You have been rightly informed. You can check it in Google Cache, if the page is live, or using the Search Console.

Our CRO team is working on menu restructuring. What would yoy say should be kept in mind from an SEO perspective?

Our developer implemented a Read More button which when clicked opens the rest of the text on a category page. The content which is under the button is in the source code (View Source) , but it does not appear in the Inspect In Chrome before the button is clicked.

Is this an issue? I was told all content should be present in the initial load. That means it should be visible in Inspect Tool without clicking on the Read More button right?
