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:

Metric	Good	Warning	Critical
Referring domains	>100	20-100	<20
Follow ratio	>60%	40-60%	<40%
Domain diversity	No single domain >5%	1 domain >10%	1 domain >25%
Trend	Growing or stable	Slow decline	Rapid 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	>100	20-100	<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 Type	Target Range	Over-Optimization Signal
Branded (company/domain name)	30-50%	<15%
URL/naked link	15-25%	N/A
Generic ("click here", "learn more")	10-20%	N/A
Exact match keyword	3-10%	>15%
Partial match keyword	5-15%	>25%
Long-tail / natural	5-15%	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）

Error Handling

错误处理

Error	Cause	Resolution
DataForSEO tools unavailable	Extension not installed	Run `./extensions/dataforseo/install.sh`
No backlink data returned	Domain too new or very small	Note: small sites may have <10 backlinks
API credits insufficient	DataForSEO balance low	Check balance at app.dataforseo.com

Graceful fallback: If DataForSEO is unavailable:

Inform user that backlink analysis requires the DataForSEO extension
Offer to check robots.txt and sitemap for basic link signals instead
Suggest manual tools: Ahrefs Webmaster Tools (free), Google Search Console Links report

错误	原因	解决方案
DataForSEO工具不可用	扩展未安装	运行 `./extensions/dataforseo/install.sh`
无外链数据返回	域名太新或站点规模过小	备注：小型站点可能外链数<10
API额度不足	DataForSEO余额不足	访问app.dataforseo.com查询余额

优雅降级方案： 如果DataForSEO不可用：

告知用户外链分析需要安装DataForSEO扩展
可提供robots.txt和站点地图检查服务，获取基础链接信号
推荐手动工具：Ahrefs站长工具（免费）、Google Search Console链接报告
