If Google is displaying a different meta title or description than the one you provided, it's likely because they believe their version better serves the user's search intent. Google's priority is to help users find the most relevant content to answer their queries.

Why Does This Happen?

One of the main reasons Google may override your meta description is that it does not accurately represent the main content of your webpage. If Google's algorithm determines that a different snippet from your page is more relevant to a specific search query, it may replace your provided meta description with that snippet.
