title spams in SERPs

One potential customer shows me his situation: a lot of japanese links appear with his domain, when searching on Google. He asks me to clean it. I thought I read somewhere that I need to clean in GSC, but hopefully someone can share the correct way to do it?

Thank you.

Did you try GSC for cleaning the links?

Random Japanese Titles are appearing in SERPs for his domain?

You can remove these from SERP if you go to GSC and then click on "Removals" and request a removal.

I would still look for what actually caused this because the above is just a temp. fix.

Your website got hacked most likely,
You should reinstall the websites files as some might be affected and the virus will return eventually,

Do this by deleting all the wordpress files except wp-config.php, .htaccess, rbotos.txt, ads.txt & wp-content folder,
Then replace the folders from a fresh wordpress installation, you'll need to double check the above files/folders manually as well,

Reinstall the theme & plugins & replace all of their folders with fresh updated versions,
You might want to remove all the uncessary plugins or probably some that has been added by the hackers to easily reinject the website,

Next, check the website users as you might have ton of spammy new users added to the website,
delete all of them & change the other users passwords as well,

Then, you'll need to install wordfence to scan all the remaining files in the wp-content folder as some might be infected as well,
normally this is better to be done manually, usually the injected files do have a bigger size so they're easier to spot, take your time and fix all of them,

Even then, sadly the website will still struggle in the SERPs especially with the recent G updates and you might have a long period where the website is doomed,
So, if you don't have much data added to the website, you might want to start over with a new domain with a fresh installation & redirect the old domain to it

The dreaded Japanese keyword hack probably. Check some of these guides for ideas on what you can do:

You need to disavow the links and also check website security for vulnerabilities and your website code for spam.

Verify your site in GSC, then use the Security Issues section to check for hacks and unwanted software. If you spot weird URLs, you can request Google to remove them. Might want to beef up security on your site too, to prevent future attacks.

Thanks a lot for replies.

Since this is not on your client's site, you can't use the GSC to clean it.
