Configuration > Spider > Rendering
This configuration allows you to set the rendering mode for the crawl:
- Text Only: The SEO Spider will crawl and extract from the raw HTML only. It ignores the AJAX Crawling Scheme, and client-side JavaScript.
- Old AJAX Crawling Scheme: The SEO Spider will obey Google’s long deprecated AJAX Crawling Scheme if discovered. If not present, it will crawl the raw HTML like default ‘Text Only’ mode.
- JavaScript: The SEO Spider will execute client-side JavaScript by rendering the page in its headless Chrome browser, crawling and extracting from the rendered HTML for content and links. Like Google, it will also discover any links in the raw HTML.
Please note: To emulate Googlebot as closely as possible our rendering engine uses the Chromium project. The following operating systems are supported:
- Windows 10
- Windows 11
- Windows Server 2016
- Windows Server 2022
- Ubuntu 14.04+ (64-bit only)
- macOS 11+
Please note: If you are running a supported OS and are still unable to use rendering, it could be you are running in compatibility mode.
To check this, go to your installation directory (C:\Program Files (x86)\Screaming Frog SEO Spider\), right click on ScreamingFrogSEOSpider.exe, select ‘Properties’, then the ‘Compatibility’ tab, and check you don’t have anything ticked under the ‘Compatibility Mode’ section.
