As an intern, I wrote blog posts and product texts for different companies to help them improve their SEO. I wrote the main text in Google Docs and later put it into WordPress. I wrote about five blog posts, each for a different company. They all contained about 500-2000 words.
What I learned during this was that there is always something to write. I just had to think from the reader's perspective. What questions do they have? What would make them excited about this product?
For example, here in Sweden, we can embroider text on our graduation student cap, but sometimes you don't know what to write. Because of this, I decided to add a section about different things you could add to your graduation cap.
