1) Are Amazon associates allowed to attach an affiliate link to an image?
For instance, a picture of a hammer linked to a hammer for sale on Amazon.
2) Are there rules about how a text link must appear?
For instance, if I want to link to a hammer on Amazon, can the text link say, "Hammer nails easier than ever!", or does the text have to include particular info?
3) How do you track Amazon sales?
From what I understand Amazon doesn't want it's links altered, so I assume I can't add them to a tracking service like Improvely, etc..
If I want to include the same affiliate links on various pages on my website, how will I know which page performs the best?
