Google indexing advert images as site content

[bumpski]

Just checking the site: directive in Google Images on one of my sites; images from ads are now being credited to the site as if the site hosted them. Specifically lots of Amazon ad images and it appears images directly from Adsense advertiser websites are appearing credited to my site by Google Images.

As an aside; I've known for years that if you place a text link to another site's image Google Images will credit that image to your site in Google images, but now it's ad images imported by javascript advertiser code.

I just added Amazon recommendation ads in the beginning of November (12% commission), now I see all sorts of content related images and what are likely personally targeted images as well that are credited to my site. (The Amazon recommendation ads doubled the page load time of the site, so they're gone after November.

Anyone else?
Just go to Google images and use site: for your sites.

Yes, that's correct. If an image displayed on your site (no matter how) the citation will be also.

I've run Adsense and Amazon ads since 2005 or so and this is the first time Google Images has ever shown images from Adsense and Amazon ads with a site:mysite.com search. One could guess that Google Images has just started parsing javascript, obviously Google search has parsed javascript for quite a few years. From my point of view this is completely new behavior from Google Images.

And I do continue to be astonished that images on other sites show in a "site:" search for my site just because I have a text link to them. For example when I do site:mysite.com Google Images credits the National Institute of Health Logo to mysite.com. This quirk has been this way for years. In this text link case the image most definitely is not displayed on mysite.com.

But these new ad images are just clutter! Clutter, by the way, that you will typically only see if you search far down in the "site:" search results. I hope Google fixes this new quirk.
