Even though Marketo hosts your landing pages, the URL can be totally customized. What it looks like without a CNAME:
The way it should look:
Pick a word to go at the beginning of the URL for your landing pages. It’s just one word and should be relatively short. Examples:
The one word (plus YourCompany.com) is called a CNAME. You’ll need this later so make a note of it.
Go to the Admin area.
Click My Account.
Admin Permissions Required
Scroll down to “Support Information” and copy your Munchkin ID.
Ask your IT staff to setup the following CNAME: (Replace the word [CNAME] and [Munchkin ID] with the text from the previous step.)
[CNAME].YourCompany.com > [Munchkin ID].mktoweb.com
Once your IT has created the CNAME, go to the Admin area.
Click Landing Pages.
Under the Settings section, click Edit.
Enter your CNAME in Domain name for Landing Pages, enter your Fallback page, enter your Homepage and click Save.
Your fallback page will be the page leads will get redirected to if your Marketo Landing Page is unavailable.
Nice job! Your landing pages are now branded with your company domain.
