Primary vs. Secondary target audience:
The Primary audience is the people who set out to find a website like yours. While the secondary audience are people who may be interested in what your website has to offer but they are not exactly who the website is targeted for. An example for a primary audience would be people looking to buy pr sell their homes would go to a realtor website. now for a secondary audience, if that same website had tips for keeping your home look beautiful, this would attract people who aren’t looking to sell at the moment but in the future they could become the primary target audience. The secondary audience is very important for future use of a website, they may not be using your service at the moment but they will remember your site for future use.
