I have just spent hours going through all the recommendations for adverting here and thought it would be helpful to sum up the costs etc on a more recent post for anyone interested.
Viva Street - free option, paid option - most of the ads look fake and it would be easy for your advice to get lost in it all.
Punternet - 15 / 30 per month - doesn't look as though it gets used very often due to lack of ads, not for Scotland anyway.
My local escorts - 9.95 / 34.95 / 44.95 per month - looks like a busy site and could get some work from it. Will definitely sample this one.
Punterlink - 60 per month minimum (depends on location) - doesn't have many ads on it and seems to be used more by agencies to advertise their girls. May be worth a shot but I probably won't use it at that price.
Select an escort - couldn't even navigate the site to find pricing and it just hurt my eyes to look at it.
UK Belles - free - have to request via email to have an ad, but weirdly the email link doesn't work. Unsure if this site is still "active".
Escort pages - no longer active
Punting zone - no longer active
Ukadultzone - free and paid for options - looks alright for a free ad!
Girl-directory - free - again, worth it for a free ad.
sexy independent escorts - 20 per month - doesn't seem like a good advertising platform for my area but could be ok for others.
worldescortguide - banner exchange - looks quite decent for attracting non UK clients, worth a try for a banner exchange.
bellesescorts - free - may aswell stick an adult on if it's free!
openadultdirectory - banner exchange -
escort-scotland - couldn't find prices but if I remember correctly from previous visits, it's around 60 - 80 per month - busy site but all ads look professional photos, no selfie types so would need to prepare for that competition if placing an ad.
topescortbabes - free - didn't have many ads for my area but again, it's free so may aswell try it.
Slixa - mainly a US site but have 4 UK locations including London and Glasgow. The Glasgow section isn't operating yet but hopefully soon as the site looked quite well maintained and a popular site for US clients when visiting UK.
OK, that's about all I managed! There are some decent options in there if you want to avoid using Adult work, but the sad realisation for me is that it's a necessary evil. I will definitely be padding out my marketing with a few of these sites in the next month and will feedback on the response I get.
