A new division, called Maktoob Research, will help market researchers to contact hard to reach individuals such as Saudi women and Emirati businessmen.
The panel exclusively consists of Arabs aged 20 to 45.
These individuals have traditionally only been reachable through expensive and time-consuming face-to-face and phone interviews.
Although online market research is widely used globally - representing up to 50% of the research conducted in some parts of Europe - most Middle East research agencies are still using more traditional methods.
The launch follows last month's announcement that YouGovSiraj is to build a 75,000-strong online consumer research panel in the region.
Ahmed Nassef, general manager of Maktoob.com and vice-president of Maktoob Group, said: "The region's marketers and advertisers are demanding fast and accurate answers about their target consumer segments in order to make informed decisions.
"Maktoob Research's unmatched database of consumers from every corner of the Arab world will finally empower marketers to get to the right audience quickly and more economically ."
Nassef added: "Online research is a trusted and integral part of the market research industry worldwide, and we're excited to finally bring this key tool to the Arab world."
Maktoob Research will enable users to research their target audience by demographics and behavioural patterns. This will give advertisers detailed information about the lifestyle habits of their target market.
Tamara Deprez, research director, said: "We can pinpoint the right target audience and deliver high quality online research solutions by providing a full range of marketing research services from design to analysis and action-focused recommendations.
"Maktoob Research aims to deliver online market research at much lower costs and with a faster turnaround time than traditional research. We are confident that this form of research will pick up pace very fast and are proud to pioneer this in the region."
Maktoob.com's network covers more than 30 countries, including the UAE, Saudi Arabia, Kuwait, Jordan and Egypt, as well as markets that are more difficult to reach, such as Sudan, Algeria and Iraq.
Maktoob Group has merged its marketing information portal Strategiy.com into Maktoob.com. From now on, Strategiy will be known as Maktoob Business.
Registered users of Strategiy will now get access to Maktoob's services, which include an e-mail account and blog space. Several new features are also planned.
Founded in 2000, Maktoob.com has four million users, of which 75% are surfing in Arabic.
