Meta tags are an intrinsic part of SEO. They form or represent the technical side of the SEO. A beautiful thing about these tags is they are invisible to human visitors but visible for search engine spiders. And it won’t be wrong to say that they are written only to guide the search engines.
Meta tags are also called HTML tags as they are hidden inside HTML codes. Danny Sullivan rightly said that meta descriptions are the legal way of planting keywords on the page.
<head>Meta tags are located here</head>
Title: The title of the webpage is placed in the header. It is displayed in search results.
Description: It shows what the webpage is about. It is the summary that search engines read and use to determine a relevancy of the webpage with keywords. It should be short but comprehensive.
Keywords: The keywords used on the webpage are provided in this tag. Search engines know what keywords the page is targeting so that they rank the page for those keywords.
Importance of SEO
Meta descriptions have the key to success in SEO. Search engines read these tags and get crucial information regarding the websites. It is from the meta tags that the search engines determine the relevancy of the website keywords and its content.
SEO starts with writing meta descriptions for websites. A website introduces itself to search engines through its meta tags. SEOs should keep the tags clean and error free. Also, the tags should be descriptive but short.
