Hi,

Maybe the reason is that Google Scholar draws material only from academic sites, and the Google search draws material from any site ? 

Maybe that venue is not indexed or abstracted by google scholar ... 

Hi Dear Mohammad!

Please visit home page of journal which published your article. Usually in a box such as "About us" you can find Indexing Information.

This is true to several other scholars like you. The google scholar cites those papers that are published in recognised and popular journals and possibly with high impact factor. The papers which are published in local journal or not popular or standard journal will not find mention under google scholar.

Thank you all. What if the article is published in impact factor journal but still not appearing in google scholar. I tried to upload the full text on "researchgate" and "academia" type of portals so that it can appear in google scholar but no use. Probably, the publisher has not listed/indexed the journal with google scholar.

Hi,

if the paper is very new (published in 2017), it could be that it is "not yet" published in GS. Probably you could see in on GS in the coming months. 

whenever article is published first it appears in Google Scholar  after  some time it appaears in GS.
