I write articles my self. Can I post same article about same topic on different directories at the same time?
No in my views especially after Google Panda Update. Google Panda checks for duplicate content. Though you would own the content but same content would be present on so many sites which in return will harm your site. I will suggest you going for spin articles or if you can afford write one article for each directory. Submit in less but submit quality
Yes, no problem. I think you should post your article at your website. When google indexed it (after 7 days ), you can post your article for many article / press release website. It's call article syndication.
you mean to say that we should add an article on our own website first than we can add the same article on article directories as well... m i right ?
