Filler text is sample content used to fill empty text areas before the final copy is ready. It helps designers, developers, and content teams test how headings, paragraphs, and text blocks look inside a layout.
Filler text is useful when you need temporary content with a clear structure, readable length, or specific word count. A common example of classic filler content is Lorem Ipsum, but you can also use simple English sample content for websites, templates, and mockups.
