Originally created in 2004, Google Scholar provides access to journal articles, academic books, book chapters, and non-peer-reviewed materials. Google Scholar citation counts have been used in hiring and tenure decisions as a criterion of evaluation, and citation counts have increasingly been used to provide rankings of individual faculty in terms of their citation counts relative to others in their cohort or field (Kim and Grofman Reference Kim and Grofman2019; cf. Masuoka, Grofman, and Feld Reference Masuoka, Grofman and Feld2007) and in ranking departments in terms of the total or mean citation counts of their faculty (Peress Reference Peress2018). However, as discussed in Chwe et al. (Reference Chwe, Htun, Jensenius, Lawrence, Samuels and Singer2017), and even more vociferously in online web postings, the use of citation counts for these purposes remains controversial. One issue concerns the degree to which Google Scholar coverage has defects (Samuels Reference Samuels2011; Reference Samuels2013), but the greatest controversy is about the use of citation counts as a metric for evaluating scholarly performance. We do not take a position regarding that controversy. Rather, we simply note the undisputed fact that because it is so easily accessed and so apparently comprehensive, Google Scholar has become the app of choice to quickly trace work on particular topics or to locate a scholar’s publications, including books.
Access to authors’ work is facilitated if they create a Google Scholar profile. To create a profile, a scholar first provides basic biographic information and then relevant publications. In addition to showing citations to each identified work, a scholar’s total citation count is automatically tabulated by the app. Scholars who want to increase exposure to their work have an incentive to create this profile.
Many scholars use Google Scholar profiles to find information but less than 45% have their own profile. The goal of this study is to identify characteristics of those scholars who have chosen to create a personal Google Scholar profile. To do the necessary matching of profiles and demographic, academic-rank, and field-of-interest information about profile creators, we limited the search to tenured and tenure-track faculty with full-time appointments in PhD-granting political science departments. We then could take advantage of the data collected by Kim and Grofman (Reference Kim and Grofman2019) for this set of scholars because it already contains the necessary information. Even among this restricted set of political scientists—who presumably have a strong incentive to create a Google Scholar profile because they are at research-oriented universities—only 43.7% created one (i.e., 1,654 who did versus 2,128 who did not).Footnote 1

This article examines how the creation of Google Scholar profiles for the faculty in the Kim and Grofman (KG) dataset is affected by rank and date of PhD, subfield, gender, and citation count. Using this dataset, we might expect that older faculty are less likely than younger faculty to have a Google Scholar profile; highly cited faculty more likely than less-cited faculty; women less likely than men; or possible differences by subfield. We examine these expectations and discuss the implications of our findings.
First, we assess this question by rank (figure 1). There are no strong differences across faculty ranks in the likelihood of having a Google Scholar profile, with the exception of emeriti, of whom only 10% have profiles. However, although the differences are not as significant as we might have expected, younger faculty are more likely to have a Google Scholar profile than those in higher ranks: more than 55% of assistant professors maintain a profile.
However, figure 1 may be misleading in that the ranks of full and associate professors show considerable variability in the date of the PhD of faculty in those ranks. Figure 2 shows the same type of data as in figure 1 but by five-year cohorts.Footnote 2
Figure 2 shows that those in more recent cohorts are much more likely to have a Google Scholar profile than those in older cohorts. More than half of those in the cohorts from 1995 to 2014 have a Google Scholar profile, whereas less than 10% of the still-teaching faculty with a PhD from 1950 to 1969 have a profile, and the pattern is near monotonic. We do not expect the one exception to monotonicity in this graph (i.e., the most recent cohort) to be lasting because we assume that some of those with very recent PhDs will create a Google Scholar profile when they have more publications and receive more citations.
Table 1 shows the same type of data as in figures 1 and 2 but by principal subfield.Footnote 3
Notes: PP=public policy; PA=public administration; PL=public law; and PP=political psychology.
Table 1 shows that between 43% and 55% of those in each subfield have a Google Scholar profile, with the notable exception of theory, which is only 24%.
Figure 3 shows the same type of data as in figures 1 and 2 but by gender.
The figure shows that there is no substantively meaningful difference between female and male scholars in the likelihood of creating a Google Scholar profile and that female scholars are slightly more likely to have one.Footnote 4
Figure 4 shows the same type of data as in figures 1, 2, and 3 but distinguishes among faculty by their citation count relative to others in their cohort. That is, for each cohort, the figure compares the proportion of those who have a Google Scholar profile among those in the top 25 of the cohort in terms of number of citations with those in the bottom 25 of the cohort regarding citations.Footnote 5
We expect that, controlling for cohort effects, more-cited scholars are more likely to have a Google Scholar profile than less-cited scholars. Figure 4 demonstrates this because those in the top 25 of each cohort are much more likely to have a profile than those in the bottom 25. Although the ratio of the two percentages is greatest for some of the older cohorts, more than 95% in the top 25 of the 2000–2014 cohort maintain a profile. We expect that the proportion with a profile will increase among the most-cited scholars in the most recent cohort as they become more professionally involved.
