This tool helps you check what your website serves to user agents or bots when they visit a specific URL on your website.

If a SPA is relying on JavaScript, it may not serve all essential information for web bots or crawlers to read because sometimes some elements on the page are not loaded properly which can hinder GoogleBot from viewing the content of your page. To ensure better page ranking, it is essential to make sure all your content is presented appropriately and is viewable to crawlers.
