Broken Link Prospector
Give it the public resource pages you want links from, and it finds their dead outbound links, shows what the dead page used to be, and exports a tidy outreach list.
Economics
- Pricing example
- $15 for 200 pages checked (first 10 free)
- Daily math
- 1-2 packs a day x $15 = $15-30/day; about 40 packs a month averages $20/day.
- Target if you hit the daily math
- Target: $500 - $800 / month if the daily math is hit
Audience and urgency
Audience: SEO freelancers, content marketers and small agencies doing link building for clients.
Urgency: Broken-link outreach works best with a specific, helpful message, but finding dead links on resource pages means clicking every link by hand. Big SEO suites can do it but are priced for full-time SEO teams.
MVP scope
- ✓ Paste a list of resource page URLs (the user finds these themselves)
- ✓ Fetch each page once (respect robots.txt, polite rate limit), extract outbound links with anchor text
- ✓ Check each link's status (HEAD then GET fallback) and flag 404/410, DNS failures and redirect loops
- ✓ Show the last archived snapshot of each dead link using the Internet Archive's Wayback availability API
- ✓ CSV export (page, dead link, anchor text, archived snapshot); credit packs via Stripe
Omitted features
- - Do NOT scrape search engines to find resource pages
- - Do NOT find or store personal email addresses
- - Do NOT send outreach emails from the tool
