In SEO, the title is the tag: the clickable blue text that shows up in the engine's results. A page without a valid title is like a passenger stuck at the gate: it isn't going anywhere. **Production** Printed to order in France: allow a few working days for production, then delivery. **Shipping** €4.90 in France, free from €59.
