Link Building

Link building tools fall into two categories that get confused constantly:

1. Data tools — backlink indexes, link gap analysis, competitor profiles. Already covered by your keyword research tool. Don’t double-pay.
2. Outreach tools — prospecting, email sequencing, response tracking. These are where the actual category lives.

What to buy

For most small agencies, the answer is don’t, until you need to. Manual outreach with Hunter.io ($49/mo) for email finding plus a Google Sheet is fine for the first 50–100 pitches/month.

Once you cross that threshold:

• BuzzStream — relationship-based outreach CRM for small teams. See the BuzzStream review and BuzzStream vs Pitchbox.
• Pitchbox — premium link building platform for high-volume outreach. See the Pitchbox review.
• Respona — campaign-oriented link building workflow for teams that want more guided execution. See the Respona review.
• Hunter — email finding layer for lean manual outreach and prospect validation.

Where this fits in the stack

Link building is downstream of keyword research (for prospect lists from competitor backlinks) and parallel to content optimization (for the linkable assets you’re pitching).

The honest take: for most small agencies, link building should be a productized service line powered by data from your existing keyword tool, not its own tool category. See the SEO tool stack for small agencies for the full picture.
