How to Check Backlinks: 6 Free & Paid Tools for 2026 (B2B Guide)

How to Check Backlinks: 6 Free & Paid Tools for 2026 (B2B Guide)

To check your backlinks, pair Google Search Console (free — it shows the links Google actually attributes to you) with one paid tool like Ahrefs or Semrush for referring-domain depth, authority scores, and anchor data. That two-tool combination is enough for most companies. It matters more than usual in Indonesia, where roughly 220 million people are online and Google owns well over 90% of search — so in a market like Jakarta, your link profile often decides page one versus page three.

Backlinks remain one of Google's core ranking signals — a stance the company has held publicly since the Penguin update in 2012 began penalising manipulative links. For any brand competing in Indonesia's crowded search results, monitoring your backlink profile is no longer optional; it is table stakes.

If you are a marketing director or CMO at a US, Singaporean, or Australian company evaluating an Indonesia-based agency partner — or entering the market directly — this guide is written for you. You do not need to speak Bahasa Indonesia or know the local players to read a link profile. You do need to understand what "strong digital authority" actually looks like before you sign a retainer or approve a market-entry budget.

Short answer: Use Google Search Console (free, shows the links Google genuinely recognises) as your foundation, then enrich it with a paid tool — Ahrefs, Semrush, or Moz — for far deeper data on referring domains, authority, and anchor text. One free tool plus one paid tool covers the vast majority of businesses. You do not need every subscription at once.

Key Takeaways:

• Google Search Console is free and shows the links Google actually counts, but its data is shallow — it is not the full picture of your backlink profile.
• Paid tools (Ahrefs, Semrush, Moz, Majestic) win on depth: referring domains, authority scores, anchor text, and toxic-link detection.
• Raw backlink count means almost nothing without context — domain relevance, authority, and link placement matter far more.
• Before you subscribe, define the goal of the audit: monitoring your own profile, studying competitors, or cleaning up harmful links.
• Link authority is built systematically and gradually — like building a premium brand from zero — not bought in a single "backlink package".

Why a Backlink Audit Comes Before Your SEO Investment

Imagine pouring budget into SEO without knowing who links to your site. It is like buying a used car without ever checking the engine. Backlinks are third-party votes that tell Google your content is worth citing — and Google treats high-quality links as a form of endorsement.

There are three practical reasons a backlink audit belongs at the start of an engagement, not the end. First, you need a baseline: how many unique domains already reference your site today. Second, you need to detect harmful links before they drag your rankings down. Third, you need a competitor map — where rivals earn links that you have not yet won.

For a brand competing in a narrow, high-value segment, the backlink gap is often the difference between page one and page three. A competitor that started building links from local media and industry directories years earlier holds an advantage you cannot close simply by publishing more articles.

The foreign-brand angle: why this is sharper in Indonesia

When a premium brand enters Indonesia from zero recognition, the first question the marketing team asks is rarely "how many ads should we run?" It is "how strong is our digital footprint compared with competitors that have been trusted here for decades?"

We saw this first-hand supporting the market entry of a premium automotive brand, XPENG, a Chinese EV maker launching into a market where established Japanese and European marques had held trust for a generation. Most of that trust footprint is built from links: who mentions, references, and links to your brand across the Indonesian web. A brand that is a household name in its home market can arrive in Jakarta with almost no local link authority — and Google's Indonesian results will treat it accordingly.

This is the trap for foreign entrants. Global brand equity does not transfer to local search authority. A backlink audit is how you measure the real gap before you commit budget — and it is one of the first things a competent Indonesian SEO agency should show you, with numbers, in a pitch. If a prospective partner cannot walk you through your referring-domain profile versus two local competitors, that is a signal.

6 Tools to Check Your Backlinks (Free & Paid)

No single tool is perfect. Each has a different index size, metric set, and philosophy. Here are the six most relevant options for the Indonesian market in 2026, from fully free to fully paid.

1. Google Search Console (Free)

This is the mandatory starting point. Open the Links menu, then view the Top linking sites report to see which domains link to you most. The upside is clear: free, unlimited, and it shows the links Googlebot genuinely associates with your site — data that directly informs rankings. The limitation is equally clear: the report is shallow, shows no authority scores, and covers only part of your backlink profile. Treat Search Console as your foundation, not the complete picture.

For a foreign brand, one caveat: Search Console only reflects links to a property you have verified. If your Indonesian market entry runs on a country subdomain or a separate .co.id domain, verify that property — links to your global .com will not appear.

2. Ahrefs (Limited Free + Paid)

Ahrefs is the industry reference because its index is enormous — the company reports tens of trillions of links from hundreds of millions of referring domains, with a crawler processing billions of pages per day. The free Backlink Checker shows top links, Domain Rating, referring-domain count, and anchor text. For your own site, Ahrefs Webmaster Tools gives fuller data at no cost. The full plan starts around $129/month. For agency-grade competitor research in a market you do not know, Ahrefs is usually the single most useful paid subscription.

3. Semrush (Paid, Trial Available)

Semrush's strength is two features: Backlink Gap, which compares your link profile against up to four competitors at once, and Backlink Audit, which assigns a toxic score to suspicious links. If your priority is closing the distance on rivals — the usual situation for a new market entrant — this comparison tooling is worth the cost, which starts around $139/month.

4. Moz Link Explorer (Limited Free + Paid)

Moz popularised Domain Authority (DA), now common vocabulary among SEO practitioners. Its added value is Spam Score, which estimates how likely a domain is to be spammy. If you want to quickly judge whether a potential link is safe or risky — say, when vetting the local directories an agency proposes — the DA-plus-Spam-Score combination is very practical.

