# Redirect Basics

The Redirect Response Mode allows the control of tag destinations after tags have been deployed. It's a very powerful, flexible and easy to use option. 

When using the Redirect Response Mode, tags will link to the ixkio server first and then instantly redirect to your destination web page. You can change the destination and the redirect rules of your tags as many times as you like quickly and easily. 

## Getting Started with Redirect

{% embed url="<https://www.loom.com/share/cd1957eea10c446f9ef167da539d9c10?hideEmbedTopBar=true&hide_owner=true&hide_share=true&hide_title=true>" fullWidth="true" %}

## Key Features

### Rules

[Rules ](/features/rules.md)allow tag scans to be redirected via ixkio to your website/page based on criteria that you decide such as number of scans.&#x20;

For example, you can define a Rule that directs your tag scans to Page A on the first scan and then Page B for all subsequent scans.&#x20;

Rules can be set at the Tag Group Level or at the individual Tag Level.&#x20;

### Subtags & Datamerge

Ixkio allows the active creation of redirect links using system data. You can construct entire URL using data dependent on the user, system or location of the tag within the ixkio structure.&#x20;

Subtags allows data to be included within the URL. Datamerge allows data to be included onto the URL.&#x20;

For example :&#x20;

#### Subtags

Let's say you have a tag in a Batch called 'blue'. You create a rule with the URL : \
\
`https://authnfc.com/t-shirts/{batch}`

When the tags is scanned, the Batch name 'blue' is actively included into the URL to create :&#x20;

`https://authnfc.com/t-shirts/blue`

There's a large list of available subtags which allow you to create complex and powerful active links - either for changing landing pages or for website/Google analytics.

[Read more about Subtags](/features/subtags.md). &#x20;

#### Datamerge

Datamerge allows you to append data to the end of a URL. Let's say you have a URL such as :&#x20;

`https://authnfc.com/t-shirts/blue`

When the tags is scanned, datamerge can add data onto the end as a query string, such as :&#x20;

`https://authnfc.com/t-shirts/blue?size=medium`
