helpx.adobe.com is only for the product documentation and articles written by Adobe employees or documentation team. What kind of article do you want to publish?
You can create a blog post in Adobe Forum though.
Thanks a lot for planning to share an article to the AEM Community. Due to some internal diversion, article publishing on Helpx is on hold.
I would recommend to post it on the AEM Community as a post and mark it as a discussion. Once done, I'll put it on featured content.
