Ever clicked a link from what looked like a serious website and landed on some weird casino, blue pill, crypto, forex, essay writing, or payday loan spam page?
That is not always because the original website owner linked to spam on purpose.
Often, something else happened.
A legitimate domain expired. A spammer bought it. The old backlinks were still pointing to the domain. The spammer then used that inherited authority to rank or support whatever spam project they were running.
This happens more often than most people realise.
Old government campaign sites expire. Embassy domains get abandoned. University project sites disappear. Charity microsites are forgotten. Public information portals go offline. Old conference websites are left to rot.
Then someone buys the domain and turns it into a spam site.
That is bad for the web.
But it is also a link building opportunity.
Because if reputable websites are still linking to a hijacked spam domain, you can help them fix the problem.
Create a better replacement resource. Contact the sites linking to the spam domain. Tell them they are currently linking to spam. Offer your clean, useful alternative.
That is the tactic.
It is broken link building, but with a stronger reason to act.
A dead link is annoying.
A live link to spam is embarrassing.
The strategy is simple:
This works especially well when the linking websites are careful, reputable organisations.
Think:
These websites usually do not want to send visitors to spam.
They often just do not know the link has changed.
Your job is to tell them and make the fix easy.
Spammers buy old domains because links still matter.
If a domain used to belong to a legitimate organisation, it may have backlinks from strong websites.
For example, an old public health campaign might have links from hospitals, government pages, universities, and NGOs.
An old embassy site might have links from travel portals, government pages, expat resources, schools, and international organisations.
An old charity site might have links from local councils, newspapers, partner organisations, and fundraising pages.
When the domain expires, the backlink profile does not disappear overnight.
The links still point there.
That makes the domain attractive to spammers.
They buy it, rebuild it, redirect it, or fill it with spam content.
The linking sites often do not notice.
And that is where you come in.
This tactic works because you are not asking for a favour.
You are solving a problem.
Most outreach emails are self-serving:
We created a great article. Please link to us.
This outreach is different:
Your website currently links to a spam domain. Here is a safer replacement.
That is a much stronger pitch.
You are helping the webmaster, editor, government employee, university administrator, or content manager improve their page.
You are protecting their visitors from spam.
You are saving them time by giving them a relevant alternative.
That is why this can produce links from websites that would normally be very hard to get.
I once found an old embassy domain that had been abandoned.
The Embassy of the Netherlands in Bulgaria had stopped using its old domain after the setup changed and people could use the consulate instead.
The old domain was then picked up by a spammer.
The site had become useless, but lots of good websites were still linking to it.
At the time, I was working for a travel client. So instead of just saying “please link to my client,” we created a genuinely useful alternative page for travellers.
The page included:
Then I emailed the websites still linking to the old embassy domain.
The message was simple:
You are currently linking to a spam website. We created a clean, useful alternative for travellers here.
Almost every site changed the link.
Many of those links came from government or government-related websites.
Those are links you do not usually get easily in a competitive travel niche.
And the reason it worked was obvious: we helped them fix a bad link with a better resource.
Normal broken link building usually means finding a 404 page and asking someone to replace the dead link with yours.
That can work.
But a broken link is often not urgent. Many site owners ignore them. A dead link is annoying, but not always embarrassing.
A spam link is different.
If a government page, university resource, or charity website links to a casino or pill site, that is a bad look.
It creates a stronger reason to update the page.
So the pitch is more powerful.
Normal broken link building says:
Your page links to something that no longer exists.
Hijacked-domain reclamation says:
Your page links to something that is now actively bad for your users.
That is a better reason to respond.
The best targets are old domains that used to belong to legitimate, useful, trusted organisations.
Examples include:
The current content is usually unrelated spam.
Common spam categories include:
The current topic does not matter much.
What matters is the original purpose and the quality of the old backlinks.
The ideal opportunity has five ingredients.
You need a clear story.
It used to be an embassy site. Or a public health campaign. Or a university project. Or a tourism resource.
You should be able to explain what it was.
The current site should clearly be irrelevant, low quality, or spam.
You do not need to be dramatic. You just need to be accurate.
This is the whole point.
You want links from good websites that have not noticed the domain changed.
If your client is in travel, an old embassy or tourism resource makes sense.
If your client is in healthcare, an old public health campaign might fit.
If your client is in education, an old educational project might work.
