Greenflare

What sets Greenflare apart from other free SEO tools is its advanced data extraction capabilities, which utilize XPath queries and CSS selectors. This allows users to scrape any custom on-page element they need for analysis, from structured data markup to specific schema implementations. The powerful filtering system lets you focus on specific URL patterns or site sections, making large-scale audits more manageable. Results export cleanly to CSV format for further analysis in spreadsheet applications or integration with custom reporting workflows. Being open-source means the SEO community can inspect the code, contribute improvements, and ensure transparency in crawling methodology.
