Call to Action can be extremely beneficial depending on how and where you put them to use and implement.
Nowadays most of websites are using IFRAME blocks to ensure marketing experts cannot add a call to action on their content.

So we come up with an innovative solution to solve this.
We create summary pages on the fly for the webpage you targeted to add a CTA.

This creates a summarized version of the webpage and de-clutters the webpage at the same time. Making it more appealing to the target audience.
Hence, we are breaking and hijaking the iframe and you can continue driving the traffic to your website based on others' content webpage.
