First of all, if you do not have a Google Account yet, you need to sign up for one. Go to SynthaSite's login page, login into your site and go to your index page.

1) Open up  Google Webmaster Central. in a NEW TAB in your browser. You should now be on the Google Webmaster dashboard. Enter your URL in the block provided.

2) Click on "verify your site" and select the "meta tag verification" option.

3) Here is an example of what you will see:
<meta name="verify-v1" content="lXgS3R9Xlzkq1Vgnox/0c9LeQ+W7+Utx8I=">

Copy only the long number you see between the quotation marks. In SynthaSite's site editor, click on the properties sidebar and paste that code in the specially designated "Google Webmaster" field. See picture below.
Do this for every page of your site that you want Google to track. Republish your site. Open the Google Webmaster tab and click on the verify button at the bottom.

4) Your site should verify immediately - see picture #4.
