A lot of questions, so let me try answer them all
@ TheStrangeFruit - not necessarily, quality is the most important factor. Streaming sites have died down since Flippa changed their rules, so wouldn't recommend those
Personally, Wordpress blogs with a decent PR and traffic have sold very well for me.
@ ChockFactor - yes, that is correct. Featured is the only add-on you would have to reapply (or Tweet, but never tried that). I only recommend featuring to get extra exposure, but if you have a lower end site, there is no reason to feature it straight away, let it run a day or so and if you get no bites, bump it to the front page
@ Rocsk79 - if you have a read of the flipping section I believe there was a thread where myself and some other members addressed this questions.
@ Thenayr - tough to say, although something around $3k could be about right.
@ Kudlit - congrats on your sale! I've never built an autoblog to be honest, I'm sure there are some great threads around regarding them though. When it comes to selling, I would emphasise the fact that it requires no work to add content and other than that just follow the general rules I outlined in Flipping 101.
@ DailyTrip - nice site. Yes, I would definitely recommend a front page feature, you've got a great site you want as much exposure as possible. I would also recommend reducing the listing time if you want to sell it asap.
@ GimmeTheLoot - Flippa does it automatically, and I use a plugin for FireFox (SearchStatus) which works great. Tami's recommendation looks good too.
@ Tami - I need to reply to your PM, bear with me
@ MakingFastCash22 - I like Scrapebox, but I'm not really a SEO guy. Works for me though. I mainly offer SEO services as an incentive to buyers to BIN a site.
As I mentioned to Kudlit, I have no real experience with autoblogs, there would be better people to ask than me
Hope that answers everyone's question and apologies for slow reply, been busy!
