Esearch.com started building an online panel for market research purposes in 1995. It was one of the Internet's first panels supporting research, and has grown to be one of the best. The Company has grown up on the Internet and fully understands all the idiosyncrasies of this booming medium.
Demographic information is collected on each panel member so researchers can specify exactly who they are looking for to fill a given study. (For a list of demographic variables available, visit the signup page) . Queries are made and email invitations are sent to the target group. Groups can include:
- Business Executives
- IT Decision Makers
- Targeted Ethnicities (African Americans, Hispanics, etc.)
- And others
We realize that each job has specific demographic requirements so specific profiles can be provided, or Esearch.com can pull sample based on US Census data - pulling stratified samples by specific census information. Further, DMA and other specific identifiers can be appended to the data file after data collection for immediate or future analysis. If a client needs a nationally representative sample, Esearch.com would pull the sample based on this (although fielding online tends to be higher educated, high income groups). Results can be weighted when it is a requirement. Most typically online studies are looking for very specific people and in these instances the sample (by definition) isn't representative of the US population... nor does weighting matter.
Specific advantages to using online panels for research include:
- Samples can be very targeted (women age 45+ with an income over $60K)
- Specific or low-incidence segments of the population can be found quickly
- Surveys can be focused and demographic information added to the data from the panelist database
- Non-response can be calculated and the information used to estimate any sample bias
- Panelists do not select themselves for individual surveys but for the panel in its entirety
