There are a host of metrics to look at when you have a robust analytics solution, but having too many goals to live up to tends to result in prioritization difficulties. I recommend content marketing teams have 2-3 metrics they measure, and perhaps some secondary metrics each sub-team can measure to help understand when there are different levers to pull. Here are my recommendations:
I have a quick question though. Do you know of any copywriting courses that can help me copywrite in English for an audience that has English as their second language? It is a tricky one as obviously not only the audience´s level of English but also their culture and their mother tongue would dramatically influence their interpretation of the copy.
Content writers may need a bachelor's degree or higher. Many employers hire writers with degrees in English, journalism, communications, or creative writing. Depending on the subject matter, content writers might need a degree in a particular field. For example, a content writer creating content for an online math course might need a degree in math in addition to demonstrating solid writing skills.
The first thing you want to do to answer this question is write down each of the product’s features. You may not end up using all of them in your copy, but at the very least, you want to record them all in one place so you have them at your fingertips if needed. Some products have a lot of features, others have less. Either way, list all of your product features here with a short description of each.
Your specific needs might vary -- for instance, perhaps you need subject matter expertise in your writers, or coding experience from your long-form content creators. Or perhaps your titles differ, and your "content creators" are actually "content strategists", or your "social media manager" is really a "specialist." Make edits as you see fit, but these frameworks should be helpful in getting you started if this is your first time hiring for any of these positions.
Another option is to focus the ad on the pleasure customers experience from saving money. It could use a headline like this: “How Will You Spend the Money You Save Using [Specific Car Insurance Company Name Here]?” Instead of focusing on the pain, it draws attention to the pleasure experienced by switching to a different insurer (which is what GEICO did in 2008 with their “the money you could be saving” ads).
