Hello and thanks for contacting us. How you accomplish this depends on your website or CMS - HTML/CSS, WordPress, Drupal, etc. I recommend contacting our Live Support with verification for further assistance.
I removed the verification code as that's a potential security issue for you and I can't access your website.
Thank you for contacting us about a lost Google Site Verification file. Here is a link to Google's guide on how to verify your site ownership. After following that link, click the Verify your Property button, then select your Property. You will then see a download link in the HTML file section.
Thank you for your Google Verification question. I reviewed the TXT entry you setup, and it looks correct, although I can't compare it to what Google provided.
If you just created the record, keep in mind this type of DNS modification can take up to 24 hours to propagate, or push out to the world.
An alternate method for verifying your Webmaster tools account is to use the HTML verification file, which does not need to propagate.
If you have any further questions, feel free to post them below.
I lost the Google Site Verification HTML file, how I can generate again the Verification HTML file from WebMaster. Please Help me.
