Googler Says A Page Needs To Pass Quality Checks For Indexing
https://www.seroundtable.comGary Illyes from Google said on Reddit that for a page to be indexed by Google “the content still has to pass quality checks.” If that content does not pass the quality checks, Google may not index it even if you manually try to submit the page to Google for indexing.
I feel like this has been more the case ever since the Indexing tool went down and came back up. Previously any crap would get indexed (not ranked but indexed) but these days it’s not easy (or at least not as fast) as it used to be.
