I've posted in the Google AdSense forums, but to no avail... so since there are lots of nice and friendly, and knowledgeable, webmasters here in our DreamHost forums, I figured I'd take a shot here.... (if the narrative is too long, please jump to my BIG question at the bottom... are the files I've placed on my site safe?)
Recently, I was perusing my logs and noticed a lot of 404 errors, that I believe are coming from the use of Google AdSense. The three that I see most often are:
From the research I've done, it appears as though I may be missing out on ad revenue if these files don't exist, as some of the ads being served up are flash based and/or "iframe busters"... which need these files to exist locally. I don't use iFrames on any of my sites, but these files are still being called, and receiving 404 errors, so I'd like to fix them, even if it won't have an impact on revenues.
Now, I've seen some Google/DoubleClick articles that make these files seem to be legit:
However, I can't seem to find the files I'm actually supposed to use... except for the DARTIframe.html one... it was linked from the AdSense forums, and was a google.com hosted file, so I think it's legit. But, I can't find "official" files for the other two.... I've found them at various websites, and brought them over to my site. It seems to have fixed the 404 errors, and only time will tell if my ad revenues go up.
Thanks for your help!
