If your company is business-to-business (B2B), your digital marketing efforts are likely to be centered around online lead generation, with the end goal being for someone to speak to a salesperson. For that reason, the role of your marketing strategy is to attract and convert the highest quality leads for your salespeople via your website and supporting digital channels.
Be aware that Google's recently cracked down on guest blog posts and guest blog tools that focus exclusively on attracting links. While links can be a nice byproduct of a relevant, useful, and high quality contribution to another site, it can look very fishy to Google if all your links are coming from guest contributions that appear to have little relevance and low quality. Moz's Jen Lopez wrote an excellent summation of the new rules for guest posting here.
To do that, you need a consolidated view of customer preferences and expectations across all channels – web, social media, mobile, direct mail, point of sale, etc. Retailers do this using omnichannel retail analytics. Marketers can use this information to create and anticipate consistent, coordinated customer experiences that will move customers along in the buying cycle. The deeper your customer insight into behavior and preferences, the more likely you are to engage them in lucrative interactions.
