How frequent Dneero provide survey ?

it depends on some requirements i guess, like your location, etc. in my experience, i guess i receive survey offer once a week.sometimes twice.it really varies from time to time

it depends on requirements. even i am registered to many survey sites but then again due to market conditions and the demographic requirements the surveys have become less... rather scanty and therefore it takes a while ... for now more that 2 months to even get 1 survey... i am still waiting for my turn.. donno when it will come.

I guess it depends on the demographic requirements, different surveys have different sets of requirements. So, it's hard to say how frequent they provide the survey, it's just the matter whether you are qualified for certain surveys. I've seen there's a active survey which is applicable for females only.
