“The fact that our snippets have gotten longer doesn’t change the fundamentals of writing a description tag. They should generally inform and interest users with a short, relevant summary of what a particular page is about. We now display slightly longer snippets, which means we might display more of a meta description tag. However, we never had a limit on meta description tag length before, as we covered earlier this year. So, there’s no need for publishers to suddenly expand their meta description tags, if they feel their current ones are adequate. As a reminder, our snippets are dynamically generated. Sometimes, they use what’s in a meta description tag. More often, they are generated by showing content from the page itself and perhaps parts of the meta description tag, as is appropriate for individual queries. “
