I've sat at number 8 for a long time now, really just giving up on the website. It's not huge traffic but when it was at #1 it was a good $10 a day revenue, I'm talking about the big G of course. 1,300 local searches, 3600 global, $2.11 CPC
After a couple of months at # 8 I decide I'm tired of seeing it at #8 last week. I start taking 1 page or blog post a day and updating the on page SEO.
My website has now jumped to #4 from # 8 after 7 straight days of this. No backlinking has happened at all.
I'm done being lazy with my onpage SEO.
