### 問題與答案:
1. 為什麼連結健康對於 SEO 很重要?

原文外掛簡介
Link Diagnostics is a comprehensive link analysis tool that scans your WordPress site for link issues and provides detailed intelligence about your internal linking structure. If you’re serious about SEO and site maintenance, this plugin gives you the visibility you need to keep your links healthy.
For a detailed feature breakdown, screenshots, and technical overview, see the official
Link Diagnostic and Insights product page.
Why Link Health Matters for SEO
Over time, your site accumulates link problems. You delete old posts, change slugs, restructure content. Automated or manual redirect plugins create chains. External sites you have linked to in the past go offline. The result:
Redirect chains that waste crawl budget and slow page speed
Broken internal links that hurt user experience and rankings
Orphaned content that search engines can’t discover
Dead external links that signal poor maintenance
Inefficient internal linking that fails to pass authority to important pages
These issues directly impact your SEO health score in tools like Ahrefs, Semrush, and Screaming Frog. Link Diagnostics helps you fix them systematically.
Internal Link Health – The Big Win
This is where the plugin delivers maximum value. When you change a URL or delete a post, redirect plugins create a 301 redirect. Fine for visitors, but now you have anchor texts across your site linking to URLs that redirect elsewhere. Every redirect hop wastes crawl budget and dilutes link equity, seo tools detect it and tell you to fix, but then, your site is large, how many do you want to start fixing one after the other? well, that’s why this plugin exists.
What Link Diagnostics does:
Scans every post and finds anchor texts linking to redirected URLs. You see:
The post containing the link
The anchor text used
The current URL being linked to
Where that URL redirects to
The redirect type (301, 302, 307, 308)
Click “Fix” and the plugin updates the anchor’s href to point directly to the final destination. No more redirect chains. Your internal links point exactly where they should.
For a deeper explanation of how internal redirect chains affect crawl efficiency and SEO performance, refer to the
Link Diagnostic and Insights documentation.
Why this matters:
Preserves crawl budget by eliminating unnecessary redirects
Passes full link equity directly to target pages
Improves page speed (fewer redirect hops)
Boosts SEO health scores dramatically
Strengthens your internal linking structure
This one feature alone can move your site health score from 60% to 90%+ in SEO tools.
Other Internal Link Issues Detected
Beyond redirects, the plugin finds:
404 Errors: Broken internal links where the target page doesn’t exist
410 Gone: Links to permanently deleted content
500 Errors: Server errors on internal URLs
Redirect Chains: Multiple redirect hops before reaching destination
Each issue shows the source post, anchor text, problematic URL, and HTTP status code. Fix them directly from the admin panel.
External Link Error Detection
Your outbound links matter too. Link Diagnostics scans external links and reports:
404 and 410 errors (broken external links)
5xx server errors (unreliable external sites)
DNS failures and timeouts (unreachable domains)
Redirect chains on external URLs
You see which posts contain broken external links and can update or remove them to maintain content quality.
Link Intelligence – Understand Your Link Structure
This is the strategic part. Beyond finding problems, Link Diagnostics analyzes your entire link structure to reveal:
Most Linked Internal Pages
See which pages receive the most internal links. These are your content hubs and authority pages. You can:
Verify your most important pages are well-linked
Find pages that are over-linked or under-linked
Identify pillar content opportunities
Balance internal link distribution
Each page shows total inbound links and expandable details listing every source post with the exact anchor texts used.
Common Anchor Texts
Discover which anchor texts you use most frequently. This helps you:
Spot over-optimization (too many exact-match anchors)
Find opportunities for natural language variation
Maintain consistency across your content
Avoid anchor text patterns that look spammy
External Domains Analysis
See which external sites you link to most often. This reveals:
Your most frequently cited sources
Over-reliance on specific domains
Opportunities to diversify external links
External relationships worth maintaining
For each domain, see which posts link to it and what anchor texts are used.
Orphaned Pages
Find content with zero internal links. These pages are invisible to crawlers and users. Link Diagnostics lists every orphaned page so you can:
Add internal links from relevant content
Improve site-wide content discovery
Boost the authority of isolated pages
Ensure all content is accessible
URL Redirect Management
Built-in redirect manager handles site restructuring and migrations:
Create 301, 302, 307, and 308 redirects
Add multiple source URLs to one destination in bulk
Organize redirects with categories
Toggle redirects active/inactive without deletion
Bulk delete operations
Source URL uniqueness validation prevents conflicts
Perfect for handling old URLs after site migrations or content reorganization.
How Scanning Works
Click “Start Scan” on any tab. The plugin:
Queries your published content (posts, pages, custom post types)
Extracts all links from post content
Checks each URL via WordPress HTTP API
Stores results in custom database tables
Shows progress in real-time
Scans are on-demand only. No background processing, no automated changes. You control when to scan and what to fix.
