| Most websites produce content. Most of them never rank. The difference usually comes down to one thing: who links to them. Link building is the process of earning or acquiring hyperlinks from other websites back to yours. Without it, even great content stays invisible. This article shows you exactly how link building improves website authority and rankings, which types of links move the needle, and what you can do right now to build a strategy that works. |
1. What Is Link Building and Why Does It Matter for SEO?
Search engines treat links as votes. When Site A links to Site B, it signals to Google that Site B has content worth referencing. The more credible the site linking to you, the more weight that vote carries.
This idea goes back to Google’s original PageRank algorithm, which Larry Page and Sergey Brin built at Stanford. Two decades later, links remain one of Google’s top three ranking factors, alongside content and RankBrain.
So how does link building improve website authority and rankings? It does it by building your site’s credibility in the eyes of search engines, one trusted reference at a time.
| Quick Fact: A 2023 study by Ahrefs found that 96.55% of all pages on the web receive zero organic traffic from Google. The leading cause? No backlinks. |
The Two Sides of Link Building
Link building works on two levels:
• External authority: Other websites linking to you tell Google your content is credible
• Internal authority: Links within your own site help Google understand your structure and spread ranking power across pages
Both matter. Ignoring internal linking while chasing external backlinks leaves ranking potential on the table.
2. How Link Building Directly Improves Website Authority
Website authority is not an official Google metric. But concepts like Domain Authority (Moz) and Domain Rating (Ahrefs) have become useful proxies. Both are calculated primarily from the quantity and quality of backlinks pointing to your site.
Here is how each backlink you earn shifts your authority:
| Action | Effect on Authority | Timeline |
| Earn a link from a DR 70+ site | Significant domain rating increase | 2 to 6 weeks |
| Earn 10 links from DR 30-50 sites | Moderate, steady authority growth | 4 to 8 weeks |
| Lose a high-authority backlink | Authority can drop if not replaced | Immediate to 4 weeks |
| Build links to a specific page | Page-level authority and ranking boost | 2 to 4 weeks |
| Guest post on niche-relevant site | Topical authority + domain authority gain | 3 to 8 weeks |
Domain Authority vs Page Authority
Domain authority reflects the overall strength of your website. Page authority reflects the strength of a specific page. A link to your homepage builds domain authority. A link directly to a blog post or service page builds page authority for that URL.
When you want a specific page to rank for a specific keyword, build links directly to that page. Not just to your homepage.
3. How Link Building Improves Rankings: The Mechanics
Google uses links to do three things when evaluating your site:
1. Discover your pages faster through crawling
2. Assess how authoritative your site is compared to competitors
3. Understand what your pages are about through anchor text
Each of these directly affects where you show up in search results.
Anchor Text and Topical Relevance
Anchor text is the clickable text in a hyperlink. When someone links to your page using the anchor text “SEO services in Bangladesh,” Google reads that as a signal that your page is about SEO services in Bangladesh.
This is why anchor text strategy matters. A diverse, natural mix of branded, generic, and keyword-rich anchors signals authenticity. Over-optimised anchor text — where every link uses the exact same keyword — can trigger a Google penalty.
| Anchor text types you should use:• Branded: your company name (e.g. Kreatech)• Exact match: target keyword (use sparingly)• Partial match: variation of target keyword• Generic: “click here”, “read more”, “learn more”• Naked URL: the actual web address as the anchor |
Link Equity and How It Flows
Link equity (sometimes called “link juice”) is the ranking power that flows from one page to another through a hyperlink. Not all links pass equal equity.
Factors that affect how much equity a link passes:
• The linking page’s authority
• Whether the link is followed or nofollow
• How many other outbound links are on that page
• The relevance of the linking site to your topic
• The placement of the link on the page (in-content links pass more than footer links)
4. Types of Links That Actually Move Rankings
Not all backlinks help. Some hurt. Knowing the difference saves you time, money, and the risk of a Google penalty.
| Link Type | Value | Risk Level | Example |
| Editorial backlink | Very High | None | A journalist cites your research |
| Guest post link | High | Low (if relevant) | Article on industry blog |
| Business citation | Medium | None | Google Business, Yelp, Clutch |
| Forum/community link | Low to Medium | Low | Reddit thread, Quora answer |
| Paid link (undisclosed) | Negative | High | Paid placement, no disclosure |
| PBN link | Negative | Very High | Link from private blog network |
| Spammy directory | None | Medium | Low-quality link farm directory |
Editorial Links: The Gold Standard
An editorial link is one you earn naturally. A journalist writes about your industry, references your data, and links to your site without you asking. These carry the most weight because they are unprompted and from credible sources.
