A Google Webmaster Help thread has Google’s John Mueller recommending to one webmaster that it might be a good idea to verify your web site within Google Search Console more than just one way.

Most people use the file upload method, but if Google cannot access the file when they randomly check to see if they should verify the site – then the verification status can be lost. I should add, this is rare but does happen.

So John Mueller recommended to use two or more methods to verify your site with Google Search Console. Google offers several verification methods including:

HTML file upload
Domain name provider
HTML tag
Google Analytics tracking code
Google Tag Manager container snippet
Google Sites
Blogger

Not a bad idea, don’t you think?
