My listings go up and down like a sin ~~~ frquency is 15 to 30 days...
Anyway, Google rules
However, they are going to the BAD direction from the point of view adult webmaster... Sure they are now vital source of SE traffic for many of us - but how long? I'm waiting very scared the day when they mess everything like Altavista.
Do we need to extablish a whole new SE
Itīs not a joke...
