Hi, Goodroi!
Thank you for your reply. About the question you mentioned, i will answer below to help you know our situation. Because we are stuck on this problem, we do need the help from you, thank you again.
1.how did you test to see if the pages were indexed in Google?
We search the brand + download on google, or use site:example.com/rescue/ download , but with the two methods, we can ‘t find the target pages.
2.Did you look it up in Search Console?
We searched this page in URL Inspection, and it does show the two pages are not indexed by Google.
Because i can't add screenshots here, i extracted some useful information here:
For German site: it shows:
1) Coverage: Duplicate, submitted URL not selected as canonical.
2) Discovery:
sitemaps: [url]https://www.example.com/sitemap.htm[/url]
3) Crawl:
Last Crawl: Sep 17, 2018, 11:37:05 AM (Because we tried to submit this page to google with this URL Inspection tool)
Crawl allowed: YES
Page fetch: Successful
4)Indexing:
Indexing allowed: Yes
User-declared canonical: [url] https://www.example.com/de/rescue/download.htm[/url]
Google-selected canonical:[url] https://www.example.com/de/resuce/download-android.htm[/url] (For this, i will go to this page, and change the rel=canonical and link to download.htm, is this ok? )
For Japanese Site: URL is not on Google
1) Coverage: Crawled - currently not indexed
2) Discovery:
sitemaps: [url]https://www.example.jp/sitemap.htm[/url]
3) Crawl:
Last Crawl: Sep 11, 2018, 10:21:23 AM
Crawl allowed: YES
Page fetch: Successful
4)Indexing:
Indexing allowed: Yes
User-declared canonical: [url]https://www.example.jp/rescue/download.htm[/url]
Google-selected canonical: Inspect URL
3. Did you do a site: search?
Just like I answered in Question 1, we did search them with site, and found they are not indexed by Google.
4.Do all of these pages have a significant amount of unique text? Have you checked to see if there might be duplicate content on another website or a possible outside hijacking attempt?
For this question, our German pages’ content are unique, we can’t find any similar content on other pages. While Japanese content can be found in others sites, because it only mentions this version supports the operating systems, and iPhone models. But I don’t think this will become a reason makes both of them disappeared from Google.
5.Do all of these pages have backlinks pointing to them?
Yes, both of the two pages have many backlinks from high-authority sites. And the numbers are growing.
6.Have you checked the status codes in your log file the last time Googlebot visited those pages?
We used the Fetch as Google in Google Search Console to check the two pages, both of them show the status as “Complete”, and URL Inspection also show both of them can be crawled, but not indexed.
7.Do you have a server monitoring service so we can rule out that your server might have been down or timed out when Googlebot visited?
For this, I don’t think it would be this reason, because we just found the two pages are not indexed, and others pages can be indexed, and get organic sessions from Google.
Thank you very much. Today, we also try to add some inner links to the download pages from some pages with high-authority, and check if the two pages will be indexed.
