Ive been using SEC for about a month. This amount of time is too short for real results but for a month Im getting about a hundred targeted visits a day (include the week to get initially spidered).
I researched a lot before buying and knew I needed to devote my time to tweaking it so the unique factor is high and the content is good and plentiful.
Smart thinking w/ the templates addon and using custom templates is key. Yes, I had to buy several addons. IMO, it should be sold as a package but whatever.
I have NO vested interest in the product.
Im currently setup on 6 domains - all very different subjects/businesses. The first one I did is the one that is up to about 100 a day, the rest are following the same pattern given their later launch date.
Its not a silver bullet, but put in the time and the "thoughts", and Im comfortable saying it will work for anyone in mid-competitive keys - only because I only deal with mid-competitive niches.
