It collects and analyzes thousands of metrics, providing valuable insights to improve the quality of your pages and content. This includes identifying and deleting duplicate content, ensuring proper page rendering, and addressing issues related to site size, access, and complexity.Log Analyzer

It also integrates with other data sources to give a holistic view of your website’s performance.SEO Impact Report
The SEO Impact Report generates actionable dashboards and reports that summarize the impact of various SEO factors on your website. This report helps in identifying the weakest technical factors on your site and prioritizing projects that can have the most significant impact on your SEO strategy. It contextualizes insights with data from other sources, such as Google Analytics 4 (GA4) or Google Search Console.Multi-Level Crawl Strategy
OnCrawl allows you to define the scope, frequency, and notification options for each type of analysis. This flexibility enables you to manage multiple projects and workflows, ensuring that you can crawl what you need, when you need it. This feature is particularly useful for simulating search engines, troubleshooting crawlability and indexability issues, and custom monitoring.API and Automation
OnCrawl’s API allows for extensive automation and customization. You can launch and program crawls, retrieve raw or analyzed data, and integrate this data into other tools and services like IFTTT or Zapier. This feature is useful for automating SEO audits, setting up customized alerts, and ensuring that your website is continuously monitored for any regressions or issues after updates.Integration with Data Science and Machine Learning
