# How to Aggregate the Same Type of Buttons as a Single Event

On special feature pages and cushion landing pages, multiple buttons of the same type are often installed to improve conversion rates. Here, we explain how to aggregate these buttons in bulk with specific examples.

Example: Suppose you want to measure the number of clicks on an "Add to Cart" button like the following using event measurement.

`<a href="class="add_basket" data-ItemID="STB64889″>Add to Cart</a>` `<a href="class="add_basket" data-ItemID="DTB99057″>Add to Cart</a>` `<a href="class="add_basket" data-ItemID="WTP99756″>Add to Cart</a>`

Since the above three descriptions differ in the value of "data-ItemID=", if you set one of the above:

`<a href="class="add_basket" data-ItemID="STB64889″>Add to Cart</a>`

as the source for event acquisition, you can only measure the button for one product.

Therefore, if you exclude the "data-ItemID="XXXXXXXX"" part in the event settings management screen, you can measure the number of clicks on the "Add to Cart" button regardless of the value of "data-ItemID=".
