Using Site Crawl

Site Crawl results will notify you of important site elements and issues that might impact your SEO:

On-page SEO: Meta tags, HTML headers and body content is checked for unoptimized or duplicate pages.
HTTP Status: Links and pages are checked for response codes that indicate missing or broken pages. Redirects are audited for broken links, loops and chains
Indexing: Pages that are unable to be crawled or indexed are listed here. This may be intentional, or possibly the result of errors in robots.txt or NoIndex tags.
Canonical: Canonical and Hreflang tags are audited to ensure they are pointed at functioning pages that are listed in the sitemap.
