I was going through the Google Search Console pages issues and one of the issue reason is "Alternate page with proper canonical tag" and this has some URLs which look like below
example.com/abc/?hstc_sdb.sdhjb16573.328y......and so on example.com/abc/?utm_term........and son on example.com/abc/?job... and so on example.com/abc/?amp... and so on example.com/abc/?hs... and so on
and many more like this, however, i am not sure from where these are coming so i though of adding queries in robots.txt for disallowing some attributes and to avoid these types of pages to be crawled by search engines (My 1st question if this is the right and good approach)
2nd questions is what can be the exact queries to be added in robots.txt for above mentioned URLs, are the below one will solve the purpose?
Disallow: /?amp Disallow: /?hs Disallow: /?__hstc Disallow: /?job Disallow: /?utm
if not what are the right queries?
