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.
