Do a search on all the major search engines for san diego escort...then do a search for escort...cross reference and the ones who come up most frequently are the ones you want to advertise on...once you have been placed on their ad sites you will get alot of offers for free or reduced priced ads...take advantage of them and always ask "where to you findme?" Things change form month to month and todays great ad site can be tomorrows waste of money.
