Last time when I have written How to submit your sitemap to Google I have used HTML file method to verify my domain into Google webmaster tool. This is good news for webmasters who are comfortable with DNS record and now they can quickly verify their domain using Google webmaster tool.
In the recent update Google webmaster team added
we bring you another new way to verify. Verification by DNS record allows you to become a verified owner of an entire domain (and all of the sites within that domain) at once. It also provides an alternative way to verify for folks who struggle with the existing HTML file or meta tag methods.
This is somehow useful for users who wants to quickly verify their domain using DNS. Though depending on your domain registrar, your DNS propagation might take some time.
Do let us know which method do you use to verify your blog in Google webmaster tool?
