What is dynamic rendering?
Is dynamic rendering allowed by Google?
At first sight, dynamic rendering could seem like a black hat technique, since the crawler and users do not see the same content. If this would be abused by web developers, it could lead to instances of trying to trick the web crawler. However, if the content on the two versions of the page is similar, the website does not run the risk of getting any penalties. So, not only is dynamic rendering allowed, but it is also recommended in some cases, as it helps Google better and faster understand the content it needs to crawl.
First of all, you should research whether you need dynamic rendering. If your URLs are being crawled correctly, there is no need to add it. If needed, we recommend using the services of an expert for implementing dynamic rendering. Learn more on the Google developer page.
