It is common to verify a blog using Google Webmaster Tools for several reasons.
Some of the benefits include access to realtime search statistics from Google, seeing what keywords are the most effective on your blog, and seeing insights into crawling and indexing activity on your blog.
That being said, Google Webmaster Tools is not a requirement for your blog to be successful and index well in the search engines.
If you have a custom domain name mapped to your blog, you can use the steps in this article to verify your blog with Google.
If you do NOT have a domain name mapped, verifying your Empower Network blog will not be possible.
Google's recommended method for verifying a site is to add a tracking tag to your website. At this time, HTML coding required to verify your site in Google is not supported. This is due to the possibility of infection on the Empower Network domain if bad code was submitted.
However, if you have a domain name mapped to your Kalatu blog, you can verify your side on Google by using an "Alternate Method". The Alternate Method you will choose will be to verify your site through your domain provider.
IMPORTANT - Again, this process will only work if you have a mapped domain to your Kalatu blog, but it is a workable solution to verify your site.
