Free Link Building Tool

Our link building tool turns a competitor's backlink profile into a working prospect list. The premise is simple: a site that already links to your competitor covers your topic and is open to linking out, which makes it a far warmer prospect than a cold name pulled from a generic list. Enter one competitor and the tool surfaces the domains linking to them, ranked by authority, with the link type and a spam score on every row so you can sort the strong prospects from the noise.

The workflow is one step. Enter a competitor domain. We pull their top referring domains from DataForSEO, attach each domain's authority rank, dofollow status, and per-link spam score, and present the list with live filters. Slide the minimum-rank control up to focus on authoritative sites, toggle dofollow-only, or hide high-spam domains, then export the full list to CSV for outreach. Results are cached for 24 hours.

For Link Builders

Our tool gives you a vetted starting list instead of a blank page. Work it to:

• Filter to high-authority, dofollow, low-spam prospects in seconds
• Skip domains with high spam scores before you waste an outreach email
• Export to CSV and drop straight into your outreach sequence

For Agencies

Our tool helps you scope a link campaign with real targets. Use the list to:

• Show a client exactly which sites link to their competitors
• Quote a realistic prospect count after filtering for quality
• Hand the team a prioritized, CSV-ready target list

Why Use Our Link Building Tool

• Real quality signals: Every prospect carries DataForSEO's domain rank and a per-link spam score, so you filter on data, not guesswork.
• Filter, then export: Narrow the list on screen with the rank, dofollow, and spam controls; the CSV includes the full set so nothing is lost.
• Honest about scope: The list covers the competitor's top 100 referring domains (the free-tier cap), and a link to a competitor is a possible prospect, not a guaranteed one. We never fabricate "why they'd link" reasoning, you vet relevance yourself.
