## TL;DR — the short version

- **Free and enough for most sites:** Ahrefs Webmaster Tools, now branded **Ahrefs Free** — full Site Explorer backlink data on any domain you verify, permanently
- **Google's own view, also free:** the Search Console Links report — slow, no alerts, but it is what Google actually sees
- **Cheapest paid entry:** Ahrefs Starter at $29/month, or RankBuddy at $29/month if you want the check to run on a schedule and arrive interpreted
- **Deepest dedicated link index:** Majestic from $49.99/month, with Trust Flow and historical link data
- **Best if you already run a suite:** Semrush at $139.95/month or SE Ranking from $129/month

**The part most articles get wrong:** almost every backlink alert is noise. Out of everything a backlink monitor can tell you, only three signals are worth an interruption — and one popular feature, automatic "toxic link" disavowing, is actively dangerous. Details below.

![The six automated SEO monitoring jobs, including backlink monitoring, and the schedule each one runs on](https://rankbuddy.io/i/0ce6b2ba-7706-4534-b012-61293c4a043e)

## What backlink monitoring actually catches

A backlink monitor re-crawls the web on a schedule and diffs the result against last time. It reports three kinds of change:

- **New links** — someone linked to you since the last crawl
- **Lost links** — a link that existed before and does not now
- **Changed links** — followed became nofollow, the anchor text changed, or the linking page moved

That is genuinely useful. What it cannot tell you is whether any of it mattered. No index knows which of your pages carry revenue, and no "toxic score" knows what Google thinks. Backlink monitoring is a change feed; the judgment is still yours — which is the same problem the whole category has, and the reason our guide to [automated SEO monitoring](/blog/automated-seo-monitoring) spends more time on what to ignore than on what to collect.

**One thing to internalise before you buy anything:** every tool's link count will differ, sometimes by a lot. They run different crawlers with different budgets and different rules about what counts as a link. A domain showing 400 referring domains in one tool and 260 in another is not a bug. Pick one tool, and judge trends inside it rather than comparing absolute numbers across tools.

## The only three alerts worth having

1. **A lost link from a page that sends you traffic or authority.** Not "a lost link" — a lost link that mattered. Set the threshold at your top referring domains, not the whole profile.
2. **A sudden spike in new links you did not earn.** Fifty new referring domains overnight, all from the same footprint, is either a negative-SEO attempt or an agency you hired doing something you should know about.
3. **A followed link on a key page turning nofollow.** This is the quiet one. Nothing disappears, so nothing looks broken, and the equity stops flowing.

Everything else — the daily count, the "authority score" wobbling by two points, the routine churn of scraper sites appearing and vanishing — is a metric to look at monthly, not an alert. If you cannot say what you would *do* when a number moves, it should not be allowed to interrupt you.

## 1. Ahrefs Webmaster Tools / Ahrefs Free — free, and the same index as the paid plans

![Ahrefs Webmaster Tools, now branded Ahrefs Free, giving verified site owners free backlink and site audit data](https://rankbuddy.io/i/93214bbe-8277-48c0-aae5-bc6df2dc1a51)

| | |
| --- | --- |
| **Price** | Free forever for verified site owners |
| **Covers** | Your own verified domains |
| **Key edge** | Ahrefs' link index at $0 |

Verify a domain through Search Console or an HTML file and you get Site Explorer on it permanently — referring domains, new and lost links, anchor text, and the Site Audit crawl alongside it. This is not a trial and it does not expire.

Ahrefs is currently retiring the "Webmaster Tools" name; its own page now carries a notice that Ahrefs Webmaster Tools **is now Ahrefs Free**. Same free access, broader framing. Any comparison article that does not mention this has not looked at the product recently.

**Where it stops:** your domains only. No competitor link research, and no alerting worth the name — you go and look.

## 2. Google Search Console Links report — Google's own answer

| | |
| --- | --- |
| **Price** | Free forever |
| **Covers** | Your verified properties |
| **Key edge** | It is what Google sees, not a third-party crawl |

Every other tool on this page is guessing at what Google knows. This one is not. The Links report shows top linking sites, top linked pages and top anchor text as recorded by Google.

