Write Longer Meta Descriptions

Optimal length
Meta descriptions can be any length, but Google generally truncates snippets ~300 characters (this limit increased in December 2017). It's best to keep meta descriptions long enough that they're sufficiently descriptive, so we recommend descriptions between 50–300 characters. Keep in mind that the "optimal" length will vary depending on the situation, and your primary goal should be to provide value and drive clicks.

...neither meta descriptions nor meta keywords factor into Google's ranking algorithms for web search.
Meta descriptions can however impact a page's CTR (click-through-rate) on Google which can positively impact a page's ability to rank.
For that reason, among others, it's important to put some effort into meta descriptions.
