• very flexible integration
• you just need to copy and paste the single-line integration code that is provided to you in the Workbench
  See example: https://www.excentos.com/de/how-it-works-integration
• existing Quick Test possibility that allows you to run a test in your website if and how the Product Guide will integrate.
  See Quick Test documentation: https://www.excentos.com/en/documentation/site-integration#quicktest

there are no "real serious" disadvantages.

However, please be aware of the following:

• in some cases, there where conflicts of the website's CSS with excentos CSS (especially if the customer's website assigned styles to HTML identifiers instead of using class names)
  • solution: implement a workaround to rename excentos CSS classes or resolve other conflicts
• in very rare cases, there were conflicts of the website's JavaScript with excentos JavaScript.
  • solution: excentos will find the conflict and clarify how to solve it

There is not a significant advantage over using JavaScript. The only reason to use iFrame integration would be

• 100% safe against CSS and JavaScript collisions (but see comments on JavaScript integration above)
  • You are thus 100% sure that the look&feel corresponds to what you see in the Workbench preview (unless the iFrame does not use dynamic height)

• you or excentos will need to provide an iFrame that dynamically adapts to the size of the Product Guide, also in responsive behavior (e.g. different height for question cards than for recommendation list)
• the excentos Analytics do not detect the referrer / website that integrated the Product Guide, so it cannot analyze traffic generation within the excentos Analytics. Also for you as our customer, you will be able analyzing the traffic within the webpage that contains the iFrame, but not be able analyzing the traffic within the iFrame
