Definition
The Disavow File is a UTF-8 encoded text file (.txt) that webmasters submit to Google's Disavow Links tool in Search Console to flag backlinks they want Google to ignore when calculating their ranking. The file follows a specific format: each line contains either an individual URL to disavow or an entire domain preceded by the domain: prefix (e.g., domain:spamsite.com). Comment lines start with #. Best practices include disavowing at the domain level rather than URL by URL for entirely toxic sites, adding comments explaining why each domain is disavowed (for future reference and reconsideration requests), never disavowing your own domains or quality domains, and keeping a version history of the file. Google processing can take several weeks after submission. A misused disavow file can harm rankings by eliminating beneficial links.
Key Points
- .txt format in UTF-8 with one URL or domain: per line and comments starting with #
- Prefer domain-level disavow (domain:) for entirely toxic sites
- Each new submission overwrites the previous file: always include all entries
- Excessive or poorly targeted disavow use can harm by eliminating beneficial links
Practical Examples
Basic disavow file format
A typical disavow file contains descriptive comments followed by directives: # Spam directory links / domain:spamdir1.com / domain:spamdir2.com / # Spam comment links / domain:blogspam.net
Domain vs URL disavow
For an entirely toxic site, use domain:toxicsite.com to disavow all links from the domain. For a partially acceptable site, disavow only specific URLs like https://semilegit.com/spam-page.
Incremental update
Each quarter, the SEO adds newly discovered toxic domains to the existing disavow file and resubmits the complete file. The old file is overwritten, so always include all previous entries.
Frequently Asked Questions
Google recommends using the disavow only if you have received a manual action for artificial links or if you are certain you have a significant number of spam links pointing to your site. Excessive preventive use can be counterproductive if you accidentally disavow beneficial links.
No, Google indicates that disavow file processing can take several weeks. Disavowed links are progressively ignored during subsequent crawls and PageRank recalculations. Do not expect immediate changes after submission.
