Webgains

I just got approved on webgains and they sent me this message
Could you please perform one of the following actions:

1) Insert a meta tag to your site's homepage. i.e. "" .
or
2) Create a file named suuurrrl.html to the root folder of the domain of your website. (i.e. www.yourdomain.com/suuurrrl.html ).

I don't know how to do any of the steps, can anyone please guide me step by step how do either of them.
Tjank you
