Hreflang block does not list the page itself
What it means
These pages list hreflang alternates but do not include themselves. A page must name its own language in its own block, or search engines cannot tell which language the page they are looking at is written in, and may discard the whole cluster.
How to fix it
Add an entry for the page itself, with its own language code and its own URL. The simplest way to get this right is to generate the block from one list of every URL in the language group and output the same list on every page in it, including the page doing the output.
Finding it in CrawlStat