5. Ubersuggest (Limited Free + Paid)

If your team is just starting and needs an interface that will not overwhelm them, Ubersuggest is approachable. Its backlink features are simple and easy to read. The data is not as deep as Ahrefs or Semrush, but for an initial review on a limited budget, it gets the job done.

6. Majestic (Paid)

Majestic is the link-quality specialist. Its two metrics — Trust Flow (how trustworthy the linking source is) and Citation Flow (how many links there are) — are often read together to spot profiles that are large in volume but fragile in quality. It is well suited to deep analysis when raw numbers alone are not enough.

The Backlink Metrics You Must Read (Not Just the Count)

The most common mistake we see when auditing client sites: fixation on the total number of backlinks. Big numbers look impressive but often mislead. A thousand links from junk domains are worth less than ten links from relevant industry media.

Four metrics matter far more than raw count:

1. Referring domains — how many unique domains link to you. Ten links from one site count as a single vote; ten links from ten different sites are far stronger. This is the first number to check in any audit.
2. Source domain authority (DR in Ahrefs, DA in Moz) — links from high-authority sites pass more "trust". A single link from a national news outlet outweighs dozens from obscure blogs.
3. Topical relevance — a link from a same-industry site is worth more than a random, contextually unrelated one. For a foreign brand, relevance also means local relevance: an Indonesian industry publication carries weight that a foreign-language link, however authoritative, may not for local queries.
4. Anchor text & attributes — a natural spread of anchor text is a healthy signal; an unnatural over-optimisation of exact-match keywords is a classic footprint of manipulative link building and a red flag Google acts on.

Read together, these four turn a raw list of links into an actual verdict on authority and risk. A profile with 50 referring domains that are relevant and high-authority beats one with 500 that are irrelevant and spammy — every time.

How to Run Your First Backlink Audit (A Simple Workflow)

If you are evaluating a market or a partner rather than doing SEO yourself day to day, you still want a repeatable read. Here is the minimum viable workflow:

1. Establish the baseline in Search Console. Verify the correct property and export the Top linking sites report. This is what Google actually sees.
2. Enrich with one paid tool. Pull referring domains, DR/DA distribution, and anchor text. Note the ratio of high-authority to low-authority domains.
3. Run a competitor gap. Choose two local competitors and compare referring domains. The links they have and you do not are your opportunity list.
4. Flag toxic links. Use a toxic/spam score to isolate risky links. Decide whether to disavow — and remember that disavowing is a scalpel, not a hammer.
5. Translate findings into a plan. The audit is only useful if it produces a prioritised list of link opportunities and risks. A good agency delivers this as a deliverable, not a data dump.

That is the whole loop. It is not complicated — but the discipline of doing it before spending is what separates ROI-positive SEO from budget burned on content nobody links to.

FAQ

Do I really need a paid backlink tool, or is Google Search Console enough?

Search Console is enough to see the links Google attributes to you, but it shows no authority scores, no competitor data, and only part of your profile. For any competitive decision — market entry, agency selection, or a link-building budget — one paid tool (Ahrefs or Semrush) is worth it. The free plus one-paid combination is the sweet spot for most companies.

As a foreign brand entering Indonesia, why does my backlink profile matter so much?

Global brand equity does not transfer to local search authority. Google's Indonesian results rank based on signals it sees in that market, and much of that is local links. A brand famous elsewhere can arrive in Jakarta with almost no local link authority — and rank accordingly. Auditing the gap before you invest is how you avoid overestimating your starting position.

How many backlinks do I need to rank in Indonesia?

There is no magic number, and count is the wrong question. Referring-domain quality and relevance matter more than volume. Ten links from relevant, authoritative Indonesian sites will typically outperform hundreds of low-quality ones. Benchmark against the specific competitors ranking for your target keywords rather than chasing an absolute figure.

How can I tell if an Indonesian SEO agency is doing legitimate link building?

Ask to see the referring domains they have earned for past clients, the anchor-text distribution, and the Trust Flow or Domain Rating of those sources. Legitimate link building shows relevant, varied, authoritative domains built gradually. Warning signs: sudden spikes, exact-match anchor over-optimisation, or a refusal to name sources. A credible partner will walk you through a live profile.

What are toxic backlinks and should I worry about them?

Toxic backlinks come from spammy, irrelevant, or manipulative sources and can drag rankings down or, in extreme cases, trigger a penalty. Tools like Semrush's Backlink Audit or Moz's Spam Score help identify them. Most sites do not need aggressive disavowing — but you should audit for toxic links, especially if you inherited a domain or worked with a low-quality provider previously.

How often should I check my backlink profile?

For an active site, a monthly monitoring pass and a deeper quarterly audit is a sensible cadence. If you are running or evaluating a market-entry campaign, check more frequently in the first few months, when new links (and potential negative-SEO attacks) appear fastest.

The Bottom Line

Checking backlinks is not a technical chore to delegate and forget — it is a decision tool. For a foreign brand weighing an Indonesian market entry or an agency partner, the backlink audit answers the question that actually matters: how strong is our authority here, really, compared with the competitors already winning these searches?

Start free with Google Search Console, add one paid tool for depth, and read referring domains and authority over raw count. Authority, like a premium brand, is built systematically and gradually — never bought in a single package. Measure the gap first; then invest against it.
