Does the html tag noscript load the content in the background, even when javascript is enabled?
I have a random image that is called by JS each time the pageloads, but I would like all of the links (not just the current random one) to be crawled. At the same time, I don't want the pageload to slow down because images are loading in the background like they do with display:none. I also want to call these images and links in the html because of CMS reference issues with Javascript.
Image references in NOSCRIPT tags are not loaded at all when Javascript is enabled.
You can test this my making a number of large images, putting them inside the NOSCRIPT tag and watching browser activity.
