Several tools are available to evaluate the SEO health of a website, including options provided directly by Google and those offered by third-party developers. These tools analyze various on-page and technical factors to provide insights into a website’s performance in search results. The Google SEO Checker, powered by the Lighthouse platform, assesses websites based on 14 key on-page SEO elements. Other tools offer additional analyses, such as rank tracking, content analysis, and backlink evaluation.
Google Lighthouse and the Google SEO Checker
The Google SEO Checker utilizes the Google Lighthouse platform to automate website audits. This platform was designed to improve the quality of web pages and provides feedback on areas such as performance, accessibility, best practices, SEO, and Progressive Web App (PWA) capabilities. The Google SEO Checker assigns a score from 0 to 100, categorizing website optimization levels as optimized (100-90), needing work (90-50), or not optimized (50-0).
The automated SEO analysis performed by Lighthouse reviews the following on-page SEO elements:
- Tap targets are sized appropriately
- Image elements have
altattributes - Structured data is valid (requires manual verification)
- Document avoids plugins
- Page isn’t blocked from indexing
- Document has a meta description
- Document has a
<title>element - Document has a valid
hreflangattribute - Page has a successful HTTP status code
- Links have descriptive text
- Document has a valid
rel=canonicaltag robots.txtis valid- Document uses legible font sizes
Google provides multiple resources to assist webmasters and website owners in improving their sites, including the Google Webmaster Blog, Search Console, the Google SEO Starter Guide, and Google Webmasters on YouTube. The Lighthouse platform represents a recent addition to these resources, focusing on on-page technical SEO.
Additional SEO Analysis Tools
Beyond the Google SEO Checker, several other tools can provide a more comprehensive SEO analysis. These include:
- Rank checker
- Website SEO checker
- Content analysis tools
- Domain and Page Authority score checkers
- Backlink analysis tools
- Competitor analysis tools
These tools complement the Google SEO Checker by offering insights into factors beyond the initial 14 on-page elements.
On-Page SEO Elements and Content Optimization
A comprehensive SEO audit includes evaluating content optimization elements. This involves analyzing titles and descriptions to ensure they are appropriate for Google previews. The structure of headings (H1-H6) should be reviewed for proper length and existence. Text length, the code-to-text ratio, and word relevance are also important considerations to avoid keyword stuffing and maintain clear, relevant content.
Structured data, specifically Open Graph markup, should be reviewed for accuracy. Correctly implemented structured data ensures content is displayed correctly and structured precisely on social media platforms, increasing clickability and shareability.
Image Optimization
Image optimization is a critical component of SEO. The Google SEO Checker verifies that image elements have alt attributes. Proper alt text provides context for search engines and improves accessibility.
Website Performance and PageSpeed Insights
Website loading speed significantly impacts user experience and search engine rankings. Google PageSpeed Insights analyzes a website’s loading speed on both desktop and mobile devices, evaluating factors like server response time, image optimization, JavaScript execution, and caching. The tool provides a performance score based on Google’s Core Web Vitals, which measure Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Recommendations are provided to improve page speed, such as minimizing JavaScript and CSS, enabling compression, and optimizing images.
