Hi, I am confused to see many websites Meta keyword and description where at the end of meta tag close some website using backslash like <meta name="Description" content="abc. " />same as keyword closing line, but some websites dont use backslash . So, please, let me clear which is correct.
Closing a tag is necessary for your code to be correctly validated as per xhtml standards, so yes, you should do it, not that it has any known effects with search engines
back slash should be used as it is the correct way of XHTML...it doesnt make any effect for SEOs which is why people avoid.
