I heard that when changing host you should make sure that your host is based in your country, i.e. .co.uk domains should be hosted by a hosting company in the UK. I don't know if this is true but it makes sense I suppose.
I spent all night working out a tut for this blogger mess and then the computer froze. Damn Windows. Look, a bunch of people are being forced, or have been forced by blogger to switch over their old blogger blogs to new blogger blogs. And in doing so, they are carrying their old template over to the new console because they are not familiar with how the new blogger works or will work and frankly probably don't really care. Long story short - Everyone, or pretty much everyone, that is carrying over their old templates is unknowingly getting screwed with a nofollow-noindex tag. Thus the drop in blogger blogs from the index. First it just looks like a drop in traffic, and then the blog starts getting deindexed. Already happened here! And another catastrophe is the sites and blogs that those blogger blogs are linking to are feeling the hit too, because they are no longer get the link weight and anchor text from the blogger blogs that have been dropped. If you have links from a blogger blog(s) and your SERPs have dropped recently, this could possibly be the reason. If you have a blogger blog and carried over the old template into the new console, you need to remove the blog meta data tag which is causing the conflict with the new console and replace with a piece of your code in your current source code, not your template source. That's the only fix I have found so far until Blogger fixes this mess they have created. If the source code of your blog has this tag <meta name="ROBOTS" content="NOINDEX,NOFOLLOW" /> you are going to feel a hit from Google soon. Its not happening all at once because everyone doesn't post every day and Blogger gives you twice to log in before they make you switch over to new blogger. So if someone doesn't log in for another month, in theory, they won't have to change their blog over until next month or even longer or whenever, past that point. Make sense? The bit of code is easy enough to change: Looking at the code from one of the blogs in the OPs signature: If you just remove that nofollow-noindex tag , (BTW OP, this is from your blog so you need to do this too), and paste the rest of this into the TEMPLATE for your blog and get rid of the metadata tag in the template which creates this snippet of code, it should fix it so you don't get a nofollow-noindex from blogger. Now if someone see a simpler solution that I'm missing or sees something I'm screwing up, let me know, cause I don't want a bunch of bloggers down my throat. I'm just trying to help with what I see wrong. BTW - OP, I think this is what happened to your other blog too, but since you've changed to the website, I think you're okay.
