Link Spam Penalty and Disavow: When and How to Act

A penalty for unnatural links comes in two types. A manual action shows up in Search Console and requires a cleanup and a reconsideration request. An algorithmic effect notifies no one: Google simply stops counting the bad links. Disavow is an advanced tool that, according to Google itself, most sites do not need to use. If the term "backlink" is still new to you, start with what backlinks are.

Quick summary

• A manual action is the decision of a human reviewer, appears in the Manual actions report in Search Console and has an exit process: fix the problem and request a review.
• An algorithmic effect triggers no notice. Google's systems neutralize links they consider artificial, and sites that relied on them lose rankings.
• Disavow is for links you cannot remove that caused, or will probably cause, a manual action. Most sites do not need it.
• Dumping your entire backlink list into a disavow file is not a good-faith effort and will not get a reconsideration request approved.
• The best "recovery" is never needing one: a natural link profile and rel="sponsored" on paid links.

How to read this post: if you are new to SEO, read the first two sections and the step-by-step, which show how to find out whether you have a real problem. If you already work in SEO, jump to the disavow decision table, the file format and the edge cases.

What is a link spam penalty?

It is a consequence for links created "primarily for the purpose of manipulating rankings," which is how Google's spam policies define link spam. The list includes buying or selling links for ranking purposes, excessive link exchanges, links generated by automated programs, and articles or press releases with optimized anchor text distributed on other sites.

Google detects this through automated systems and, when needed, human review, which can result in a manual action. The difference between the two paths determines everything you do next.

In plain English: think of traffic enforcement. A manual action is the ticket that arrives in the mail: you know you were cited, you know why, and you can contest it. An algorithmic effect is a radar that quietly stops counting your points: nobody tells you, but the scoreboard changes.

	Manual action	Algorithmic effect
Who decides	A human Google reviewer	Automated systems (such as SpamBrain)
Notice	Yes: Manual actions report and Search Console messages	No notice
What happens	Part of the site or the whole site may be demoted or removed from results	Neutralized links stop passing ranking credit
How to recover	Fix the problem and submit a reconsideration request	No request exists: the systems reassess over time
Disavow	May be necessary	Generally unnecessary

How do I know if I have a manual action?

Open the Manual actions report in Search Console (it sits in the Security & Manual Actions menu). A green check means no issues. If there is an action, the report describes the type and the affected pages, and Google also notifies you in the Search Console Messages section.

The two types tied to links are "Unnatural links to your site" (the suspicious pattern comes from outside) and "Unnatural links from your site" (the suspicious links are the ones you publish). If you have never set up Search Console, the beginner's guide to Search Console shows how.

For SEO professionals: the action can be partial. Google says that for links to your site, it may affect parts of the site or the entire site. That changes the diagnosis: a drop confined to one directory can come from a link campaign pointed only at it.

What if traffic dropped and there is no manual action?

Then it is not a manual action, and the cause may be something else. Compare the date of the drop with the updates listed on Google's search ranking status dashboard, which records spam and core updates throughout 2026. If it coincides with a spam update and you have a history of bulk-bought links, the link-neutralization hypothesis gets stronger.

In that case, Google's documentation on spam updates is direct: with specific link spam updates, making changes may not produce an improvement, because the benefit those links provided was removed. There is no "appeal" to file. The path is to replace that credit with legitimate links and content.

When is disavow worth using?

Almost never. Google says that in most cases it can assess which links to trust without additional guidance, and that the tool should only be used if you have a considerable number of spammy or low-quality links and they have caused, or will likely cause, a manual action. The page also warns that incorrect use can harm your site's performance.

Situation	Use disavow?
Manual action "Unnatural links to your site" and links the site owner did not remove	Yes, after attempting removal
History of bulk-bought links and real risk of a manual action	Judge case by case; first try to remove them or qualify them with nofollow
Random spam links (scrapers, comments, junk directories)	No: this is part of the normal noise of the web
Traffic drop with no manual action	Not as a first response; investigate content, technical issues and updates
Suspected competitor attack	Generally no; monitor the report and act only if a manual action appears

In plain English: disavow is a formal notice saying "do not associate me with these sites." Used when it is not needed, you risk distancing yourself from links that were actually helping.

Step by step: from diagnosis to reconsideration request

Follow the order below. It mirrors what the manual actions documentation recommends for unnatural links.

