Crawl budgets are limited, and Google wastes a lot of your budget trying to download, execute and render Angular code. This delay results in timeouts, which leads to the crawler leaving, and most of your URLs being undiscovered.
And for single-page applications (SPAs), it’s even worse because Google can’t interact with your site like humans do. So, when Google downloads your site files, bots see an empty page and won’t be able to find new links to crawl.
