I just have to express my frustration about the migration guide written by amit agarwal. A supposedly TOP blogger. Now I've followed his guide, which doesn't work as "advertised" at all. It's been two weeks and all the SERP's have been lost. They're still there for the old blogspot domain, although they're all dropping on a daily basis, since there is no description for any of the pages in the SERPs (that's how the redirection works). There is NO link juice being transferred, as NONE of my pages on my new domain are being ranked. Of course the author closed the comments on his post quite a while ago, and thereby deceiving more people into this practice and in turn serp loss. Make no mistake though, the redirection works just fine for your visitors. They're being redirected from blogspot to your new domain perfectly. However, there is no link juice being transfered as it seems and you will lose your serps. Although, admittedly two weeks is not a long enough timeframe to make definite conclusions, maybe the juice and serps will still move. However, his page says there's no serp or traffic loss, while in fact there is a MAJOR serp and traffic loss, at least for the time being. For me that time currently is 2 weeks. Translated, that means a few thousand dollars LOSS, so thank you Amit for your forewarning.
The link juice, rankings and other work benefits that you've done for the blog won't be transferred this fast to your new blog platform. Of course, it is a big risk that you've taken. People who migrate their blog from one platform to another either have the sustainable capacity or they don't have substantial traffic. I managed a wedding blog and had migrated everything from Blogger to WP when there used to be very less visits and it was not very popular. I lost my rankings and PR but again got it in 2 months time. I am sure you'll eventually get back to where you were. It is just a matter of time. But the losses can be huge.
I migrated before with a different technique with no loss at all, that's why I'm angry at this guy for giving misleading advice. The other migration was around 2 years ago though and blogger had some different options and functions, so the technique that worked back then doesn't work now. But since his post was so majestically ascended to the heavens from people who probably never tried it out, I trusted his opinion and went into this mess. I ranked #1 for a few keywords that are now in the abyss (but slowly moving up as I build links). Anyhow what's done is done, it would just be nice to hear the experience from someone who's done the exact same migration recently. If any of you is reading this, please do respond.
As of I know before start migration of blogger.com blog into WordPress. First thing always remember to change blog url from example.blogspot.com to your custom domain (example.com) where you actually wordpress want to install. Then wait for few days until google change all the links from example.blogspot.com to example.com. You can check that in google by searching site:example.blogspot.com and after few days (by adding custom domain url for your blog) site: example.com. Then only we should migrate post and pages from blogger.com to wordpress. This process will take long time (depends on the blog size) but it will not loss any page rank.
If you change your example.blogspot.com to your custom domain (example.com), there will always be a blogger page that will come up to the reader and asking him if he's really sure that he want's to follow the redirect. That will make some visitors click on the back button, plus I don't know just how exactly search engines react to that, but most likely all the juice goes away. However, making the switch might indeed help to delete the blogspot domain, keeping the custom domain only. And because I lost all my serps already, I can try this one out and I'll see where I get.
You migrated your blog from blogger.com to WordPress, so the above mentioned comment by me will not help you. But for the future perspective when you will migrate another blog you can take help from here bit[dot]ly[/]6jNJGg OR you can go with this processional service bloggertowp[dot]org[/]services[/] P.S.: replace [dot] with " . " and [/] with /
