CGI is Computer Generated Images. Like Toy Story
Unless you want twenty punters a day, they don't need that much traffic provided it's steady? I get probably one booking a day from AW (sometimes a couple, more often none) and VS is useless in central London - it depends on where you are.
If we don't bother with other websites (many of which are free or pretty cheap provided you can give them a link on your website), then it's all on us, not the punters. I get bookings regularly from at least half a dozen other sites, and the punters are on the whole a lot easier to deal with than the AW numpties because they've put some effort in - I also hear the AW punters moaning about fake profile and fake pictures, but they still keep using the site because they're too pig lazy and blinkered to even Google. Sooner or later the ones with something about them move on, and I want to be in as many of the places they might move on to as possible.
You can likely find a diamond ring in a shitheap if you keep looking through shitheaps for long enough, but if the end result is important to you (and even though it might cost a bit more and require a bit more leg work) it's likely best to go to a jewellers in the first place. AW is just a giant shitheap.
I'll stop now, because I'm derailing the OP's thread
