Preview how your page appears in Google search results.
A SERP (Search Engine Results Page) preview shows how your webpage will appear in Google search results. It consists of three main elements: the title tag (blue link), the URL (green text), and the meta description (gray text). Optimizing these elements improves click-through rates and SEO performance.
Google typically displays up to 60 characters for the title and 160 characters for the description. Content beyond these limits may be truncated. This tool helps you preview and optimize your search result snippets before publishing.
Google typically displays the first 50-60 characters of a title tag. Keep your primary keywords within the first 50 characters and stay under 60 characters to avoid truncation.
No. Google may generate its own snippet if your meta description does not match the search query, or if the page content provides a better match. However, a well-written meta description improves click-through rates.
No. All processing happens in your browser. Your title, description, and URL never leave your device.
