I have obtained the 3rd position on Google, however I am not in the top 100 of ATW or Hotbot? How could this be? I don't expect to be 3rd as well on the other Engines, however not being in the top 100 in making me worried?
I had the same experience listed then dropped but retained all the back links and even a few content pages. I wrote a polite letter to ATW and 2 weeks later i have a reply the same day they spidered the site so I am hoping they will like the content and list it. - Clean site no hidden ploys or spam and good and improving rankings on other SE's.
I could be wrong but I don't think this is anything other than a paid inclusion issue. I have a bunch of #1 - #10 sites in google, all of them show substantially more backlinks in ALW than google and yet less than 1/2% of my traffic comes from ATW. ATW knows full well about your sites, they are just waiting for you to pay your Lycos/Fast yearly dues per url and you're in! Or you could just wait it out, who knows, they may start showing your sites someday.
It could also be a filter problem. Default the filter for adult content is on, but sometimes ATW has false positives (page is filtered although it has no adult content). To find out, try a search with filter off.
