At its annual summit in Salt Lake City, software optimization provider Omniture introduced an application that gives marketers the ability to automatically personalize content or product recommendations offered to website visitors.

Average landing page conversion rates for email campaigns ranged from around 5.7-11.3% for free offers, and from 5.7-7.6% for e-commerce campaigns, according to a study from MarketingSherpa. About half of landing page visitors bail in the first eight seconds, Silverpop found in a separate study.

The app from Omniture purports to increase landing page conversions by customizing each user's experience, using algorithms to track their previously viewed pages, items they've added to (or removed from) shopping carts, and overall site activity.

Marketers can use that data to display relevant products and content, thereby maximizing their efforts. Recommendations can be modified along different parameters such as price ranges and product categories.

Omniture also announced a partnership with Eloqua to track and measure such online marketing programs.

Existing Omniture clients include eBay, Wal-Mart, Forbes, Tribune Interactive, MiamiHerald.com, and ESPN.com., who pay for up-to-the-minute, detailed data on what users do on their sites.

The company has developed a reputation for delivering near-real-time data that enables webmasters to react speedily to changes in consumer behavior. But last month Forbes outed the firm for feeding days-old — and increasingly irrelevant — visitor data to clients in December.

Omniture attributed the delays to a SiteCatalyst maintenance release.
