Hi everyone, new to forum. I've noticed over the past month that a few of my domains are slowly dropping. They were in top 2 - 3rd position under competitive words. Now the have dropped to 6 - 8th position.

my questions: anyone else running into this?
Will i have to go chase down more links to my sites?

I hate wasting time adding more backlinks to my sites, i would rather
spend my time building quality content.

any help would be most appreciated.
