How did you increase your trust flow?

Hi guys,

Since late January my rankings have dropped slightly (1st - 7th for my main keyword, 4th - 10th for my 2nd and 3rd keywords) and I've been trying to figure out why. I know SEO Majestic analysis isn't the be all and end all, but it would seem that my trust flow has decreased and is now less than all the sites above me. My citation is 45 and my trust 15 - has anyone had success in bringing the trust score up? Is it just a case of getting more high PR links? Can anyone recommend any services for this?

Thanks.

Trust flow is based on the quality and relevance of referring domains. This is something I've asked myself on various forums and there's no real knowledge on this out there, as far as I can see. But building links to high DA sites, EDU and GOV must be the way to go.....
