1. I guess you'd agree that PPC competition is likely to be at least similar to organic competition? Lots of searches (according to the AdWords keyword tool) but
next to no competition.
2. When I
ordered the incoming links in order of PageRank - the top one was a
PR4 with the anchor text '
Finance' - and this was
NOT an article. The second one which was not 'nofollow' (
PR3) was
not an article either, the next seems to be
a redirect (I think) - so
again not an article.
This site is not (IMO) ranking a
competitive keyword - and although the links may have mainly been obtained via articles (quantity)... THE MOST VALUABLE ONES (quality) have not.
Article marketing (via 'Free For All' sites) is not a good way to rank a site.

I actually got into doing SEO after I employed a company to do it. They said 3 months for this, 12 months for that, etc. They mainly used naff links month on month. They got me a few results, nowhere near target - and they kept saying how they had "always got results in the past", "results take time", "proven methods", etc. but held me to the 'no guarantees' part of the contract (maybe fairly).
I was talking, pretty much by chance, to a rather 'big time' SEO - who asked me what they were doing to achieve results - so I explained. He said they may never get results due to the quality of the links and said that he would get me 8 quality articles (then another 8 a fortnight later) to show me the difference. Within a month I had top 10 ranks for dozens of words I'd been 'longing' for, visits substantially up,
making money for the first time on the site.
I have trained with this guy and his associates (and in part work for him), trained others myself (to a smaller degree) and am confident, time after time of ranking sites successfully in a very short time.
My days of using/searching for any very low value links are behind me (unless Google decides to favour spam for some reason - then I'll go back

). I find it a waste of time and that time is paid for by clients who want a good ROI.
