Will submitting one article to many hundreds of article submission sites wit hnon-reciprocal backlinks make a lower impact, compared to if you release a unique article to each submission site. Will search engines see the repetitive content and basically exclude any relevance to it? It would be faster and easier for a one or a few articles. But anybody have experience in seeing results on a large scale of hundreds to over a thousand article submissions? Thanks
unique for sure. or atleast spin the article with some manual edit so that it doesn;t look same or you will be penalized for duplicate content
Article submission sites are a "waste" of unique content for your own site, I would avoid this beginner backlink building method and work on geting quality related backlinks to your site.
I tend to agree ssandecki that submitting a high quality article is a waste of unique content. But the standards of these article directories is lower than I would put on my sites. Sometimes it can be quick to write a basic article for submission of the top of your head that I wouldn't want on my own site. Definitley mass submission. Try 2: mass submitt 1 article, then try another where you spin it. Test the effect. If you want to spin this can be done efficiently with JetSpinner/SetSubmitter or ArticlePostRobot. I'm not sure article submission would take any serious serps, but it can help get the backlink count up.
