Backlink Profile Analysis

外链概况分析

This skill requires the DataForSEO extension:
bash
./extensions/dataforseo/install.sh
Check availability: Before using backlink tools, verify the DataForSEO MCP server is connected by checking if 
dataforseo_backlinks_summary
or similar tools are available. If unavailable, inform the user and provide install instructions.
本功能需要依赖DataForSEO扩展：
bash
./extensions/dataforseo/install.sh
可用性检查：使用外链工具前，请检查
dataforseo_backlinks_summary
或同类工具是否可用，确认DataForSEO MCP服务器已连接。如果不可用，请告知用户并提供安装指引。

Analysis Framework

分析框架

When analyzing a backlink profile, produce all 7 sections below.
分析外链概况时，请输出以下7个部分的内容。

1. Profile Overview

1. 概况总览

Use 
dataforseo_backlinks_summary
to get:
  • Total backlinks and referring domains
  • Domain rank / authority score
  • Follow vs nofollow ratio
  • Historical trend (growing, stable, or declining)
Scoring:
MetricGoodWarningCritical
Referring domains>10020-100<20
Follow ratio>60%40-60%<40%
Domain diversityNo single domain >5%1 domain >10%1 domain >25%
TrendGrowing or stableSlow declineRapid decline (>20%/quarter)
使用
dataforseo_backlinks_summary
获取以下数据：
  • 总外链数与引用域名数量
  • 域名排名/权威值评分
  • Follow与Nofollow链接占比
  • 历史趋势（增长、稳定或下降）
评分标准：
指标优秀警告危险
引用域名数量>10020-100<20
Follow链接占比>60%40-60%<40%
域名多样性无单个域名占比>5%1个域名占比>10%1个域名占比>25%
趋势增长或稳定缓慢下降快速下降（每季度下降>20%）

2. Anchor Text Distribution

2. 锚文本分布

Use 
dataforseo_backlinks_anchors
to analyze anchor text patterns.
Healthy distribution benchmarks:
Anchor TypeTarget RangeOver-Optimization Signal
Branded (company/domain name)30-50%<15%
URL/naked link15-25%N/A
Generic ("click here", "learn more")10-20%N/A
Exact match keyword3-10%>15%
Partial match keyword5-15%>25%
Long-tail / natural5-15%N/A
Flag if exact-match anchors exceed 15% -- this is a Google Penguin risk signal.
使用
dataforseo_backlinks_anchors
分析锚文本模式。
健康分布基准：
锚文本类型目标区间过度优化信号
品牌类（公司/域名）30-50%<15%
URL/裸链15-25%无
通用类（"点击这里"、"了解更多"）10-20%无
精确匹配关键词3-10%>15%
部分匹配关键词5-15%>25%
长尾/自然表述5-15%无
如果精确匹配锚文本占比超过15%请标记——这是谷歌企鹅算法的风险信号。

3. Referring Domain Quality

3. 引用域名质量

Use 
dataforseo_backlinks_referring_domains
to assess link quality.
Analyze:
  • TLD distribution: .edu, .gov, .org = high authority. Excessive .xyz, .info = low quality
  • Country distribution: Match target market. 80%+ from irrelevant countries = PBN signal
  • Language distribution: Should match site language. Foreign-language links can be spam
  • Domain rank distribution: Healthy profiles have links from all authority tiers
  • Follow/nofollow per domain: Sites that only nofollow = limited SEO value
使用
dataforseo_backlinks_referring_domains
评估链接质量。
分析维度：
  • 顶级域名分布：.edu、.gov、.org属于高权威域名，过多.xyz、.info属于低质量链接
  • 国家分布：需匹配目标市场，80%以上来自无关国家是PBN信号
  • 语言分布：需匹配站点语言，外语链接可能是垃圾链接
  • 域名排名分布：健康的外链分布应覆盖所有权威层级的域名
  • 单域名Follow/Nofollow占比：仅输出Nofollow链接的站点SEO价值有限

