Moz API V2 Link Intersect Endpoint Documentation – Help Hub – Moz

If backlink research had a detective badge, the Moz API V2 Link Intersect endpoint would wear it with unreasonable confidence. This endpoint is built for one of the most useful questions in SEO: who links to my competitors, but not to me? That question sounds simple, but the answer can save you hours of blind outreach, random prospecting, and the classic “let’s email everyone with a website and see what happens” strategy, also known as chaos with a spreadsheet.

The beauty of the Moz API V2 Link Intersect documentation is that it turns competitor backlink analysis into something developers and marketers can actually automate. Instead of clicking around a dashboard forever, you can send a structured request, get structured JSON back, and build a repeatable workflow for link gap analysis, prospect prioritization, reporting, and outreach. In other words, this endpoint helps move backlink strategy from vibes to evidence.

What the Moz API V2 Link Intersect Endpoint Actually Does

At its core, the Link Intersect endpoint returns sources that link to one or more specified “positive” targets while excluding sources that already link to one or more “negative” targets. In plain English, that means you can tell Moz, “Show me sites linking to these competitors, but not to my site.” That is the whole party trick, and it is a very good one.

This matters because competitive backlink analysis is not just about spying on rivals for sport. It helps you uncover missed opportunities, identify patterns in your niche, and focus your outreach on websites that already link to similar content. If a site has linked to several competitors in your market, it has already raised its hand and said, “Yes, I publish this kind of thing.” That is a much better signal than cold-emailing a random blog that has never linked to anyone in your space.

How the Endpoint Fits Into Moz API V2

Moz’s V2 links data endpoints live under the https://lsapi.seomoz.com/v2/ base URL, and Link Intersect sits at /link_intersect. The documentation and supporting examples point to an authenticated POST workflow with a JSON request body and JSON responses. That is good news for developers because JSON is easy to pass around, log, validate, and turn into dashboards, internal tools, or reports that do not look like they were assembled during a caffeine emergency.

One important detail from Moz’s own materials: Link Intersect is a weighted endpoint. That means usage is not counted one-for-one in the same way as a simple lightweight request. If the endpoint returns five intersecting links, the row consumption can be higher than five. Translation: this is not the place for sloppy trial-and-error at scale. Test smart, watch usage, and build your workflow like someone who enjoys keeping their quota intact.

Commonly Referenced Request Elements

Based on Moz’s endpoint materials and companion examples, a typical Link Intersect request revolves around a handful of practical fields:

• positive_targets: the competitors or pages you want to analyze
• negative_targets: the site or pages you want excluded, usually your own
• min_matching_targets: how many positive targets a source should match
• source_scope: whether you want page-level or broader source treatment
• sort: how you want results ordered
• limit: how many results to return in one go

That structure is useful because it lets you tune how strict or broad your prospecting should be. Want a tighter list? Raise the matching threshold. Want bigger, more strategic domains first? Sort accordingly. Want to avoid sending your outreach team into a swamp of low-value prospects? Start with conservative limits and review the quality before expanding.

Example Request Body

You do not need to memorize that. You just need to understand the logic: define who you want included, define who you want excluded, then tell Moz how picky to be.

Why SEO Teams Love Link Intersect

The Moz API V2 Link Intersect endpoint documentation is not exciting because it is technical. It is exciting because it is useful. There is a difference. This endpoint helps SEO teams do four valuable things well.

1. Find backlink gaps without guessing

Backlink analysis works best when you compare your site to the sites already outranking you. Instead of manually crawling competitor profiles and pretending that is fun, Link Intersect surfaces a shortlist of websites that already link within your niche. That makes prospect discovery faster and far more relevant.

2. Prioritize outreach opportunities

Not every linking source deserves an email. Some deserve applause, some deserve caution, and some deserve to be quietly ignored forever. Link Intersect becomes more powerful when you sort prospects by authority, relevance, and fit. A small list of strong opportunities usually beats a giant list of questionable ones.

3. Build better content pitches

If a site links to three competitor guides on the same topic, that is a clue. It suggests the publisher values that topic, format, or resource type. Maybe they love data studies. Maybe they like beginner guides. Maybe they are allergic to fluff. Link Intersect gives you the context to create a smarter pitch instead of sending a generic “Dear Webmaster” email that gets deleted with athletic speed.

4. Turn backlink analysis into a workflow

Once the endpoint is connected to your internal system, it becomes easy to run recurring audits, export prospects to CRM tools, enrich results with other metrics, and create reports that show leadership what opportunities exist and why they matter. Suddenly, link building stops being mysterious and starts looking operational.

Best Practices for Using the Link Intersect Endpoint

Choose real SEO competitors, not just business competitors

Your biggest offline rival is not always your strongest organic competitor. Pick sites that rank for the same topics and search intent you care about. If you compare yourself with the wrong domains, your report will be full of irrelevant opportunities and existential confusion.

Use negative targets strategically

The most obvious negative target is your own domain, but you can also exclude sections or properties that would muddy the results. The cleaner the exclusion logic, the more actionable the output becomes.

Keep scope consistent

If one target is a root domain, another is a subdomain, and a third is a single page, your results can become difficult to interpret. That does not mean mixed scopes are always wrong, but it does mean you should know why you are mixing them. Otherwise, you are comparing apples, oranges, and one oddly ambitious kumquat.

