Juzi SEO is a platform offering SEO lookup and analysis tools designed for webmasters. It integrates scattered, standalone tools into a unified, batch-capable system centered on three core areas: domain selection, backlink building, and content creation.
Its functionality focuses on three main categories. First is backlink analysis: it enables batch checks for backlink counts, anchor text, link distribution, and backlink history—supporting up to 20,000 domains per query—to help analyze a domain's SEO potential and evaluate the quality of reciprocal links. Second is website history analysis: it retrieves data on a domain's site-building history, historical titles, and page snapshots in batches (supporting 20,000 to 100,000 entries per query) to determine if an aged domain has been associated with spam, "gray-area" practices, or inappropriate content. Third is an unregistered domain marketplace: it filters through vast numbers of expired domains to identify those available for immediate registration that possess existing site-building history or backlinks. Users can filter by criteria such as long-term site history, historical authority, Chinese-language history, ".com" extensions, and the absence of sensitive keywords, with domains categorized by industry.
The platform also offers a comprehensive suite of tools for content and indexing analysis, including keyword optimization analysis, title/topic checks, on-page keyword detection, sensitive keyword scanning, online Chinese word segmentation, Baidu indexing checks, "Great Firewall" (blocking) detection, IP resolution checks, and reciprocal link quality analysis. Additional utilities include domain extraction and organization, batch URL opening, word counts, a comprehensive HTTP status code reference, and bandwidth calculators; API access is also available for programmatic integration.
