Check out the Disavow File Generator.
The Disavow File Validator was made by senior ex-Google engineer and senior ex-Google Search Quality team member Fili.
Fili has penalized countless websites for bad linking practices, was part of the official Google Search reconsideration team (Google penalities) and while at Google wrote the book (internally) on what to penalize and how to penalize, including identifying and penalizing bad linking practices.
No, the purpose of the Disavow File Validator is to test and validate your disavow file and the patterns in it before uploading it to Google Search Console.
If you need help auditing your backlink profile, why not hire ex-Google Search Quality team members who used to penalize websites for blackhat link building techniques and were also part of the Google reconsideration team?
Unlike some other tools online, the Disavow File Validator may take a few minutes to process and test your disavow file. When finished you will receive an one-time email with a link to the report. Your email address is not used for further mailings, just for this one email to let you know the analysis is ready and where you can find it. When you receive the email with the link to the analysis, your email address has already been deleted from my database.
It depends on the queue and your disavow file. Most analysis are done in a matter of minutes. If you haven't received the report email within a day, check your spam folder and otherwise contact Fili as you may have discovered a bug needing to be fixed.
Yes! Not only is it free, you can use it as many times as you need.
Be aware, the Disavow File Validator is still a work in progress, and bugs can happen. Contact Fili with bugs or any questions you may have.
After 31 days, the analysis of your disavow file and the newly generated disavow file become inaccessible and will return a 404 (not found). Of course you can rerun the analysis for free at any time.
Every line of code for the Disavow File Validator and Disavow File Generator is written by SEO expert and ex-Google engineer Fili. The Disavow File Validator and Disavow File Generator are under constant development and improvements will be added over time.
Provided email addresses are not used other than to notify the submitter that an analysis of a submitted disavow file is ready, after which the email address is unrecoverably and securely deleted.
Uploaded disavow files and/or patterns are anonymized and may be stored long term for testing and research purposes, but are never to be accessible and/or shared externally or publicly. New disavow files, and the analysis, are only publicly shared with the provided email address and accessible through the auto-generated and anonymized link for the first 31 days and after that become inaccessible and unavailable.
Bugs will happen. Despite best efforts to maintain the code base and data quality, no guarantees can or will be given. Data may be incomplete and/or errors may occur. This is a personal website and for-fun project. Use at your own risk.