**Where it stops:** it updates slowly, shows a sampled and capped view, and has no notion of "new" or "lost" over a period you choose. Treat it as a reference check when a third-party tool tells you something surprising — not as your monitor.

## 3. RankBuddy — the check that runs itself and arrives interpreted

![RankBuddy's weekly monitoring workflow, scheduled, with the finished report emailed on completion](https://rankbuddy.io/i/25adb0cb-30b3-4f35-9995-a2428bc68a95)

| | |
| --- | --- |
| **Price** | Free to start, from $29/month |
| **Covers** | Your domain and competitors, on a schedule you set |
| **Key edge** | The weekly check happens without you remembering to do it |

The gap the free tools leave is not data — it is the recurring five minutes nobody spends. RankBuddy runs [backlink analysis](/features/backlink-analysis) and a weekly Domain Rating check as scheduled Employee Workflows, using Ahrefs and DataForSEO data underneath, and what lands in your chat is what moved and whether it deserves attention.

You can also just ask it a question about the profile in plain language and get a follow-up answer, which no dashboard supports. Pricing is $29 Starter, $49 Pro, $79 Scale, one website per plan.

**Where it is honest about its limits:** there is no proprietary Ahrefs-scale crawler behind it — the link data comes from Ahrefs and DataForSEO. If you want to interrogate a 15-year link history yourself, buy the index directly.

## 4. Ahrefs Starter — the cheapest way into competitor link data

| | |
| --- | --- |
| **Price** | $29/month, monthly billing only |
| **Covers** | Any domain, not just yours |
| **Key edge** | Ahrefs' index without the $129 entry ticket |

The moment you need to look at links pointing at somebody else, the free tier stops and this is the cheapest honest door in. Ahrefs' current published ladder runs Starter $29, Lite $129, Standard $249, Advanced $449, Enterprise $1,499 — and Starter is deliberately capped to protect the tiers above it.

Worth knowing while you are on that page: Ahrefs' AI-visibility product, **Brand Radar**, starts at $199/month and is separate from all of the above. Backlink monitoring and AI-visibility monitoring are priced as different products almost everywhere.

## 5. Majestic — the specialist index

| | |
| --- | --- |
| **Price** | Lite $49.99/month, Pro $99.99/month, API $399.99/month |
| **Covers** | Any domain |
| **Key edge** | Trust Flow, Topical Trust Flow, and deep historical link data |

Majestic does one thing and has done it for longer than most of this list has existed. Its Fresh and Historic indexes, Trust Flow scoring and link-context reporting are still the reference for people who work links seriously. Pro adds the Historic Index, backlink history, Clique Hunter and email alerts. Prices can be shown in dollars, pounds or euros, exclude VAT, and Lite and Pro carry a 7-day money-back guarantee for new customers.

**Where it stops:** it is a link tool, not an SEO suite. No rank tracking to speak of, no content tooling, and the interface assumes you know what Trust Flow is for.

## 6. Semrush — backlink audit inside the suite

| | |
| --- | --- |
| **Price** | $139.95/month (Pro) |
| **Covers** | Any domain |
| **Key edge** | Link data sitting next to rank, technical and competitive data |

If you already pay for Semrush, its Backlink Audit and Backlink Gap tools are perfectly good and you do not need another subscription. The Backlink Gap view — which domains link to three competitors but not to you — is the single most useful link-building input in the suite.

**One caution:** Semrush's Backlink Audit surfaces a "toxic score" and offers to build a disavow file from it. Read the next section before you use that button.