SUMMARY OF RESULTS
The figures and table show that when looking at those who have a Google Scholar profile and those who do not, among the set of those in the Kim and Grofman (Reference Kim and Grofman2019) dataset and contrary to our initial expectation, there are no real differences by gender.Footnote 6 Similarly, there are few differences by subfield, with the notable exception of the low proportion of theory faculty who have a profile and the fact that having a profile is slightly more common among those who self-label as methodologists. However, as expected, with the exception of those recently starting in the discipline, younger cohorts are more likely to have a Google Scholar profile than older cohorts. Moreover, figure 4 shows that those who are highly cited relative to others in their cohort are more likely to have a profile than those who have fewer citation counts.

WHAT DO THE GOOGLE SCHOLAR PROFILE DATA IMPLY?
The Google Scholar profile data show that junior and early-career faculty are more likely to have a profile, political theorists are less likely to have a profile, and those with higher citation counts are more likely to have a profile.
Junior and Early-Career Faculty Are More Likely to Have a Google Scholar Profile
As Jensenius et al. (Reference Jensenius, Htun, Samuels, Singer, Lawrence and Chwe2018) pointed out, Google Scholar often is used to evaluate faculty for tenure and promotion as well as scholarly impact. Our results show that junior and early-career scholars are significantly more likely to have a profile than those who have been in the field for a longer period. Although our data do not allow us to address issues of causation, one likely cause of the disparity is simply the level of familiarity with the Internet and Google Scholar. Older faculty grew up in an era when citations were counted on the Web of Science and, ceteris paribus, are less likely to be tech savvy and/or may have less interest in maintaining an online presence. Also, whereas most “academics are under never-ending pressure to ‘publish or perish’” (Jensenius et al. Reference Jensenius, Htun, Samuels, Singer, Lawrence and Chwe2018, 821), this is especially the case for junior scholars who are working toward tenure and promotion. Moreover, whereas obtaining tenure or promotion to full professor rank has always been a difficult process, the experiences of the older of our two authors suggest that the pressure to publish has increased substantially in recent decades. Of course, greater familiarity with web and social media–based forms of communication often results in recognizing the desirability of taking advantage of these platforms—and perhaps fear of the consequences for failing to do so.
Political Theorists Are Less Likely to Have a Google Scholar Profile
According to our results, about 50% of faculty in various subfields were likely to have a Google Scholar profile. The main exception, however, was in political theory, in which only 25% had a profile. It is not especially surprising that the most quantitatively oriented political scientists—the methodologists—are most likely to have a Google Scholar profile. However, we also suspect that political theorists have the least need for a profile because they are more book oriented in terms of publications, and Google Scholar is most useful for tracking and publicizing journal articles. Theorists may have fewer items to include in a Google Scholar profile that would need to be identified by those interested in reading their most important work; thus, they have less need for a profile.Footnote 7
Those with Higher Citation Counts Are More Likely to Have a Google Scholar Profile
In almost all cohorts, those with higher citation counts are much more likely to have a Google Scholar profile. This also is an expected pattern in that, like younger and early-career faculty, those with higher citation counts may find it more desirable to gain recognition by taking advantage of platforms such as Google Scholar. A profile lists scholars’ works along with their citation counts; the more someone has published, the more reason to showcase accomplishments and allow others to more easily find (and download) the work. Of course, there are other ways to display citation counts; some scholars list them on their CVs (Jensenius et al. Reference Jensenius, Htun, Samuels, Singer, Lawrence and Chwe2018) or their website. However, Google Scholar does not require manual input like these alternatives. Instead, it automatically tracks a scholar’s citation counts in a clear and easily accessible way and makes them available to a broader audience—which is incentive for those with higher citation counts to create a profile.
CONCLUDING REMARKS
We believe that our results from this study can contribute useful factual information to an ongoing debate about how to evaluate—from a more normative perspective—the increased importance of self-promotion and an online presence in the academy.
Until recently, the Social Sciences Citation Index and Web of Science were the most widely used references for research productivity. Yet, Google Scholar has risen to prominence as a measure that is transparent, easily accessible, and a relatively simple platform.
Until recently, the Social Sciences Citation Index and Web of Science were the most widely used references for research productivity. Yet, Google Scholar has risen to prominence as a measure that is transparent, easily accessible, and a relatively simple platform. Moreover, it comprehensively compiles articles, books, and manuscripts (Peress Reference Peress2018). Although it has limitations and should be used with caution (Jensenius et al. Reference Jensenius, Htun, Samuels, Singer, Lawrence and Chwe2018), it is currently the most prominent platform that allows scholars and academics to share and access information. It is much easier to identify and download the work of scholars who have a Google Scholar profile. It saves those interested in the work of an author from scrolling through numerous article and paper titles by authors with a similar name in multiple disciplines to identify the particular work or to review a CV and then search elsewhere for downloadable versions of the work.
The presence or absence of a Google Scholar profile does not affect the ability of those reviewing tenure and promotions to identify publications because CVs have been submitted. Neither should it affect the weight given publication counts or evaluations of the prestige of journals and books in which articles and chapters appear. Whether the presence or absence of a Google Scholar profile affects the incentives of those making tenure decisions to weigh citations more heavily is less clear because it does facilitate the gathering of citation information. Conversely, the presence or absence of a profile may affect how visible a scholar is in the field when soliciting external reviews. Thus, we believe that on balance, it is desirable for scholars to create a Google Scholar profile for visibility purposes. We particularly encourage younger scholars and those beginning to build a publication record to create a profile. However, we also emphasize that reliance on citation counts is particularly pernicious in the evaluation of junior scholars whose work has not yet had time to be visible to and impact the broader scholarly community.
