As long as you don't have the SAME article on your website, this wouldn't negatively affect your site at all. It may be a waste of time though since most of those will probably be added to G's supplemental index.

There's a couple things all mixed up together in your questions, so I'll try to tease them apart.

First off, if you submit to reputable article directories, chances are that search engines will crawl your articles on these sites. This means that

Second, not all of your articles will be indexed by Google and other search engines. Indexing means roughly that when someone searches for a phrase that appears in your article, your articles on these article directories will show up in the results. Some pages will be considered primary, valuable content, and some pages will be relegated to supplemental status (only shown if absolutely nothing else can be found) for specific search terms.

Third, all of the links on pages that were crawled will be taken into account. Obviously links on pages that were not indexed will be assigned a lower relevance. Links to your site on pages that were indexed will be assigned a higher relevance and will contribute more to your site ranking for whatever terms it is about. I honestly dont know if links from pages that are in supplemental status for a search term contribute less to the target page ranking for that term than pages that are in primary status for that search term.

So the short answer after all of this roundabout beating around the bush is: yes, links on pages that are not indexed still do contribute to your site ranking for the terms you care about.

And Rebecca is right (post #2 in this thread). You don't want to risk your site being one of the pages that aren't going to be indexed, so don't put the same article all over again on your money site.

It's called syndication ... It has been going on for years.. Even google does syndication. There is no problem posting your article to your site and syndicating it to 1,000 other places. You will still get the link juice and yes some of those can still show up on the 1st page under the same search results.

Thanks everyone! Also, how much spinning is needed for Google to consider something unique?

In my guide I go over spinning and using the tools I do to make my articles unique. I has worked for me but my question here is more to assert as to whether or not this effort is worth the time ; )

70% uniqueness is the same as completely unique in the eyes of a black and white bot

I am new to this, but James point regarding syndication makes sense. News, entertainment, and sports sites often contain the same information from the same source.

I am sure that I am naive, but even with the computing power of google it would be nearly impossible for any algorithm to detect an exact duplicate with the endless combinations and vast amount of information on the web.

no they didn't help you. google keep eye on each site. they treat all site as on individual performance.
