Thank you so much for your very important question. I'd like to tell you that, in 24-April-2017, I wrote to the RG staff about the same issue and I get the following answer:
Dear Emad,
Thanks for getting in touch. We have recently turned off the manual citations/references function, and are working on creating a better way to add them that will ensure accuracy.
While citations using standard citation styles are usually extracted accurately on ResearchGate, there are some instances where they cannot be extracted – for example, for full-text PDFs that have been created from scanned hard copies. PDF as a format is not particularly standard, and therefore creating algorithms to extract this information is an ongoing process with varying levels of success. Please also note that citations that do not have complete metadata (publication date, journal, abstract) may not be included in your citation counts, as this is important information when it comes to matching citations to publications correctly. Additionally, if the citing paper is not on ResearchGate, this can also hinder our efforts to add the citation. Our citation data is regularly updated and we are working hard to improve how we extract and match citations.
We're also experimenting with a prototype that allows us the possibility of interfacing with external sources of citation data to update singular publications.

"The role of ego in academic profile services: Comparing Google Scholar, ResearchGate, Mendeley, and ResearcherID
.......
Each academic profile platform offered distinct and complementary data on the impact of scientific and academic activities as a consequence of their different user bases, document coverage, specific policies, and technical features. Not all platforms have a homogenous coverage of all scientific disciplines. Likewise, their user bases aren’t uniform either. Researchers should be aware that the bibliometric portraits shown in these platforms depend to a great extent on the individual characteristics of the “mirrors” themselves.
Google Scholar Citations profiles draw upon the vast coverage of Google Scholar (giving voice to all disciplines, languages, countries; academics and professionals) at the cost of a little accuracy (errors in parsing citations or authorship) and with an austere approach (few indicators, and little user interaction). Nonetheless, it offers the most advanced management system for versions and duplicates.
Regarding ResearchGate, the great amount of documents already uploaded by a growing user base (especially from the biomedicine community) supports the usefulness of some of its indicators (especially Views and Downloads, now combined into Reads). However, the lack of transparency compromises its reliability. Likewise, unannounced changes in some of its key features make this platform unpredictable at the moment."....

They are different. ResearchGate depends on the available research papers in its database and the consent of the ResearchGate members to count the number of citations. On the other hand Google scholar engine searches its database for existing literature and references to count citations.
Google Scholar and ResearchGate citations are independent because they are based on their own database and data extraction method. Both are not free from errors, for example, wrong citations and duplicate citations.
I agree with the difference point as it was described by all colleagues, especially Mr. Boukarta description. Scholars can use RG database to increase the GS citation number since the search engine also read the RG database
Dear Dr. Raheam A Mansor Al-Saphory , YES YES the total citation in google scholar and Research Gate are different. In research gate, the total citations are counted if and only if the articles are uploaded in Research gate. For this reason, the total citations are limited to the RG platform only and total citations are most likely less than that of google scholar which has the vast coverage over the Research gate.
There is a problem in ResearchGate citation. Since it depends only on its database what guarantees that the uploaded research papers have been really published? What if this literature have been uploaded with many false citations? In contrary, Google Scholar search all the databases that can be reached by its search engine. It search IEEE xplorer, Springer, Elsevier, Scopus...etc. This gives more credibility to Google scholar.
The real issue is which one is more important. For example if you apply for a Professorial Position in a first rate school in USA and you have 1000 citations from Research Gate and your opponent has 850 from Google scholar and everything else is equal which one will be chosen.
Is there a difference between the h index between research gate and google Scholar and if yes which one is more important
Why famous Universities do not recognize nor accept the RG citations and the h index with the same seriousness as the Google scholar h index . Something has to be done.
If the scientific community is not capable to stand up against the google supremacy on destroying academic career there is no hope to change anything .
ResearchGate database depends on papers people have uploaded, Google scholar depends on checking bibliographic databases and publishers. However one can add own papers which have not been found by Google Scholar manually. Papers that cite one's publication, but are missing in google scholar, however, are difficult to add.
