Google is indexing ajax pages with hastags since 2015: https://webmasters.googleblog.com/2015/10/deprecating-our-ajax-crawling-scheme.html
However, is there a possibility to exclude specific URLs with a specific hash tag (because of duplicate content, i.e. sorting parameters)?
- example.com/#!explore/world (is OK to be indexed)
- example.com/#!explore/world:sortby=date (should not be indexed)
Since the page does not get reloaded after the hash tag changes to a new ajax page, it does not make sense to use the
<meta name="robots" content="noindex"> tag, since it would count for ALL ajax hash URLs...
