What type of links next?

I have a website that I am using for the "Dentist" method that was posted on here a while ago.

I currently have an EMD with hardly any information on it (I'm too busy writing articles for clients to actually get round to throwing stuff up yet).

It was ranking #8 on .com and #42 on .co.uk with 0 backlinks.

I ordered a 2000 article directory on fiverr, and this has took it to #2 on .com and #14 on .co.uk

What type of links do you think i should try next?

I was thinking of trying the EDU service available on BHW for $15.
Any recommendations?

Can you share with us what was the gig you ordered? I also suggest you to get all types of backlinks, add diversity but I assume you already know this

Thanks

Throw some blog blast at it, forum profile blast, social bookmarking links, web 2.0 links, etc.

Mix it up...no follow/do follow - High/Low PR links.

I would setup a drip fed series on it to keep the links slowly building up as well.

The main thing is to keep it looking natural to big "G"
