I'm a freelance content writer and I was wondering which are some good, ideally free, tools to improve the SEO of my written content?
I have been making my first steps into SEO recently. And after searching around the web a lot, I have had some trouble in finding good tools. Recently certain services started asking money for basic things like keyword search for example, and most articles about the topic either don't apply to me or are out of date.
Good to note: I have little back-end control over the sites I write for. I generally just deliver a Google Docs/Word file to my clients.
So hope that was clear, if it wasn't feel free to let me know.
