Yes, you can definitely embed the salonMonster booking page into a page on your Website.
If you currently have a salonMonster account:
• Click on "Settings" in the left hand navigation
• Click on "Links / Buttons"
• Copy the "iFrame" code from the top box
• Paste the code into the html for your Website
• Save your page
When you visit your page you should now see your booking page embedded into your website.
Note: This will work for self-hosted Wordpress.org sites but not for Wordpress.com hosted sites as they block iFrames.
