Referrals\/Word of Mouth\n\u201cFor most businesses, the best lead generation strategy is to focus on getting repeat business and referrals from the customers you've already won,\u201d says Branndon Stewart, CEO, OutboundEngine.\nBesides offering great service, provide loyal customers an added incentive to come back, such as 10 or 20 percent off their next purchase. Similarly, get them to refer their friends and family (and colleagues) by including a friends and family coupon with their order.\nAnd don\u2019t hesitate to ask clients to refer you to their friends, family and colleagues. (Don\u2019t ask, don\u2019t get.)\n\u201cOne of the best ways that I find gets new leads is to ask current clients to refer us,\u201d says Allan Madan, the founder of Madan Chartered Accountant. \u201cWe do get no\u2019s, but from the people who do refer us to their friends or family, on average we get three new leads from each client who refers us.\u201d\n2. Free E-Books or White Papers\nProviding useful information for free helps \u201cmake consumers trust your brand,\u201d says Lisa Chu, CEO, Black N Bianco, which provides formal wear for boys and girls. \u201cBy offering quality educational content regarding your niche, your brand will organically attract those in your target audience.\u201d\n\u201cYour company\u2019s lead magnet could be a free e-book, template or webinar,\u201d adds Jeanine Blackwell, CEO of 4MAT 4Business, a performance improvement and brain-based instructional design company. \u201cThe trick is to deliver the resource in exchange for a prospect\u2019s email address, which fills your sales funnel with potential clients.\u201d\n3. Webinars, Live Chats and Hangouts\n\u201cOne method that has been successful for us and is also very cost effective is webinars,\u201d says Robert Armstrong, cofounder and CEO of Appstem, a mobile design and development firm. \u201cWe choose a topic relevant to [our audience and discuss] trends we see or industry pain points \u2013 and invite a few of our technology partners to join. It\u2019s a great way to create value for industry related people and introduce your company.\u201d\n\u201cWe generate over 3,000 leads per month, mainly for free, by offering free webinars,\u201d says Ray Higdon, a marketing and lead generation expert and founder of Top Earner Academy. \u201cThen we take the webinar recording and place it behind a capture page,\u201d which results in additional leads.\nAnother way to attract potential customers or clients is to conduct a Twitter Chat or \u201ccreate a Google Hangout on a topic that connects with the needs of your target audience,\u201d says Jeff Beale, aka Mr. Marketology. Show the audience \u201cyou understand their needs, and how you approach a solution and the benefits of that solution,\u201d he says.\nWhen conducting a live Twitter Chat or Google Hangout, it\u2019s also important to respond to questions promptly and provide participants with contact information, where they can get in touch with you or learn more after the Chat or Hangout is over.\n4. LinkedIn\nLinkedIn can be a great way to find potential customers, if you know what, as well as who, to look for.\n\u201cWhen searching for potential clients on LinkedIn, use specific qualifiers such as geography, common education or previous work history,\u201d suggests Brian W. Sullivan, vice president, Enterprise Selling, Sandler Training. Similarly, identify companies or organizations that may be relevant and \u201cmine the entire enterprise for insights, leads and connections that can help you develop the relationship.\u201d\nLinkedIn Groups are another source of leads. Join Groups most relevant to your business, or where you are most likely to find people interested in your product, service or expertise. Then \u201cparticipate in Group discussions by being a resource, sharing best practices and knowledge gained from experience,\u201d says Lydia Sugarman, president, Venntive, which provides a digital marketing platform.\nFinally, \u201cfollow up with people who\u2019ve made interesting comments [on your posts or related posts] with personalized emails and schedule a call or coffee to connect and build the relationship.\u201d\n5. Facebook\n\u201cRather than throwing money at advertising, SEO and other services, invest in valuable, engaging content and distribute it via social media [sites, such as Facebook],\u201d says Stewart.\nHaving a company Facebook page and providing fun, helpful or informative content of interest to potential (and existing) customers \u201cis a great way for business owners to build credibility, nurture customer relationships and increase marketing ROI.\u201d\nAlso consider Facebook ads.\n\u201cWe've found Facebook ads effective for both B2B and B2C purposes,\u201d says Brian Carter, an author, speaker & consultant with The Carter Group. \u201cFacebook ads [give you] access to hundreds of millions of people, [offer] more than a dozen targeting options and [are] low cost.\u201d Moreover, \u201cFacebook can automatically find people within your target audience that are more likely to convert.\u201d\n6. YouTube Videos\n\u201cVideo content can be a boon for email and demand generation strategies, and some studies have shown that simply including the word \u2018video\u2019 in an email subject line can increase click-through rates by more than 7 percent,\u201d says Brendan Cournoyer, director of Content Marketing, Brainshark, which provides a sales enablement platform.\n\u201cVideo can be used in a number of ways to support lead generation,\u201d he continues. \u201cYou can create short video teasers for a new [product or service] or repurpose live webinars into on-demand videos that visitors can register to view,\u201d he explains. \u201cAnd with today's technology, practically anyone can create effective video marketing content like this quickly and easily.\u201d\n7. Third-Party Lists\nIf you are a new business looking for certain types of customers or an existing business launching a new product or service and looking to find potential buyers, buying third-party validated data (aka lists) can be a good option.\n\u201cFor example, if you sell iPhone accessories that assist people with live navigation while in their car, knowing that they drive a car that is Bluetooth enabled [is a valuable] piece of data that you may not have access to otherwise,\u201d explains Ted Prince, senior vice president, Information Services, Neustar, which provides real-time information and analytics.\n\u201cAnother example when validated third-party data can be extremely helpful is when a company decides to open a new retail outlet,\u201d he says. \u201cThey would want to know the density for potential buyers [or buying patterns or average income of the population] before they make a large investment.\u201d\n8. Google AdWords (PPC)\nWhether you are a new business, especially a new ecommerce business, looking for customers or want to attract Internet users to a new product or service you have on offer, Google AdWords can help you find potential customers quickly.\n[ Related: How Ecommerce Businesses Can Beat the Competition in 2015 ]\nSigning up for Google AdWords is free.
