Google Is Not A Source
You don’t credit a photographer by listing the search engine as the source of the image. Likewise, you don’t credit Google when you search for a news article, or a blog post. Follow the link and find the actual source. Don’t be lazy.
This also goes for Flickr, Picasa, SmugMug, Reddit, etc. Someone posted the article/image to those services, credit that user, not the service.
That is all.
