Opt-in panels may have lower response rates and may not be representative of the population, while invitation-only panels allow for better sampling and recruitment of specific target groups. However, it is important for panels to identify and remove "professional respondents" who may participate in surveys for financial gain rather than genuine opinions, as this can skew data and undermine the validity of research.
