Why not just use the built in method for specifying them? Easier than re-inventing the wheel.

For each product and category there is a little icon next to the edit icon you can click on to specify custom meta tags... "admin" -> "catalog" -> "categories / products" -> click the little icon for meta tags (it reminds me of a radiation symbol).

Do have many category and Products. so ITs takes to much time for add title. Thats why... want to do this
