# Decrease latency with EU Ad Server Support

If most of your visitors are in Europe, you can serve your tags from EZmob's EU data center in Amsterdam, which is closer to them. Choose it in the placement's code view. You don't need to edit the tag by hand.

## Steps

1. Open **Sites & Placements** → **Your Placements**.
2. Click the code icon (**View Script**) on the placement.
3. Under **Data Center**, click **EU (Amsterdam)**. The default is **US East (New York)**.
4. Click **Copy Script** (or **Copy URL** for Redirect placements).
5. Replace the old tag on your site with the new one.

The dashboard doesn't save your choice. Select **EU (Amsterdam)** again each time you copy the tag.

## Supported formats

| Format | Data Center selector |
|---|---|
| Pop, Redirect, Search, In-page, Interstitials | Yes |
| Banner, Header Bidding, Video | No |

The EU tag changes only the host: `xml-eu.qualiclicks.com` instead of `xml.qualiclicks.com`. For example, an In-page tag has `host: 'xml-eu.qualiclicks.com',` in its settings.
