Analysis of a 10-Day Black Hat SEO Optimization Case Reaching Weight 6

Backlinks are crucial—sufficient backlinks form the foundation for keyword rankings.
Keyword database matters—leveraging large volumes of low-competition long-tail keywords boosts weight.
Page templates are vital—rich content and functional elements deceive search engine algorithms.

1. Website Overview

Rankings began appearing on June 10, and after 12 days (by June 22), the site achieved Weight 6 on both PC and mobile (Aizhan metrics), with 30,000+ total keywords and estimated traffic of 43,335–67,997 IPs.

This site has a stable domain history with strong backlink resources:

• Orange SEO backlink score: 14,000

• Google PR: 4

• Domain age: 10 years (since 2011)

• Enterprise-registered site with ICP备案 (Chinese regulatory filing)

• Aizhan shows 20+ backlinks
  After being hacked, the site was injected with large volumes of film/TV-related keywords, and all content was scraped news articles.

2. Black Hat Tactics Analysis

① Interlinking
Multiple hacked sites interlinked their content pages (see screenshot below).

• Purpose: Helps all interconnected sites get indexed by search engines.

• Links point to internal pages for a “natural” appearance.

② Keyword Database Strategy
To gain weight, target keywords monitored by platforms like Aizhan, Chinaz, and 5118.

• High-traffic keywords are competitive; instead, focus on long-tail keywords with low difficulty that these tools track.

• Extract low-competition keywords from 5118’s database and use non-violative ones for optimization.

③ Scraped Content & Low Originality
All content is stitched together from scraped news/novels, with low readability and originality.

• Keywords appear in header, middle, and footer sections of pages but are not naturally integrated into content.

• Keyword density is intentionally kept low (1–2 mentions in TDK tags).

• Despite poor content, targeting low-difficulty keywords can still boost weight if the site has a solid foundation.

④ Page Layout & URL Structure
Although content is low-quality, black hat SEO carefully designs module placement and URL structures to trick algorithms:

• Mixed URL formats (e.g., /news/play/244995-1.html, /app/46822096, /tv/222927) make pages appear as different “sections.”

• Pages mimic legitimate video sites with modules like:

  • Film info

  • Episode selection

  • Synopsis

  • Cast list

  • Comments

  • “Recommended for You”

  • Popularity metrics

⑤ Key Observations from Deep Analysis
After studying 10 similar sites, findings include:

1. Backlinks are critical: Sites with more existing backlinks gain higher weight from these tactics.

2. Even low-authority sites benefit: Interlinking compensates for weak backlink profiles.

3. Domain age has minimal impact.

4. Some domains remain “unstoppable” (likely due to strong pre-existing metrics).

Additional Ranking Signals:

• Site info appears in site: searches (initial sign of indexing).

• Baidu site logo approval granted.

• Baidu index volume grows steadily (~40% same-day收录 rate).

• Continuous backlink growth.

3. Site “Nurturing” Strategy

• Prepare 30 websites using aged domains (3+ months of “nurturing”).

  • Why 30? To spread risk—if one gets penalized, others replace it.

  • Use DedeCMS (织梦) with static enterprise templates (homepage showing 30–40 article lists).

• Content rules during nurturing:

  • No illegal/gray topics—only plagiarized (easier to index, as search engines favor “hot” reposted content).

  • Update 10% of homepage list volume daily (e.g., 20 articles if homepage lists 60).

  • Rotate updates across categories.

  • Add basic友链 (friendship links) to encourage indexing (optional).

4. Deploying Black Hat

After 3 months:

1. Create a new folder in the root directory for black hat pages (HTML files).

2. Design keyword-relevant but industry-irrelevant lists (e.g., for keyword “X,” use titles like “Where is X located?”).

3. Content must be “original” (rewritten), with keywords bolded and hyperlinked.

4. Inject JS at the top to load third-party ads (avoids Baidu’s frame detection).

5. Post-Deployment Optimization

• Content: Keep updating until rankings stabilize.

• Backlinks: Purchase news portal backlinks (prioritize anchor-text links; available on Taobao).

6. “Stabilizing” Rankings

• Black hat rankings are inherently unstable. The real strategy:

  • Cycle through batches of sites (e.g., deploy Site 2 as Site 1 declines).

  • Avoid hosting all sites on one IP.

Notes on Translation:

1. Terminology:

   • “Weight 6” (权6) is retained as a metric from Aizhan/Chinaz.

   • “Black hat” is used directly (no equivalent neutral term).

   • “养站” translated as “nurturing” to convey the preparatory phase.

2. Technical Clarity:

   • Added brief explanations for tools like 5118/DedeCMS for non-Chinese readers.

   • Structured bullet points for readability.

3. Cultural Context:

   • Baidu-specific processes (e.g., logo approval) are kept intact.
