• The creative cannot appear to be a cutout with a dotted line.
• All audio must be user initiated.

• If a coupon is featured in the creative, the ad cannot link to a page that requires the user to download software before printing the coupon as this is a poor user experience. If downloading software is required to print the coupon, the user must first redirect to the advertiser landing page. The user can then redirect to the site requiring the software download from the advertiser landing page.
• Creative development may be available - additional production time required. Contact Yahoo! Homepage Advertising Team for details.
• Homepage advertising must meet the Yahoo! Ad Content Standards and Guidelines. Check with your Yahoo! Sales Representative for details.

If you choose to run the same creative multiple times we suggest some of the following changes as an option to keep it fresh and compelling to users:

• New look and feel
• different background color
• different layout of the final frame
• animation - change of sequence
• different animation of copy/message
• color of the copy/messaging
• different images throughout the animation and on the final frame
• unique offer
• different copy or a continuation of the story with a slight variation
• change the call-to-action

CPU Usage
Idle CPU usage typically falls within 8-12%. When testing a Flash file for the homepage, CPU usage after the initial loading of the file must be between 20% and 30%. An initial spike of up to 60% is acceptable in the first five seconds. (Idle CPU usage devised upon computer with a 2.0GHz Intel Pentium Processor and 512 MB of RAM running standard programs.

LANDING PAGES
The offer in the creative must be present above the fold on the initial landing page and must be consistent with the creative messaging.

Landing page(s) must be live for content review 48 hours prior to campaign launch. If the event runs over a weekend or on a Monday, the landing page(s) must be live by 12pm PST the Friday prior to launch.

Landing page(s) must be able to support an estimated 15-20 users per second. Note: This estimation is based on peak traffic & performance; it is NOT an estimation of sustained traffic or activity throughout the campaign. Applies to third-party tracking pages as well.

No pop-ups/pop-unders on the destination URL or triggered from the back button allowed.

It is recommended that all landing pages be HTML5 compatible since this ad unit may display on tablet devices.

BROWSER
Rich Media and Marquee Events
The Yahoo! Homepage serves the full advertising experience to users with high bandwidth and Flash & JavaScript enabled. A low bandwidth experience will be served to all users, and a static backup experience will be served for JavaScript disabled users, those who don't have flash installed or are on a dial-up connection.

Bandwidth Detection:
Bandwidth detection will determine which version of an ad will be displayed to a user. A low bandwidth version must be supplied for any ad over low bandwidth max file size in order to accommodate these users or they will default to the back static gif/jpg.

U.S. BROADBAND COMPETITOR ADVERTISING RESTRICTIONS

MISCELLANEOUS

Advertisers must ensure that any advertising that claims to offer items for "free" fully complies with all state and federal guidelines with respect to the use of the term "free" in advertising. Any sign-ups, promotions or special offers must also adhere to these restrictions and guidelines.

Advertisers must ensure that any advertising offering "free" items discloses all material terms and conditions for obtaining the free item (e.g. advertising may not suggest that an item is "free" when receiving the item is in fact conditioned upon signing up for or purchasing the advertiser's good or service, unless that fact is properly disclosed).

The News box and Today Module on the Yahoo! Homepage is editorially controlled. In determining what news is posted on the Homepage, the editorial team considers a wide range of criteria including: newsworthiness, relevance and interest to our audience. News is a primary driver of Homepage usage and we believe creating a trusted experience sets the stage for the largest, most captive audience for Yahoo! and our advertisers. Yahoo! cannot guarantee that positive or negative news content will be featured on the Homepage at any time during the advertiser's flight. These types of situations do not warrant a make good, given Yahoo!'s need to be unbiased with news content.
