Thanks for a great blog, subscribing to it as we speak (you just can't learn enough about SEO).

I couldn't get any of the methods I found on the web for redirecting to work, so I wrote a little widget that works if your self-hosted permalink structure is the same as your blogger structure. It requires a little personalization tweak because if you don't tweak it the homepage redirects to the the top post on your old blogger page. Place this code after your <Blogger> tag and switch the appropriate identification.
<b:widget id='Redirector' locked='true' title='Blog Posts' type='Blog'>
<b:includable id='main'>
<b:if cond='data:blog.pageType == "item"'>
<b:loop values='data:posts' var='post'>
<div id='redirectorTitle' style='visibility:hidden'><data:post.title/>
</div>
<script type='text/javascript'>

var url= '<$BlogItemPermalinkUrl$>';;
var myNewurl = url.replace("myblog.blogspot", "www.myblog");
var testurl ='http://www.myblog.com/2008/12/blog-has-moved.html';

if (myNewurl == testurl)
{document.location.href = "http://www.myblog.com";}
else{
document.location.href = myNewurl;}
</script>
</b:loop>
</b:if>
</b:includable>
</b:widget>

Notes:This assumes you are moving from myblog.blogspot.com to http://www.myblog.com
You must have structured your wordpress permalinks to match your blogger permalinks for this to work, which is easy enough to do in your wordpress dashboard.
The testurl variable will vary for you. The problem comes about because on your homepage the $BlogItemPermalinkUrl$ pulls the top post from the page rather than thinking you want the main page. Therefore, determine what the new version of that url will be and put it in here for your homepage to correctly route.

kindly guide me because I am going to buy my own domain within next 48 hours and am going to use as a blog
