French is the written language of Senegalese commerce, from storefronts to classifieds, but Wolof dominates speech, radio and social video, and local ads often mix the two. Prices are in West African CFA francs (XOF), shared with the other UEMOA countries, so a Dakar price page can look like its Ivorian or Malian counterpart while offering different stock and delivery. Payment is mobile-first: Wave and Orange Money are the wallets most people pay with, and many merchants take them alongside cash on delivery.
The platforms worth watching are mostly Dakar-centred. Jumia runs a Senegalese store, one of its core markets, while Expat-Dakar and CoinAfrique carry classifieds for cars, phones and property, with CoinAfrique also covering other francophone markets. Gozem runs its ride and delivery app in Dakar. News and advertising traffic concentrates on Seneweb, Senego, Dakaractu and the state daily Le Soleil. Listings from regional cities such as Thiès, Saint-Louis and Ziguinchor are thinner and can price differently from the capital.
Ranking checks need to run from Senegal, because Google, the dominant engine, answers French queries with a mix of Senegalese sites and French or Ivorian pages. Personal data falls under Law No. 2008-12 of 25 January 2008 on the protection of personal data, supervised by the Commission de protection des données personnelles (CDP), which has been working on a revised text.
Religious holidays set the Senegalese sales calendar more than imported events do. Before Tabaski, the local name for Eid al-Adha, sheep prices become a daily topic in news and classifieds, and demand for fabric, tailoring and new clothes peaks alongside it; Korité, marking the end of Ramadan, brings a second clothing and food peak. The Grand Magal of Touba, the Mouride pilgrimage held each year on the 18th of Safar, draws millions of pilgrims to Touba, and transport demand and road traffic surge around it. Black Friday promotions from online stores and electronics sellers add a late-year peak. Because Islamic dates move about 11 days earlier each year, these peaks shift across the calendar.
