One Citizens Advice page shows in real time what individuals are searching for on the website, what searches from the search engine Google caused an individual to reach the Citizens Advice page and what Citizens Advice website content is most popular. Citizens Advice also runs a consumer helpline to help with consumer issues. The most popular areas of enquiry are benefits and debt with housing the third most popular enquiry area. Each Citizens Advice office operates differently. Some will have specialist staff that deal with certain cases such as debt or housing. Some operate a 'Gateway' system which means clients are booked for advice at a later appointment and other Citizens Advice offer 'drop in' Generalist Advice sessions. At some Citizens Advice offices solicitors may offer short appointments on a "pro bono" basis as a way of gaining clients.
