Magento Indexing

Why Magento needs indexing?

Magento Indexing is used to improve speed or performance of our web store. Indexing is how Magento changes data such as products, categories etc. As data changes, the changes data must be changed or re-indexed.
For Example: Suppose you change the price of an product from $4.99 to $3.99. Magento must reindex the price change to display it on your Front-End.

Magento uses re-index data from the Admin Panel. A good way to re-index data from command shell because in some condition when we want to re-index data we will get an error message and re-index process will be broken.
In Magento, there is a folder with name “shell” in this folder, you will find with name indexer.php.
