1: Sign up or sign in
To use Webmaster Tools you’ll need to log in using your existing account
(or sign up for one). Start by visiting www.google.com/webmasters and clicking on the Sign In To Webmaster Tools
button. If you don’t already have an account, you’ll be able to create one at this point.
2: Site view
Once signed in, you’ll see a list of any websites you’ve previously added to Webmaster Tools. We’re going to add a new site to the service, so click the ‘Add a Site’ button on the righthand side of the page, but remember this view – you’ll want to return to it when you’re all set up!
3: Enter the domain
Adding a site is simple. Just enter its web address and Google will pick up all the details automatically. Note that if you have multiple domains pointing to the same site (for instance, yourdomain.com and yourdomain.co.uk), there’s no need to repeat this process for each one.
4: Verify your site
Google requires that you verify your ability to manage the website. There are several ways to do this, but the most common two are to either upload a specific HTML file that Google provides, or to add a meta tag to your site code. Complete verification and you’re all set up!