If your client is in finance, an old financial literacy or consumer protection site might work.
The replacement page has to deserve the link.
A thin page will not work.
You need to create something useful enough that a serious website can link to it without hesitation.
There are several ways to find them.
Search for queries where expired-domain spam is common.
Examples:
Look at the ranking domains.
You are looking for domains that feel “off”.
Ask yourself:
Example signs:
That mismatch is your clue.
Use your favourite backlink tool to inspect suspicious domains.
Look for domains with links from:
Then check the current site manually.
Does the backlink profile look too good for the current content?
That is often the giveaway.
A spam casino site with backlinks from municipalities and universities probably was not always a casino site.
You can combine spam terms with high-authority link footprints.
For example, search for spam topics and then inspect ranking domains that have backlinks from public websites.
You can also use backlink tools to filter by referring domain type.
Useful filters:
Branded anchor text is especially useful.
If a casino site has old backlinks with anchor text like “Bulgarian embassy information” or “road safety campaign,” that tells you what the site used to be.
You can also build this into a repeatable process.
Track domains in your niche that:
This is more advanced, but useful if you run link building campaigns often.
For example, in travel, you might monitor old tourism, embassy, expat, visa, and local information sites.
In healthcare, you might monitor old public health campaigns, awareness campaigns, medical charities, and educational resources.
In education, you might monitor old university projects, student resources, and defunct educational tools.
Before contacting anyone, understand the original site.
Use archived versions of the website to check:
You need this context for two reasons.
First, it helps you create the replacement resource.
Second, it makes your outreach more credible.
Instead of saying:
This link is bad. Link to us.
You can say:
It looks like this used to be a travel information site for visitors to Bulgaria, but the domain now shows unrelated spam. We created an updated traveller information page here.
That is much stronger.
Once you find a hijacked domain, export the backlinks.
Then qualify them.
You do not need to contact everyone.
Prioritise the strongest and most relevant sites first.
Look at:
Create a spreadsheet with columns like:
This is not glamorous work.
But this is where the money is.
The replacement page should match the original purpose of the hijacked site.
Do not create a generic commercial landing page.
That will fail.
Create something that genuinely deserves to replace the old resource.
Create a traveller information page.
Include:
Create a health information resource.
Include:
Create a destination guide.
Include:
Create an updated learning guide.
Include:
Create a research summary page.
Include:
The page should be more than “we also wrote something about this.”
It should feel like a worthy replacement.
This matters a lot.
You may be asking government, university, NGO, or public sector websites to link to you.
They need to feel safe doing that.
Add trust signals:
If the replacement page is on a commercial site, that is okay.
But it should not feel like a trap.
For example, if your travel client hosts a traveller emergency guide, the page can mention the company, but it should not scream “BOOK YOUR HOLIDAY NOW” every three paragraphs.
The resource comes first.
Commercial value comes second.
The replacement resource can earn links.
But you also want it to support the rest of the site.
Add natural internal links to relevant pages.
For a travel client, that might include:
For a health client:
For an education client:
Do this carefully.
The resource should stay useful and credible.
Do not turn it into an internal link dump.
Keep your first email short and helpful.
Subject: Spam link on your page
Hi [Name],
I noticed that this page on your website links to [old domain]:
[Their page URL]
Unfortunately, that domain now appears to have changed ownership and is showing unrelated spam content.
From the context, it looks like the original link was meant to point visitors to information about [original topic].
We created an updated resource on that topic here:
[Your URL]
It includes [briefly mention useful elements].
Thought I’d let you know in case you want to update the link for your visitors.
Best,
[Name]
Use this for government, university, public sector, charity, or institutional websites.
Subject: Outdated external link on [page name]
Hi [Name],
I came across this page on your website:
[Their page URL]
It currently links to [old domain]. That domain appears to have changed ownership and now displays unrelated spam content.
From the surrounding text, it looks like the original link was intended to help visitors find information about [original topic].
We have created an updated alternative here:
[Your URL]
The page includes [emergency contacts / official resources / practical guidance / downloadable PDF / references / etc.].
I thought this might be useful if you want to replace the outdated link with a safer and more relevant resource for your visitors.
Best,
[Name]
[Company]
One follow-up is enough.
Subject: Re: Outdated external link on [page name]
Hi [Name],
Just a quick follow-up in case this got missed.
