According to a new report from Forrester, summarized by MarketingProfs, only 13% of B2B interactive marketers say they have increased online display budgets in 2011 relative to 2010 levels, in large part due to perceptions of ineffectiveness.

71% of B2B marketers surveyed say they used display advertising during the fourth quarter of 2010, whereas 86% of B2C marketers reported doing so.

Attitudes toward online display are negative, particularly toward ad exchanges, DSPs (demand-side platforms), and ad networks:

• 27% of B2B marketers say they anticipate increased effectiveness of display advertising via exchanges over the next three years
• 21% expect increased effectiveness of display media via DSPs over the next three years
• 16% expect increased effectiveness of display ads via ad networks over the next three years

Given lengthy and complex purchase cycles, says the report, most B2B marketers focus display efforts on increasing brand awareness, lead generation, reaching key target audiences, and driving direct sales.

Only 20% of marketers focus display efforts on increasing site visits (e.g., using campaigns to drive clicks to lead-securing and nurturing opportunities such as webinars, whitepapers, and virtual events). Still fewer marketers focus display efforts on driving brand favorability (17%) and customer lifetime value (14%), observes the report.
