Google gives site owners the ability to customize the preview of their content in search results.
By default, Google always generates search fragments according to user requests and the types of devices they use.
It was just an allowed text fragment.
Google is now introducing several methods that allow you to fine-tune the content for preview.
These methods include the use of robot meta tags, as well as a new type of HTML attribute. Here is more information about each of these methods.

Customizing Search Fragments with Robot Meta Tags
The content displayed in the previews of the search fragments can now be customized using the meta tags of robots.
The following meta tags can be added to the HTML page or specified via the x-robots-tag HTTP header:
"Nosnippet" is an existing option that allows you to specify that you do not want the text fragment to be displayed on the page.
“Maximum fragment: [number]” (NEW) - Indicate the maximum length of the text in characters for your page.
“Max-video-preview: [number]” (NEW) - Say the maximum duration in seconds for animated video preview.
“Max-image-preview: [setting]” (NEW) - Specify the maximum size for viewing images on this page using “none”, “standard” or “large”.
The above robot meta tags can also be combined, for example:
<meta name = ”robots” content = ”max-snippet: 50, max-image-preview: large”>
New HTML data-nosnippet attribute
Google introduces a completely new way to limit.
The new data-nosnippet HTML attribute for span, div, and section elements may prevent certain parts of the HTML page from appearing in the text fragment in the search results.
You can use this method if you want Google to not use too much of your content.
Here is an example:
<p> <span data-nosnippet> Harry Houdini </ span> is undoubtedly the most famous magician who has ever lived. </ p>
The HTML attribute does not allow Google to provide a response (Harry Houdini) in the search results.
