I always have more citations showing in Google Scholar than in ResearchGate.
RG citations are ONLY those citations found in papers that have been uploaded to RG. Google Scholar includes any citation Google can find anywhere on the Internet.
Dear Prof. Naseer Almukhtar, it is a known fact that google has the larger database compare to RG, pick more citations, readily available to solve both educative and non educative problems but I will always prefer a medium creating a platform of opportunity for direct interaction between expert, likes minds and be in direct contact with those you so much respect in your field.
Both have common interests regarding dissemination of scientific knowledge obtained through research.
RG is a forum for meeting researchers that has greater convening power as a network to interact quickly and efficiently, with academics from all over the world, and allows to know in a short time, the results of their research through publications.
As for Google Scholar (Academia.edu), it has less call and interaction, but the publications that are disseminated on its page are excellent.
I think google scholar has a more powerful search engine and picks more citations to articles than Researchgate. Furthermore, Researchgate displays only the articles that you or someone has uploaded. Google Scholar picks up nearly all published articles regardless of where they were published
RG cites publications uploaded in its database which is often limited in numbers in comparison to goggle scholar that fetches all our publications from various online databases.
Google Scholar (GS)(best searched with Harzings-Publish or Perish) is the most comprehensive search tool for bibliography and bibliometrics in science, as it searches within the Google Scholar bibliometric database. A great majority of the scientific work is registered here, thus tracing a wide and quite complete panorama of the work realized by an individual during his or her career. It must be noted that if a production is not visible from the web, it will not be registered, and about the journals, they have to ask for their registration into Google Scholar, thus some of them are not visible in GS, except the papers that have been cited and thus are recorded, but as individual production, not as part of a journal’s issue.
ResearchGate.(RG) is based on individual registration, and thus people not registered might be low or not visible on RG, if their potential co-authors have not register their work either. From this RG is interesting when available, but its metrics are not comparable from one individual to another. ResearchGate seems to be for now the best communication tool between researchers to communicate their results and exchange results, ideas, projects, etc… Thus it is much more than an indexation and bibliographic site, it is a tool that helps research management and prospective, and accelerates the diffusion of results to the wider audience concerned by specialized topics.

RG and Google scholar use different databases. The RG recognises only publications uploaded on the site while Google scholar's database is very comprehensive, searching through the internet for possible references for its registered members.
