Update October 3, 2020, Google Team has confirmed that they have fixed some indexing issues in search engines.
Muhammad Abdulloh Sani : Today we as website owners and writers get a breath of fresh air, after a few days ago there was an indexing problem on the Google search engine.
Google Danny Sullivan announced via Twitter that Google Search has been affected by two types of outages. First shutdown affects cellular indexing. The second outage involves canonicalization which affects how duplicate content is handled and displayed in search results, including syndicated content.

Problems with canonicals impact roughly 0.02% of our index, starting around September 20 to last night around 4:30 pm PT. We have recovered about 10% of those URLs and continue to reprocess even more.
Mobile indexing issues affect around 0.2% of our index, starting in early September but surging considerably from around the middle of this week to the end of yesterday. We have recovered about 1/4 of those URLs & continue to reprocess others
This update may take days to fully resolve both of these issues, but we've recovered a lot of URLs and are working fast to process even more. Especially…
We're currently working on two separate indexing issues affecting multiple URLs. One of them is by cellular indexing. The other is by canonicalization, how we detect and handle duplicate content. In either case, the page may not be indexed.
Google Search Engine Indexing Issue Have Been Fixed Today.
The announcement follows a week of anecdotal reports from the SEO community about URLs being removed.
Tweet By Google
Update: it may take days to fully resolve both these issues completely, but we have restored many URLs already and are working quickly to process more. In particular
And the result is that 5 pages from my personal site have been perfectly read by search engines today, 4 October , 2020.
In the history of Search Engines, in recent days, many websites have experienced several URLs that dropped suddenly disappeared from their existing position. Resubmitting URLs via Google Search Console seems to get them back into the Google index, do it today good luck.
Google's official Twitter account Google Webmaster tweeted that the whole day's indexing issues have been resolved. This is another in a series of technical problems. While Google has had outages in the past, it hasn't had so many outages in that short time.
What Happened To Google's Index?
It seems very coincidental that things went wrong after the March 2019 update. But Google has not provided an explanation as to what caused so many problems.
I'm not saying that Google owes the web publishing community an explanation. The bottom line is that a lot of the web publishing community is concerned. I hope all your pages can return to the previous warnings. If it is not there, then it is possible that your page was detected as duplicate content or your data structure was corrupted.
Currently 02 October 2020, Google Confirms There Are Problems With Mobile Indexing and Canonicalization
Google said some time ago that their team is fixing a problem that is currently happening and there is no action you need to take at this time. Keep calm and wait for their official decision via this page or the world's search engine pages.
If you have followed our page, you will definitely see we will report a case of unconfirmed indexing issue around URLS appearing to be out of the Google search engine index.
Problems indexing pages in search engines 02 October 2020
Last September we suspected canonicalization problems with Google and it turned out to be true. Google's official team says there are not only canonicalization issues but also problems with mobile indexing.
It is believed that this happened on September 22nd and 23rd when the SEO (Search Engine Optimization) community started noticing major changes to search results.
Confirm Google. Google's official team said through its Iwitter account Search Liaison, "we are currently working to solve two separate indexing issues affecting multiple URLs. One of them is mobile indexing. The other is canonicalization, the way we detect and handle duplicate content. In one of them is canonicalization. from in these two cases, the page may not be indexed."
Mobile indexing Issue. The official Google team explains that in some cases this will not index the page, the previously indexed page has disappeared from the search engine, this is due to mobile indexing problems, where they fail to select the page to be indexed.
Canonicalization Issue. Google also adds that it may not index the pages involved in canonical issues, URL Checker could show URLs as duplicate & Google's selected canonical will be different from that "I posted a lot of these examples here in the Search Engine Roundtable and Google even asked for examples earlier this week. In short, in some cases, Google returns completely wrong URLs for a page or doesn't display that page at all in its index."
What can you do at this time? There is no. Google has made it clear that they will tackle the problem. Google wrote, "no action can be taken on this issue on the part of the site owner. So just wait and hopefully Google will solve it soon. However this has been going on for the last 8 days or so." We will always update this article when all the problems are fixed. "Google statement. We apologize for the problem here and are working quickly to resolve it. We will update this thread as each is fixed."
Here is the official Tweet from Google some time ago.
We are currently working to resolve two separate indexing issues that have impacted some URLs. One is with mobile-indexing. The other is with canonicalization, how we detect and handle duplicate content. In either case, pages might not be indexed.... @searchliaison
If a previously indexed page has gone, it might be the mobile-indexing issue, where we’re failing to select any page at all to index. If the canonical issue is involved, URL Inspector may show the URL as a duplicate & the Google-selected canonical will be different from it…. @searchliaison
There’s no action to take with these issues on the part of site owners. We apologize for the issues here and are working rapidly to resolve them. We’ll update this thread as each is corrected. @searchliaison
I really care for you 😂. Many of you have been scratching your head since September 23 at this issue or change in Google's search engine results. Now that you know, this is probably just a bug from Google's robots. for your site's ranking and traffic hopefully will come back soon when Google's side solves this problem. It could be that your site was affected by something else and your ranking won't come back but at least you know there was some kind of bug in the Google search engine around that date.
