Travelfish.org does not run contextual or banner advertising.
On the previous version of our website, if you used Google Adwords you could target ad positions on Travelfish directly through the Adwords interface and they would appear in Adsense positions across the site. Now that we've removed all of these advertising positions, this is no longer possible.
We may re-assess our position in 2017, but for the time being we're not handling direct advertising enquiries either. This means that it is not possible for anyone to advertise on Travelfish, at least for now.
If you'd like to be contacted should we change our stance on this, please get in touch with Stuart or Sam.
