In Panda updates many of the article sites dropping down like Ezine article,article dashboard etc if i submit the article in these sites, does any negative effect on my site. Can i stop the article submission? All suggestions are appreciated. Thanks.
No, incase you've unique article on directories it wont have any effect if they have duplicate content then you must be worried about it.
From here on in, we have decided to treat article submissions just like we treat bookmarking sites (solely for the purpose of getting a page indexed). We expect the links to hold little if any value. It definitely won't hurt your site, but it won't help much. If it were able to hurt your site, don't you think I'd have a million articles submitted for all my competitors by the morning?
You can use article submission websites for getting backlinks.... But as far as promotion is concerned, it won't give any effective results. Because Google will index your article but it will not display duplicate content in search results. To make your article submission strategy successful, you can spin your article and submit it to the article directory (of course, after making it readable for your readers, as automated content has some flaws)
