Expansion Rules for Rich Media

Must be either Mouse Over/Mouse Off or Click Open/Click Close

Mouse Over/Mouse Off:

When user passes mouse over ad, the ad will expand; when user removes mouse from ad the ad retracts.

Click Open/Click Close:

Panel opens with user click. Panel closes on either click or at end of animation period.

Lead Times

Zillow requires 2 business days prior to campaign launch dates for receipt of standard creative assets. Zillow requires 5 business days prior to campaign launch dates for receipt of rich media creative assets on Zillow.

In-Banner Audio and Video

Audio:

User-initiated audio is accepted (ad must be muted until user interacts specifically with the ad).

No host-initiated audio is permitted on Zillow.

Ad creative must contain clearly visible "mute" and "stop" functionality.

Video (in-banner streaming)

Video can be host or user-initiated and must have standard controls (play/pause, audio/mute, and stop).

Maximum length: 15 seconds

User-initiated audio is only accepted.

• Zillow reserves the right to reject any insertion, graphic, text description, or URL.
• Total animation cannot exceed 15 seconds. Animation can begin again on mouse over, but must stop immediately on mouse off.
• All ads must open a new window on click-through.
• Generally, faux-functionality—or misleading users into clicking on an ad—is not permitted. As a general rule, true functionality ads should avoid use of Zillow color schemes. If the functionality ads do use Zillow color schemes, however, the ads must include text such as "advertisement" (in the upper bar or top left-hand side of the banner).
• Ads may not employ rapid / "strobing" animation of any graphic, copy, or background element(s).
• Banners should be encased in a border and distinct from the content. If borderless, a banner must contain the advertiser's name to signify that it is an ad creative banner, not content.
• Ads must be designed with a solid/opaque background to avoid color conflicts on the display page.
• Ads may not interact with or manipulate Zillow content (e.g. highlighting text, moving content, changing color of text, etc.).
• No pop-up ads are allowed on Zillow.
• Sponsor of the advertising message must be clearly identified.
• Advertiser's landing page must match the offer being made in the advertisement.
