Retargeting allows you to target and track visitors across sites. The biggest problem is placing the single pixel.  Search Engine Watch has a post released two days ago that cover the announcements made today.

1. Search Re targeting for Display Ads — lets advertisers target display advertising based on a user’s search activity. So a user that searches on a term like “sandals” could be served a display ad for footwear elsewhere on Yahoo‘s network.
2. Enhanced Re targeting for Display Ads — allows advertisers to deliver dynamically generated display ads across the Yahoo network based on user activity on an advertiser’s site. Going beyond standard site re targeting, the new technology would allow an advertiser to target users who visit an airline website to check offers for flights from SFO-JFK, and serve them a personalized offer for that specific flight when they visit a page within the Yahoo Network.
3. Enhanced Targeting for Search Ads — adds capabilities for Sponsored Search and Content Match ads, including ad scheduling and demographic targeting within search. New features are designed to extend the advertiser’s control over where and when an ad is shown at both the campaign and ad group level, including what time of day and day of the week an advertiser would like campaigns to run (ad scheduling), and what age and gender they’d like to reach (demographic). Advertisers will be able to vary their bids for different segments in order to increase their ability to reach the desired audience.

Search Re Targeting, Enhanced Re targeting and Pixel Placement announcements.

If your running a paid ad on Yahoo! Search and use the Re targeting option, your banner will be served on other parts of their network, example: Dell.

If your using SmartAds, a dynamic generated ad will be generated across various parts of Yahoo! Example: Travelocity coversion up 651%.

Pixelless Targeting – you define the segments and it gets passed to Achami (forgive my spelling).
Example: Chrysler

Yahoo! Believes they are bringing innovation to market. Yahoo! Does have a minimum buy of 25K a month.

A question came up about Search Re Targeting, and then I asked ifSearch ReTargeting is in play for anyone running a paid search ad, it’s not ( you have to me a head or torso customer that is paying the 25k).

Pixel Free Workd question suggests the service serving the content can inject the pixel at the time the ad is served and you can build segments that way.

On the other hand Yahoo! Has 400 segments.

My take away is these improvements will enhance Yahoo! Advertising offerings, but it’s just for the clients who are spending over 25K a month – and I think, eventually, they ought to roll this out for everyone who advertises on Yahoo!, period.