Your page still appears to link to [old domain], which now shows unrelated spam content:
[Their page URL]
We created a cleaner replacement resource here:
[Your URL]
No worries if you are not the right person, but I thought it was worth flagging.
Best,
[Name]
This pitch works because it is specific.
You are not saying:
We have a great resource.
You are saying:
Your page has a problem. Here is where it is. Here is why it matters. Here is an easy fix.
That is a completely different conversation.
The recipient does not have to think very hard.
They can check the page, see the bad link, check your replacement, and update it.
The easier you make that process, the better your conversion rate.
Always include the URL of the page where the bad link appears.
Do not make them search for it.
Show exactly which link is the problem.
Say that the domain appears to have changed ownership or now shows unrelated spam.
Avoid making legal accusations or dramatic claims.
This is important.
If you can say what the original link probably used to be, your email becomes much more useful.
The replacement should match the context of the old link.
The recipient is busy.
Make the issue easy to understand.
A real person from a real company performs better than a generic outreach alias.
People miss emails.
One polite follow-up is fine.
Repeated follow-ups are not.
Do not pretend to own the old domain.
Do not pretend to be the original organisation.
Do not exaggerate the danger.
Do not call the site owner negligent.
Do not shame them.
Do not send a weak replacement page.
Do not redirect your replacement page to a commercial landing page later.
Do not ask for exact-match anchor text.
Do not contact irrelevant sites.
Do not automate this so aggressively that it becomes spam.
Do not use the tactic as an excuse to harass public sector staff.
This works because you are being helpful.
Keep it that way.
The best part of this tactic is the quality of potential links.
Depending on the original domain, you may find links from:
These are often links your competitors cannot easily copy.
Not because the tactic is impossible, but because it takes actual investigation and a good replacement asset.
That is the advantage.
You can do this manually for one client.
But you can also build a repeatable system.
Track domains that:
For example:
A hijacked tourism domain might fit a travel client.
A hijacked health campaign might fit a healthcare client.
A hijacked education resource might fit an education client.
A hijacked financial literacy site might fit a finance client.
For example:
Do not publish generic copy-paste content.
But having a reusable structure helps you move faster.
If you are a proper link building nerd, you can build a system for this.
The system could:
This turns a manual tactic into a repeatable prospecting machine.
You can even score opportunities based on:
This is where the tactic becomes really interesting.
Most link builders are still sending generic “great resource” emails.
You are finding broken trust on the web and fixing it.
Not every hijacked domain is worth your time.
Prioritise based on:
A domain with 500 junk backlinks is not useful.
A domain with 12 links from government, university, and NGO pages can be gold.
Quality beats volume.
Track the campaign carefully.
Use columns like:
Measure:
This is the kind of campaign where a small number of wins can matter a lot.
Here is how a full campaign might look.
You find a spammed old travel information domain.
It used to provide safety information for travellers in a specific country.
It now hosts casino content.
Backlink analysis shows links from:
You create a replacement page:
Travel Safety Guide for [Country]: Emergency Contacts, Consulate Information and Practical Advice
The page includes:
You contact the sites linking to the spam domain.
Several update the link.
Your client earns strong, relevant links from sites that would normally be very difficult to access.
That is the whole game.
This tactic is defensible because the link has a reason to exist.
The linking site had an outdated or harmful link.
You provided a better replacement.
The replacement helps users.
The linking page becomes better.
Your client earns a relevant link.
Everyone wins, except the spammer.
That is exactly the kind of link building you want.
Before launching, ask yourself:
If the answer is yes, you are probably doing it right.
Hijacked spam-domain link reclamation is one of my favourite link building tactics because it has a real reason behind it.
You are not manufacturing fake relevance.
You are not begging for links.
You are finding places where the web has decayed and offering a better alternative.
That is why it works.
A government website does not want to link to casino spam.
A university does not want to send students to a pill site.
A charity does not want its old partner link pointing to forex garbage.
Most of the time, they just do not know it happened.
So tell them.
Create something better.
Make the replacement useful enough that updating the link is obvious.
And enjoy the kind of links your competitors will wonder how you got.
Now go on, wayward link builder.
Find the hijacked domains.
Find the suspiciously strong backlink profiles.
Build the cleaner resource.
Email the people who should know.
And make the web a slightly less terrible place.
