My google scholar citations are more than double what RG shows but I prefer RG because it connects me with scholars in all areas.

Yes, I have observed changes in my citation no. On GS. But it is not all inclusive. My total citation count as shown on GS is 430 whereas on RG, it is 441. Non of the two however are comprehensive.

Actually, my numbers are worse than those reported by many of the respondent! My RG citations is 252 while my GS citations is 543. I know many citations are missing from both!

Actually what I noticed in GS about one my article, once it has 107 citations some month before, but now that article has 104 citations. I am wondering how other citations disappeared. On the other hand during this period, some more citations also increased recently.

Generally you will have more citations from GS than RG. In my view RG takes in to account latest publications only or Articles from RG.

Yes, it does happens. Google scholar account for all your citations that appear on google, meaning whenever an article cite your work properly and that article appears on google, the citation will be recorded for you immediately. On the other hand, Reseachgate accounts for all your citations that appear on researchgates, meaning whenever an article cite your work properly and that article is documented on researchgate, the citation will be recorded for you immediately.

@Dr. Tripathi: The usual occurrence is the case of GS citation higher than the RG, which is because GS automatically picks all your citation that are properly done, while RG only accounts for citations from articles documented on RG. Your GS citation is less than that of RG probably because most of the articles that cite your works did not cite them properly.

@ Dr Peter Alaba,

My question was actually related with GS Citation.

@ Dr. Chalise, your citation for that article reduced from 107 to 104 probably bacause some of the citations were added twice due to duplicate version of some articles on GS (the duplicates are mostly HTML version). Once the duplicates were detected by GS algorithm, the citation will be normalized (in your case, from 107 to 104).

@ Peter Alaba, Thank you for the logical response.

I asked similar question two months ago and got an the following answer by Piotr T. Nowakowski: "It happened sometimes also to me. I suspect that somebody (author? publisher?) could remove the PDF copy of the paper from the repository on the Internet. This is why GS may not see it any more."

I frequently feel this changes in Google Scholar. Yes, the actual reason may be given by Jamal Kaid Mohammed Ali .

You can change the articles in your profile, but citations to them are updated automatically as we update Google Scholar.

Most of the time , it shows useless citation records

It happened to me recently and I discovered that the citations were "cleaned up". They removed double recorded citations. I have mo idea how does it come to double citation.
