Hi all. We generally used following type of meta tags:

1. <title> ......................</title>
2. <meta name="description" content="......................... ">
3. <meta name="keywords" content=" ............................">

But I have seen many people used another meta tags along with above tags.

These are:

1. <META NAME="Title" CONTENT=".........................">
2. <META NAME="abstract" CONTENT=" ....................">
3. <META NAME="keyphrase" CONTENT=".......................... ">

I am little confused about this. Let me know what's these & why we used them.


Thanks & Regards
