The importance of backlinks in modern SEO strategy

Backlink là “phiếu bầu” tín nhiệm từ các website khác

Backlink, hay còn gọi là liên kết ngược, được xem như một tín hiệu tin cậy mà các công cụ tìm kiếm – đặc biệt là Google – sử dụng để đánh giá độ uy tín của trang web. Một backlink chất lượng từ những trang có DA cao có thể thúc đẩy thứ hạng tìm kiếm đáng kể.

According to Ahrefs report (2023), 91% of websites without backlinks will never appear in the top 10 Google search results.

Key role in overall SEO strategy

Backlinks not only help improve search result positions but also:

• Increase referral traffic from linked sites
• Enhance domain trustworthiness and reputation
• Accelerate indexing speed of new content
• Support building personal/business brand

Real example: An SME in the cosmetics industry increased organic traffic by 68% within 4 months after collaborating on a backlink campaign from beauty blogs with DA > 40 (according to Google Analytics Q4/2022).

Checklist for building effective backlinks

• ✅ Analyze current backlink profile using Ahrefs/SEMrush
• ✅ Select quality link sources (avoid spam forums, low-reputation PBNs)
• ✅ Create content that can be cited (case studies, infographics, internal research)
• ✅ Reach out and build relationships with industry sites
• ✅ Regularly monitor DR/UR metrics and anchor texts

Warnings and challenges to note

Not all backlinks are good. Using low-quality backlink services can lead to Google penalties (Manual Action). Especially, backlinks from uncontrolled PBN systems or irrelevant content can have long-term negative effects.

Quick takeaway

A smart backlink building strategy that is selective and sustainable will be a solid foundation for long-term SEO. Instead of chasing quantity, focus on quality and relevance to create real value for the website.

Classification of quality backlinks and how to identify harmful backlinks

What is a quality backlink?

To increase website credibility, you need to choose the right type of backlinks. Below are some criteria to classify quality backlinks:

• Backlinks from domains with high DA/DR: For example, from sites like VnExpress, Wikipedia, or Forbes (DA > 70, according to Ahrefs 2023).
• Links in the same field: If you work in interior design, backlinks from architecture blogs are more valuable than from movie sites.
• Natural and user-shared: Backlink in the article content (in-context), instead of just placing it in the footer or sidebar.

How to identify harmful backlinks

Unhealthy backlinks can cause a website to be penalized by Google. Common signs:

• Backlinks from hacked, spammed, or low-trust sites (easily identified through tools like Ahrefs, Moz).
• Over-optimized anchor text kiểu “mua sofa giá rẻ”, “best casino 2024” lặp lại nhiều lần.
• backlinks from unrelated sites or from PBNs (spam network of fake sites).

Example: A customer in the cosmetics industry lost 40% traffic in 2 weeks due to having >200 backlinks from foreign forums selling drugs (source: DPS.MEDIA case study, 2023).

Checklist: check existing backlinks

• 👉 Use Ahrefs or Google Search Console to audit links
• 👉 Filter domains with DA
• 👉 Create a disavow list if harmful links are detected
• 👉 Prioritize building manual links through quality guest posts

Tuy nhiên, 6 link bị mất do đối tác xóa bài viết khiến lượng truy cập giảm hơn 10% – cho thấy tầm quan trọng của việc theo dõi thường xuyên.

Legal and ethical notes when using backlink services

Not violating Google's policies

Việc mua hoặc trao đổi backlink hàng loạt có thể bị xem là hành vi thao túng thứ hạng từ khóa – điều này vi phạm nguyên tắc của Google Search Essentials (2023). Nếu bị phát hiện, website có thể bị giảm thứ hạng hoặc bị loại khỏi chỉ mục.

• Avoid using PBN (Private Blog Network) with unclear origins
• Do not build backlinks from pages de-indexed by Google
• Prioritize backlinks from relevant content pages with transparent DA/DR scores

Comply with intellectual property laws

Some backlink services use copied or copyrighted content to speed SEO. If your site links to violating content, you may also face legal issues.

Ethics in link building strategy

Sustainable backlinks are not just about quantity. Building real relationships with related domains shows transparency in SEO strategy. Example: A travel company lost 401K traffic (Ahrefs, 2022) after Google Penguin penalized spammy blog links.

• Do not build links from pages with harmful, pornographic, or misleading content
• Always clearly disclose sponsored content when necessary
• Tránh “ẩn liên kết” bằng kỹ thuật CSS hoặc JavaScript

Checklist: implement backlinks legally and transparently

Practical conclusion

Việc sử dụng backlink hiệu quả đòi hỏi hơn cả kỹ thuật – đó là sự tuân thủ hệ thống luật và giá trị đạo đức. Một chiến lược minh bạch không giúp bạn lên top ngay lập tức, nhưng đảm bảo sự bền vững và tin cậy của thương hiệu về lâu dài.

How to choose reputable and transparent backlink service providers

Evaluate transparency in implementation methods

Một nhà cung cấp uy tín sẽ luôn công khai phương pháp xây dựng backlink, nguồn website và cách kiểm soát chất lượng. Tránh các đơn vị chỉ đề cập đến “số lượng liên kết” mà không có kế hoạch rõ ràng.

Below are signs of transparency:

• Commitment to provide a list of links (URLs) after each campaign
• allow domain check before linking
• Use audit tools like Ahrefs or SEMrush for reporting

First, providers with practical experience

Instead of just promoting SEO theory, choose units that have specific successful projects. For example, an agency that helped a financial niche website increase from 1,200 to 5,800 organic traffic/month (according to Google Analytics 2022) with backlinks from sites with DR > 50.

Quickly check reliability:

• Public or anonymous case study projects with evidence data
• Actual customer feedback (prioritize from competitive industries)
• Ability to replace broken, faulty, or deindexed backlinks

Checklist for selecting backlink placement partners

Common notes and warnings

Not many companies suggest backlinks from anonymous PBN (Private Blog Network), which can have high risks with Google's Penguin algorithm. According to Moz 2023 report, websites penalized for using PBN lost an average of 471 billion organic traffic after 60 days.

Brief Takeaway

Choose backlink partners with clear strategies, public data, and complete after-sales policies. A careful choice helps you avoid algorithm risks and achieve truly sustainable SEO results.

Negative balance still remains

Quality backlinks not only help improve rankings but also build trust with search tools. Proper investment will help SEO remain sustainable over time.