4. Toxic Link Detection

4. 有害链接检测

Identify potentially harmful backlinks using these patterns:
High-risk indicators (flag immediately):
  • Links from known PBN (Private Blog Network) domains
  • Unnatural anchor text patterns (100% exact match from a domain)
  • Links from penalized or deindexed domains
  • Mass directory submissions (50+ directory links)
  • Comment spam links (forum/blog comment backlinks at scale)
  • Link farms (sites with 10K+ outbound links per page)
  • Foreign-language links to English sites (unless intentional)
  • Paid link patterns (footer/sidebar links across all pages of a domain)
Medium-risk indicators (review manually):
  • Links from unrelated niches
  • Reciprocal link patterns (A links to B, B links to A)
  • Links from thin content pages (<100 words)
  • Excessive links from a single domain (>50 backlinks from 1 domain)
Output:
Toxic Link Report
=================
Total backlinks analyzed: X
Potentially toxic: Y (Z%)

High Risk (recommend disavow):
  [list with domain, reason, anchor text]

Medium Risk (review manually):
  [list with domain, reason, anchor text]
通过以下模式识别潜在有害外链：
高风险指标（立即标记）：
  • 来自已知PBN（私有博客网络）域名的链接
  • 不自然的锚文本模式（单个域名100%使用精确匹配锚文本）
  • 来自被处罚或被取消收录的域名的链接
  • 大量目录提交链接（50+个目录链接）
  • 评论垃圾链接（大规模论坛/博客评论外链）
  • 链接农场（单页出站链接超过1万的站点）
  • 指向英文站点的外语链接（非有意设置的情况）
  • 付费链接模式（跨域名所有页面的页脚/侧边栏链接）
中风险指标（人工审核）：
  • 来自不相关领域的链接
  • 友链模式（A链向B，B链向A）
  • 来自薄内容页面的链接（内容少于100字）
  • 单个域名导出过多链接（1个域名指向目标站超过50条外链）
输出格式：
Toxic Link Report
=================
Total backlinks analyzed: X
Potentially toxic: Y (Z%)

High Risk (recommend disavow):
  [list with domain, reason, anchor text]

Medium Risk (review manually):
  [list with domain, reason, anchor text]

5. Top Pages by Backlinks

5. 外链Top页面

Use 
dataforseo_backlinks_backlinks
with target type "page" to find:
  • Which pages attract the most backlinks
  • Pages with high-authority links (link magnets)
  • Pages with zero backlinks (internal linking opportunities)
  • 404 pages with backlinks (redirect opportunities to reclaim link equity)
使用target类型为"page"的
dataforseo_backlinks_backlinks
接口查询：
  • 哪些页面吸引的外链最多
  • 拥有高权威链接的页面（链接磁石）
  • 0外链页面（内部链接优化机会）
  • 带外链的404页面（重定向回收链接权重机会）

6. Competitor Gap Analysis

6. 竞品差距分析

For 
/seo backlinks gap <url1> <url2>
:
Use 
dataforseo_backlinks_referring_domains
for both domains and compare:
  • Domains linking to competitor but NOT to target = link building opportunities
  • Domains linking to both = validate existing relationships
  • Domains linking only to target = competitive advantage
Output:
Competitor Gap: example.com vs competitor.com
=============================================
Competitor has links from X domains you don't
You have links from Y domains competitor doesn't

Top 20 Link Building Opportunities:
  [domain, authority, anchor used for competitor, contact suggestion]
针对
/seo backlinks gap <url1> <url2>
命令：
调用两个域名的
dataforseo_backlinks_referring_domains
接口对比：
  • 仅链向竞品未链向目标站的域名=链接建设机会
  • 同时链向双方的域名=验证现有合作关系
  • 仅链向目标站的域名=竞争优势
输出格式：
Competitor Gap: example.com vs competitor.com
=============================================
Competitor has links from X domains you don't
You have links from Y domains competitor doesn't

Top 20 Link Building Opportunities:
  [domain, authority, anchor used for competitor, contact suggestion]

7. New and Lost Backlinks

7. 新增与丢失外链

Use 
dataforseo_backlinks_backlinks
with date filters to track:
  • New backlinks in last 30/60/90 days
  • Lost backlinks in last 30/60/90 days
  • Link velocity (new per month trend)
Red flags:
  • Sudden spike in new links (possible negative SEO attack)
  • Sudden loss of many links (site penalty or content removal)
  • Declining velocity over 3+ months (content not attracting links)
使用带日期过滤的
dataforseo_backlinks_backlinks
接口追踪：
  • 过去30/60/90天新增外链
  • 过去30/60/90天丢失外链
  • 链接增速（每月新增趋势）
危险信号：
  • 新增外链突然暴增（可能是负面SEO攻击）
  • 大量外链突然丢失（站点被处罚或内容被移除）
  • 连续3个月以上增速下降（内容无法吸引链接）
