Mobile-First Indexing
In one sentence
The mobile version of a page is the one indexed and ranked; the desktop version is secondary.
Analogy Mental model
The inspector judges only the takeaway, never the dining room. The packaging and the food decide the rating.
In practice What you actually do
Compare the two renderings element by element: text, images, links, structured data, metadata. The mobile page should be the complete page, not an abridged one designed for a smaller screen.
Where people get burned Pitfalls
Anything hidden on mobile with display none is not in the version being judged. Tidying a layout by hiding a paragraph now removes it from the index.
