Make the most of the "description" Meta logo label
A description description tag for a Web page can give a summary of what is covered by Google and other search engine pages. The title of the page may be a few words or a phrase, but the description tag of the page may be a sentence or a short paragraph. Google Webmaster Tools provides a handy content analysis section (in fact, in Google Webmaster Tools-console-troubleshooting-content analytics), which can tell you which description tags are short or long , even too much repetition. (It can also display <title> label information). Like <title> tags, description tags are also placed in the <head> tags of your HTML documents.
The description tag of the homepage of our website gives the service or product content provided by the website.
The description meta tags are important because Google may use them as an overview of the content of your Web pages in search results. It is important to note that this is possible because if the content of the Web page is more likely to match the user's keyword query, Google may choose a portion of the content that is visible on your page. Similarly, if your site is listed in an Open directory (Open Directory Project), Google may also use your description meta tag here. (Learn how to prevent search engines from displaying ODP data). Adding description meta tags to each of your pages prevents Google from finding usable display fragments from your page content, and the Webmaster blog has an article about how to improve the selection of content fragments by description meta tags.
The content fragment appears under the title of the search results, on the original web site.

If a user queries a keyword in a content fragment, it will be highlighted in bold text. This gives the user a clue as to whether your Web page is the one he's looking for. Here's another example, this time extracting the content fragment of the search results from a description Meta tab of a deeper Web page that contains an article itself.
When a user queries [rarest baseball cards]
Our deeper page appears in search results, and its only description meta tag content is used as a result fragment.

Just fill in the description with the keyword.
Copy and paste all the contents of the document into the description meta tag.
Add a unique description for each page--different pages of different description content will help users and Google, especially in the results of your domain name under the multiple pages (for example: using site:operator< domain query, In the 101 Google search techniques are specified, translator > search. If your site has thousands or even tens of thousands of pages, manually adding description meta tags is not quite feasible. If this happens, you can try to automatically generate description meta tags based on the content of the Web page. But you have to avoid:
