Study: Company Blogs Lead Social Media Options

Only 16% of those surveyed said they trusted company blogs.

Volpe distinguished the HubSpot results by pointing out that the marketing-related professionals surveyed by the company were mostly from small and medium-sized business, which he believes tend to have more credible blogs.

"In my opinion, smaller companies are doing a better job being more authentic and don't have to vet every post so tightly before it goes up on the blog," he said. "That perhaps makes their blogs more successful and more trusted by people."
