Everything you need to know about XML sitemaps, technical limits, Chrome performance, and LinkExtractor capabilities.
LinkExtractor is a 100% free Manifest V3 Google Chrome extension that counts total links in XML sitemaps, analyzes sitemap indexes, validates hreflang alternate tags, tests CMS sitemap endpoints with Sitemap Hunter, and prepares structured data for LLM analysis.
Chrome renders raw XML documents using an internal XSLT/HTML tree generator. When rendering sitemaps with 10,000 to 50,000 URLs, hundreds of thousands of DOM nodes overload memory. LinkExtractor executes a background script directly via the chrome.scripting API to parse XML nodes without rendering delays.
Yes! LinkExtractor detects whether the active page is a standard <urlset> or a <sitemapindex>. For sitemap indexes, it displays the count of sub-sitemaps and lets you inspect child sitemaps in 1 click.
The Live HUD is a floating on-page badge injected automatically whenever an XML sitemap is loaded in your browser tab. It displays the real-time link count, sitemap type, and last modified date directly on the page so you never need to click an extension icon.
Sitemap Hunter scans the current domain against the 15 most common CMS patterns (e.g. /sitemap.xml, /sitemap_index.xml, /wp-sitemap.xml, /sitemap_products_1.xml) and queries /robots.txt to report active 200 OK sitemaps in seconds.
LinkExtractor extracts <xhtml:link rel='alternate' hreflang='...'> annotations, calculates totals, groups by language code, and alerts you to potential configuration errors like missing self-referential links.
Yes, you can export all extracted URLs, lastmod timestamps, priority levels, and image links into clean CSV, JSON, or plaintext formats with a single click.
The LLM Reader condenses verbose XML tags into a token-efficient markdown summary and generates ready-to-use prompts for AI models like ChatGPT, Claude, and Perplexity to analyze website architecture.
Yes, LinkExtractor is 100% free with no subscriptions, premium tiers, or hidden paywalls.
LinkExtractor requires only the minimum necessary Manifest V3 permissions: activeTab and scripting. It accesses the page DOM solely when you view an XML sitemap.
No. LinkExtractor operates completely locally within your browser. No URLs, sitemap contents, or browsing history are ever transmitted to any external server or stored in any remote database.
Yes. When Chrome opens and decompresses .xml.gz files in the browser, LinkExtractor parses the decoded document seamlessly.
Yes! LinkExtractor is compatible with all Chromium-based browsers, including Microsoft Edge, Brave, Opera, and Vivaldi.
Google enforces a hard limit of 50,000 URLs per individual sitemap file. LinkExtractor instantly checks if your current sitemap exceeds this limit and warns you if URLs are at risk of being ignored by Googlebot.
Yes. In the extension settings tab, you can toggle the floating HUD badge on or off according to your workflow preference.
