How to Activate and Use Meta Descriptions on Blogs
The description Meta tag on a webpage provides a summary search engine for a page. This Meta description can be either a sentence or a short paragraph that provides concise information about a particular page, while the title is a combination of several words or phrases.

What are the benefits of the Meta Tag Description?
The description Meta tag on a webpage is very important, the search engine might use the description as a snippet in the search results. This is still "possible" because search engines will look for more relevant parts to display as snippets in the search results. Alternatively, search engines might use data from ODP (Open Directory Project) as an alternative description of a webpage. Therefore, adding a meta description to each webpage is a good thing, if the search engine can't find the matching part to display as a snippet in the search results.

Tips for Optimizing the Use of the Meta Tag Description

Summarize Content Accurately

Write a description that provides information and can attract the user's attention if it appears as a snippet in the search results. You need to note that the description you make for each content page must be appropriate.

Avoid using descriptions that are not related to the content, otherwise don't use keywords that are repeated in the description because with the short number of words displayed in this search result it will be uninteresting. Copying the entire content and making it a description is also not a good thing and you need to avoid it.

Use Unique Descriptions For Each Content
Having a unique description for each content is the best thing to explain briefly about any content that is on the site. This will be very useful for users and search engines, because it can provide brief information about a page.

Avoid using the same description on all existing content, because it can confuse users and search engines, and this is something you don't need to do.

Use the description meta tag to provide an overview of what your content actually is to users and search engines.

Maybe that's all I can say about how to use the meta description on the blog homepage and description for blog articles or content, this needs to be re-learned to optimize search results on search engines, so that your website will have the best rank or position on each result content search.
