In one Drupal 6 based site there are product pages like : example.com/product1, example.com/product2 etc but in Google search engine result pages(SERP) it is instead taking us on clicking to url's to like : example.com/product1?page=2 or page=1 or other pages and so on.
This site has Nodewords installed and has meta-description defined for each page. But in case of url's like example.com/product1?page=2 meta-description isn't appearing.
The front-page seems to be set to "/node" so I can see in the bottom of the front-page as 1,2,3,4 ... links for pagination.
I simply want Google to index the page like example.com/product1 and not example.com/product1?page=2.
Why this could be happening and how can I resolve it?
