# What do I need for History to work on my website?

History is a powerful Icomm tool that allows you to show each of your users a personalized browsing history with the products they have visited on your website.

### Activation and display of History

For the History to start showing on your website, it is necessary for the user to navigate to at least one product within your page. Once the user has visited at least one product, the History tool will be activated and can be viewed in bubble format. The user simply has to click on the bubble to access the list of products they have previously visited.

### Product Tags and Open Graph Tags (OG Tags)

In order for Icomm to detect the products visited and the History to work smoothly, it is essential that each product listing on your website contains the appropriate tags. Icomm recommends the use of Open Graph Tags (OG Tags) to label your products. OG Tags are metadata that are added to the HTML code of each page to provide structured information about the content.

The minimum necessary OG Tags for the correct operation of the History are the following:

```html
<meta property="og:type" content="product" />
<meta property="og:title" content="Product Title" />
<meta property="og:image" content="URL product image" />
<meta property="og:price:amount" content="Product Price">
```
* **og:type** defines the content type, in this case "product" to indicate that it is a product.

* **og:title** sets the title of the product, which will be displayed in the History.

* **og:image** provides the URL of the product image, which will be displayed next to the title in the History.

* **og:price:amount** specifies the price of the product. This value is optional, but adding it provides additional information to your users.

||| Remember that it is important to keep these tags up to date for each product on your website, so that they accurately reflect the latest information.
