How to Audit Your Site for Link Rot: A Complete Guide (Manual + Automated)

You know link rot is costing you money. You've seen the estimates — potentially thousands in lost commissions every year. Now comes the important question: how do you actually find and fix these broken links?

This guide covers everything from manual audits for small sites to automated solutions for larger operations. By the end, you'll have a clear plan for keeping your affiliate links healthy and your revenue flowing.

Manual Audits: The Hands-On Approach

If you run a smaller site (under 30-40 pages), manual auditing is tedious but manageable. Here's exactly how to do it:

Step 1: Inventory Your Affiliate Content

Start by creating a complete list of every page on your site that contains affiliate links.

Tools to help:

• Screaming Frog SEO Spider (free up to 500 URLs): Crawls your site and exports all pages
• Google Search Console: Shows indexed pages
• Simple spreadsheet: List every URL with affiliate links manually

Pro tip: Organize by content type — product reviews, roundups, comparison posts, resource pages. This helps prioritize later.

Step 2: Export All Affiliate Links

For each page, you need a list of every affiliate link. Here's how to get them:

Browser Method:

1. Visit each page
2. Right-click → Inspect Element
3. Use Ctrl+F (Cmd+F on Mac) to search for your affiliate network's domain (e.g., "amazon.com", "shareasale.com")
4. Copy each URL into your spreadsheet

Screaming Frog Method:

1. Crawl your site
2. Filter by "Outbound Links"
3. Export to CSV
4. Filter for affiliate domains

Step 3: Check Each Link (The Tedious Part)

Now comes the time-consuming part — verifying each link actually works:

1. Click every link and verify it loads correctly
2. Check the product is still available — not just that the page loads, but the product can actually be purchased
3. Note the status in your spreadsheet:
   • ✅ Working
   • ⚠️ Redirecting (still works but worth monitoring)
   • ❌ Broken/404
   • 🚫 Out of stock
   • 🔗 Needs update (affiliate ID missing, wrong product, etc.)

Time estimate: 2-3 minutes per link. For a 30-page site with 5 links per page, that's 7-8 hours of work.

Step 4: Prioritize Fixes

Not all broken links are equal. Fix them in this order:

1. High-traffic pages first — Check Google Analytics for your top 10 pages
2. High-intent content — Product reviews before general informational posts
3. High-commission products — Expensive items before cheap ones

Step 5: Update or Replace

For each broken link:

If the product is discontinued:

• Find the closest replacement
• Update the link
• Rewrite any product-specific content as needed

If the URL changed:

• Update to the correct URL
• Test the new link

If temporarily out of stock:

• Decide: wait it out or find an alternative?
• Add a note to your calendar to check again in 2 weeks

Step 6: Document and Schedule

Record what you fixed and when. Then schedule your next audit:

• 0-20 pages: Every 3 months
• 20-50 pages: Every 2 months
• 50+ pages: Consider automation (see below)

Free Tools for Link Auditing

If the manual approach sounds painful, these free tools can help:

1. Broken Link Check (brokenlinkcheck.com)

Best for: Quick scans of small sites

• Completely free
• Checks up to 3,000 pages
• Finds broken links but doesn't identify out-of-stock products
• No affiliate-specific features

Limitation: Only tells you if a page returns an error — won't catch products that are unavailable but the page still loads.

2. Screaming Frog SEO Spider

Best for: Comprehensive technical audits

• Free for up to 500 URLs
• Crawls your entire site
• Exports all outbound links
• Shows response codes (404, 301, 200, etc.)

Limitation: Still requires manual checking of each link to see if products are actually available.

3. Google Search Console

Best for: Identifying crawl errors

• Free with any Google account
• Shows 404 errors Google found on your site
• Limited to pages Google has crawled

Limitation: Only catches hard 404s, not soft failures like out-of-stock products.

