I’m very curious about Google keyword advertising.

Hello, when I search for an illegal keyword 'A' on Google, I sometimes find articles on reputable websites that contain the keyword 'A'. How is this kind of operation carried out? Is it possible to learn the method?
I have attached a photo. As shown here, the search term appears on nationally certified sites or websites with very high scores.

That’s parasite SEO.

People post on high-authority sites (forums, press sites, UGC platforms) using blackhat methods to rank illegal keywords. Could be:

Guest posts or open submission abuse
Hacked pages/subdomains
Cloaking or redirects
Paid access to publish on legit domains

It works because Google trusts the domain, not always the content. Risky but still active.

That's an interesting observation about seeing illegal keywords on reputable sites in Google search results. Typically these sites aren't intentionally promoting illegal activity. What's likely happening is the keyword 'A' appears within the site's content often in a context that's educational informative or critical of the very thing you're searching. Think of a news article discussing the dangers of drug use. They might mention specific drug names to illustrate the problem. Google indexes all the content on these sites so the keyword appears in the search result even if the overall message is against the activity. As for learning the "method" there's no secret way to make illegal keywords appear on reputable sites.

That’s actually a really interesting observation. I’ve seen similar indexed pages on high-trust domains before, and always wondered how they slipped through. Could be old, unmoderated forums or bulletin boards being exploited. If this is automated somehow, it’d be fascinating to understand the exact method behind injecting content onto such domains.

They’re almost always using black-hat SEO tricks—either quietly slipping “guest” or paid posts into high-authority sites (sometimes via exploited contributor accounts or insecure CMS plugins) or outright hacking/comment-spam to inject the keywords into comments or hidden text.


Yes, you can learn the mechanics (there are plenty of tutorials on “SEO spam” and “CMS vulnerability” exploitation), but it’s illegal and risks serious penalties.

Seen this happen too , in many cases it cloaking or expired pages that were repurposed. Sometimes it just GG associating similar terms in cached pages, even if the actual content is gone.

Often, reputable sites will create (how to, warning) content instead of direct promotion. In addition, they take advantage of the power of high domain authority and quality backlinks to keep their rankings stable. But they still have to follow the rules. If you do it right, content with quite sensitive keywords will not be affected much

What you’re seeing is mostly the result of parasite SEO.
People exploit high-authority sites ,like press sections, public forums, or even old subdomains ,to inject illegal or sensitive keywords, usually through guest post abuse, expired CMS exploits, or direct access via partnerships.
The reason they rank so well is because Google still gives priority to the domain’s trust level, not the content quality.
That said, getting these pages to stay indexed is a constant battle ,platforms patch holes fast, and Google often de-ranks them over time.
Definitely risky, and most methods used fall under exploitative black-hat SEO.
