In one of my websites (tourism), the number of 'Page indexing > Duplicate, Google chose different canonical than user' (inside 'Google Search Console') rocketed from 210 in June to 2,300 this last week (over 58,000 total pages indexed).
If I inspect (through 'Inspect URL' of Google Search Console) any of the affected pages, I see:
User-declared canonical: https: //mydomain/list-a/city-566 (that lists all the airlines with flights to 'city-566')
Google-selected canonical: https: //mydomain/list-b/city-566 (that lists all the hotels in 'city-566')
I've checked the canonical URLs, and they are ok for both cases (they link to theirselves).
"city-566" is the same one for both cases, and the titles are similar, but not the same:
- "Airlines flying to City 566 | mydomain"
- "Hotels in City 566 | mydomain"
Both contents are different, and it's true that sometimes the content is too scarce (just listings, maps, or graphs).
I'm wondering if I should remove the last "| mydomain" of the titles. I removed it from other section and it's not affected by this issue. However, it's true that such not-affected section shows richer contents.
Any tip is appreciated. Thank you.
