DoubleClick Standard Tags
Standard tags are a type of ad placement tag used by DoubleClick. They consist of an anchor tag (<A HREF>) and an image tag (<IMG SRC>). The following is an example of a DoubleClick standard tag:
<A HREF="https://ad.doubleclick.net/ddm/jump/Nxxxx.site-keyname/Byyyyyyy.Pzzzz; sz=widthxheight;kw=[keyword];ord=[timestamp]?"> <IMG SRC="https://ad.doubleclick.net/ddm/ad/Nxxxx.site-keyname/Byyyyyyy.Pzzzz;sz=widthxheight;ord=[timestamp];dc_lat=N;dc_rdid=Czzzz;tag_for_child_directed_treatment=I?" BORDER=0 WIDTH=X HEIGHT=Y ALT="Click Here"> </A>
It's possible that advertisers may also have sent you the URLs from the anchor and image tags. You can easily identify them as they will contain /jump/ or /ad/ in the URI path. Commonly these will be input into the Image URL and Redirect URL fields in AdvertServe.
DoubleClick has been advising advertisers that they would discontinue support for standard tags for placements larger than 1x1 for some time now. Most advertisers should have already sent you new tags by now. Since DoubleClick has disabled standard tags as of October 2, however, we have been contacted by several publishers who see broken images where their ads should be appearing. If you see broken images on your web site or e-mail newsletters chances are that you may still be running DoubleClick standard tags.
Fixing The Issue
We are seeing a lot of confusion with advertisers trying to send GIF/JPG/PNG images to publishers along with a separate 1x1 tracking pixel for e-mail placements. This is incorrect. E-mail banners only support loading a single image whereas a GIF/JPG/PNG image and a tracking pixel is two images, which simply cannot work. Advertisers need to instead provide a 1x1 standard tag as instructed in the previous paragraph.
Keep in mind that DoubleClick standard tags may continue to be used as noted above for 1x1 tracking pixels, which commonly may be embedded in other types of creatives such as HTML5 banners intended for the web.
