Getting Ready for the Audit
Let's set up your SEO toolkit to make your technical audit smooth and effective.
Enable Analytics Tracking
First, you'll need two key Google tools:
Google Analytics: Start by adding the GA4 tracking code to your site. Create a new property and check your real-time reports to make sure data flows correctly.
Google Tag Manager: This tool keeps all your tracking codes in one place - think of it as a command center for your website tracking.
Set Up SEO Tools
You'll need three main tools to power your audit:
Google Search Console is your go-to diagnostic tool. It shows you how Google sees your site. Set it up using either DNS or HTML verification.
Screaming Frog works like a detective, crawling through your site to spot technical issues. Download it and set it up to scan your URLs.
SEMrush brings powerful analysis features to the table. Its site audit tool can spot over 130 different technical problems.
Check for Penalties
Before diving in, check if Google has any issues with your site. Head to Google Search Console's "Security & Manual Actions" section to look for warnings or red flags that might be holding your site back.
Here's how to know your tools are ready to go:
| Tool | Setup Steps | How to Check |
|---|---|---|
| Google Search Console | Add site via DNS/HTML | Look at "Overview" page |
| Google Analytics | Add GA4 tracking | Watch real-time visitors |
| Google Tag Manager | Set up container | Test in preview mode |
Now that you've got your tools set up and checked for any penalties, you're all set to start your technical SEO audit.
Steps to Perform a Technical SEO Audit
Let's walk through the key steps of a technical SEO audit that'll help you spot and fix critical issues on your site.
Run a Website Crawl
Fire up WebSite Auditor or Screaming Frog to scan your entire site. Here's what you need to watch out for:
- Pages showing 404 and 500 errors
- Content that appears in multiple places
- Pages missing meta descriptions
- Links (both internal and external) that don't work
- Pages that users can't reach because no other pages link to them
Improve Page Load Speed
Here's an eye-opening stat: 53% of visitors will leave your site if it takes more than 3 seconds to load.
| Problem | Fix |
|---|---|
| Heavy images | Shrink and optimize them |
| Slow server | Get better hosting or add caching |
| Scripts loading too early | Move non-essential scripts to load later |
| Bulky CSS | Strip down and combine CSS files |
Check Mobile Usability
Since Google now looks at mobile versions first, your site needs to work perfectly on phones. Watch out for tiny text, wrong screen settings, and buttons that are too close together. Run your site through Google's Mobile-Friendly Test to make sure it passes.
Fix Broken Links and Redirects
Bad links and messy redirects frustrate visitors and hurt your SEO. Look for:
- Multiple redirects chained together
- 302 redirects that should be 301s
- External links that go nowhere
- Missing links in your site's navigation
Validate Structured Data
Structured data helps search engines better understand what's on your pages. This can boost your visibility and make your search listings look better. Check your markup with Google's Structured Data Testing Tool.
| Content | Schema | What You Get |
|---|---|---|
| Blog Posts | Article | Better-looking snippets |
| Store Items | Product | Shows price and stock in search |
| Customer Feedback | Review | Displays ratings |
| Physical Stores | LocalBusiness | Shows up in map results |
Adding the right structured data can help your site stand out in search results with eye-catching features that attract more clicks.

Advanced SEO Fixes
Let's look at some powerful techniques that'll boost your technical SEO. While these fixes need more technical know-how, they can make a big difference in how your site performs in search.
Manage Crawl Budget
Think of crawl budget as your site's daily allowance of search engine attention. For big websites, it's like having VIP passes - you need to make sure the right pages get through.
Here's what happens when you manage your crawl budget well:
- Your key pages get found and indexed faster
- Search engines spend less time on unimportant pages
- Your site's most valuable content stays fresh in search results
Look at Spotify - they cleaned up their site in 2023 by cutting duplicate URLs and blocking unnecessary pages from being crawled. The result? 40% more pages in Google's index.
Use Canonical Tags
Canonical tags are like traffic signs for search engines - they point to the main version of your content when there are multiple similar pages.
Here's what you need to know:
- Point all your product variations (sizes, colors) to the main product page
- Add self-referencing canonicals to your original content
- Double-check your canonical URLs use HTTPS (not HTTP)
Take Wayfair's example: In 2024, they cleaned up their product categories with canonical tags. By getting rid of 60,000 duplicate pages, they saw their organic traffic jump by 25% on main category pages.
Optimize Images and Resources
Want faster load times without making your site look bad? Here's what works:
| What to Optimize | How to Do It | What You Get |
|---|---|---|
| Product Images | Switch to WebP | 65% smaller files |
| Big Hero Images | Use lazy loading | 40% faster loading |
| Icons & Logos | Go with SVG | 80% less file size |
The Home Depot pulled off something impressive - they shrunk their product images by 70% using TinyPNG, and you can't even tell the difference in quality.
Conclusion
Looking at real data, most websites take 19 seconds to load on 3G mobile networks - that's WAY too slow. A technical SEO audit helps you spot and fix these speed bumps, making your site better for both search engines and users.
We've walked through 20 key steps that'll help your site perform better. But here's the thing: it's not a one-and-done deal. You need to keep checking and tweaking to stay on top.
Let's look at what a good technical SEO audit can do:
| Audit Area | Result |
|---|---|
| Site Speed | Cut load time to 3 seconds and keep 50% more visitors |
| Mobile Setup | Reach over 60% of web users across all devices |
| Structured Data | Boost click rates by 30% with better search listings |
Want to know what works? Top sites don't wait around - they check their technical SEO every 4-6 weeks, according to Ahrefs' 2024 research. Start with the basics: crawl your site monthly, check page speed weekly, and verify your structured data after big updates.
Think of it like maintaining a car - regular check-ups prevent bigger problems down the road. Your website needs the same kind of attention to run at its best.

(Quick note: "crawl budget" means how many pages Google will look at on your site during a specific time.)

Speed Matters: Get those load times down to 3 seconds or less.
Rich Results: Use Google's testing tools to check your schema markup - it helps your listings stand out in search results.
Keep an eye on your progress using Google Analytics or similar tools. Running these checks monthly helps catch issues before they become problems.
