It’s essentially a “Google snippet preview” tool that lets you input your page title, URL, and meta description to see how your webpage will appear in search results seranking.com . Marketers and SEOs use these to optimize titles and meta descriptions for higher visibility and CTR before publishing.

By using a SERP simulator or preview tool. These tools (e.g. Mangools, Semrush, etc.) allow you to enter your title tag and meta description to generate a live preview of your Google result snippet. This shows exactly what searchers would see, including if your text gets truncated.

There’s no fixed number, because Google measures in pixels. Generally, titles around 50–60 characters (roughly under 600px) and meta descriptions ~155–160 characters (under ~920px) are displayed before truncation.

Not always. Google might rewrite your snippet text if it thinks it better matches the user query or your page content. In fact, “Google might change them but well optimized meta elements are more likely to show up in the SERPs”.
