Verify a Site www.theroofcleaners.com.au
Once you verify that you're the site owner, we can provide you with comprehensive statistics and error information about the pages in your site. If you're unable to verify, you can still use the webmaster tools, submit Sitemaps, and see detailed information about those Sitemaps as well as basic information about your site.
We offer two methods of verification. You can either upload an HTML file with a name we specify, or you can add a meta tag to your site's index file. Choose your preferred method below.
can someone please explain what all this means ? i would have no clue, i want to verify my site with google so i can use the webmaster tools, i think my site has been indexed as it comes up on 2nd page for the search roof cleaners, but the heading just reads INDEX.BVP which is obviously the name of my home page, how do i change this ? thanks if i choose to add a metatag option google gives me this code and says
Copy the meta tag listed below and paste it in your site's home page in the first <head> section of the page, before the first <body> section. Help 
<meta name="verify-v1" content="tm7VEVVL9yFMf+t+gYc05oQH2qX8PwUN+PVNbl+mF DU=" />
how do i do this ? thanks
