Meta descriptions are important for SEO because they can help show up in search engine results when someone types in a phrase that is related to your blog. The length of a meta description is up to you, but it should be no less than 50 words and no more than 200 words.
A meta description should be relevant to the post it accompanies, but it shouldn’t be so long that it becomes difficult for people to read. A good rule of thumb is to keep the length of your meta descriptions around the same length as the post itself.
This way, people will see the most important information right away, and they won’t have to scroll down to find it.
A conclusion: Meta descriptions are an important part of SEO, so make sure they’re accurate, concise, and relevant to your content.
