Always disclose your affiliate relationship. Most visitors will probably understand that graphic ad will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.

There’s strategy in brand development, marketing, etc… This is insulting to the creative industry to label logo and branding as a scheme to make extra money.
AWIN is probably best for experienced affiliates who can hit the ground running without a lot of guidance or feedback from the network.

AWIN operates globally, but it is most heavily concentrated on British and EU merchants.
