The verdict in three sentences
On mobile, the product page drives 60 % of the purchase decision: this is where a visitor becomes a customer or vanishes. The levers that matter are photos (5 or more), the FCFA price visible without scrolling, stock availability, a sticky CTA and reviews. An optimized page converts twice as well as a raw one, without a single extra franc of acquisition.
The 7 elements that sell
A high-performing product page is not a catalog: it is a sales page. Each element plays a measurable role in mobile conversion.
| Element | Conversion impact (2026 order of magnitude) | Priority |
|---|---|---|
| 5+ photos | +22 % vs 1-2 photos | Critical |
| Product video | +30 % engagement | High |
| FCFA price visible without scroll | +12 % add-to-cart | Critical |
| Sticky buy button | +9 % clicks | Critical |
| Stock shown ("only 3 left") | +8 % urgency | Medium |
| Customer reviews (4+ stars) | +18 % trust | High |
| Clear delivery time | +7 % checkout | Medium |
The golden rule: everything that matters must fit in the first mobile screen. Name, price, main photo and buy button should never require a scroll.
Photos, video and speed: the winning trio
Visuals carry the sale. But in West Africa where 3G still dominates, every image must be compressed without visible loss.
| Media parameter | 2026 target | Consequence if ignored |
|---|---|---|
| Number of photos | 5 to 8 | -22 % conversion under 3 photos |
| Image format | WebP / AVIF | +40 % weight in JPEG |
| Page load time | < 2 s on mobile | -7 % sales per extra second |
| Weight per photo | < 120 KB | Slow page, drop-off |
| Short video (15-30 s) | 1 per hero product | +30 % engagement |
A page that loads in more than 3 seconds loses half of its mobile visitors before even showing the price.
Mini case study
Awa, who runs a ready-to-wear shop in Dakar, sold through a product page with 2 photos and a price hidden at the bottom. Mobile conversion: 1.2 % on 3,000 visits/month, i.e. 36 sales at 18,000 FCFA = 648,000 FCFA.
After a redesign (6 WebP photos, a 20-second video, price shown at the top, a sticky "Order" button, 12 reviews), her conversion rose to 2.3 %, i.e. 69 sales = 1,242,000 FCFA/month. A gain of 594,000 FCFA per month without spending a single extra franc on ads.

FAQ
How many photos does a product page really need?
Aim for 5 to 8 photos from multiple angles, plus a material detail and a lifestyle shot. In 2026, going from 2 to 5 photos raises mobile conversion by about 22 %.
Does the price really need to be visible without scrolling?
Yes. A price hidden at the bottom cuts add-to-cart by 12 %. The FCFA price must appear in the first screen, next to the buy button.
Is a product video worth the investment?
For your hero products, yes: a short 15-to-30-second video raises engagement by about 30 %. A well-lit smartphone video is often enough.
How do I handle photos without slowing the page on 3G?
Convert everything to WebP or AVIF (< 120 KB per image), enable lazy loading and a CDN. The page must load in under 2 seconds on mobile.
Should I display remaining stock?
Showing "only 3 left" creates healthy urgency and can add up to 8 % conversion, provided it is true. Never fake scarcity.
