The meta description is a snippet of text that describes the page content. If you include a meta description, it will be displayed in search results, especially if it includes the searched-for keyword. If you do not write descriptions, a snippet of text from your page that includes the keyword will be chosen by the search engine to include in search results. So, writing your own description puts the control in your hands. You can use it as an opportunity to entice people to click to your site.
- Write a sentence or two that describes exactly what a particular page is about while including important keywords.
- Keep the length to below 155 characters.
- Avoid repeating the title as the description appears directly below the title.
- Put the most important text first as it might be cut off on some displays.
