Checking for Valid Amazon Link

My friend who start to learn Amazon affiliate ask me whether I can check which version of these link that work :

http://www.amazon.com/gp/product/1430231149/tag=xxxx-20

or

http://www.amazon.com/gp/product/1430231149?tag=xxxx-20

I don’t know the answer since there are many variation of of Amazon link but I do want to know too. After checking affiliate panel I know that I miss one important link that Amazon provide from long time ago.

Link Checker

Just enter those 2 links and hit “Check Link” button.

For 1st link I got this message :

Fail: The link above was not tagged or was not a valid Amazon link.

For 2nd link I got this message :

Success: The link tags to a valid tag or sub-tag for your Associate ID.

p.s : I change xxxx to valid associate tag.

Very useful link as many will lost their referral fees when use it incorrectly 🙂
