Resources are the things you have to offer, and they are the reason you want to share your ‘content.’ The Resources you may offer are, for example, to do commissioned portrait paintings. Or you may provide portrait painting courses. Or you may have written a book about portrait painting which people can buy from you.
You don’t want to share your Resources over and over again.
You need to put resources in one specific place where people can find them through search engines.
You can direct your audience to your resources at the end of other content you share: this is the call to action at the end of the other things you share. You have to tell people what you want them to do next, or else they won’t do it.
You must make your Resources something that your audience will find helpful. There is no point in sharing other content if you do not have resources to refer them to at the end.
For a Resource, the title that works best is an accurate description of what an audience member will encounter when they peruse the Resource you provide. They will know if they want to check it out and will not feel cheated when the content does not meet their expectations. Getting them to open your Resources is nothing when you lose them forever after that. It also helps search engines understand who to show it to.
