While not the most ideal way to drive traffic to your website since it requires a budget of money to spend in order to get that traffic, if you’re directing readers to the right page that converts well—whether that’s to an email sign up or purchase—then it can be a very lucrative investment scaling up your paid advertising spend when there’s a clear immediate financial return. Plus, the positive social signals you’ll be sending by having a lot of active visitors on your site, should help with getting more referrals and social shares—thus giving you more opportunity to drive traffic to your blog from other sources as well.
I completely agree that defintion of a target audience isa great first step, but would ask if adding in competitors to the analysis (mentioned here as a later step) helps draw out who your target audience would be via comparisons, i.e. showing who you are an who you are not - would be very interested to hear opinions on how this tactic can be used within the overall step in coordination with targeted keyword discovery.
How we use Canva: The optimized sizes and built-in templates make it fast and easy to create tall pictures for Pinterest, rectangular ones for Twitter, square for Facebook or Instagram, and any size in between. We find Pablo (another free alternative) to be great for Twitter-sized images of 1,024 pixels by 512 pixels, and Canva to work really well for all else.
