Blurbs are those short pieces of linked text you put on a home page or an index page to drive traffic to content within your site. Because when you write your blurb before you start developing content - whether it be text, tools, apps or graphics you're actually vetting, editing, focusing and supporting that content all at once with a minimum of time and effort. And they therefore don't get clicked.
Bad blurbs are sometimes unavoidable.
Because bad blurbs often reflect the same lack of focus and organization within the content itself. The content is probably too complicated and should have been simplified. The content probably has no real benefit for the user built in to it and should never have been approved for development. That's probably because the content itself contains numerous, unrelated topics and should've been focused or broken down into several articles before it was published. By contrast, a good blurb is easily written because its matching content has a clear purpose, delivers a specific benefit and speaks to its intended audience in a voice that's appropriate.
