Does Ahrefs Get Backlinks From Majestic?

In summary

No, Ahrefs does not get its backlink data from Majestic. Ahrefs uses its own proprietary crawler, AhrefsBot, which is one of the most active web crawlers in the world, while Majestic relies on its own independent crawler, MJ12bot.

Does Ahrefs get backlinks from Majestic is a question I hear often from SEO professionals who are trying to understand why their link reports look so different across various platforms. When you are deep in the trenches of link building, it might seem like these giants are sharing a massive, secret database behind the scenes, but the reality is quite the opposite.

I have spent years navigating the nuances of these tools, and I can tell you that the “data wars” in the SEO industry are real. These companies invest millions of dollars into their own infrastructure precisely so they don’t have to rely on anyone else.

The Independent Architecture of Ahrefs and Majestic

To understand if Ahrefs gets its data from a competitor, we first have to look at how these tools actually “see” the internet. Think of each tool as a digital librarian. Ahrefs has its own librarian (AhrefsBot) who walks through every shelf of the internet library, while Majestic has a different librarian (MJ12bot) doing the same thing.

Ahrefs operates one of the most sophisticated web crawling operations on the planet. In fact, AhrefsBot is consistently ranked as the second most active crawler behind Google. This independence is a core part of their value proposition. They don’t want to buy data; they want to own the source.

How Ahrefs Collects Its Data

Proprietary Crawling: AhrefsBot visits over 8 billion pages every 24 hours.
Infrastructure: They maintain a massive server cluster that processes and indexes this information in real-time.
Historical Storage: They keep a record of “Live,” “Recent,” and “Historical” links, which are all generated by their own internal scans.

Why You Might Think They Share Data

It is easy to get confused when you see the same link pop up in both tools. If I publish a guest post on a high-traffic site, Ahrefs will show it, and Majestic will show it too. This isn’t because they are sharing a spreadsheet; it’s because both of their bots are extremely efficient at finding new content.

When asking “does Ahrefs get backlinks from majestic,” the overlap you see is simply a testament to the fact that both tools are very good at their jobs. If they didn’t show the same high-profile links, one of them wouldn’t be worth the subscription fee.

Key Differences in Data Sources

Feature	Ahrefs Approach	Majestic Approach
Primary Bot	AhrefsBot	MJ12bot
Index Focus	Freshness and General SEO	Historical depth and Trust
Data Source	100% Independent Crawl	100% Independent Crawl
Primary Metric	Domain Rating (DR)	Trust Flow (TF)

Does Ahrefs Get Backlinks From Majestic for Its Index?

I can say with 100% certainty that Ahrefs does not use Majestic as a data source for its backlink index. Ahrefs has built its entire reputation on having the “freshest” data. If they were waiting for Majestic to crawl a site and then “buying” that data, Ahrefs would always be slower than their competitor. In the SEO world, speed is everything.

In my experience, the only time these tools “interact” is when a user exports a CSV from one and uploads it to the other. But as far as the software’s native database goes, they are strictly competitors, not collaborators.

Understanding the “Backlink Gap”

Since they don’t share data, you will often notice a “gap.” For example, Ahrefs might show 500 linking domains while Majestic shows 420. This happens because:

Crawl Frequency: Ahrefs might crawl a specific niche more frequently than Majestic.
Bot Access: Some website owners block AhrefsBot but allow MJ12bot (or vice versa) in their robots.txt file.
Filtering: Each tool has different rules for what counts as a “junk” link. Ahrefs is quite aggressive at filtering out low-quality spam that it doesn’t think adds value to the report.

Common Mistakes When Comparing Data

Assuming the higher number is “better”: A tool that shows 10,000 links isn’t necessarily better than one showing 5,000 if the extra 5,000 are all dead or toxic.
Comparing different timeframes: Comparing a “Fresh” index in Majestic to a “Historical” index in Ahrefs will always yield confusing results.
Ignoring the metric logic: Domain Rating (DR) and Trust Flow (TF) are calculated using different math. A high DR doesn’t always mean a high TF.

Does Ahrefs Get Backlinks From Majestic Metrics?

While they don’t share link data, do they share metrics? No. Ahrefs uses its own proprietary algorithm to calculate Domain Rating (DR) and URL Rating (UR). These are based on the strength and quantity of the backlinks they have found.

Majestic uses Trust Flow (TF) and Citation Flow (CF). Their Trust Flow is unique because it’s based on a “seed set” of manually reviewed, trusted sites. Ahrefs doesn’t have a direct equivalent to this topical trust system, which is why many link builders actually use both tools simultaneously.

Step-by-Step: How to Verify Your Backlink Profile

Check Ahrefs Site Explorer: Enter your URL to see the live links found by AhrefsBot.
Cross-Reference with Majestic: Use the “Fresh Index” to see if MJ12bot has discovered links Ahrefs missed.
Evaluate Trust: Use Majestic’s Trust Flow to see the quality of the neighborhoods linking to you.
Audit for Disavow: Use the Ahrefs “Broken Backlinks” report to see where you are losing equity.
Merge Data: If you are doing a deep audit, export both lists into a single spreadsheet and remove duplicates to see the “true” total.

Pros and Cons of Independent Data Crawling

Pros:

Redundancy: If one bot is blocked by a specific hosting provider, the other might still get through.
Diverse Perspectives: You get two different algorithmic “opinions” on how strong a website is.
Competition: It forces both companies to constantly improve their crawling speed and index size.

Cons:

Cost: You often have to pay for two expensive subscriptions to get the full picture.
Data Fragmentation: It can be time-consuming to reconcile two different reports for a client.

FAQs

Can I see Majestic data inside the Ahrefs interface?

No. There is no official integration between the two. If you see Majestic metrics in an Ahrefs-related report, it is likely because a third-party browser extension or a custom API dashboard is pulling from both sources.

Why does Majestic find links that Ahrefs misses?

Every bot has a different “crawl path.” Majestic’s MJ12bot might follow a specific link trail that AhrefsBot hasn’t prioritized yet. Additionally, Majestic’s “Historic Index” keeps data for much longer than Ahrefs’ standard view.

Is Ahrefs more accurate than Majestic?

“Accuracy” is subjective in SEO. Ahrefs is generally considered to have a more “active” and “live” index of the modern web. However, Majestic is often cited as the gold standard for analyzing the “trust” and topical relevance of a link profile.

Do I need both tools if they don’t share data?

If you are a professional link builder or a high-level SEO consultant, yes. Using both ensures you aren’t missing a significant portion of a competitor’s link profile. For small business owners, Ahrefs is usually sufficient as an all-in-one tool.

Does Ahrefs use Google’s data?

No. Ahrefs (and Majestic) are “blind” to Google’s actual index. They try to mimic Google’s behavior, but they don’t have access to Google’s private database. The only tool that shows you “Google’s data” is Google Search Console.

What should I do if the backlink counts are drastically different?

Check your robots.txt file. It is possible you are accidentally blocking one of the bots. If the bots aren’t blocked, look at the “referring domains” rather than the total link count, as this is a more stable metric for comparison.

I hope this clears up the mystery of whether Ahrefs gets its power from its competitors. In the world of SEO, independence is the ultimate competitive advantage. By running their own crawlers, these tools provide us with the checks and balances we need to make informed decisions for our websites.

Relying on a single source of truth is risky. By understanding that these are two separate entities with two separate “brains,” you can leverage the strengths of both to build a more robust, authoritative digital presence.
