The “Product Tags” tab would only appear after a product has been created. Even then, there doesn’t seem a way to add tags to a product – it only displays them when you are editing the product and I see only “Reset Filter” and “Search” buttons.
So the tags are only for customers? Not administrators?
Is there any way to add tags to products when creating them? Just like you can specify tags when you are creating blog posts in WordPress. It’s an intuitive feature that helps classify the item (product or blog post) even better than categories and attributes (you can’t use too many attributes or it won’t be user friendly).
If this can’t be done from control panel. Is there any way I can do this programmatically by Magento API?
There are THREE ways to do it:
A) to add tags directly when entering/editing a product, you will need an extension, such as this one. This method is most useful to let people with less magento experience create tags (such as data entry people).
B) To add tags without leaving the administrator (not going to the frontend). This is useful for applying the same tag to multiple products:
C) To add tags via the frontend & the backend, which is useful when you want to add a lot of tags to each single product:
Now you can pick a method most appropriate for each type of use!
