It is such links you can copy and promote anywhere you deem fit. You can promote these links on and offline depending on what promotional efforts which work best for you. You can promote them offline using:
- Business cards.
- Car stickers
- Newspapers/magazine adverts
You can also promote them online using social media, articles/blog posts and any suchlike place which attracts good online traffic. By promoting the links online, just post them where online traffic is high with the hope that they will be clicked through with a view to making a purchase. Each product listed by any ECA carries its own unique number attached to the link gateway. Any purchase made through the use of any of such links you are promoting earns you the affiliate commission attached to that product. That is how it works in SFI/TripleClicks.
