Interesting question.  I looked at the ads mentioned and came to the same conclusion within a glance or two - before I started to actually analyze it.  I thought it was interesting that I had that sort of reaction and I thought I would try to explore that a bit and see if my subconscious reaction seemed right.

FULL DISCLOSURE: It could be these girls are completely legit.  I really don't know.  Just my opinion.

First ad - Darlene - looks like a lingerie model - possibly for Victoria's secret.  Telephone is outside area code - no rates - no external website. She's visiting.  Couldn't find a TER review. Really?

Second ad - Shelby - See Darlene...  

Third ad - Kara.  Kara's is much better done than Darlene or Shelby - There is an email and the blurb is better written...has a certain authenticity to it in terms of sounding like its legit.  Not interesting to me but... Still no website.. no rates.   Cute girl - strikes me as being possibly underage.... which - assuming it's not a B&S or RO is a real issue.   The email strikes out on TER....  not a good sign.  

Fourth ad - Kimberly - outcalls only. no email, no website, no rates no nothin.  The pictures at least look real -- my guess - there's a girl using somebody else's pictures.  Or possibly some really old ones.  

Conclusion - I think my reaction was right.  Even if it wasn't - I don't ignore my "spidey" sense.  

As far as you are concerned, however, the takeaway would be that you need to give me the information I need to make a choice.  Am I a typical customer? - who knows?

For me - website, screening info, rates, email address, phone number are all minimum pieces of information in addition to a reasonable photo indicating your body type and generally what you look like.   These things can be on a website even if you don't have them in the ad.  If you have a TER ID - use it on your website.  

As it happens - your website is pretty good; don't like some of the pop ups.  Free hosting has its price... On the other hand, there's no doubt in my mind as to who you are and what you do.  If the customer isn't in to BBW - you really aren't a good fit.  That's a good website.

As far as pictures - variety is always good - and that would be the only criticism  that I have about your website.   There are a number of girls who are active on this board who have really good websites
