What is the correct code snippet to prevent search engines from crawling a page in Webflow? And should the "noindex/nofollow" code be added to empty collection pages and the 404 page?

To prevent search engines from crawling a page in Webflow, you can add the "noindex/nofollow" meta tag to the page's HTML code. Here's the correct code snippet to achieve this:

```html

Now, regarding whether you should add the "noindex/nofollow" code to empty collection pages and the 404 page, here's a breakdown:

1. Empty Collection Pages: If your collection pages don't have any content or are placeholders, it usually makes sense to add the "noindex/nofollow" meta tag. This is because having empty pages indexed by search engines can be misleading for users and may negatively impact your website's SEO. By preventing their indexing, you ensure that search engines won't include them in search results.

2. The 404 Page: The 404 page is served when a visitor tries to access a non-existent page on your website. By default, Webflow includes the "noindex" meta tag in the code of the 404 page template, which tells search engines not to index it. This is the desirable behavior because the 404 page doesn't provide valuable content and its sole purpose is to inform users that they've reached a dead end. Therefore, there is usually no need to manually add the "noindex/nofollow" code to the 404 page.

Remember, the decision to add the "noindex/nofollow" meta tag to specific pages depends on their purpose and content. Generally, it's recommended to apply this code to pages that don't contribute or provide value to your website's SEO or user experience.
