What is link building and why does it matter for SEO?

Link building is the process of getting links (backlinks) from other websites that point to yours. Google treats backlinks as "votes of confidence": the more authoritative websites link to you, the more Google trusts that your site is relevant and credible. Backlinks are still an important ranking signal for Google, alongside the quality and relevance of your content.

What is the difference between a quality backlink and a spammy one?

A quality backlink comes from a topically relevant website with a high DA/DR and real organic traffic, is editorial (not paid for) and uses natural anchor text. Spammy backlinks come from PBNs (Private Blog Networks), link-farm directories, automated blog comments and irrelevant websites, or use over-optimised anchor text. Spammy backlinks can lead to a Google Manual Action penalty that takes months to recover from.

How do I get backlinks from Indonesian online media?

There are two approaches. (1) Digital PR: create original data content (surveys, industry research) that is useful to journalists, then distribute it through press releases and media outreach. (2) A platform that connects journalists with expert sources: respond to journalists' requests for expert comment. A single piece of coverage in national media such as Kompas, Detik or IDN Times can be worth far more than a large number of ordinary backlinks.

What is guest posting and how do you do it?

Guest posting means writing an article to be published on another blog or website in return for a backlink to your site. To do it well: (1) find blogs in your niche by searching Google for "tulis untuk kami [industry]" or "write for us [niche]", (2) pitch a topic the blog has not covered yet that is relevant to its audience, and (3) write high-quality content. Do not treat guest posts as a low-effort way to get links.

How many backlinks do you need to rank on Google?

There is no fixed number, and quality matters far more than quantity. A low-competition keyword can sometimes rank with only a few quality backlinks, while a competitive keyword usually needs far more. Check the competitors in positions 1–3 with Ahrefs or Moz (both have limited free versions) to see the backlink profile you need to beat.

Is buying backlinks safe for an Indonesian business website?

It is not safe and we do not recommend it. The spam policies in Google Search Essentials (formerly the Webmaster Guidelines) explicitly prohibit buying or selling links that pass ranking signals. The risks are a Manual Action penalty (your website disappears from search results), an algorithmic penalty (rankings drop sharply) and permanent damage to your domain's reputation. Bought links often come from PBNs or link farms that do more harm than good.

What is broken link building and how do you do it?

Broken link building means finding dead links on other websites and offering your content as a replacement. The steps: (1) use Ahrefs or Check My Links (a Chrome extension) to find broken links on industry websites, (2) create or identify relevant content of yours that could replace them, and (3) contact the website owner, point out the dead link and offer your content. Site owners are usually more receptive to this than to ordinary cold outreach, because you are helping them fix a problem.

Link Building Strategies for Indonesian Sites

An effective link building strategy is how you raise your website's domain authority in Google's eyes, especially in 2026, when the algorithm is better than ever at telling quality backlinks from link spam. This article explains how to build a strong, natural backlink profile that stays clear of Google Penguin penalties, written specifically for Indonesian websites.

Why does link building still matter in 2026?

With all the noise around Google's AI Overviews, many people question whether link building is still relevant. It is: quality backlinks remain one of Google's strongest ranking factors. Research from Ahrefs shows that pages with more quality backlinks consistently rank higher than competitors with similar content but a weak backlink profile.

What has changed is the quality required. In 2026, 10 backlinks from relevant, high-authority websites are worth far more than 1,000 backlinks from spam directories or low-grade PBNs. Google keeps getting better at detecting and discounting unnatural links, and it can issue manual penalties that remove a website from search results altogether.

8 effective link building strategies for Indonesian websites

1. Guest posting on authoritative Indonesian websites

Guest posting, where you write an article for someone else's website and get a backlink in return, is still the most effective and safest link building strategy. The key is to choose websites that are relevant to your niche, have a high DA/DR and are genuinely read by real people.

In Indonesia, guest post opportunities usually come from business and technology blogs and from niche media that run a contributor section. Before you pitch, read their guidelines and make sure your topic suits their audience.

