Should I set NOINDEX header for my JS, CSS and image files?
- by Yoga
Are there any harms if my site send NOINDEX headers for all my static assets?
For image files, I refer to those valueless, e.g. background images, button images, etc.
Update: more background information
I have this concern is since recent Google said they also execute JS and they might fetch content via Ajax. So, for example, if I send noindex for my jQuery script, so Google would not be able to use them to load Ajax, I suppose it is not good for my site's SEO, right?
