Insurance products easily led the most popular search terms for Warc's agency subscribers during the last year, with "life insurance" and "insurance" the first and third most widely-used phrases respectively.

"Life insurance" was the runaway winner, scoring almost twice as many searches as any other term. (For more details about the most popular material featured on Warc in 2011, click here.)

Marketers at media agencies, ad agencies and research agencies were also interested in new media channels, with "social media" finishing second and "mobile" in fifth.

Despite the economic volatility experienced in 2011, aspirational marketing remains a strong trend, with "luxury" the fourth most searched-for term.

With "The man your man could smell like" campaign still gaining viral traction, "Old Spice" was the top brand search, in seventh place. "O2" and "Nike" also finished in ninth and tenth places respectively.

Meanwhile, "beer" was the only product category to make the top 10 this year, finishing eighth.
