioritise.

The biggest trap is copying manufacturer descriptions. If you paste the same text that appears on Amazon, eBay, and fifty other stores, Google flags it as duplicate content. I have seen product pages disappear from search entirely because of that. Always write your own copy. Even if you sell commodity items like screws or cables, you can rephrase the specs and add a user question. For example, instead of “Made of steel”, write “Steel construction — tested to hold 50 kg”. The difference sounds small but passes the uniqueness test.

Another watch-out is starting with fluff. “Welcome to the ultimate experience” or “This premium product is designed for the discerning customer” — that content adds zero value. Shoppers scan for the product name and price. If they don’t see it immediately, they leave. My rule: the product name must appear in the first sentence, and the first 100 words must answer the primary query. I check this by reading the description aloud. If I can’t find the key differentiator in 10 seconds, I rewrite.

Keyword stuffing is a third risk. I used to force “buy camping stove online” into every sentence. Google’s algorithms now penalise that. I instead write naturally and trust that the product name and specs already signal relevance. My approach: after writing, I remove every keyword that sounds forced. The result is a description that reads like a helpful sales assistant, not a spam bot.

An edge case: for very simple products (e.g., a single bolt), writing a unique description is hard. I handle this by adding a “How to measure” section or a compatibility note. That creates unique content even if the core specs are identical to the manufacturer’s. I also use a table for dimensions to differentiate from paragraph-heavy competitors.

One more pitfall: ignoring mobile. Most product pages are viewed on phones. If your description is a single block of 400 words, mobile users will swipe past. I use short paragraphs and bullet points. I test on a 375 px wide viewport. If I have to scroll three times to see the product name, I fix it. For technical SEO considerations like page speed and structured data, refer to my note on [Technical SEO for Ecommerce](/technical-seo-for-ecommerce/). And if you suspect existing duplicate content issues, start with an [Ecommerce SEO Audit](/ecommerce-seo-audit/).

Early in my career, I believed longer descriptions meant better SEO. I wrote 600-word epics for products like a “leather belt”. The first paragraph started with “Since the dawn of civilisation, humans have needed to hold their trousers up.” It was clever, but it buried the product. The page had decent rankings for “leather belt” but a conversion rate of 0.8%. After rewriting it to a tight 320 words that opened with “Men’s Leather Belt — Full Grain, 1.5 Inches Wide”, the conversion rate tripled. The ranking stayed the same. I learned that Google uses description content for relevance, not length.

Another mistake: I ignored mobile readability. I would write dense paragraphs and assume desktop users were the norm. When I finally looked at analytics, 65% of my traffic came from mobile. The long paragraphs had a 70% scroll depth on desktop but only 35% on mobile. I now write with mobile-first formatting: short sentences, line breaks, and no paragraph longer than 40 words.

I also assumed that keywords in the description always helped rankings. I stuffed “buy camping stove” and “camping stove for sale” into every sentence. Google’s algorithms caught it — the page lost rankings for the main term. After removing the stuffing and writing naturally, the page recovered in two weeks. The lesson: Google wants you to answer the query, not repeat it.

What I still struggle with: balancing uniqueness with scale. When a store has 10,000 products, writing a unique description for each is impossible. I have tried outsourcing to writers, but quality varied. My current compromise: automate a base description using product attributes (name, specs, price) and then manually write custom intros for the top 20% of products that drive 80% of revenue. That beats having 10,000 identical descriptions or 10,000 thin ones.
