Tool Details

seo_meta_analyze

Fetches a URL and inspects all meta-related elements. Checks title length (optimal: 30-60 chars), meta description length (optimal: 120-160 chars), canonical URL, viewport tag, language attribute, Open Graph completeness, and Twitter Card setup. Returns a 0-100 score.

Input: { "url": "https://example.com" }

seo_heading_check

Parses all headings on a page and builds a visual hierarchy tree. Flags: missing H1, multiple H1s, skipped heading levels, empty headings, overly long headings (>70 chars), and duplicate headings.

Input: { "url": "https://example.com" }

seo_link_check

Extracts all anchor tags from a page, resolves relative URLs, deduplicates, and probes each link with a HEAD request (falling back to GET when needed). Classifies links as ok, broken, redirect, timeout, or error. Reports internal vs. external link ratio.

Input: { "url": "https://example.com", "max_links": 100 }

seo_keyword_density

Strips scripts, styles, and navigation, then tokenizes the remaining body text. Computes frequency and density for single words, bigrams, and trigrams (filtering stop words). When a target keyword is provided, checks whether it appears in the title, H1, meta description, and first paragraph.

Input: { "url": "https://example.com", "target_keyword": "seo tools" }

seo_page_speed

Measures Time to First Byte and total download time from the server's perspective. Counts external scripts, stylesheets, images, and iframes. Detects render-blocking scripts (missing async/defer), images without alt text or dimensions, missing compression, and absence of lazy loading.

Input: { "url": "https://example.com" }

seo_sitemap_parse

Accepts a sitemap URL or any page URL (automatically appends /sitemap.xml). Falls back to checking robots.txt for a Sitemap directive. Handles both <sitemapindex> and <urlset> formats. Validates URL count limits, lastmod freshness, duplicate entries, protocol consistency, and trailing slash patterns.
