Sadly, I'm at #14 for the keyword phrase: TOEFL in Saudi Arabia.
I was #1 for months, rightly so - the whole website is about TOEFL in Saudi Arabia, good original content, visitors get what they're looking for, no ads, no bad links.
The competition for my specific key words and phrases is so low, THIS PAGE comes up #5 in google now, just because it has "TOEFL in Saudi Arabia" in the title! (w/ higher PR of course)
I took a look at incoming links and found that there are at least 30-40 of Russian websites linking to my site, a lot of weird stuff (porn, etc.), but here's the thing - I didn't buy any links from anyone. I am the only admin of the site! Could a competitor have gone so far as to pay for a lot of bad links to my site to get me penalized?!
