What BacklinkVoid is
BacklinkVoid is a free, self-hosted backlink prospecting and audit tool for SEO specialists, link builders, and agencies. It scores prospects from 0 to 100 using relevance, authority, domain health, link-friendliness, TLD/language/geo fit, and spam safety. It audits existing links for spam and toxicity and automatically excludes toxic neighborhoods and dead, parked, or de-indexed pages from prospect lists. The browser-based web app can export PDF, Excel (.xls), and CSV results, as well as generate a Google disavow.txt file with domain lines and matched signals as comments. Backlink Notif uses a Telegram bot and cron to check for newly spammy or toxic backlinks and send weekly alerts; each monitoring start runs for one year. The project has a PHP web app for cPanel or shared hosting and a Python command-line edition for automation and cron. The web app requires PHP 7.4+ with cURL and OpenSSL; the CLI requires Python 3.8+ and no packages to install. Authority estimates are approximate without a paid API, though a CSV domain-rating column can be used. Excel and Google Disavow exports and weekly Telegram monitoring are web-app features; CLI support is described as planned.
