PushON is an "award-winning" British SEO agency from Manchester. PushON has first caught my eye in 2008 with their humorous commentary on the wide-spread anti-SEO sentiment of that time, their SEO Bullshit Bingo.
I have been connected to the company ever since. I have been especially following the managing director Simon Wharton.
PushON has recently introduced an alternative to call centres where the agents can work from home and the software runs everything else.
