The length of your meta description seems to be outside the recommended range. Ideally, a META DESCRIPTION should be between 50 and 160 characters, including spaces.

A meta description tag serves as a concise and informative summary of a web page's content, aiming to engage and inform users about the page's topic.

Google relies on the actual content of the page to generate a snippet for search results, but it may also utilize the meta description for a more descriptive representation of the page.

Meta descriptions act as a compelling pitch to persuade users that the page aligns with their search intent. While there's no strict character limit, Google truncates the snippet in search results as necessary to fit the device's width.

Best practices for Meta Descriptions

  • Length: Maintain a description length of 50-160 characters to ensure optimal visibility in search results.
  • Uniqueness: Craft unique descriptions for each page on your website to differentiate their purposes and content.
  • Accuracy: Create descriptions that precisely depict the specific content and purpose of the page.
  • Keywords: Ensure that each web page has a unique meta description containing important keywords relevant to the page's content.
