Say you create a unique piece of content that would be useful to every webmaster in your niche.
Technically Google should rank you on their front page

but you need to help 'em understand by getting links to your great unique piece of content

. How do you put your piece of content in front of the eyeballs of other webmasters in your field/related fields? Whats your strategy?
How do you go about "getting the word out". Ive heard emailing webmasters about it wasnt exactly an effective strategy anymore...
So how do you do this? I assume by posting on forums and getting a reputation on some forums related to your niche.
But does this really work for acquiring links?
How about using Adwords or Adsense ads?
Has anyone tried running PPC campaigns mostly in order to make webmasters in your niche know about your great piece of content and "get it rollin"

?
How about using Adsense ads and have them displayed on blogs of niche bloggers..that would put your site in front of the eyeballs of those bloggers (and their visitors) who probably look at their site quite a lot and might be curious to find out what your site is about (if you use some enticing copy).
Has any of these strategies worked well for you?
