meta-description-too-long-or-too-short

Purpose

Search engine crawlers only show the first 150-160 characters of the description on the search results page, so if a description is too long, searchers may not see all of the text. If a description is too short, the search engines may add text found elsewhere on the page. Note that search engines may show a different description from the one you have authored if they feel it may be more relevant to a user’s search.
