Disavow File Validator
A disavow file validator checks your disavow.txt file line by line against Google's format rules before you upload it. Paste your file or upload it, and this free tool shows every problem, the line it is on and how to fix it. It needs no account and never changes your file.

What is a disavow file validator and when should you use it?
A disavow file is a plain text list of pages or domains that you ask Google to ignore when it looks at links to your site. One wrong line, such as a domain written without the domain: prefix, can make an entry mean something different from what you intended. This validator labels every line as a comment, a domain entry, a URL entry or a problem, and explains each problem. It only reports. To get a corrected file, use the Disavow File Cleaner. To automatically clean or normalize syntax errors, process your list with the Disavow File Cleaner. If you need to generate a new disavow submission from scratch, use the Disavow File Generator or identify unnatural links using the Toxic Backlink Checker. For advanced link management, combine multiple disavow files with the Disavow File Merger, compare submission revisions using Compare Disavow Files, or export directives to a spreadsheet via Disavow File to CSV. Clean raw Google link exports with the Search Console Links CSV Cleaner, remove redundant domains using the Backlink List Deduplicator, extract hostnames with the URL to Domain Extractor, and analyze TLD distributions with the Backlink TLD Distribution tool.