You earn editorial links by producing original research, publishing data-backed content, and building a reputation in your industry that journalists and bloggers want to reference.
Guest Posting Done Right
Guest posting means you write an article for another website, and they publish it with a link back to your site. When done on relevant, quality sites, it builds both authority and traffic.
The key word is relevant. A link from a cooking blog to a digital marketing agency does little for topical authority. A link from a marketing trade publication to the same agency is worth ten times more.
If you want to see how a results-driven agency approaches this, look at how Kreatech builds digital authority for clients through content and link strategy.
5. How to Start Building Links: A Practical Step-by-Step Process
Step 1: Audit Your Existing Backlink Profile
Before you build new links, understand what you already have. Use tools like Ahrefs, SEMrush, or Moz to see:
• Which pages already have backlinks
• Which links are toxic or spammy
• What anchor text is currently pointing to your site
• Who your top competitors get their links from
Disavow toxic links through Google Search Console. Chasing new links while dragging along harmful ones is counterproductive.
Step 2: Identify Link Targets
Find websites in your industry that link out regularly. Look for:
• Industry blogs that accept guest contributions
• Resource pages that list helpful tools or articles
• Journalists who cover your topic on Google News
• Competitors who lost backlinks recently (they may be open to replacement content)
Step 3: Create Link-Worthy Content
No strategy succeeds without something worth linking to. The content formats that earn the most backlinks:
| Top Link-Earning Content Formats:• Original data, surveys, or research studies• Comprehensive guides and ultimate resources• Free tools, calculators, or templates• Infographics backed by data• Expert roundups featuring industry voices• Case studies with measurable results |
Step 4: Outreach
Find the right contact. Write a short, personalised email. Explain why your content adds value to their audience. Make it easy to say yes.
What works in outreach:
• Address the person by name
• Reference something specific about their site or content
• Keep the pitch under 100 words
• Follow up once, five to seven days later
What does not work: mass email blasts, generic templates, or asking for a link without offering value.
Step 5: Track and Measure
Track every link you build. Monitor ranking changes for the pages you are building links to. If a page climbs from position 18 to position 6 after five new backlinks, that tells you the strategy is working.
6. Link Building Strategies That Work in 2025
6a. The Skyscraper Technique
Find a piece of content in your niche that has a lot of backlinks. Create something significantly better — more current, more detailed, more useful. Then reach out to everyone linking to the original and show them your improved version.
This works because you are not asking someone to link to you out of nowhere. You are offering an upgrade to something they already link to.
6b. Broken Link Building
Find links on other websites that point to pages that no longer exist (404 errors). Create content that fills that gap. Contact the site owner, tell them about the broken link, and suggest your page as a replacement.
Tools like Ahrefs Site Explorer and Check My Links (Chrome extension) make finding broken links fast.
6c. Digital PR and Data-Led Content
Create a study, survey, or dataset around a topic journalists in your industry care about. Pitch it as a story. When a publication covers it, you earn a high-authority editorial link without any traditional link-building outreach.
One well-placed link from a site like Forbes, HubSpot, or a major industry publication can do more for your authority than 50 average links.
6d. Local and Niche Directories
For businesses targeting specific regions, directory listings on respected local platforms matter. Google looks at citation consistency — your business name, address, and phone number appearing consistently across the web signals legitimacy.
For businesses in South Asia, understanding how SEO works at a local level is critical. See how SEO helps small businesses grow online in Bangladesh — the same principles apply to link building in any local market.
7. Link Building vs Other SEO Tactics: How Does It Compare?
Where does link building sit relative to other ranking factors? This comparison helps you prioritise your effort.
| SEO Tactic | Impact on Rankings | Time to Results | Difficulty | Longevity |
| Link building | Very High | 4 to 12 weeks | High | Long-term |
| On-page optimisation | High | 2 to 6 weeks | Low to Medium | Long-term |
| Technical SEO fixes | High (foundational) | 1 to 4 weeks | Medium | Long-term |
| Keyword research | High (enables rest) | Immediate planning | Low | Ongoing |
| Content creation alone | Medium | 4 to 16 weeks | Medium | Long-term |
| Social media signals | Low (indirect) | Immediate | Low | Short-term |
| Paid ads (PPC) | None (organic) | Immediate | Low to High | Stops when paid |
Keyword research underpins every link-building campaign. Before you build links to a page, make sure that page targets the right keywords. Learn more about why keyword research is important for SEO success before you plan your link targets.
