According to the 2011 State of Digital Marketing survey, SEO beats PPC and Social Media for generating leads and it is the number one source of leads for both B2C and B2B marketers.
2011 State of Digital Marketing Report was compiled by Webmarketing123, an online marketing agency based in California. During August and September Webmarketing123 surveyed over 500 online marketers in the United States, from which about two-thirds identified themselves as B2B marketers.
Website traffic is the primary way both B2B and B2C marketers measure their success in online marketing.
Both B2B and B2C marketers agree that SEO has the biggest impact on lead generation. 57 % of B2B marketers and 41 % of B2C marketers credit SEO as their primary source of generating leads.
When it comes to marketing budget, one third of B2B marketers said that SEO gets the majority of their budget. On B2C side only about 20 % said that SEO is their top budget allocation.
Interesting is that 60 % of the marketers surveyed say they plan to increase their social media marketing budgets in 2012, ahead of PPC and SEO. 53 % plan to increase their budget for SEO and 40 % for PPC.
