How come my site is in the first 10?

Do link building for your forum with a good keywords which you want to come in the google

then check
it will really effect !

 

first search relevant category for your. then submit your site in Dir, then start doing SMO and side by side start writing article for you product and site.

 

yea,use google analytics

 

Undoubtedly it is possible to get a good rank in search engine within less time, only if the competition is low. And your site is in top 10 because you chose a phase "cosmetics forum" which is less in competition and its global monthly search volume is also low, 1900. moreover you have the same phase "cosmetics forum" in your domain name, that's the reason of your site in top 10s

 

The domain contains the keyword so it is heavy in the rank!

 

I don't think the monthly search volume matters, what matters is how many sites are targeting/containing that same keyword.

 

What about your rank with just "cosmetics"? I think the "forum " keyword increase your rank.

 

It's probably because of you domain name and title and there is no competition for that keyword.
