Does article submission web-sites have any impact to SEO in these days? There are a lot of good/not so good article submission databases, but does it really matter if you spend a time to write unique articles for them? I mean, is it a good way for link-building, or should I spend more time for other parts of SEO? There are also a special websites (for example SubmitYourArticle) which automate this process, does it make sense to use this services? Alternates? Lots of questions… Update Sorry, I found some good answers only after that I posted this question.
