If you are having trouble getting your site to verify with Google Webmaster there are a few reasons why this could be happening.
- Make sure that you have entered the proper code into the custom code field located under Website > Settings > Header code:
Note: Custom code editing is a premium feature and you may need to upgrade to access it.
Make sure you clicked Publish after you entered the code. This will apply the change to your site so Google can crawl it.
If you have done both of these things and are still not able to verify your site, you may have entered your URL incorrectly. Check your URL in Google Webmaster settings.
