Mobile-first indexing
Google finished moving to indexing based on the phone version. If the phone view is missing text, a link, or a button that exists only on a wide screen, Google may not see them.
The same content, a different layout
A single column on a phone is fine. Missing content is not: a menu that hides links with no way to reach them, text that exists only on desktop, or a WhatsApp button that disappears.
A simple check: open the site on a phone and walk the same sections as on a computer. If the form cannot be reached, the site is not finished.
| Piece | On a phone | Mistake |
|---|---|---|
| Main text | The same content | A paragraph left only on desktop |
| Internal links | Reachable from the menu | A menu with no destination |
| Form | Can be filled and sent | Fields that are tiny or blocked |
| Phone and WhatsApp | Can be tapped | A number that is only an image |
