Comment to How many “em.php” pages does UNA generate?
-
Hi all. In general, if you do not enable “Enable SEO links”, then the URL: “em.php” will respond with a 404 error. If you enable “Enable SEO links”, then some of them will return code 200, but not all. Of course, these URLs can be prohibited from indexing, but will this not affect the indexing of other pages? On the other hand, if you do not prohibit the indexing of em.php, then search engines will react negatively, since the appearance of a large number of 404 URLs has a bad effect.
