As a marketer, CTAs are relevant because they encourage your audience to take action on a marketing campaign.
Below are a few examples of the types of CTAs you might use in marketing materials:
Try for free. Nearly every company website has a free trial offer today. Each of them are CTAs of this variety, and they allow people to demo a product before deciding if it's worth the cost to them.
Learn more. Sometimes, all you want is to give your potential customers a little more information so they're prepared to buy something. That's what this CTA is for.
Join us. Do you manage an online community? Is your product built on collaboration between users? You might find yourself placing "join us" CTA somewhere on your website.
What are your favorite phrases to use when pointing to different products or content offers?
I think image CTA is the best way to get the attention. since i am a student of SEO i find bunch of interesting CTA's, for e.g. Convert Traffic into Revenue -> Sign up for free SEo Audit
