A simple text entry (known as a standard entry) with a link to your web site is FREE OF CHARGE.
However, to maximise the chance of a visitor clicking on your web site, instead of one of the others listed on the same page, you may want to have an enhanced entry.

An enhanced entry will include a photograph and highlighted border to make your entry stand out. It also means that your entry will appear on thesite.co.uk within 48 hours. For a limited time, this is available for only £35 + VAT. At present this is a one off fee.