Review results manually before outreach

Just because a site appears in the intersect does not mean it is a perfect prospect. Check relevance, editorial quality, spam signals, and context. Moz’s broader link metrics can help, but human review still matters. Google’s guidance is clear that manipulative link tactics can harm visibility, so this endpoint should support editorial outreach, not shortcut schemes.

Watch your anchor strategy

When you do earn links, keep anchor text natural and descriptive. Good anchors help users and search engines understand the destination. Bad anchors sound robotic, over-optimized, or suspiciously like they were written by someone trapped inside a keyword spreadsheet.

Common Mistakes and Troubleshooting Tips

The Moz API V2 Link Intersect endpoint documentation also becomes more useful when you know what can go wrong.

Authentication confusion

Moz’s public materials emphasize authenticated requests and account-linked credentials. If your request fails early, verify the exact authentication method your current account and documentation expect, confirm credentials or token handling, and test with a minimal payload before doing anything ambitious.

Bad input parameters

A 400-level response often points to invalid request formatting or incorrect parameters. Keep your JSON clean, make sure scopes are valid, and do not assume every URL variation is accepted exactly the way you pasted it from a browser tab at 1:12 a.m.

ASCII-only URL problems

Moz’s cheat sheet explicitly calls out a common error: URLs must be ASCII only. If you are working with internationalized URLs or messy exports, normalize them before sending the request.

Rate and plan limits

429 errors are the API equivalent of a bouncer saying, “You have had enough.” If you hit plan or request limits, slow down, respect retry timing, and queue mutating or repeated requests instead of blasting them in parallel. Responsible request pacing is not glamorous, but neither is breaking your integration.

Oversized result expectations

Large prospecting jobs are better handled in batches. Use limits, process results incrementally, and design your application so it can continue from where it left off. That is not just cleaner engineering; it also makes your reporting and QA far easier.

A Smart Workflow for Real-World Use

1. Pick three to five organic competitors for a topic cluster.
2. Set your own domain as a negative target.
3. Require a higher match threshold to surface stronger overlap.
4. Sort by authority or relevance-oriented metrics.
5. Export the results into a review queue.
6. Manually classify prospects into resource pages, editorial mentions, directories, partnerships, and ignore lists.
7. Create content or outreach angles that match the linking pattern you found.
8. Track earned links and rerun the intersect later to measure gap closure.

That workflow is where the endpoint stops being documentation and starts being leverage.

Hands-On Experience With the Moz API V2 Link Intersect Endpoint

Here is the part people do not always say out loud: working with the Moz API V2 Link Intersect endpoint feels less like “running an SEO report” and more like finally cleaning a foggy window. Before you use it, competitor backlink research can feel messy. You know your rivals have links you do not. You know there are opportunities out there. But the process of finding them can be so manual that you start wondering whether the internet was a mistake.

The first pleasant surprise is how quickly the endpoint turns a vague question into a usable dataset. You stop asking, “Where should we build links?” and start asking, “Which of these already-linking publishers is the best editorial fit for our campaign?” That is a much better question. It is also the kind of question that keeps teams from wasting time on prospects that were never realistic.

In practice, the experience gets even better when you pair the endpoint with simple filtering logic. For example, if you only want sources that link to at least two or three competitors, the output usually gets more interesting fast. The junk drops off. The patterns get clearer. You start seeing resource pages, comparison articles, niche blogs, media roundups, and partner pages that clearly live in your content ecosystem. It feels a little like your competitors accidentally left their playbook open on the table. Rude of them, but helpful for you.

There is also a strong “developer relief” factor here. Because the endpoint is request-and-response driven, you can build a workflow around it instead of relying on screenshots and copy-paste marathons. You can route results into a dashboard, blend them with internal scoring, push them into outreach systems, or compare month-over-month movement. That means your backlink strategy gets memory. It stops being a one-time research exercise and starts becoming a process.

Of course, the endpoint is not magic. It will not write your pitch, judge topical relevance perfectly, or stop someone from emailing a terrible outreach template that begins with “Greetings of the day.” Human judgment still matters. You still need content that deserves links. You still need to vet the sites you contact. And you absolutely still need to stay on the right side of search quality guidelines. But the endpoint makes all of that work smarter because it narrows the field to people who are already proven linkers in your niche.

If you are a solo SEO, the biggest win is focus. If you are on a team, the biggest win is repeatability. And if you are the poor soul who has ever had to explain link building ROI to a skeptical stakeholder, the biggest win is clarity. Link Intersect gives you a defendable reason for why certain domains belong in your outreach plan. That is powerful. It is also a lot more convincing than saying, “I had a hunch and a browser with 47 tabs open.”

Final Take

The Moz API V2 Link Intersect Endpoint Documentation is useful because it bridges technical implementation and practical SEO strategy. It shows developers how to structure requests and handle responses, while giving marketers a reliable way to find competitor backlink gaps at scale. Used well, it helps you discover realistic linking opportunities, prioritize outreach, protect your API usage, and keep your link building grounded in relevance instead of wishful thinking.

That is the sweet spot: technical enough to automate, strategic enough to matter, and practical enough to save you from prospecting in the dark like an SEO raccoon rummaging through the web for backlinks.