Guest post tips for earning quality backlinks:

Write articles with real informational value rather than thinly veiled promotion
Place the link to your website within relevant content, not only in your author bio
Vary your anchor text: branded (your website's name), partial-match keywords and generic phrases
Build a relationship with the editor before you pitch, for example by engaging with their social media first

2. Linkable assets: content worth citing

The most natural way to earn backlinks is to create content so useful that other people choose to cite and link to it. The content types with the highest link potential:

Original data and surveys: Research with unique data that is not available elsewhere. For example: “Indonesian Website Development Cost Survey 2026”
Infographics: Data visualisations that are easy to share and embed on other websites
Comprehensive guides: Pillar pages of 3000+ words that become the definitive reference on a topic
Free tools and calculators: A website cost calculator or a digital ad ROI estimator. People tend to link to useful tools
Free templates: Contract, proposal and SOP templates that people can use straight away

3. Digital PR: press releases and media coverage

Coverage from leading Indonesian online media (Kompas, Detik, CNN Indonesia, IDN Times, Bisnis.com) brings backlinks with very high authority. The approach is to create a newsworthy story: a business milestone, a unique survey, or an expert view on a current issue in your industry.

How to start digital PR for a local business:

Write a professional press release with a strong news angle
Identify the reporters and editors who cover your niche and contact them personally
Sign up to a platform that connects journalists with expert sources so you can be quoted
Follow relevant industry discussions on Twitter/X and add useful comments

4. Broken link building

Broken link building means finding links on other people's websites that point to error pages (404), then offering your content as a replacement. It works well because you help the site owner fix a problem and earn a backlink at the same time.

How to do broken link building:

Find relevant websites in your niche with a high DA/DR
Use a Chrome extension such as Check My Links to find broken links on their pages
Check the Wayback Machine to see what used to be at that URL
Create or find a similar or better piece of content on your site
Email the website owner in a friendly tone: “I found a broken link on your page X, and we happen to have similar content that might work as a replacement”

5. Backlinks from Indonesian business directories

Listings in trusted business directories give you valuable backlinks and improve your local visibility. Focus on quality directories rather than volume:

Google Business Profile: Essential for local visibility in Google Search and Google Maps
Yellow Pages Indonesia (yellowpages.co.id)
Kompass Indonesia (id.kompass.com), a premium business directory
Clutch.co, for digital agencies and technology companies
Sortlist Indonesia, a platform that connects businesses with agencies
Ralali.com, for B2B businesses
Industry-specific directories for your niche

6. The Skyscraper Technique, updated

The Skyscraper Technique: find popular content in your niche that has attracted many backlinks, create a far more complete and up-to-date version, then contact every website that links to the old piece.

In 2026 the technique needs updating, because Google rewards the most useful content, which is not always the longest. Make your content better on depth (how much it explains), freshness (current data) and usability (a format that is easy to understand and act on).

7. Partnerships and business collaboration

Build mutually beneficial partnerships with complementary businesses that are not direct competitors. For example, if you run a web agency, partner with a graphic design studio, a digital advertising agency or a business consultant. Each of you links to the other's website from a “Partners” or “Recommended” page.

Backlink opportunities from partnerships:

Official partner pages
Testimonials and case studies published on client or partner websites
Sponsoring industry events and getting a link from the sponsors page
Joining industry associations (APJII, AMSI and others) that have member pages with links

8. Reclaim unlinked brand mentions

Plenty of websites mention your business or product name in their content without linking to you. Each unlinked mention is a missed backlink. Use Google Alerts or Ahrefs Content Explorer to monitor mentions of your business name, then contact the website owner and politely ask them to turn the mention into a live link.

What to avoid in link building

These risky link building practices can lead to a Google penalty and wreck your rankings:

Private Blog Networks (PBNs): Networks of fake websites built purely for links. Google is increasingly good at spotting them
Buying and selling links: Paid links without rel=”nofollow” or rel=”sponsored” breach the spam policies in Google Search Essentials
Blog comment spam: Comments that contain nothing but a link to your website
Excessive reciprocal linking: “You link to me, I link to you” on a large scale
Too much exact-match anchor text: Too many backlinks with exactly the same anchor text look unnatural

Metrics for measuring link building success

Track your link building progress with these metrics:

Domain Rating (DR) / Domain Authority (DA): An indicator of your website's overall authority. Measure it monthly
Number of referring domains: How many unique domains link to your website (more important than total backlinks)
Organic traffic: Is link building bringing more visitors from Google?
Target keyword rankings: Are your main keywords climbing as your backlinks grow?
Link velocity: How fast your backlinks grow. Unnaturally fast growth can trigger a penalty
