When working on content tasks you will be asked to add SEO-friendly keywords and URLs. These keywords and URLs will be suggested to you in the Brief provided by the client.
You are free to use as many keywords and URLs as you like. The only thing you must do is use the keywords associated with the given URL.
For example, for this particular task, five URLs are suggested. If you decide to use the URL suggested on page 3, you have to use either "colis international" or "envoi colis international"—not any of the keywords suggested on page 1, 2, 4 or 5.
