Google uses a smartphone crawler and the mobile version of a site’s content for indexing and ranking. Its guidance calls for equivalent important content on mobile and desktop. A page that looks complete on a large screen therefore still needs a content check at mobile width. Source: Google Search Central: Mobile-first indexing

Compare the information, not just the layout

Open the same holiday page on mobile and desktop. Check the itinerary, inclusions, conditions and source links as well as the title and main copy. This helps identify useful information that has disappeared during a responsive layout change.

Check the route to enquiry

Test the navigation, enquiry form and contact links using a phone-sized view. Record any content that requires an unexpected action to reveal it. This keeps the review focused on what a visitor can understand and do, alongside the search engine’s access to the page.
