What is a Meta description?
As per the urban dictionary, the term meta means- about the thing itself. The meta description refers to the description of the link/blog/website/ database or any other search result. It is the black text present below the URL that describes what who can expect to read or see on clicking on the link.
Why are meta descriptions important?
Like any other description, a meta description makes people understand what your content is about and why they should bother reading about it in the very first place. If you have written a good description, it will give an impression to the reader that the article or content of your website is well organized and to the point. You will get more people to click on the link and this will increase your click-through rate and ranking on Google. You must have a meta description, we cannot compromise on it. It tells people you are real and have invested time in conveying the message of your page.
Ideal length of a meta description?

What this means is that the search engine changes the length of the meta tags frequently and will not display the extra words if it shortens the word limit. Therefore, keep looking at what Google expects and change the length of the meta description frequently. Do not make it verbose and difficult to understand.

Write a different meta description of each page-
If you write the same description for all your pages, they will appear to be the same. People looking for information will feel that the content is repetitive and there is not much data from your end. A unique meta information shows the efforts you put in to attract people.

Don’t cheat-
If your description does not match the content of your page. The bounce rate of your blog will increase. So write a description that is clear and in line with the content you want people to see.

Balance the key-phrase-
Include the key-phrase in your meta statement as it increases how many people click on the link and hence improves your page’s search ranking. Despite this, you should not crowd the description with keywords. Balance the content appropriately.