1. Confirm the action in the Manual actions report and note the type, the date and whether it is partial.
2. Export your links from the Links report in Search Console, by top linking sites or in chronological order. Google warns that the report is a sample, with tables of up to 1,000 rows and exports of up to 100,000. Complement it with a backlink tool.
3. Classify each domain in a spreadsheet: legitimate, doubtful or artificial. Start with those with the highest volume or the most recent.
4. Ask for removal (or for rel="nofollow" to be added) from the people who run the sites. Keep dates, emails sent and replies.
5. Build the disavow file only with what was not removed (format below) and upload it in the tool, for the same property as the action.
6. Submit the review request through the Manual actions report, describing what caused the problem, what was done and what changed.
7. Wait. Google says reviews can take from days to weeks, and link-related ones can take longer. Responses arrive by email and in the Messages section.

What does a disavow file look like?

It is a .txt file in UTF-8 or 7-bit ASCII, with one URL or domain per line. Lines starting with # are comments, and an entire domain takes the domain: prefix. The limit is 100,000 lines and 2 MB, with URLs of up to 2,048 characters. You cannot disavow a subdirectory, such as example.com/en/.

# Blog network: 3 emails with no reply (Oct 12, 19 and 26, 2026)
domain:example-blog-network.com
domain:another-spam-example.net

# Single link, the rest of the site is legitimate
https://mixed-site.example/page-with-paid-link.html

For SEO professionals: each upload replaces the property's previous list, so download the current file before editing. Effects take a few weeks to reach the index. To undo everything, there is a button to cancel the disavows in the tool itself, and that also takes weeks. Prefer domain: when the whole site is junk and a single URL when the domain is legitimate and only one page is the problem.

How do I write the reconsideration request?

Write it like a short, verifiable report: cause, action, change of practice. Google is explicit on one point: adding all backlinks to disavow blindly is not considered a good-faith effort and is not enough to get the request approved.

1. What happened: own the source (for example, a link package bought in 2024) without making excuses.
2. What was done: number of domains analyzed, contacts sent, removals obtained and how many went into disavow. Many people attach a link to a spreadsheet with the evidence; this is common practice, not a Google requirement.
3. What changed: how you now acquire links and qualify paid ones.

Hypothetical example: a dental practice receives a manual action for "Unnatural links to your site" in October 2026. The links report shows 412 domains; 360 came from a single link-package vendor. The team contacts 60 sites, 11 remove the link and 8 add nofollow. The remaining 341 go into the disavow file, each with the date of the attempts. The request describes this process and states that new links will only be added with rel="sponsored" when payment is involved.

How do I avoid getting there?

Avoid building links you would not want to explain to a reviewer. That covers bought links that pass credit, mass exchanges, repeated anchors and site networks. Qualify paid links with rel="sponsored", as the post on dofollow, nofollow, sponsored and UGC explains, and track anchor and domain diversity in your natural backlink profile.

If you plan to buy links, first read is buying backlinks safe?. Google treats links bought to manipulate rankings as a violation of its spam policies, and any Contentor backlink package (links on Brazilian, Portuguese-language sites) should be evaluated with that risk in mind, with a gradual pace and relevant links. Also see the SEO glossary if any term got away from you.

Frequently asked questions

Do I need to use disavow on my site?

Probably not. Google states that most sites do not need the tool, because its systems usually know which links to trust. It is meant for cases with many spam links and a manual action (or a clear risk of one). Without those signals, disavow brings more risk than benefit.

Can spam links pointing at me bring my site down?

Random low-quality links are part of the noise of the web, and the documentation says Google usually assesses them without help. What triggers a manual action is a pattern of manipulative links. If there is no action in Search Console, monitor the links report and do not act on reflex.

How long does Google take to approve a reconsideration request?

Google speaks of days or weeks, and says link reviews can take longer. If the request is denied, review what was missing: expand the cleanup, document your removal attempts better and only then send a new request.

Is removing the disavow after approval a good idea?

There is no reason to remove links you really do not want associated with the site. Canceling disavows takes weeks and can reopen the problem. Keep the file current, with date and reason comments, so anyone on the team understands the decisions in future audits.

Can I use disavow for links I bought myself?

If you cannot get the vendor to remove or qualify the link, yes, that is an intended use, especially with a manual action. Before that, formally ask for removal or nofollow and keep proof. From then on, qualify any paid link with rel="sponsored".

Next step

After cleaning up the profile, the challenge is measuring what the good links deliver. Move on to measuring backlink ROI and turn Search Console into a control routine.
