The article submission ship has sailed, as of the most recent Google algorithm updates.
This web page is a pretty good example of why article submission failed as a tactic. It began as a reasonable marketing practice -- create good content about your website/product/service, and submit it around the web to lots of different sites. But the burgeoning "article submission" industry ended up kind of like this webpage -- spammy marketing junk posted all over the place, without rhyme or reason.
I mean, really - who wants to read something like this on a trivia site like strange questions??? It's obvious that this person's only purpose for posting this question and answer was to advertise the article service.
If an "SEO strategy" doesn't add value for the reader, then it is doomed to fail eventually.
