Many websites today have dynamic content generated by Javscript. Most search engine crawlers are only able to index html content since indexing JS pages are costly and difficult.

Not all search engines are able to crawl Javascript heavy pages. Expertrec is one of the few search engines that can do a JS crawl. If your website is heavy on Javscript. you can enable this option. If not, you can turn this off. The Javascript crawler takes snapshot of your pages and shows it if in case no image is present in a page, it shows the screenshot of the page as a thumbnail image in the search results.
