Most agencies use Moz the same way they use a phone book: open Link Explorer, sort competitor backlinks by Domain Authority, copy the top 200 into a spreadsheet, hand it to an outreach specialist. Three weeks later you have 400 sent emails, four replies, and one placement on a DA 31 blog nobody reads.
The problem isn't Moz. It's that DA-sorted lists aren't prioritized lists. A proper Moz integration for link building pulls the metrics into the system where work actually happens, scores prospects against how your team wins links, and turns changes in your link profile into tasks that appear on someone's board without a human noticing them first.
What a Moz integration actually gives you
The Moz Links API exposes a handful of endpoints that matter for prioritization work. You don't need all of them:
- URL Metrics — Domain Authority, Page Authority, Spam Score, linking root domains, external link count. One row per URL. This is your scoring backbone.
- Linking Root Domains — who links to a target, with per-domain DA and first/last crawl dates. This is how you build gap lists.
- Anchor Text — distribution across a domain. Useful for spotting over-optimization risk before you brief another 20 exact-match anchors.
- Top Pages — highest-authority pages on a domain, which tells your outreach team what to pitch against instead of blindly emailing the homepage contact.
- Link Status / Lost Links — the single highest-ROI feed for most agencies, and the one nobody automates.
Billing is metered in rows. One URL Metrics call on one URL is one row. A 12-client agency checking 200 prospects per client per month, plus weekly lost-link sweeps on each client domain, sits somewhere around 3,000–5,000 rows monthly. That's a real number to plan against — batch your requests, cache metrics for 30 days, and only refresh for domains that reach outreach stage.
Why DA-sorted prospect lists waste hours
Sorting by DA optimizes for one variable and ignores the four that actually determine whether a link happens: relevance, contactability, editorial posture, and effort. We tracked outreach across a 9-month period at one agency and the pattern was consistent:
- DA 70+ prospects: 1.4% reply rate, ~11 hours of specialist time per placement
- DA 40–69 prospects: 6.8% reply rate, ~4.5 hours per placement
- DA 20–39 prospects: 12% reply rate, ~2 hours per placement
At a blended $85/hour internal cost, a DA 75 link costs roughly $935 in labour and a DA 45 link costs $382. If the client retainer allocates $2,000/month to link building, the DA-first list buys you two links. The scored list buys you five, three of which are topically closer to the money pages.
The fix isn't to chase low DA. It's to stop treating DA as the sort key and start treating it as one input in a score.
Build a link priority score from Moz fields
The five inputs
Every prospect gets a 0–100 score. Weight these to match how your team actually wins links — a digital PR team and a niche-edit team should not use the same weights.
- Authority fit (30%) — not raw DA. Score highest inside your client's productive band. For a DA 38 SaaS client, the band might be 30–65: a DA 55 prospect scores 30/30, a DA 82 scores 12/30, a DA 18 scores 6/30.
- Topical relevance (30%) — manual or classifier-assigned, 0–3 scale. A DA 30 industry publication beats a DA 65 general lifestyle blog almost every time.
- Spam Score inverse (15%) — Spam Score 0–4 gets full marks, 5–7 halves it, 8+ zeroes the whole prospect regardless of other inputs.
- Link economy (15%) — external links per page and whether the domain has added new linking root domains in the last 90 days. A site with 400 external links on a single page is a link farm wearing a blazer.
- Contactability (10%) — named author, working contact form, active social. Costs nothing to check and predicts reply rate better than DA.
Turning scores into tiers
Scores are only useful if they map to a decision. Three tiers is enough:
- Tier A (75+) — personalised outreach, custom asset if needed, up to 3 follow-ups. Cap at 40 per client per month so quality holds.
- Tier B (50–74) — templated outreach with one personalised line, 2 follow-ups. Volume play.
- Tier C (under 50) — archive. Don't delete; re-score quarterly, because DA and relevance both drift.
Four automation triggers worth building
Once Moz data lives in your project system, you can stop running manual audits and let the data create the work.
1. Lost link reclamation
Pull Lost Links weekly per client. Any lost link where the source page PA is 25 or higher auto-creates a task: "Reclaim: [source domain] → [target URL], PA 31, lost 4 Feb", assigned to outreach, due in 5 days. Reclamation converts at 20–35% in our experience versus 5–8% for cold prospecting, and it takes about 15 minutes per attempt. It is the cheapest link you will ever build, and almost every agency discovers these losses two months late during a quarterly audit.
2. Competitor gap refresh
Monthly, pull Linking Root Domains for three competitors, subtract your client's existing referring domains, score the remainder. Anything scoring Tier A drops straight into the prospect queue with the competitor's linking page attached as context. Ten minutes of setup replaces a half-day analyst task.
3. Authority drift alerts
If a client's DA drops 3+ points
