| Keyword | Previous position | New position |
|---|---|---|
| Spa service District 3 | 34 | 10 |
| Laptop repair HCM | 19 | 5 |

How to identify quality and reputable PBN backlink services in the market
1. Check domain quality within the system
A reputable PBN system must own domains with strong metrics such as:
- DA (Domain Authority) From 20+ and above
- Using old domains with organic traffic still existing (according to Ahrefs/Semrush)
- Not penalized by Google (check via Google Search Console)
Example: An agency once used a domain with DA 35, TF 27 and natural traffic ~500/month from SEMrush, which improved top 10 rankings for 3 keywords within 2 months – but only after confirming the domain was free from spammy anchors or duplicate content.
2. Review content development model & hosting
A quality PBN service depends not only on the domain but also includes several key technical factors:
- Original content, no spinning – checked by Copyscape or Grammarly
- Hosting must have distributed IPs, not sharing the same server
- PBN site interface should be realistically designed like a blog or information site
3. Pre-use checklist
Before choosing to buy backlinks from any system, use the following checklist:
- ✔️ Request a full domain list report (anchor/text hidden is still acceptable)
- ✔️ Check IP and hosting ownership (using tools like IP Checker)
- ✔️ View real PBN post samples, not pre-made samples
- ✔️ Place a test backlink – monitor indexing and response within 15-20 days
| Criteria | SEO standards | Risks if missing |
|---|---|---|
| Independent IP | ✔️ | Google detects network |
| DA/PA >20 | ✔️ | Links without weight dilution |
| Unique content | ✔️ | Easily deindexed or sandboxed |
4. Be cautious with services priced under 50,000 VND/link
According to AuthorityHacker 2023 report, 78% of cheap PBNs use typical footprints, leading to an average 38% deindex rate within 6 months. With such low prices, you are likely buying dead, recycled, or flagged PBN links.

Choosing a PBN service must be based on thorough checks: don’t just look at price and ranking promises. A quality backlink is a long-term investment – not a shortcut for instant ranking boosts.
Guide to effectively build and deploy PBN suitable for SMEs
Define initial goals and budget
For SMEs, the first step is to clearly define SEO goals and financial capacity before investing in a PBN system. For example: if you want to push top 3 for main keywords within 6 months, you need to determine the required backlinks and budget to build corresponding satellite sites.
Quick checklist:
- Identify target keywords
- Classify keyword competition levels
- Prepare a minimum budget of 5-10 million VND/month for a small PBN
Choose domain names and build quality “niche” content
A common mistake SMEs make is buying weak domains or poorly convincing content. According to Ahrefs research (2023), 67% of PBNs do not bring long-term effectiveness due to lack of topical relevance.
TIP: Prefer to choose domains with DA from 15 or higher, clean backlinks, and in the same field. Avoid domains that have been penalized.
List of factors to check when buying a domain:
- Index history & old content (use Wayback Machine)
- Quality backlinks from reputable sources
- Not on blacklist or spam lists (check with Moz's Spam Score)
Manage hosting and safe footprint
Don't let Google detect your PBN system as "blowing up" the second tier. An SME in the cosmetics field in Ho Chi Minh City once lost 80% traffic in 2 weeks due to sharing IP for 8 PBN sites – data according to SEMrush, Q2/2022.
Principles for safe hosting deployment:
- Use different hosting IPs (can use Cloudflare to hide real IP)
- Do not use the same source code, theme, or plug-in for all sites
- Place links to the main site "softly" and naturally – avoid repeated exact match anchors
Suggested implementation levels suitable for SMEs
| Scale | Recommended number of domains to use | Estimated budget/month |
|---|---|---|
| Mini PBN | 3-5 domains | 5-8 million VND |
| Standard PBN | 6-10 domains | 10-15 million VND |
Monitor effectiveness and periodically adjust
Do not "neglect" PBN after placing links. Businesses should check effectiveness monthly and adjust anchor text, content, or number of links if results are unsatisfactory.
Action items:
- Use Google Search Console & Ahrefs to measure monthly metrics
- Remove or change backlink content if CTR is low or bounce rate is high
- Experiment with links by keyword clusters and content types (blog, infographic, etc.)
Risk warning when using uncontrolled PBN
Although PBNs bring quick results, the risk of Google penalties (manual action) always exists. SMEs should combine with long-term content strategy and natural backlinks.
Note: Avoid investing in PBN if you do not have a well-optimized main site. PBN cannot "rescue" a technically weak website with poor content.
Takeaway:
PBN is not a "shortcut" but a supporting tool with conditions. For SMEs, results come if you strictly control each domain, hosting, and content – always prioritize natural & safe factors first.
