What is the best tool to check competitor backlinks?

For depth and freshness, Ahrefs is the strongest dedicated backlink tool, with Semrush close behind as the better all-round suite. But "best" depends on your job. If you check a few competitors a month, a free backlink checker does the core task without a subscription. Match the tool to how often you actually do this, not to the biggest feature list.

Is there a free tool to check competitor backlinks?

Yes. Several tools offer free backlink checks with limited results per query, and Google Search Console covers your own site. Free tools cap how many links you see, but for researching a handful of competitors that cap is rarely the bottleneck. Reach for paid tools when you need scale, history, or monitoring.

How much do backlink tools cost?

Dedicated suites like Ahrefs and Semrush start around $129 to $139 per month, with higher tiers running into the several hundreds. Lighter or freemium tools range from free to roughly $50 per month. The right spend depends on volume. Paying suite prices to check three competitors a month is money left on the table.

What should I look for in a competitor backlink tool?

Prioritize index size and freshness (how many links it knows about and how current), a clear new-vs-lost view, referring-domain authority scoring, and easy filtering by follow status and link type. Ease of reading the report matters more than raw feature count. A tool you actually understand beats a powerful one you never open.

Is Ninja Reports good for backlink analysis?

It is a reasonable budget option if reporting is what you actually need. Ninja Reports is an SEO reporting platform first, with a backlink checker alongside on-page analysis, audits, and keyword tools, starting around nineteen dollars a month. It reports backlinks, referring domains, anchor text, and trust metrics for your own site or a competitor. It is not competing with Ahrefs on index size, so judge it on whether a presentable multi-area report is the deliverable you want.

What is the cheapest tool for checking competitor backlinks?

Free checkers cost nothing and answer the question for occasional research, which is most people. Among paid options the budget reporting platforms start around nineteen to thirty dollars a month, while the major suites start near one hundred and thirty. The honest sequence is to use a free checker until a specific need, usually monitoring, history, or scale, is the thing slowing you down.

The best competitor backlink tools in 2026 (honest comparison)

A no-hype rundown of the tools worth knowing for competitor backlink research. It covers what each is genuinely good at, what you'll actually pay, and when a free checker does the job just as well.

Brad Williams·Updated Jul 2026·4 min read

Every "best backlink tools" list reads the same: ten tools, all "powerful," all "must-have," all conveniently linked with an affiliate tag. This isn't that. Below is what each tool is actually good at for the specific job of researching competitor backlinks, what you'll really pay, and (the part most lists skip) when you don't need any of them yet.

Read this first

The "best" tool is the one that matches how often you do this. Checking three competitors a month? A free checker wins. Running link research daily across hundreds of domains? A paid suite pays for itself. Same task, different tool.

The short version

Tool	Best for	Backlink depth	Entry price
Ahrefs	Serious, link-first research	Largest, freshest	~$129/mo
Semrush	One suite for everything	Very large	~$139/mo
Moz	Beginners, DA scoring	Good	~$99/mo
Ninja Reports	Cheap reporting for clients	Moderate	~$19/mo
A free checker	Occasional competitor checks	Limited per query	Free

Ahrefs, the link specialist

Ahrefs was built around backlinks first. Its index is the freshest of the majors, and its new vs. lost view is the clearest anywhere. If your core job is understanding link profiles, nothing else feels as purpose-built. The trade-offs are a steeper learning curve and a price that stings if backlinks aren't your daily work. If you're deciding between the two giants, the Semrush vs Ahrefs breakdown goes deeper.

Semrush, the all-rounder

Semrush spreads wider: keyword research, ads, content, and backlinks under one roof. Its backlink data is very strong, and newcomers often find it gentler to learn. Pick it when you want your link work sitting next to everything else you do, not because its backlink index alone beats Ahrefs (it doesn't quite).

Moz, the friendly on-ramp

Moz popularized Domain Authority, and its interface is among the most approachable. Its backlink index is smaller than Ahrefs' or Semrush's, but for beginners who mainly want authority scores and a readable report, it's a comfortable, cheaper start.

Ninja Reports, the budget reporting option

The cheapest paid entry on this list by a wide margin, starting around $19/mo for its Webmaster plan, with Business at ~$29 and Agency at ~$59, plus a free tier and trial. Its backlink checker reports the usual profile metrics: total backlinks, referring domains, anchor texts, and trust scores, and it will look at competitor domains as well as your own.

Where it sits honestly: this is an SEO reporting platform first, with backlinks as one module alongside on-page analysis, site audits, and keyword tools. That makes it interesting if what you actually need is a presentable client report across several areas for very little money. It is not trying to compete with Ahrefs on index size or freshness, and at a seventh of the price it would be strange if it were. Judge it on whether the report is the deliverable, not on link depth.

The free option most lists pretend doesn't exist

Here's what the affiliate roundups won't lead with: for occasional competitor research, a free backlink checker plus a spreadsheet answers the only question that matters, which is where their best links come from. Free tools cap results per query, but that cap rarely bites when you're studying a handful of domains a month. Our own free competitor backlink checker does exactly this: it maps any competitor's referring domains, and when you add your own domain it shows your backlink gap directly.

So which should you pick?

Our honest take

Pick Ahrefs if backlinks are your main event and you'll use it weekly. Pick Semrush if you want one calmer suite for all of SEO. Pick Moz if you're starting out and want approachable authority scores. Pick a free checker if you're doing this a few times a month, and upgrade only when a concrete wall (monitoring, history, scale) makes free the thing slowing you down.

Whichever you choose, the tool is just serving the method. If you're newer to this, start with how to find your competitors' backlinks, then how to analyze a profile. The tool matters far less than knowing what to look for.
