SEO Audit Checklist: Improve Website Performance and Google Rankings

by

SEO (Search Engine Optimization) helps websites rank higher on Google so people can easily find them. But having a website is not enough—it must be fast, well-structured, and optimized for search engines.

An SEO audit is like a health check-up for a website. It helps to:

  • Identify technical issues that prevent better rankings.
  • Fix problems that affect website speed and usability.
  • Improve content and keyword optimization to attract more visitors.
  • Ensure mobile-friendliness and security for a better user experience.

If a website is not optimized, it may lose traffic and potential customers without the owner realizing it. This step-by-step checklist will help identify and fix common SEO problems to improve search rankings.

1. Check If Google Can Crawl and Index Your Website

Google must crawl (scan) and index (store) your pages for them to appear in search results. If Google can’t access your content properly, your website will not rank.

How to check:

  • Use Google Search Console → “Coverage Report” to see indexed and excluded pages.
  • Check if any pages are blocked in the robots.txt file (which tells search engines which pages to crawl).
  • Look for “noindex” tags in your site’s code (these prevent pages from appearing in search results).

How to fix:

  • Remove “noindex” tags from important pages.
  • Submit an updated XML sitemap in Google Search Console.
  • Add internal links to connect all pages properly and help Google discover them.

2. Improve Website Speed and Loading Time

A slow website affects both user experience and search rankings. Google considers page speed a ranking factor because faster websites provide a better experience.

How to check:

  • Use Google PageSpeed Insights to analyze page load speed.
  • Check Google Lighthouse for detailed performance reports.
  • Use GTmetrix for speed and performance insights.

How to fix:

  • Compress images using tools like TinyPNG.
  • Enable browser caching to store common files for faster reloading.
  • Reduce unused JavaScript and CSS that slow down pages.
  • Use a Content Delivery Network (CDN) to distribute content globally and speed up load times.

3. Identify and Fix Broken Links and Errors

Broken links (404 errors) create bad user experiences and negatively impact SEO. Search engines may downgrade a site with too many broken links.

How to check:

  • Use Google Search Console → “Coverage Report” for error pages.
  • Run a crawl using Screaming Frog SEO Spider to detect broken links.
  • Check for redirect errors using Ahrefs or SEMrush.

How to fix:

  • Replace or remove broken links.
  • Use 301 redirects to guide visitors to the correct page.
  • Fix incorrectly configured redirect chains that slow down site navigation.

4. Analyze and Improve Content Quality

Content is a key ranking factor. If your content is outdated, low-quality, or lacks value, Google will rank your competitors higher.

How to check:

  • Use Google Analytics to find pages with high bounce rates.
  • Check Google Search Console for pages with low clicks and impressions.
  • Use Copyscape or Siteliner to find duplicate content.

How to fix:

  • Update outdated content with new information and statistics.
  • Ensure every page provides unique, helpful content tailored to the audience.
  • Use clear headings, structured paragraphs, and engaging visuals for better readability.
  • Optimize for featured snippets (answer-based searches) by structuring content clearly.

5. Ensure Mobile-Friendliness and Responsiveness

Over 60% of searches happen on mobile devices. Google uses mobile-first indexing, which means it ranks websites based on their mobile version.

How to check:

  • Use Google’s Mobile-Friendly Test.
  • Check how the website displays on different devices and screen sizes.
  • Test navigation, buttons, and form fields on a mobile device.

How to fix:

  • Use a responsive website design that adjusts to different screen sizes.
  • Ensure font sizes are readable and clickable elements are well-spaced.
  • Optimize images and videos to load quickly on mobile.

6. Improve User Experience (UX) and Navigation

Google prioritizes websites that offer a smooth and engaging user experience. Poor navigation leads to higher bounce rates and lower rankings.

How to check:

  • Use Google Analytics to track user session duration and page interactions.
  • Check how easy it is to navigate from one page to another.
  • Ensure your call-to-action (CTA) buttons are clearly visible.

How to fix:

  • Simplify website navigation with clear menus and categories.
  • Ensure key pages (About, Contact, Services) are easy to find.
  • Use internal linking to connect related pages and guide users smoothly.

7. Secure Your Website with HTTPS

Security is a major ranking factor. Google marks non-HTTPS websites as “Not Secure”, which can scare away visitors.

How to check:

  • Look at the website URL. If it starts with http:// instead of https://, it’s not secure.

How to fix:

  • Install an SSL certificate through your hosting provider.
  • Redirect all HTTP pages to HTTPS to maintain SEO rankings.

8. Optimize Google Business Profile (For Local SEO)

If you run a local business, a Google Business Profile helps you appear in Google Maps and local searches.

How to check:

  • Search for your business name on Google.
  • Check if the listing is complete with business hours, location, and photos.

How to fix:

  • Claim and verify your Google Business Profile.
  • Ensure business information is accurate and consistent across directories.
  • Encourage customers to leave reviews to improve local rankings.

9. Improve Internal Linking and Site Structure

Internal links help search engines understand how different pages connect and distribute authority across the website.

How to check:

  • Identify pages with no internal links using Google Search Console.
  • Check for orphan pages (pages not linked from anywhere on the site).

How to fix:

  • Add internal links to guide users to related content.
  • Use descriptive anchor text (avoid generic phrases like “click here”).

10. Optimize Meta Tags for Better Click-Through Rates (CTR)

Meta titles and descriptions affect how many users click on your search result. Poorly optimized tags can reduce traffic.

How to check:

  • Use Google Search Console to check pages with low CTR.
  • Ensure meta tags contain relevant keywords and are engaging.

How to fix:

  • Write compelling meta titles (under 60 characters).
  • Add clear, keyword-rich meta descriptions (under 160 characters).
  • Use proper H1, H2, and H3 headings for better structure.
