The verdict in three sentences
A good product description sells to a human and ranks for Google, without choosing between the two. The sweet spot is 150 to 300 words, with the keyword in the H1 and the first 100 words, benefits in bullets and Product schema markup. Rewriting manufacturer text into unique copy gains about 25% organic traffic and 14% conversion.
The anatomy of a page that performs
Each element has a role: catch Google, reassure the buyer, trigger the purchase. Here's the target structure.
| Element | Role | Best practice |
|---|---|---|
| H1 | SEO + clarity | Keyword + product name |
| First 100 words | Google relevance | Main keyword placed early |
| Length | SEO/reading balance | 150 - 300 words |
| Benefit bullets | Conversion | 4 to 6 concrete benefits |
| Product schema | Rich snippets | Marked-up price, stock, reviews |
The ultimate trap is copy-pasting manufacturer text. Dozens of stores use the same paragraph: Google indexes only one, rarely yours. Unique 150-word copy beats duplicated 500-word copy.
The measured impact of unique content
The figures below are a 2026 order of magnitude seen on West African stores that rewrite their pages. They show the dual SEO and conversion gain.
| Lever | Measured effect | Estimated gain |
|---|---|---|
| Unique vs manufacturer text | Organic traffic | +25% |
| Keyword in H1 + 100 words | Google position | +3 to 6 ranks |
| Benefit bullets | PDP conversion | +14% |
| Product schema | SERP click-through | +8% |
| Length 150-300 words | Optimal zone | Reference |
Product schema shows price, availability and stars right in Google results. This one tag raises click-through by about 8% before the visitor even lands on the page.

Mini case study
Fatou, who runs an online gourmet grocery in Dakar, used descriptions copied from her suppliers. Across 60 pages, she rewrites each text to 200 words, places the keyword in the H1 and first 100 words, adds 5 benefit bullets and Product schema. In two months, her organic traffic climbs 25% and conversion on those pages 14%. On monthly revenue of 1,500,000 FCFA, that's roughly 210,000 FCFA in extra sales, without a franc of ads.
FAQ
What's the ideal page length? Between 150 and 300 words. Below, Google lacks context; above, the buyer drops off. It's the balance zone between ranking and readability.
Where do I place the main keyword? In the H1 and in the first 100 words of the text. Repeat it once or twice naturally, never stuffing: Google penalizes over-optimization.
Is supplier text really a problem? Yes. Duplicated across dozens of sites, it's indexed only once. Unique text gains about 25% organic traffic.
What does Product schema add? It shows price, stock and reviews in Google results, lifting click-through by about 8%. It's a free gain once the markup is in place.
How many benefit bullets? Aim for 4 to 6 concrete benefits framed by use, not tech specs. Benefit bullets add about 14% conversion on the page.
