<\/span><\/h2>\nScreaming Frog SEO Spider provides an extensive array of metrics essential for understanding and optimizing a website’s SEO performance. Here are the most important metrics you can track and act on:<\/p>\n
<\/p>\n
1. Page Titles and Metadata:<\/strong><\/p>\n\n- Character length of page titles and meta descriptions (flagging too short, too long, or optimal)<\/li>\n
- Duplicate titles and meta descriptions across the site<\/li>\n
- Missing or empty meta descriptions and page titles<\/li>\n<\/ul>\n
<\/p>\n
2. HTTP Status Codes:<\/strong><\/p>\n\n- 200 (OK) \u2014 page loads successfully<\/li>\n
- 301 (Permanent Redirect)<\/li>\n
- 302 (Temporary Redirect)<\/li>\n
- 404 (Not Found) \u2014 broken pages<\/li>\n
- 500 (Server Error) \u2014 critical server-side failures<\/li>\n<\/ul>\n
<\/p>\n
These status codes help you identify broken pages, redirect issues, and server errors that directly impact crawlability and user experience.<\/p>\n
<\/p>\n
3. Page Depth:<\/strong> This metric shows how many clicks it takes to reach any page from the homepage. Pages buried too deep in the site architecture are harder for search engines to find, crawl, and index. Best practice is to keep important pages within 3 clicks of the homepage.<\/p>\n <\/p>\n
4. Word Count:<\/strong> Screaming Frog measures the word count of each crawled page, helping you identify thin content that needs expansion or consolidation.<\/p>\n <\/p>\n
5. Internal and External Links:<\/strong><\/p>\n\n- Number and source of internal links pointing to each page<\/li>\n
- Number of outbound external links per page<\/li>\n
- Nofollow and sponsored link attribute usage<\/li>\n
- Anchor text for all internal links (critical for topical relevance signals)<\/li>\n<\/ul>\n
<\/p>\n
6. Response Time:<\/strong> How long each page takes to respond to a server request. Slow response times negatively impact both user experience and Google’s ability to crawl your site efficiently.<\/p>\n <\/p>\n
7. Canonical Tags:<\/strong> Screaming Frog checks the presence and correctness of canonical tags across all pages, flagging self-referencing canonicals, canonicals pointing to other pages, and pages missing canonical tags entirely.<\/p>\n <\/p>\n
8. Hreflang Tags:<\/strong> For multilingual or multi-regional websites, Screaming Frog validates hreflang tag implementation \u2014 flagging missing return links, invalid language codes, and mismatched hreflang configurations that can cause international SEO issues.<\/p>\n <\/p>\n
9. Schema Markup and Structured Data:<\/strong> The tool detects all schema markup types present on each page (Article, Product, FAQ, BreadcrumbList, etc.) and validates them against Schema.org specifications and Google’s rich result requirements. Pages with valid structured data are eligible for rich snippets in search results.<\/p>\n <\/p>\n
10. Image Optimization:<\/strong><\/p>\n\n- Image file sizes (flagging oversized images that slow page speed)<\/li>\n
- Presence and quality of alt text<\/li>\n
- Image file names and src attribute values<\/li>\n<\/ul>\n
<\/p>\n
11. Core Web Vitals (CWV):<\/strong> Through integration with the CrUX API and Google’s PageSpeed Insights API, Screaming Frog can surface Core Web Vitals data (LCP, CLS, INP) at the URL level. This lets you identify exactly which pages are failing Google’s page experience signals and prioritize speed improvements accordingly.<\/p>\n <\/p>\n
12. Mobile Friendliness:<\/strong> When used in combination with Google’s Mobile-Friendly Test API, Screaming Frog can provide insight into a page’s mobile-friendliness at scale \u2014 particularly useful for large sites where manually testing every page is impractical.<\/p>\n <\/p>\n
13. Indexability Status:<\/strong> Screaming Frog flags every non-indexable URL and explains why \u2014 noindex directive, blocked by robots.txt, canonical pointing elsewhere, or a redirect chain. This helps you ensure the right pages are indexable and visible to search engines.<\/p>\n <\/p>\n
14. Crawl Depth and Crawl Path:<\/strong> The crawl depth report shows how far into your site structure each URL sits, while crawl path visualization maps the routes Googlebot would take through your site. These reports help identify structural inefficiencies and pages that need more internal links to surface properly.<\/p>\n <\/p>\n
Using these metrics together gives you a comprehensive, data-driven picture of your site’s SEO health \u2014 and a clear roadmap for improvement.<\/p>\n
