Have you configured your site in google webmaster tools to be counted towards the country you're trying to rank it for? (Just because you're targeting some english term doesn't mean google understands you're trying to rank for that term in your country, not in the US, for example.)

On that note, is your site hosted on a server in the US or your country? (This shouldn't make too much of a difference if you configured your site in webmaster tools to target your country)

How old is your site? (The younger it is, the more it can possibly dance around or take time to rank, especially for competitive terms).

Does it have any kind of penalty for bad things you did onpage? (I guess that one is obvious. You can do a very very broad/general check for a penalty here: Penalty Checker)

Did you use your keyword as your anchor text for the backlinks you've built? (You have to do that in order to tell Google what the target site, yours, is about. So if you're targeting "blue widgets" with your site, you have to build links like this: blue widgets)

Are most of those 1000 links that are showing perhaps "nofollow"? (If they are you're just wasting time, they don't help your rankings.)

Is the keyword competitive? How long have most of the domains ahead of you been sitting there? (The longer sites have been sitting in their places and the more competitive a term is, the longer it could take you to outrank them.)

I hope that gives you a few ideas to check up on and catch something that could cause low rankings.

How exactly are you building links and what type of links does your competition have? In other words, if all your doing is buying backlinks on snippet sites and your competition is building links through press releases, this is not apples to apples.

Content is becoming more of a factor. How many people are putting up 400 to 500 word articles on their sites? Everyone is. To get some Google love create large amounts of text (1000-5000 word articles) and interlink all your pages well. If it works for Wiki, it can work for you;-)

Of course Backlinks are king, but hey if you can get large amounts of content it wouldnt hurt.

i think link building is all about quality not quantity, do quality work on forums and article submissions, these will help you to get website high rank

Make sure you use H1 tags and your Keyword density is good. Also quality backlinks are important from high PR sites. Make sure you use WOORank.com its free and it can determine how well your site is optimized.

Hope this helps
