Are Article Submission still useful in SEO ?

YES! Ofcources it is useful.

 

Modification in seo. Now in 2013 most strong link building tool is article submissions because google want relevant back links and through article you can write relevant article and embed link in that article. so i think it is most useful tool for link building.

 

I agree, since the update in google mostly articles with backlinks are affected, it loses the value of backlinks however you can still have traffic when your link was clicked

 

Article submission is useful if you write a good article with moderate keyword density. Also post Panda and Penguin submit your new articles to just 1 or 2 sites at the most.

 

thanks for all such informative responses

 

I think so. Article submission is a passe these days. Even Squidoo has become no-follow, so what's the point in submitting articles to these directories. Best is to write good content and then post it on your website. At least it will get more visitors and add value to your site.
