Content writing has other names - SEO writing, internet writing. Basically, a content writer is someone who fills websites with content on various topics and aims at reaching a specific audience. Content writers always have search engines and keywords in mind because these are sure ways to connect to the right readers and bring them to a website. Technical writing is quite different. It is all about simplifying complex things and creating instructions in different forms (online help, training documentation, user guides, etc.). So, we see that the definitions are far from being alike.
