Hi Sarahh, I’ve moved your question to this area of the forum where it is better suited. In fact, if you look through this area you’ll find some good advice about advertising your site.
I personally find that Panty Hog is the best place to advertise. If you fill out your profile, post regularly, complete your Member’s Page and post some pics in the Member’s Gallery then the buyers will be falling over you.
The second best place is Panty Trust, I get a lot of traffic from there too.
Then of course you get traffic through links with other panty sellers.
Try directories like kinky-links too. Oh and there is PantyManMagazine but I hardly get any traffic from there.
