What triggers this issue?
This issue reports indexable pages where meta description tag is missing or its value is empty.
Why is it important?
A meta description tag is generally used to inform the search engine with a short, informative summary of what your page is about.
High-quality descriptions can sometimes be displayed in Google's search results as search snippets, helping you get higher click-through rates from SERPs.
In addition, if your page has no specific "og:description" or "twitter:description" tags, the text from the meta description tag will be used when your page is shared on Facebook or Twitter.
How to fix it?
Review the reported pages.
You should provide a unique description for each indexable page on your website to help search engines and people quickly understand what your page is about.
