Spamming Google Scholar. Very possible, or so it seems…
“…we conducted several tests on Google Scholar. The results show that academic search engine spam is indeed – and with little effort – possible: We increased rankings of academic articles on Google Scholar by manipulating their citation counts; Google Scholar indexed invisible text we added to some articles, making papers appear for keyword searches the articles were not relevant for; Google Scholar indexed some nonsensical articles we randomly created with the paper generator SciGen; and Google Scholar linked to manipulated versions of research papers that contained a Viagra advertisement.”
