What is the purpose of Landing page? Can i Use my Website Home Page or other pages as Landing page? OR better to make other page?
If you advertise a jewelry store, the home page can go but if you advertise a special ring in that store your landing page must be the ring's selling page.
I would setup a specific landing page for each of your Ad Groups. Your overall keyword score will increase if the Ad matches the content on the landing page. Setting up different landing pages also allows you to focus on one product or service.