8. Common Link Building Mistakes That Kill Rankings
Plenty of sites lose rankings — not from doing nothing, but from doing the wrong things. Here are the mistakes to avoid.
| Mistake 1: Buying links without disclosureGoogle’s guidelines require paid links to be disclosed with a rel=”sponsored” tag. Undisclosed paid links violate Webmaster Guidelines and can result in manual penalties. A manual action from Google removes your pages from search results entirely. |
| Mistake 2: Chasing quantity over quality100 links from low-authority, irrelevant sites will not outperform 10 links from respected industry publications. Google has been devaluing low-quality links since the Penguin algorithm update in 2012. That logic has only intensified. |
| Mistake 3: Ignoring link relevanceA backlink from a site in a completely unrelated industry passes little topical authority. Relevance is increasingly important. Focus your outreach on sites that already talk about topics connected to your niche. |
| Mistake 4: Building links to the wrong pagesIf you want your product page to rank for a commercial keyword, build links to the product page. Sending all your links to the homepage while your product pages have zero backlinks limits your ranking potential significantly. |
9. How to Measure Link Building Success
Link building without measurement is guesswork. These are the metrics that tell you whether your efforts are working.
| Metric | What It Tells You | Tool to Use |
| Domain Rating / Authority | Overall site link strength | Ahrefs / Moz |
| Number of referring domains | How many unique sites link to you | Ahrefs / SEMrush |
| Keyword rankings | Whether target pages are climbing | SEMrush / Google Search Console |
| Organic traffic growth | Ranking translating into visitors | Google Analytics 4 |
| Link velocity | Rate at which you earn new links | Ahrefs Alerts |
| Anchor text distribution | Natural vs over-optimised | Ahrefs / Majestic |
| Indexed backlinks | Links Google has actually crawled | Google Search Console |
Set a 90-day review cycle. Check your domain rating at the start and end of each quarter. Track ranking positions for every page you actively build links to. If a page moves from page 3 to page 1 in 90 days, replicate whatever you did.
10. Link Building for Different Business Types
E-Commerce Sites
E-commerce link building focuses on product and category pages. Target links from review sites, shopping comparison platforms, and journalists who write gift guides or product roundups. A single feature in a well-read gift guide can generate dozens of editorial links.
Service Businesses
Service businesses — agencies, consultants, law firms, clinics — should target local directories, industry associations, and media coverage. Local link building is especially powerful for service area businesses that depend on Google Maps and local pack rankings.
SaaS and Tech Companies
SaaS companies benefit from integration partnerships, tool directories (G2, Capterra, Product Hunt), and content-led link acquisition. Producing benchmark reports or free tools is a reliable way to earn links at scale in the tech space.
Agencies and Consultants
Agencies need to demonstrate authority, not just claim it. Case studies, industry contributions, and data-backed content all earn links from clients and peers. See how a 360 digital marketing agency in Bangladesh builds authority for clients across competitive markets.
11. Frequently Asked Questions About Link Building and Rankings
How long does link building take to improve rankings?
Most sites see measurable ranking movement within 4 to 12 weeks of consistent link building. The timeline depends on how competitive your keywords are, your current domain authority, and the quality of links you earn. For very competitive keywords (high volume, commercial intent), the timeline extends to 6 to 12 months.
How many backlinks do I need to rank on page one?
There is no fixed number. It depends on your competitors. Use Ahrefs or SEMrush to check how many referring domains the current top 10 results have for your target keyword. Match or beat that number with equal or better quality links, and you have a realistic path to page one.
Are nofollow links worth building?
Google’s official position is that nofollow links are “hints” rather than directives, meaning they may still pass some equity. Beyond direct equity, nofollow links from high-traffic sites drive referral visitors and build brand recognition. Include them in your strategy, but prioritise followed links.
Can I do link building without spending money?
Yes. The most cost-effective link building tactics — broken link building, guest posting, HARO (Help a Reporter Out) pitching, and creating shareable content — require time, not budget. Paid link acquisition speeds things up but carries risk if done outside Google’s guidelines.
Does social media help with link building?
Social media does not directly pass link equity (all social links are nofollow). But it amplifies your content to audiences who may link to it on their own sites. A well-shared piece of research can earn dozens of editorial backlinks from people who discovered it through LinkedIn or Twitter.

The Answer to How Link Building Improves Website Authority and Rankings
Links tell search engines which sites are worth trusting. The more trusted sites link to you, the more Google trusts your site. The more Google trusts your site, the higher your pages rank.
That is the core of it. Everything else — anchor text, link velocity, relevance, equity flow — is the detail that separates a site that ranks on page one from a site that never gets there.
Start with your audit. Build one genuinely useful piece of content. Reach out to ten sites this week. Do that consistently for 90 days. Track what moves. Repeat what works.
