What is a Technical SEO Site Audit?

The audit checks:

• Crawlability
• Indexing
• Website speed
• Mobile usability
• Site structure
• HTTPS security

Some of the most important crawlability checks are:

• Robots.txt file
• XML sitemap
• Broken internal links
• Redirect issues
• Crawl depth

Ensure that search engines can find content on critical pages.

Check for:

• Noindex tags
• Duplicate pages
• Thin content
• Blocked pages
• Orphan pages

Google Search Console can reveal the indexed or non-indexed pages.

Run a website speed and Core Web Vitals test

Every website’s speed is directly related to human experience and to SEO ranking. Faster Websites are more likely to have lower bounce rates and higher engagement.

Use:

• Google PageSpeed Insights
• GTmetrix

To analyze:

• Largest Contentful Paint (LCP)
• First Input Delay (FID)
• Cumulative Layout Shift (CLS)

In the course of the audit, inspect:

• Responsive design
• Mobile usability
• Font readability
• Button spacing
• Mobile loading speed

The poor mobile experience can have a tremendous impact on rankings.

Review HTTPS Security

Secure Web sites utilize HTTPS encryption. Google takes HTTPS into account as a ranking factor and users are more likely to trust a secure site.

Check for:

• SSL certificate issues
• Mixed content warnings
• HTTP pages pointing properly to HTTPS

Security issues can have a detrimental effect on both the SEO ranking and trust of the user.

The internal links assist search engines to understand how your site is structured and spread link juice to your pages.

During a technical SEO audit, a few key things to look for include:

• Broken internal links
• Orphan pages
• Excessive redirect chains
• Anchor text relevance

Proper internal links will enhance crawlability and topical authority.

• Sitemap is submitted in Google Search Console

A clean sitemap will help the crawlers become more efficient.
