Google have announce another way to verify you own a domain in their webmaster tools, via a DNS TXT record.
This solves a problem I have had many times in that it verifies the whole domain.
Until now, you had to verify you owned every sub-domain on a domain before you could use webmaster tools for it, while for most sites this is fine, you verify the www. version, sometimes there are a couple more that need to be done.
for example on my site, I use the non-www domain, also there is a dev. and a api. that also need their own verification meta tag/html file. If I want to use webmaster tools on another sub-domain I have to verify again… this becomes a tiresome process.
Enter the new DNS verification. You now add a TXT record to your dns and it automatically covers any sub-domains you add.
That’s it… done! There is of course the usual dns propagation you have to worry about so it may not be a quick as adding a meta tag, but it defiantly saves time in the long run.
