This vast quantity of information also means that customers are no longer as interested in listening to a traditional sales pitch that doesn’t relate directly to their needs and it might even push them away. It is now important for companies to focus on generating new leads by developing a strong internet presence. This is often accomplished using inbound marketing methods that employ techniques like search engine optimisation and content marketing.
Lead generation can be an easy way to increase your return on investment and greatly expand your client base. Approach it just like you would any other advertising endeavor: set aside a reasonable budget to test it and see if it works for your business. The key to being successful in lead generation is to brush up on your sales and marketing skills so that the leads you receive convert at a high sales rate. Do not try to approach this method of marketing without the ability to follow through and close the sale.

First of all, BuzzFeed has awesome subject lines and preview text. They are always short and punchy -- which fits in perfectly with the rest of BuzzFeed's content. I especially love how the preview text will accompany the subject line. For example, if the subject line is a question, the preview text is the answer. Or if the subject line is a command (like the one below), the preview text seems like the next logical thought right after it:

If links and looks are set, begin interacting with the page. Abandon it, adjust the window size, convert. Are error messages appearing when they’re supposed to (if, for example, you don’t input all the form’s required info)? Is your CTA button working? If you abandon the page, are you retargeted with ads? When you resize the window, does your landing page respond accordingly?
