I have three products 100 directory submission 300 directory submission 500 directory submission Keywords are same and landing page is also one Should I make three ad group or one ad group to get maximum results?
Make three ad groups, that way you can write a different ad for each product, and send them to a different landing page (if you want).
That doesn't really matter for now. If the products are clearly defined and presented, it doesn't really matter if they are on the same page. The 3 different ad groups allow you to see what is more popular, and which ad drives the most traffic to your site. It also allows someone who clicked on your ad for 100 submissions, then who may prefer a greater amount, to change their mind and still make a purchase.
