WebCrawler Pro
WebCrawler Pro crawls websites and scores pages for technical SEO, answer-engine readiness (AEO) and generative engine optimization (GEO). Technical checks include titles, meta descriptions, H1s, canonicals, Open Graph tags, response times, page size, duplicate content, orphan pages and thin content. AEO checks include FAQ schema and question-based headings; GEO checks cover author attribution, freshness, factual density, authority links and original-research signals. Reports include crawl-depth charts, score distributions, response-time histograms, page breakdowns and site summaries, with PDF, CSV and JSON exports. Signed-in users can draft titles, FAQs, JSON-LD, alt text, internal links and llms.txt using a hosted model or their own API key. HTML mode fetches server responses; DOM Render executes JavaScript before extracting content. Guests receive 50 requests/day and signed-in users 100 requests/day. Paid tokens are listed at $1 a month. It supports Linux, macOS, Windows, web and self-hosting. Pages behind login walls, blocked by robots.txt or protected by advanced bot detection may not be fully crawlable.
