In the second tab, include a snippet (make sure to create a new snippet and call it "shipping"), mainly because this will contain content that you do not want indexed by search engines, or to come up in a site search.
I tried to search with site:myshopify.com some content on the example site of the tutorial. I can find the site with content rendered from shopify pages but I find anything for content rendered from snippets.
Does that mean that HTML code rendered from snippets are not crawlable and indexed by Google ?
I hope not because I'm juste setting up my shop and I write a lot of dynamique content on snippets and put it into HTML code to keep my theme clean.
