I'm new to this, but I think yes. When I started out I desperately needed money - any amount of money. So while I didn't go below the average rate of escorts in my area, I went below the average rate of escorts in my "target group" (young slim girls) and I got flooded by responses, I see how other girls with higher rates and women with rates like mine but less service or less "mainstream" type of women have to constantly bump their ads, but I never have to, my clients do it for me. Of course I think a big part of it is that I'm new, however I live in a very big city and there are plenty of new very pretty faces each day, so I really think it's the price that attracts a whole lot of them. Of course, as you can read on my thread not every guy is an actual good and normal paying client, so I'd have to get the hang of filtering out timewasters and creepers but yeah.
Now that I paid off my bills, in 1 week nonetheless, I'm thinking of actually raising the price, but that will probably result in a lot of protest and heckling haha.
During your first year at least you are kept busy through business on AW. It used to be about 2 years but with the saturation of unemployed girls joing the ranks of prossies it is getting harder.
During your first year you should try and prepare yourself for a lot of work drying up and getting yourself listed on lots of other free sites and getting yourself known.
When I started on AW 6+ years ago we had a minimum of 1000 hits a day and now we are lucky if we get 300 or so, so a big difference.
