A website is the equivalent of having an office/shop on the internet. Just as every shop needs a sign board outside telling everyone the name of the shop and what you can get here a website too needs some sort of signboard. That signboard is really what you can call the header of your website and must contain what is called a “call to action”.
Some cool ideas for call to action are listed below. But really you are not limited by your imagination and can do something fancy specific to your website/business.
Phone Number
This is great for websites where you want the visitor to call you up for further details.
Email
If you want people to email you straight away then this might be a great idea (be aware that plain email is very likely to also attract spam)
Popup form
This is by far my favorite. A small phrase to get the interest of the visitor results in a click which opens a popup that shows a contact form. This allows the site owner to get a couple of fields from the user or maybe even have the visitor opt in to a mailing list.
Sticky button
This can be a button that sticks to the top or an edge of the browser and stays there even if you scroll through the website. The fact that it is always visible means that your visitor can take the action even if they are halfway through the page.
