A sizeable minority of bloggers have written paid posts, a survey by the Melbourne-based Problogger website suggests.
The respected site has been asking its visitors whether they had ever written a paid post.
The survey is still live, but with nearly 1000 respondents so far, 6.4% say they do them regularly; 13% say they do them occasionally and a further 8.2% say they used to, but have since stopped. The other 72.4% said they have never done so.
The issue of paid posts is a controversial one. Some brands pay bloggers because they see it as a good way to promote their products. Others do so in order to get links to sites which will boost their value in the eyes of search engines.
However those who do so and are found out by Google risk seeing the Page Rank of their site downgraded.
