A Google SERP (Search Engine Results Page) simulator is a tool that simulates how a webpage might appear in Google search results. This online simulator is designed to help website owners, SEO professionals, and marketers preview how their page listings might look on Google when users search for relevant keywords.

This online simulator allows an user to enter a URL, and fetch the title and meta description used for the page. Also, the user may enter their own title and meta description, and inspect how Google will display the result on SERP. By doing so, users can optimize their meta tags to improve the click-through rate and overall appearance in search results.

Google may change how they display search results on SERP over time, so it would be a good idea to check the latest development for this purpose to ensure you have the most accurate and up-to-date information.
