Wishing for seperate meta tags for each post in Blogger

Yes! I am now days I am searching for the techniques for entering separate meta  tags for each post in Blogger and I am amazed that there is a technique which gives way to have separate meta tags for each blogger post.

First of all lets discuss why do we need separate meta tags. If you are using Google's Webmaster tool you must be knowing the HTML suggestions link under Diagnostics tab. When I clicked the link I got some interesting result about my blog..Here I am attaching a screen shot...

The number 28 is the number of duplicate meta tags that the crawler has found on those pages. The pages  are blog post and the meta tags that are duplicated are I have entered from edit HTML option. Each post that is showing have these meta tags. Here the need of having the separate meta tags arises and something that Google has forget. I search on the whole Blogger forum and their articles I don't found any techniques. The Webmaster is showing suggestion and we don't have a valid option for this suggestion. So to find the solution on the suggestive problem by Google I asked Google( searched on Google) and I got the following technique.

You have to enter the above code for each post after the highlighted line and enter the URL of the post and the related keyword of the post. Means you have to enter each time the above mentioned code for every post you publish. If you have 100+ post then half of the source code will have been filled with the meta tags. Don't you think that unusual. The conclusion of the post is that I didn't enter the above mentioned code in the source code for this post and I am still searching for some valid technique...Do let me know if you have any....Happy posting. :-)
