how to know which keyword that people search and click to my Landing Page

I advertise Clickbank products.
I have my own landing page.

how can I automatic insert "kw" that people search on google to my hop link in my landing page.

such as :
my hop link in my landing page :- "xxxx.pub.clickbank.com/?tid="
when people search "ABCD" and click my ad to my landing page.

then hop link in my landing page will change to "xxxx.pub.clickbank.com/?tid=ABCD"

 

I believe google analytic has that features.

 

i dont know.
If who know if tell me please.

 

It is possible with adwords by adding the string "{keyword}" like "xxxx.pub.clickbank.com/?tid={keyword}". Google will replace "{keyword}" string with the keyword. But i dont know with the clickbank. Just try this method.

 

i always use Google Adwords its best tools to find keyword Value

 

I will tell you go with google adwords as it is one of the best way to find keyword value, little bit it will be expensive but it will be useful to you to get the exact idea of keywords and clicks.
