How to Tell if an Image is Indexed

[CPollock]

Is there a way to tell if an image is indexed in Google Images?

This won't help with the image question but you can see Google Property data in Google Analytics by going to:

Traffic Sources>Search Engine Optimization>Queries and then selecting the secondary dimension of 'Google Property'.

images.google.com used to be show up as a referrer, but Google changed that and lumped it in with organic search.  So I don't think there's a good way to see it in GA anymore.  Hopefully someone can correct me if I'm wrong!

I found one post where someone edited their GA script so it would start reporting images.google.com traffic separately: http://jrom.net/google-images-in-google-analytics.  You might consider that if it's important to you.

Yeah this is a good thought, but unfortunately these images are hosted on flickr so that won't help me too much.  I'm in the process of moving them to my site and I'm trying to figure out what impact that might have on my search traffic.

I have a general followup to this question:

If I find out that an image is indexed in google images, is there a good way to track (using google analytics) how much traffic a particular traffic is being driven by the image?

Thanks for all the help.

I think this sounds like the way to go.

[Unity]

I go to Google Image search (http://images.google.com/) and then do a site search and then look through each image, e.g. do this in the search field
site:www.yourwebsite.com

If the website has thousands of images indexed and it's not possible to look through all entries then do the site search and then add a word from the file name e.g. like this
site:www.yourwebsite.com pillow

Alternatively, post the image URL and I or someone else here can check for you!

Google images can search by image!  Go to images.google.com, and click the little photo icon on the right of the search bar.  You can search by image URL, or upload the image directly to Google to search.

You should be able to search by the filename and/or by the Alt text used to describe the image. I would start with the filename. If the filename is generic (e.g. 001.jpg), then it will be close to impossible to find, and this is a very good example for why your filenames should be more descriptive.

Hope this helps!
