There are various ways of verifying that the website you are registering belongs to you; the options are all presented to you when you try and register a site. For the blogs, what you need to do is choose the meta tag option. You need to go to your Google Blogger dashboard, choose the blog in question and edit the template. In the section, paste the meta code given to you in the registration process. Save the template.
Next you return to the Webmaster Tools verification and press the 'verify' button. This should verify your site straight away.
Another problem I had was with my www.steveturnbull.com site. It needed verifying but I was at work (in my lunch hour!!) and did not have access to my webserver or the html template for the site. I did, however, have access to my domain registrar's site (123-reg.com) which enabled me to use the DNS verification method. 123-reg wasn't listed in the drop down of possible registrars, so I had to do a little digging to suss out how to make it work.
All the other providers were instructed to leave the 'name' field blank, however 123-reg does'nt allow this. What you need to do is put the '@' symbol in the name field. Make the Type a TXT and then paste the string Webmaster Tools gives you into the content field which should leave you with something looking like this:
Again, press verify and this should work. With the DNS method, I guess there is the risk of it taking some time to propagate, but I didn't find this.
