What’s Included in This Checklist

This SEO audit checklist covers all key areas, including technical SEO, content optimisation, on-page SEO, keyword tracking, and backlink analysis.

Technical SEO Audit

A technical SEO audit ensures that search engines can crawl and index your website efficiently. Website accessibility should be checked to ensure that search engine crawlers can reach all important pages. Crawl errors should be fixed by using Google Search Console to identify and resolve issues. The robots.txt file should be correctly configured to allow or disallow appropriate pages. An XML sitemap should be submitted to ensure all pages are properly indexed. Internal and external broken links should be fixed to improve user experience and SEO.

Site Architecture and Navigation

A well-structured site improves both user experience and search rankings. Website structure should be logical and easy to navigate, helping users find information quickly. URLs should be clean, descriptive, and include target keywords. Breadcrumb navigation should be implemented to enhance user experience. Orphan pages should be avoided by ensuring all pages are linked within the site. Internal linking should be optimised to improve user engagement and SEO.

Page Speed and Performance

Fast-loading pages contribute to a better user experience and search rankings. Images should be optimised to reduce file sizes without losing quality. CSS, JavaScript, and HTML files should be minified to improve load times. Browser caching should be enabled to store static resources locally and reduce server requests. A Content Delivery Network (CDN) should be used to serve content faster. Lazy loading should be implemented for images and videos to improve performance.

Mobile Optimisation

With mobile-first indexing, ensuring your site is fully optimised for mobile devices is crucial. Responsiveness should be tested to confirm that the website adapts well to different screen sizes. Google’s Mobile-Friendly Test should be used to identify and fix mobile usability issues. Buttons and links should be appropriately sized for touchscreens.

Indexing and Coverage

Search engine indexing ensures that your pages appear in search results. All important pages should be indexed in search engines. Duplicate content issues should be resolved using canonical tags or redirects. Unnecessary pages should be excluded from indexing using the robots.txt file or noindex tags. The meta robots tag should be correctly configured to prevent search engines from indexing private pages.

HTTPS and Security

Security is essential for both search rankings and user trust. The entire website should be served over HTTPS for secure browsing. Mixed content issues should be resolved to prevent security warnings. Security headers, such as Content-Security-Policy, should be implemented to protect against cyber threats. The CMS and plugins should be regularly updated to prevent security vulnerabilities.

Content Optimisation

Content plays a key role in SEO success. Meta titles and descriptions should be unique, keyword-rich, and optimised for click-through rates. Primary keywords should be included naturally within the content. Header tags should be properly structured, using H1, H2, and H3 tags. Thin content pages should be improved by adding valuable and relevant information. Multimedia elements such as images and videos should be optimised with alt text and captions.

On-Page SEO Audit

On-page elements should be properly optimised for better search visibility. URLs should be clean and contain primary keywords while avoiding unnecessary characters. Internal links should be strategically placed to enhance navigation and SEO. Content formatting should be optimised for readability, with short paragraphs and bullet points. Calls-to-action should be clear and easy to find, guiding users toward conversions.

Keyword Research and Tracking

Keyword analysis is essential for targeting the right audience. Primary and secondary keywords should be identified for all key pages. Keywords should align with user search intent to improve relevance. Google Keyword Planner and Ahrefs should be used to research keyword opportunities. Long-tail keywords should be targeted for better ranking potential. Keywords should be grouped into clusters for content planning and topic authority.

Keyword tracking ensures that your rankings improve over time. Rankings should be monitored regularly using tools like SEMrush or Ahrefs. Performance benchmarks should be set for ranking improvements. Both local and global keyword performance should be tracked where applicable.

Structured Data and Schema Markup

Structured data enhances search visibility with rich results. Schema markup should be implemented for products, reviews, FAQs, and business details. Structured data should be validated using Google’s Rich Results Test. Sitewide schemas, such as organisation or website schema, should be added for better branding in search results.

Core Web Vitals and User Experience

Core Web Vitals are important for ranking and user satisfaction. The Largest Contentful Paint (LCP) should be under 2.5 seconds. The First Input Delay (FID) should be under 100 ms. The Cumulative Layout Shift (CLS) should be under 0.1 to ensure a stable page layout. Core Web Vitals should be regularly monitored using Google Search Console.

Analytics and Tracking

Tracking website performance allows you to make data-driven improvements. Google Analytics should be properly set up to track user behaviour and conversions. Google Search Console should be configured to monitor indexing and performance issues. Heatmap tools such as Hotjar should be used to analyse how users interact with the site.

Backlink Audit and Off-Page SEO

Backlinks contribute to domain authority and rankings. A backlink audit should be conducted to identify toxic or low-quality links. High-quality backlinks should be actively built through outreach and guest posting. Lost backlinks should be reclaimed by reaching out to site owners. Harmful backlinks should be disavowed to prevent negative SEO effects.

Additional Section: Future-Proofing Your SEO Strategy

SEO is continuously evolving, so future-proofing your website is essential. Voice search optimisation should be implemented by targeting conversational keywords and structured data. AI-driven SEO tools should be used to automate keyword research and content planning. Local SEO strategies should be improved for businesses targeting geographic areas. Regular SEO audits should be scheduled every three to six months to maintain performance.
