How to Conduct a Technical SEO Audit in 2025

A technical SEO audit is essential for spray foam and insulation contractors who want their website to rank higher on search engines like Google. Without a well-optimized website, potential customers may never find their services online. This guide will walk contractors through the process of performing a technical SEO audit step by step.

What is a Technical SEO Audit?

A technical SEO audit is a comprehensive analysis of a website's technical aspects to ensure it meets search engine requirements for crawling, indexing, and ranking. It helps identify and fix issues that could prevent a website from appearing in search results.

By conducting a technical SEO audit, spray foam and insulation contractors can:

• Improve website visibility on Google

• Increase organic traffic

• Enhance user experience

• Boost lead generation and sales

Step-by-Step Guide to Conducting a Technical SEO Audit

1. Perform Website Crawling

Website crawling is the first step in a technical SEO audit. It involves using tools like Screaming Frog, Sitebulb, or Google Search Console to analyze the structure and health of a website.

Key areas to check during website crawling:

• Broken links: Identify and fix any 404 errors

• Duplicate content: Ensure there are no duplicate pages or meta descriptions

• Redirect issues: Verify that 301 and 302 redirects are correctly implemented

• Indexability: Confirm that important pages are not blocked by robots.txt or meta noindex tags

2. Check Website Indexation

After website crawling, it’s crucial to check how many pages are indexed by Google. This can be done using Google Search Console.

Steps to check indexation:

1. Go to Google Search Console

2. Click on “Coverage” under the Indexing section

3. Identify “Excluded” pages and resolve any indexing issues

4. Submit important pages using the “URL Inspection” tool

3. Optimize Site Speed and Performance

A slow website can drive visitors away and harm rankings. Google prioritizes fast-loading websites, making performance optimization a key part of a technical SEO audit.

Tools to analyze website speed:

• Google PageSpeed Insights

• GTmetrix

• Lighthouse (built into Chrome DevTools)

Ways to improve website speed:

• Compress images using tools like TinyPNG

• Enable browser caching

• Minimize HTTP requests

• Use a Content Delivery Network (CDN)

• Reduce unused JavaScript and CSS

4. Ensure Mobile-Friendliness

Google uses mobile-first indexing, meaning it primarily ranks websites based on their mobile version. A mobile-friendly website is crucial for insulation contractors targeting homeowners searching on their phones.

Steps to check mobile-friendliness:

1. Use Google’s Mobile-Friendly Test tool

2. Check responsiveness on different screen sizes

3. Optimize buttons and links for touchscreens

4. Improve font size and spacing for readability

5. Fix Structured Data and Schema Markup

Structured data helps Google understand website content better, which can enhance search result visibility through rich snippets.

Essential schema markup for spray foam and insulation contractors:

• LocalBusiness schema: Displays business information in search results

• FAQ schema: Increases visibility with frequently asked questions

• Service schema: Helps Google categorize the services offered

Use Google’s Rich Results Test to validate structured data implementation.

6. Improve XML Sitemap and Robots.txt

A properly structured XML sitemap helps search engines discover website pages efficiently. A well-configured robots.txt file prevents search engines from crawling unnecessary pages.

Best practices:

• Ensure the XML sitemap includes all important pages

• Submit the sitemap to Google Search Console

• Use robots.txt to block low-value pages (e.g., admin pages, duplicate content)

7. Optimize Core Web Vitals

Core Web Vitals are a set of Google metrics that measure user experience. They include:

• Largest Contentful Paint (LCP) – Measures loading speed

• First Input Delay (FID) – Measures interactivity

• Cumulative Layout Shift (CLS) – Measures visual stability

Improving these metrics can enhance site rankings and user experience.

8. Secure the Website with HTTPS

Website security is a ranking factor. Ensure the website has an SSL certificate (HTTPS) to protect user data.

Check for:

• SSL certificate validity

• Mixed content issues (HTTP elements on an HTTPS site)

• Proper redirection from HTTP to HTTPS

9. Conduct a Log File Analysis

Analyzing server log files provides insights into how search engines crawl the website. This can help detect crawl errors, slow-loading pages, and unnecessary bot activity.

Steps to perform log file analysis:

1. Download log files from the web hosting provider

2. Use tools like Screaming Frog Log File Analyzer

3. Identify crawl frequency, errors, and issues

10. Monitor and Fix Technical SEO Issues Regularly

SEO is an ongoing process. Regularly monitoring website crawling reports, Google Search Console insights, and performance metrics ensures the website remains optimized for search engines.
