– Tăng độ uy tín trang web trên công cụ tìm kiếm
– Gia tăng lưu lượng truy cập từ nguồn bên ngoài
– Cải thiện tốc độ index và đánh giá nội dung mới
Advantages and challenges for SMEs
Compared to large enterprises, SMEs often lack budget and personnel for intensive SEO campaigns. However, if used correctly, backlinks can still bring high efficiency without large investments.

Analyze check results to identify quality and bad backlinks
Criteria for identifying quality backlinks
To assess the quality of a link, focus on the following factors:
- Domain authority: Backlink from a site with DR/DA > 50 (as rated by Ahrefs/Moz, for example).
- Relevance: The content and topic of the referring page must be relevant to the website's field.
- Type of link: First dofollow backlink, appears in the main content (editorial backlink).
- Anchor text ratio: Limit anchor text that exactly matches the main keyword.
Signs to recognize bad backlinks
Bad backlinks not only reduce SEO value but also carry the risk of Google penalties. Some common characteristics:
- Links from spam sites: Sites with low-quality content, excessive advertising, or containing malware.
- Unusual anchor text: Excessive density of money keyword anchors.
- Links from unrelated sites: Example: A real estate website has a backlink from a weight loss blog.
- Links from PBN/public link farms: These sites have thousands of outbound links and no organic traffic.
Backlink classification checklist (Action items)
- ✓ Check the DR/DA and Organic Traffic of the referring domain (using ahrefs, ubersuggest)
- ✓ Evaluate the relevance from the topic and anchor text
- ✓ Gắn nhãn “Tốt” / “Nghi ngờ” / “Xấu” để lập danh sách xử lý
- ✓ Submit a Disavow file to Google if there are many toxic links
Summary table of common backlink types
| Type of backlink | Quality | Prioritize keeping? |
|---|---|---|
| Backlink từ báo chí (vnexpress.net, cafebiz.vn…) | Cao | Yes |
| Forum profile links | Low | No |
| Comment backlinks | Medium/low | Conditional |
| Blog content guest posts (related field) | Average to high | Yes |
| Backlinks from PBN or low-quality sites | Very low | Không – cần disavow |
Real-life example from an SME project
A client's (anonymous) interior design website has nearly 700 backlinks, but 37% of them come from unrelated sites with DA Warning: You should not remove all low-DA backlinks if they come from real forums or blogs. Google evaluates based on context, not just metrics.

A small business in Ho Chi Minh City once lost over 40% of its traffic due to 35 backlinks from foreign spam content sites. After using the Disavow Tool and optimizing internal links, the website recovered its ranking after 3 weeks (Source: Internal case study DPS.MEDIA, 2023).

Optimize backlink building strategy based on reports from free tools
phân tích điểm mạnh & lỗ hổng từ backlink hiện có
Using reports from tools like Google Search Console or Ahrefs Free Backlink Checker helps you understand:
– Tổng số backlink và referring domains
– Tỷ lệ backlink dofollow/nofollow
– Trang nào được liên kết nhiều nhất
– Anchor text đang được dùng phổ biến
An example from an anonymous DPS.MEDIA client: after analyzing with Ahrefs Free Tool, only 32% of backlinks were from sites with DR > 30. As a result, they prioritized building more links from high-quality local news sites.
Optimization actions: 5 specific steps
To take practical action based on the report, you can apply the following checklist:
- ① Identify links from low-quality sources (SPAM Score > 81%)
- ② Remove or disavow unnatural links
- ③ Prioritize building backlinks from sources with related topics
- ④ Increase the proportion of brand anchor text to diversify
- ⑤ Monitor monthly using the same tool to measure changes
Tip: Sử dụng Google Search Console để lọc theo trang được liên kết nhiều nhất. Thường có một vài bài blog “hot” thu hút phần lớn backlink – hãy tái sử dụng định dạng nội dung tương tự cho các bài viết khác.
So sánh hiệu quả trước & sau khi tối ưu backlink
| Indicators | Before Optimization | After Optimization (after 3 months) |
|---|---|---|
| Referring domains | 41 | 77 |
| Anchor text diversity | 12 types | 24 types |
| Organic traffic | ~580 visits/month | ~1,320 visits/month |
Source: DPS.MEDIA internal data, comparison report May-August 2023.
Warning: Avoid unnatural links
Although some free tools may not detect all toxic backlinks, Google can still identify them.
– Liên kết từ PBN (Private Blog Network) rẻ tiền tiềm ẩn nguy cơ penalize nội dung
– Đặt quá nhiều backlink với anchor thương mại dễ bị xem là thao túng
– Gửi Disavow List không chính xác có thể ảnh hưởng tiêu cực đến toàn site
Note: Hạn chế sử dụng cùng anchor text trỏ về nhiều URL khác nhau – dễ bị đánh cờ là unnatural pattern (theo Google Spam Policies, 2023).
Brief takeaway
Taking advantage of free tools to monitor backlinks is an important first step in building a sustainable SEO strategy. Act based on real data, don't chase backlink quantity at the expense of quality.
Effective backlink development orientation contributes to improving ranking and brand credibility
Understand quality over quantity
In modern SEO strategies, a few high-quality backlinks from trustworthy sources are more valuable than hundreds of irrelevant backlinks. According to Ahrefs (2023 Report), 91% of websites receive no traffic from Google due to a lack of or poor-quality backlinks.
- Prioritize websites with DA (Domain Authority) ≥ 50
- Choose sources related to your field of activity
- Avoid repeated link exchanges or public PBN networks
Chiến lược backlink dài hạn: Tập trung giá trị SEO & thương hiệu
Not just for SEO, quality backlinks also help increase brand credibility when appearing on news sites and industry forums. Example: A tech startup in Ho Chi Minh City increased referral traffic by 47% after 3 months of guest posting on 5 reputable industry blogs.
Effective backlink building checklist:
- Analyze competitor backlinks using Ahrefs or Ubersuggest
- Contact for guest post publication on related blogs/industries
- Create shareable content (infographics, guides)
- Monitor and remove toxic backlinks
Monthly tool and activity checklist
| Task | Support tools | Frequency |
|---|---|---|
| Backlink analysis | Ahrefs, OpenLinkProfiler | 2 times/month |
| Post guest posts | Email outreach | 1-2 posts/month |
| Remove toxic backlinks | Google Disavow Tool | Quarterly |
Risk notes and prevention methods
You should not buy cheap backlinks or use automatic backlink creation tools, as you may be penalized by Google (Google Spam Update 2022). Always check periodically to ensure your backlink profile is clean and not artificially manipulated.
Quick takeaway:
Tập trung xây dựng hệ thống backlink theo hướng bền vững – ít nhưng chất, liên quan và có ngữ cảnh rõ ràng – mang lại hiệu quả SEO lâu dài và góp phần nâng cao sự tin tưởng vào thương hiệu.
