What’s more, the platform allows data from various SE Ranking tools to be combined into a single comprehensive report, such as website audit results with traffic data. 


  • Data Explanation: Although SE Ranking is praised for its ease of use and has a generous learning curve, some users believe that specific data could be better explained in terms of how it is generated or calculated.

SE Ranking offers three main subscription plans.

SEO Spider is designed to efficiently crawl large websites, gathering essential onsite data to enable informed SEO decisions. The tool integrates with Google Analytics, Search Console, PageSpeed Insights and other APIs. This makes it possible to provide a comprehensive analysis of user and performance data for all URLs during each crawl. It also offers unique site visualization features and the ability to schedule crawls at chosen intervals. With a visually appealing and intuitive interface, powerful crawling capabilities, and customizable settings, Screaming Frog’s SEO Spider is a valuable website audit software.

Screaming Frog interface

These reports can be seamlessly exported as CSV or Google Sheets files, ensuring easy access and sharing capabilities. This makes it convenient for quick resolutions or for passing the data onto a developer for further action. 
  • Different crawl modes: Screaming Frog is equipped with versatile scanning capabilities for various SEO tasks. For example, you can run a detailed analysis on one domain or check bulk URLs from multiple domains, generating numerous reports for each mode. 
  • Custom Settings: The tool lets you tailor its functionality to your specific needs, allowing you to include or exclude certain elements. This makes for a highly personalized auditing experience.
  • Google Analytics & Search Console Integration: Screaming Frog can integrate with the APIs of Google Analytics, Search Console, and PageSpeed Insights. This integration enables the tool to pull user and performance data for all crawled URLs, resulting in a more comprehensive analysis.
  • Precise Custom Search & Data Extraction: Screaming Frog allows you to perform custom searches and data extraction from a webpage’s HTML, offering a deeply personalized data-gathering experience. With this feature, you can extract almost anything, from page content to mentions of your brand.

  • Other Features: Screaming Frog offers a range of advanced audit features. For example, it can render web pages using the integrated Chromium WRS to crawl dynamic, JavaScript-rich websites and frameworks.


  • Comprehensive Crawling: Screaming Frog’s SEO Spider tool is known for its ability to crawl websites, much like how Google does it. It typically uncovers more website URLs than other audit tools. This ensures that it highlights potential issues that can stop search engines from discovering or attributing value to a site. As one user mentioned, it “lays out all the issues clearly and allows you to export them for further analysis.”
  • Detailed Analysis: The tool deeply analyzes technical and fundamental on-page issues. Users appreciate its precision and enjoy being able to export issues for further analysis. It’s perfect for technically inclined people and for techies who like to combine coding with SEO. 
  • Advanced Features: The tool boasts advanced search and extraction features, making it highly useful for site scraping and data extraction. It also offers excellent API access to tools frequently used by SEO professionals. 
  • Free Version: The free version of Screaming Frog is very functional and often sufficient for crawling small websites.


  • Outdated Interface: Some users have noted that the interface is dated and not as intuitive as they would like it to be. It may take an excess of time and effort to learn where to find different views and data.
  • Crawl Speed: The maximum crawl speed is limited to 20 URLs per second, which some users find too slow and wish to see increased.
  • No Health Score: The tool lacks a health score feature that would allow users to quickly estimate a site’s overall health or progress. This is a valuable metric that can be found in other auditing tools.
  • Lack of White Label Reporting: Users would appreciate a white label reporting option to present professional reports to clients, instead of having to create their own reports using crawl data.
  • Technical Complexity: The amount of information provided by Screaming Frog can be overwhelming for new users, especially at the beginning. Moreover, its high degree of technical complexity may demand tons of time and resources to fully understand and utilize all of its features.
  • Reconnecting Accounts: Users reported that the tool doesn’t save connected accounts, requiring users to reconnect their Google Analytics, Ahrefs, PageSpeed Insights, and Google Search Console accounts each time they open the app.


Screaming Frog’s SEO Spider tool comes in both free and paid versions. The free version let you crawl up to 500 URLs per website, making it great for small websites or for trying out the tool. However, it lacks advanced features like JavaScript rendering, custom extraction, Google Analytics integration, and more.

The paid version costs $259 per year for users requiring more extensive capabilities. It enables unlimited crawling and full access to the tool’s advanced features. Additionally, it allows users to save crawls and customize the tool to their specific needs.

Unlike most site audit tools, Screaming Frog does not offer a monthly payment option, which may or may not be a deciding factor for some users when considering a subscription.


Screaming Frog’s SEO Spider tool is a robust and flexible website crawler used by SEO professionals worldwide. It can efficiently crawl websites of all sizes and provides crucial onsite data for SEO strategies. Its API integration with Google Analytics, Search Console, and PageSpeed Insights provides a comprehensive user and performance data analysis. At the same time, its unique site visualization features and scheduling capabilities add to its appeal.

However, it has an older interface that can be challenging to navigate for newcomers, and its technical complexity may require a significant learning curve.

Due to its advanced nature, Screaming Frog is often used for in-depth audits that are not needed on a regular basis. While many SEO professionals rely on Screaming Frog for detailed or task-oriented checks, they might prefer a simpler solution like SE Ranking for regular, quick audits.

All that being said, the tool’s comprehensive crawling capabilities, detailed analysis, advanced features, and its functional free version would make it a valuable asset in your SEO toolbox.
