Once you have the Contactus.com Website Code copied, the next step is to paste it in your page’s HTML source code. (If you're not familiar with HTML, you’ll want to review our quick primer on HTML.)
Once you've copied your code, open the page you want to work on in your HTML editor. Set the cursor between the <BODY> and </BODY> tags, and paste the code.
You can do this from most “Edit” menus, or by right-clicking and using the display menu. Go to your HTML editor's “Preview” tab to confirm that the ad code is pasted correctly and page layout looks fine. Then, save the changes, add the changed file to your web server and publish the changes. Assuming everything is correct with the page and the code is unmodified, you should begin seeing the ContactUs Form and/or Button after about five minutes.
