In Google Scholar, the article citation count is displayed on every article.
Google Scholar Citations allows you to create a profile to keep track of your publications indexed in Google Scholar and the number of citations they have received. It also provides metrics including h-index.
The "Get Started" box at the bottom of the Google Scholar Citations page will walk you through creating your profile. The tabs on the left of that page provide more information about the process.
You may choose whether your profile will be public or private. If you choose public, people will be able to see your profile and citation information by using Google Scholar Citations search. A public profile will make it easier for other researchers to find you and will help to promote your work. You can also link your Google Scholar Citations profile to your ORCiD (find more information under author disambiguation on the left side of this guide). Here is an example of a public profile:
You will be able to see the h-index of any author who has a public Google Scholar profile. Google Scholar does not allow for finding impact scores for authors without public profiles, groups of authors, or institutions. However, a free downloadable software called Publish or Perish can help with analysis of Google Scholar data.
