Link Sniper

Backlink Sniper is a free, web-based SEO tool designed to help indie hackers and bloggers build backlinks without paying for expensive suites like Ahrefs or SEMrush.

Unlike browser extensions (like Check My Links) that require you to manually visit every page, Backlink Sniper automates the process. simply enter a niche keyword (e.g., "travel resources") or a specific URL, and the tool will:

Auto-Detect Targets: It intelligently searches Google to find high-value "Resource" and "Links" pages in your niche.

Deep Scan: It crawls those pages to identify broken external links (404 errors) that you can pitch your content to replace.

Smart Validation: It uses a custom "Anti-False-Positive" engine to distinguish between actual dead sites and active sites that simply block bots (firewalls), saving you from embarrassing outreach mistakes.

Key Features:

Cloud-Based: Runs entirely in the browser; no installation or heavy Chrome extensions required.

Smart Filtering: Automatically ignores "junk" links (ads, social media shares) and false positives.

Deep Link Detection: Validates links even if the homepage is active but the specific article is dead.

100% Free: No credit card, sign-up, or monthly limits.

Best For: SEO professionals, Content Marketers, and Bloggers using the "Broken Link Building" strategy to grow Domain Authority.
