How to fix the Japanese keyword hack

Japanese titles for your domain in Google, and no sign of them on your own site. Here is what the warning means and how we can help.

By Hamza Rivera, updated

Short answer: The Japanese keyword hack can put spam pages under your domain without showing them to you. Passieon checks the site and Search Console, cleans the intrusion, and handles the search damage. Google decides what remains in its index.

How to tell you have it

Search results show pages you never made

Japanese titles and descriptions, or product names for goods your business does not sell, are a common sign. Google describes the hack as creating new pages with Japanese text in randomly generated directory names, monetized with affiliate links.

Search Console has a Security Issues message

Open the Security Issues report. Google lists hacked content there and often shows sample addresses. If the report is empty, the hack may still be present, so do not treat an empty report as clean.

Google sees something you do not

Many of these hacks show the spam to Googlebot and a normal page to visitors, which is cloaking. The URL Inspection tool in Search Console shows how Google fetched a page. Compare it with what you see in a browser.

Unknown owners in Search Console

Google says hackers are sometimes added as site owners in Search Console. Look at the list of owners and users for anyone you do not recognize.

What our cleanup covers

  1. 1

    Confirm the affected pages

    We compare search results, Search Console reports and the live site to identify spam pages and hidden redirects.

  2. 2

    Clean the WordPress installation

    We inspect files, database entries and access for injected content, then remove the cause and keep a backup of the affected site.

  3. 3

    Address the search damage

    We check spam URLs and Search Console ownership, then use the relevant Google tools after the site is clean. Google controls its index and review outcomes.

  4. 4

    Reduce the chance of a repeat

    We review access, updates and backups, then give the owner a clear record of the changes and remaining risks.

Questions about the Japanese keyword hack

What is the Japanese keyword hack?

An attacker uses a weakness in the site to create many pages with Japanese text in randomly named directories. The pages carry affiliate links, usually to stores selling fake brand goods, and are shown in Google Search under your domain. Google describes it that way in its own guidance on common hacks.

Why can I not see the spam pages on my site?

The hack often uses cloaking, so visitors see a normal site and search engines see the spam. Use the URL Inspection tool in Search Console and a site: search to see what Google has.

Will deleting the spam pages from WordPress fix it?

Usually not. The pages are often created on the fly by rewritten server rules and hidden files, so there may be nothing in your WordPress page list to delete. The files and rules that create them have to go.

When will the spam leave Google?

Google decides when to recrawl and remove addresses. We check the affected URLs and report what Google shows.

Can you fix it for me?

Yes. Passieon is an independent agency, not connected to Google or WordPress. Send your address through the form for a free written check.

Can you guarantee the pages leave Google?

No. Google decides what stays in its index. We clean the site, make sure the spam addresses return the right status and file the requests Google provides.