## 7. SE Ranking — backlink monitoring with client reporting attached

| | |
| --- | --- |
| **Price** | From $129/month (Core), $279/month (Growth) |
| **Covers** | Several client domains on one plan |
| **Key edge** | White-label reports that include the link data |

For a small agency, the value is not the link index — it is that new and lost links land in the same PDF as rankings and site health, branded for the client. It also covers multiple projects on one subscription, which is what makes the per-site maths work.

## The disavow trap

This is the part of backlink monitoring that costs people rankings, so it is worth being blunt.

Several tools score your links for "toxicity" and offer to generate a disavow file from that score. Those scores are vendor heuristics. Google does not publish one, does not use theirs, and has said repeatedly that it ignores the overwhelming majority of low-quality links on its own. Its guidance for the disavow tool is narrow: use it if you have a manual action, or if you genuinely believe you have a link-spam problem you caused.

Bulk-disavowing on a third-party score means telling Google to ignore links it was probably counting in your favour. That is not a reversible experiment on a useful timescale.

**The safe default:** monitor links, do not auto-disavow anything, and if a spike of junk appears, check Search Console for a manual action before you touch the disavow file. If there is no manual action, there is usually nothing to do.

## How this fits with the rest of monitoring

Backlink monitoring is one of four jobs, and on its own it will not tell you why traffic moved. The full picture — search performance, rankings, technical changes and AI visibility — is laid out in our guide to [automated SEO monitoring](/blog/automated-seo-monitoring), and if you are choosing a tool for the whole stack rather than links specifically, we compared those in [best automated SEO monitoring tools](/blog/best-automated-seo-monitoring-tools).

Two adjacent reads worth having: [Domain Rating vs Domain Authority](/blog/domain-rating-vs-domain-authority) explains what the score your monitor reports actually measures, and [how to check Domain Rating](/blog/how-to-check-domain-rating) covers the practical version.

## Bottom line

For your own site, backlink monitoring is a solved problem and it costs nothing: verify in Ahrefs Free, cross-check anything surprising in the Search Console Links report, and look once a week. Pay for a tool when you need to watch domains you do not own, or when the weekly look is the thing that keeps not happening — that is the $29 problem, not a data problem.

And whatever you buy, leave the disavow file alone.

## Frequently asked questions

### What is a backlink monitoring tool?

A backlink monitoring tool re-crawls the web on a schedule and reports which links to your site are new, which have disappeared, and which have changed — for example a followed link turned nofollow, or the linking page was deleted. It is one component of automated SEO monitoring, alongside rank, technical and AI-visibility monitoring.

### Is there a free backlink monitoring tool?

Yes, two. Ahrefs Webmaster Tools — now called Ahrefs Free — gives you Site Explorer backlink data on any domain you verify, permanently, at no cost. Google Search Console's Links report is also free and shows Google's own view of who links to you, though it updates slowly and gives you no alerting.

### How often should I check my backlinks?

Weekly is enough for almost every site, and monthly is fine for a small one. Backlink profiles move slowly, and link indexes refresh on their own schedule, so a daily backlink alert mostly reports index churn rather than real change. The exception is right after a link-building campaign or a site migration, when a daily check for a week or two is justified.

### Should I disavow spammy backlinks I find?

Usually not. Google says it ignores most low-quality links automatically, and its own guidance is that the disavow tool is for cases where you have a manual action or genuinely believe you have a link-spam problem you caused. Disavowing in bulk on a tool's "toxic" score is the most common way people damage their own link profile, because those scores are vendor heuristics, not Google's judgment.

### What does it mean when a backlink is lost?

It can mean the linking page was deleted, the link was removed from it, the page stopped being crawlable, or the tool simply has not re-crawled it recently. Check the linking URL yourself before acting. A lost link only matters when it pointed at a page you actually care about ranking, and even then the fix is usually an email, not a panic.

### Do I need a paid backlink monitoring tool?

Only if you need to watch domains you do not own — competitors, or client sites you cannot verify. Ahrefs Free covers your own domains completely, and it is the same index behind Ahrefs' paid plans. Pay when you need competitor link gaps, historical data, or alerts routed to a team.
