Your advert, if accepted, will be entered into a rotation system whereby each page requested by a viewer will contain a banner image selected at random from our current circulation list. It will remain in circulation until the specified number of impressions or click-throughs have been reached or until a specified date. We cannot estimate how long your advert will stay in circulation. We include our own banners as well as those from paying advertisiers. We reserve the right to review banners and refuse to carry them if we feel they are unsuitable, for example we will not carry any banners with explicit adult content or directly advertising tobacco based products. We reserve the right to remove adverts from circulation at any time with extreme prejudice, without notice and without giving reason if we deem it necessary, in which case only the impressions used will be charged pro rata. Payment must be in UK Pounds Sterling. Rotation of your banners can commence only upon presentation of a purchase order. We can offer no guarantee to the effectiveness of your advertising campaign. Banners must be 468(h) by 60(v) pixels in either GIF or JPEG format, maximum of 15k file size, animated or static. Prices are subject to change at any time.
