Meta tags are added to a webpage to increase its visibility in the search engine. The Meta tags consist of three important components which are title, description and keyword. The title is the most commonly used Meta tag. It is displayed on top of the browser window. It acts as the title of the document. The Meta description is not shown on the browser but it is shown in the search result. The Meta description is often used in a webpage that does not contain text content. For example, in an art gallery site, the whole page displays only the picture. Since no text is placed on the site, you have to use the Meta description to optimize it with keywords. The Meta tags are usually added under the head tags. The Meta tags for each page should be unique. In this way, you can avoid duplication problem.
You should use a different Meta tags for each page in the website. The best keyword research tool for researching keyword is the Google AdWords keyword tool.

In order for the search engine to recognize a phrase as a single keyword, you have to use the comma. The most important keyword should be positioned in front followed by the less important keywords.
The title and description should be written properly so that people will be interested in viewing the web page. Sometimes, the search engine will display the Meta description in the search result if it couldn't find any keyword in the article. It is important to optimize the Meta title and description with keywords. By optimizing the Meta title and description, you will be able to rank well in the search engine. The keyword you use must have low competition. You should not use misspelled keywords in your Meta tag.

Using misspelled keyword also cause people to think that your site is unprofessional. When people see that your site is unprofessional, they will avoid it and won't consider buying your product. In addition, the keyword phrase you use must be meaningful. If the keyword phrase is not meaningful, the search engine will consider you as a spammer.
