Only 20.5% of surveyed mid-market technology companies have a corporate blog, according to a survey from Percussion Software. However, software companies, particularly smaller ones, are far more likely to have an active blog.

Below, additional findings from the study titled "The Paradox of Blogging and Content Marketing," based on a poll of 806 tech companies. 

Among those 20.5% of tech companies with a corporate blog, 73.9% post new entries at least once a month, whereas the rest are relatively dormant:

Larger companies have more blogs 

Larger tech companies are more likely than smaller and midsize ones to have an active blog.

Only 15.6% of smaller companies ($20-25 million in annual revenues) have a blog, compared with 19.4% of midsize companies ($30-49 million in revenues) and 25.3% of larger companies ($50-100 million in revenues).

Software companies lead in adoption

Software companies were among the earliest adopters of blogs, according to Percussion, and that appears to have contributed to their current affinity for blogging: 42.8% of surveyed software companies have a blog (vs. for the 20.5% tech sector overall).

Smaller software companies (less than $20 million in annual revenues) are most likely to have a blog: 55.1% of those surveyed have one.

About the data: Findings are based on a survey of 806 mid-market technology companies, conducted in February 2012.
