Short answer: Google’s link spam policy says links created mainly to manipulate rankings break its rules. That includes buying or selling links that pass ranking credit, excessive link exchanges, large-scale guest posting with keyword anchors, automated link building and links hidden in widgets or press releases. Google mostly ignores such links through its systems and can take manual action against sites that rely on them.
Every SEO beginner should understand this policy before doing any off-page work. It explains why many old tactics stopped working and why some can harm a site.
What Google Counts as Link Spam
| Practice | Example |
|---|---|
| Buying or selling links | Paying for a dofollow link in an article without marking it |
| Excessive link exchanges | “Link to me and I will link to you” schemes |
| Large-scale article or guest post campaigns | Dozens of posts with keyword-rich anchor links |
| Automated link building | Software that creates profiles or comments in bulk |
| Required links | Terms that force a dofollow link to you |
| Hidden or low-quality links | Links in widgets, footers across many sites, or comment spam |
| Press release anchor links | Optimised anchor text in distributed releases |
The full wording is in Google’s Search Essentials spam policies. Read the official page when in doubt.
How Google Handles Link Spam
- Algorithms: systems such as SpamBrain detect and neutralise many spammy links, so they simply stop counting.
- Manual actions: a reviewer can apply a penalty, shown in Search Console’s Manual Actions report.
- Lost investment: even when nothing is penalised, money spent on spam links is wasted.
How to Mark Links Correctly
| Situation | Attribute |
|---|---|
| Paid or sponsored placement | rel=”sponsored” |
| User-generated content like comments | rel=”ugc” |
| Any link you do not vouch for | rel=”nofollow” |

Safe Link Building in Practice
- Create content people want to reference.
- Build real relationships with relevant sites.
- Keep anchor text natural. See anchor text types.
- Use directories and profiles that real users visit.
- Mark any paid placement as sponsored.
If You Already Have Spammy Links
Most low-quality links are ignored automatically. If you have a manual action or a clear history of bought links, clean up what you can and consider disavowing. Read toxic backlinks and disavow before using the tool.
