At SEW, some say it’s only for directories, but it’s so NOT. All kinds of pages are affected. Even 4 or more years old domains.
And now I notice that some of my websites have yet again 500 pages indexed (out of the 16.000 or more real ones), and 130.000 pages that I physically removed from my server one YEAR ago, are showing up as indexed.
Don’t get my started on other issues like the link: operator.
