Unknown Google problem with my site

1,5 months ago, I started creating a WP theme for my sites.
I have a bunch of sites, among which I have the following sites:

• Seo / Friendly / Domains / .com
• Best / Dubai / Tours / .com
• Peru / Tourist / Guide / .com - Only this site has a problem with indexation
• Tanzania / Travel / Guide / .com

I started the theme creation with the site about domains.
Then I added the almost-ready theme to the already existing site about Dubai and also created a new site about Peru and another one about Tanzania.
The site about Dubai already had 10-20 posts, mostly with no content (just posts with images and titles).
To the site about Peru, I added 20+ posts, mostly with content.
I created only 1 post on the site about Tanzania.
Here I stopped with site development and continued with the theme.
All the modifications and editions I did to the site about domains and later uploaded the updated PHP files to other sites.
Everything was ok, and I saw 10+ indexed posts from the Peru site.
But one day, happened something weird, Google started showing the main page of my domain site as the main page of the site about Peru.



I thought it was my fault and checked all the theme's files, but no file has any mention of the site about domains.
The theme is clean and ready to be uploaded to any site.
I checked robots.txt, .htaccess, and other files, but everything was ok.
But Google continues showing the wrong front page.
Then I copied the URLs of the wrong page and deindexed it via GSC.
I removed only the URL, not the site.



A few days later, Google started to deindex my already-indexed posts.
As you can see in the first screenshot, actually I have only 2 indexed URLs.
Then I decided to try the same theme with other sites and created a site about Tanzania and also uploaded the same theme to the already existing site about Dubai.
Both sites have no similar issues, no front page from the domain site, and no deindexation.
You can check them both on Google.
I also checked the site about Peru on Bing and it is indexed.
So, the problem with the deindexation is Google...
But why Google shows there the front page of the domain site?
Why Google suddenly mixed up my 2 different sites?
I re-uploaded all WP files and I am sure the site about Peru has nothing related to the site about domains.
So, what's happening with my site?
Where is the cause of this weird problem?



I added the site to GSC on November 3.
On November 5, I saw the wrong front page showing by Google as the front page for the Peru site, the same day I removed that URL via GSC.
From the next day, my indexed posts started to disappear.
The domain itself was dropped and registered in August, so all previous history of the domain was removed.
However, more than 10 posts got indexed the next day I published them.
The de-indexation problem started later.



I think the problem could be caused by some history of the domain, but the history was removed when it was dropped.
Besides, how does the front page of another site suddenly appear in the results of the Peru site?
This could happen only if I uploaded some of the files of one site to another.
But what file?
The theme files have no link to any site, the theme is clean, and I have checked it.
Then what?
It could be due to some file transferred from the Seo / Friendly / Domains / .com, but I used the same theme on my other sites and there is no similar issue.
I could accidentally upload a .htaccess file or robots.txt from another site, but I already checked all these files and re-uploaded all the site.
I could accidentally upload the wrong .HTML file which GSC generates for ownership confirmation, but my other sites use the same file and have no similar problem.
I uploaded the same plugins from the site about domains to the site about Peru, but I always do the same and never affected any site.
Besides, I already re-uploaded all plugins.
I have no idea where to search and how to fix it.

 

It sounds like you've been on quite a rollercoaster with your websites lately. From what you’ve described, it seems like a perplexing issue, especially given that everything looks clean on your end. Google can sometimes be quirky, especially with indexing, and it might be struggling to differentiate between your sites due to some underlying factors. Have you considered reaching out to Google Support?

 

Does Google have support?
I had no idea Google had support.
How can I contact them?

 

They don't have support.

As for your issue, what you are seeing is what typically happens when the content is deemed of low value by the algorithm or is largely available on a lot of other sites. Recent algorithm updates are doing this. Its mostly a waste of Google's computing resources to keep crawling and indexing low value content.

 

Who told you my content was deemed of low quality?
And how does it explain the mix of 2 different sites in the same search results?

 

I have no idea. I did not even look at your content. It does not matter what you or I think about the quality of the content.
Its a matter of what and how the algorithm interprets it and then compares it to what is already in the index.
Typically, recently, when there has been a lot of de-indexing of pages on a site, it is because the algorithm has decided there is an issue with the content its not worth indexing and ranking it (in the absence of technical reasons as to why google can not crawl the content).

 

You should read the whole post before commenting.

I did.

 

I am not sure you did.
Otherwise, you would have noticed this screenshot.

 

You can start by checking their Search Central Help Community.

 

I already have asked there, but still no answer.
It's weird, because the previous URL with the title and text from the footer widget, was /51-2/ and the current one is /translator/01am/......
This means, it is another page from the same site...
But how and why?
The site about Perú is the only one where I added the translate button, but the PHP file has nothing related to other domains.
I will try to temporarily remove the translation button...
PS: No, the problem is not the button, because the translation button was created after 28.11.2024, and the URL from another site first appeared just after I added the site to the GSC and it was 3.11.2024



I created 3 new sites and activated this theme + all my plugins but there is no similar issue on other sites.
.

 

It sounds like something unusual is happening with the URL structure. You mentioned that the footer widget's text and title were previously linked to a different URL, which is puzzling. It could be worth double-checking the configuration of your translation button and any potential conflicts with your theme or plugins.
Even though you've already ruled out the button itself, perhaps there's something in the site settings or a plugin that could be affecting how URLs are generated. Have you checked for any caching issues or settings in the GSC that might be influencing this behavior?
If removing the translation button doesn't work, you might also want to look into any recent changes in your site's configuration or server settings around the time you noticed the issue.

 

Why you just can't open both sites and see what I am talking about?

• Type in Google: site:https://perutouristguide.com
• See the 2nd link: It has a favicon, title, and text from the footer of the site SeoFriendlyDomains.com
• Open SeoFriendlyDomains.com and check what I mean.

No, I didn't clone the site about Peru using the files of SeoFriendlyDomains.
No, I don't have any cache plugins.
No, the theme's files have no mention of SeoFriendlyDomains.

The footer description was added correctly using the WP widget section and not directly into the PHP file.
I created the theme following the WP rules.
I also asked GPT to check it all, and yes, all done correctly.

My other sites with the same theme have no a similar issue.

 

I found some interesting facts.
The current link that Google shows when I type site:https://perutouristguide.com is one of the old links, from 2018-2019.
So, Google removed my recently posted and indexed posts, but found the old, non-existing link, carefully continuing to keep it and showing in the results.
They are idiots.
But it still doesn't explain why Google added to that link the favicon and the footer description from my other site on a different domain.
