Algeria has one of the largest populations in North Africa, and small sellers reaching customers through Instagram and Facebook, especially around Algiers and Oran, are a real and growing part of how people shop.
What matters for an Algerian seller's page
Arabic-first, right-to-left design is the default your customers expect. Cash-on-delivery ordering remains the most trusted way to buy from a small, growing account, since it removes the risk of paying before seeing the product. A WhatsApp block matters just as much, since that's where most buyers confirm delivery details after ordering.
Algeria is also a French-speaking market alongside Arabic (many sellers write captions in French, known locally as "lien dans la bio"), so if you advertise in French on Instagram or Facebook, make sure your page's content and product names are clear regardless of which language a given customer reads first.
Build the fundamentals right, Arabic-first design, cash-on-delivery, and WhatsApp, and the page works whether your audience found you through an Arabic or French caption.