4. Browser Extensions

Check My Links (Chrome): Quickly checks all links on a single page

Link Checker (Firefox): Similar functionality

Best for: Spot-checking individual pages

Paid Tools Worth Considering

As your site grows, free tools become insufficient. Here are paid options:

1. Ahrefs Site Audit

• Price: Starting at $99/month
• Best for: Comprehensive SEO audits including broken links
• Pros: Finds broken outbound links, tracks over time, integrates with full SEO toolkit
• Cons: Expensive if you only need link checking; no affiliate-specific features

2. SEMrush Site Audit

• Price: Starting at $119.95/month
• Best for: All-in-one SEO and marketing platform
• Pros: Detailed broken link reports, competitive analysis
• Cons: Overkill for just link monitoring; not affiliate-focused

3. Dead Link Checker

• Price: Starting at $9.95/month
• Best for: Affordable automated checking
• Pros: Cheaper than full SEO suites, automated recurring checks
• Cons: Basic functionality; doesn't check if products are actually available

The Problem with Generic Tools

Here's the challenge: most link checking tools — free or paid — have a critical blind spot for affiliate marketers.

They can tell you if a page returns a 404 error. They cannot tell you:

• If the product is out of stock
• If your affiliate tracking is working
• If the price changed dramatically
• If the product was replaced with a newer model
• If your affiliate link is still properly attributed

For affiliate marketers, a "200 OK" response means nothing if the product isn't actually buyable.

When to Use LinkRescue

Manual audits and generic tools work for small sites, but there comes a point where you need specialized help.

Consider LinkRescue when:

✅ You have more than 50 pages with affiliate links ✅ You manage multiple sites ✅ You publish new content regularly (weekly or more) ✅ You want to catch problems within 24 hours, not months ✅ You need to know if products are actually available, not just if pages load ✅ You're losing track of which links you've checked and when

What LinkRescue Does Differently

Unlike generic link checkers, LinkRescue is built specifically for affiliate marketers:

Affiliate-Specific Monitoring:

• Checks if products are actually available, not just if URLs work
• Verifies affiliate tracking parameters are present
• Monitors Amazon's frequently changing URL structures

Revenue Impact Analysis:

• Shows which broken links are on your highest-traffic pages
• Estimates potential lost commissions
• Helps you prioritize fixes by revenue impact

Automated Workflows:

• Daily scans of your entire site
• Instant Slack/email alerts when problems are found
• One-click fix suggestions

Designed for Scale:

• Handles thousands of pages
• Tracks link health over time
• Generates reports for stakeholders or clients

Making the Decision: Manual vs. Automated

Here's a simple framework:

| Site Size | Method | Time Investment | Cost | |-----------|--------|-----------------|------| | 1-20 pages | Manual audit | 4-6 hours/quarter | Free | | 20-50 pages | Manual + free tools | 8-10 hours/quarter | Free-$20/month | | 50-200 pages | Hybrid or LinkRescue | 2-4 hours/month + tool | $29-79/month | | 200+ pages | LinkRescue or enterprise | 1-2 hours/month | $79-299/month |

The break-even point: If your site generates more than $1,000/month in affiliate commissions, broken links are almost certainly costing you more than $29/month in lost revenue.

Your Action Plan

This week:

1. Do a quick manual check of your top 10 most-trafficked pages
2. Count how many affiliate links you have total
3. Note how many are broken or questionable

This month:

1. Decide on your audit frequency based on site size
2. Choose your method (manual, free tools, or LinkRescue)
3. Schedule your first full audit

Ongoing:

1. Monitor new content as you publish it
2. Review and fix broken links on your schedule
3. Track revenue recovery to measure impact

Final Thoughts

Link auditing isn't glamorous work, but it's some of the highest-ROI work you can do as an affiliate marketer. Every broken link you fix is money back in your pocket — often with just a few minutes of effort.

Whether you choose the manual route or an automated solution, the important thing is to start. Your future self (and your bank account) will thank you.
