Develop your own area of expertise – remember that people join YOU not the Company so you need to learn to market yourself. Traditional sales techniques have a place, such as good business cards, fliers, leaflets, information sheets etc. Make sure your contact details are on everything, including every product you sell or lend or give away. Your company may have constraints on wording so pay attention to their policies. You need an online presence, ideally linking a web shop with a blogging presence and social media. Learning and updating these can be time consuming so take care to limit and control the temptation to spend all your time relating to the computer rather than the activities you committed to and interacting with people!
How am I doing? Hope this helps!
