Google Penguin, released in 2012, changed SEO forever by punishing websites that had manipulative, or spammy, backlinks. Penguin, unlike Panda, which focused on content quality, was more concerned with the quality of links. Sites that had natural and authoritative backlink profiles were rewarded. Penguin’s core principles are still relevant today, especially as they form part of Google’s algorithm. This guide provides 2025-proof ways to rebuild trust and improve your ranking if you’ve been flagged by Google for having unnatural links. Penguin is also a great way to learn about other updates, such as Panda and BERT.
What Was the Google Penguin Update?
Penguin targets websites that use manipulative techniques to boost their backlink profile, including:
- Spammy Directory Links
- Paid links and link exchange
- Over-optimization of anchor texts with keywords
- Linking to low-authority, irrelevant sites
Penguin was originally a separate update that became part of Google’s algorithm, meaning it now happens in real time. Penguin’s modern penalties often relate to larger issues, such as expertise and authoritativeness or thin content, which was a focus for the Google Panda update.
How Penguin Penalties Hurt Your Site in 2025
A Penguin penalty can cause:
- Sudden drops in rankings for competitive keywords.
- Manual Actions via Google Search Console (e.g., “Unnatural Links to Your Site”).
- You may lose organic traffic if you have a profile that is dominated by spammy links.
An example is a finance blog that lost 70% of its traffic when Penguin flagged over 500 links to unrelated sites offering “payday loans.”.
Step 1: Identify Toxic Links with a Backlink Audit
Find the links first. You can use these tools to find links.
1. Google Search Console
Warnings can be found in the Manual Actions Report. Export backlinks under “Links > External Links.”
2. AHREFS or SEMrush
- You can flag links using Ahrefs Backlink audit tool.
- Linking to toxic spam scores
- Links that are irrelevant (e.g., gambling websites linking to health blogs).
- Anchor text that is overoptimized (e.g., “best SEO agency,” repeated more than 50 times).
3. Moz Link Explorer
Identify domains that have a low Domain Authority (DA 20).
Tip: Use SEMrush’s Gap tool to compare your backlink profile with competitors. Links from authoritative, diverse sources are a priority for healthy sites.
Step 2: Remove or Disavow Toxic Links
1. Contact webmasters
Request the removal of any spam links politely. Use email templates like:
“Hi [Site Owner],
Your site [URL] contains a link to [My Site]. Please remove the link. We’re changing our SEO strategy, and it doesn’t match your content. Thanks!”
Use a spreadsheet to track responses.
2. Remove all toxic links.
Upload a disavow file to Google for links that cannot be removed:
- Format: domain:spammysite.com or URL:http://spammysite.com/bad-page
- You can use the Google Disavow tool via Search Console.
Alert Only report spam that has been confirmed. Links can be damaged by mistakes!
3. Monitor Progress
Ahrefs/SEMrush should crawl your website monthly in order to prevent toxic links from reappearing.

Step 3: Build Authority with White-Hat Link Building in 2025
It’s not just about getting rid of bad links, but also about replacing them. Prioritize:
1. Guest posting on Authority Sites
With DA50+ is a great way to pitch niche blogs. Example:
- “2025 Ransomware Trends” is the topic of a guest blog for CSO Online by a cybersecurity company.
2. Create link-worthy content
Create resources that competitors cannot ignore.
- Original research
- Use visual assets, such as infographics and tools (e.g., a ROI calculator).
- Ultimate Guides (5,000+ Words) covers topics in depth.
Find out how the helpful content update rewards user-centric, in-depth content.
3. Leverage Digital PR
- Join forces with journalists by using platforms such as HARO.
- Case studies can be turned into press releases, e.g., “How [Brand] reduced client churn by 20%.”.
4. The importance of Branded and Natural Anchor Text
Penguin penalizes exact-match keyword stuffing. Instead, aim for:
- Branded Anchors “Learn More at [Brand name]”
- Natural phrases: “According to this study…”
Step 4: Align with E-E-A-T & Modern SEO
Google’s algorithm 2025 prioritizes trust and expertise in particular for the YMYL niche (Your Money, Your Life). You can improve your profile if you
- Add Author Bios that include credentials.
- Citing trustworthy sources
- Update old content with current SEO statistics (ex. “2025 Search Engine Statistics”).
