About Blogger Post Snippets

Just like post thumbnails, Blogger / Blogspot also generates post snippets. Snippets are chunks of text from the first few lines of a blogger post. It can act as a summary or as the introductory lines of text to a post. A text snippet is 101 characters long and after that three dots (…) are added, marking the continuity of the post. If a jump break exists before those 101 first characters, then snippets are picked up to the jump break.
