Motherboard is the most complex component in a computer as it has hundreds of components and each of them has distinctive function. To choose a right motherboard, the CPU socket will be a good place to start. If you have decided on the make and type of CPU, it will be easier to find out the socket type that it supports. For example if you pick Intel i7, it supports LGA 1155; LGA 2011 & LGA 1366. You may then focus on the chipset features used for a particular type of motherboard. The north bridge chipset governs the CPU, RAM and Video and many of them may embed onto the CPU already. In the mentioned example, you may choose Intel Z77, H67, Z68 and P67 chipsets.
