Amazon Affiliate ID

Use the Affiliate ID associated with your Affiliate account. The Affiliate ID looks something like foobar-20.

Custom Field Name

This is the name of the Custom Field you will use in Posts and Pages to store the ASIN. You should give this a memorable name. We recommend ASIN.

Default ASIN(s)

This field is optional and is only helpful if you want to display products in the side-bar of each Post without having to add individual ASIN ids to each Post. This field takes a comma-separated list of one or more ASINs. The plugin will pull a random ASIN out of this list for use when displayed.

Display On All Posts/Pages?

If checked and you have defined Default ASINs to use for display, you will see the side-bar widget displayed on every Post and Page. When a custom field is defined for an individial Post or Page, that individual ASIN will be used. When a custom field is not defined, then the plugin will fall back to using one of the Default ASINs.

Display On Other Views?

Similar to above, if checked and you have defined Default ASINs, the plugin will display in the sidebar of your homepage, search results page, category page, etc.
