Abstract
This study examined ten prominent global repositories through comprehensive webometric analysis. MOZ software, a link analysis tool, served as the primary analytical tool for measuring various performance metrics, including Domain Authority (DA) and Page Authority (PA) scores, along with comprehensive link analysis covering inbound and outbound connections, internal and external link equity distribution, linking domain counts and newly identified link discoveries. To determine the web presence of each repository, the Google search engine’s site-specific operator was used to extract total webpage counts. Network visualization techniques mapped repository interconnections, while a nineteen-point evaluation framework was used to assess functionality and characteristics of the repositories. Webometric analysis measured web page counts, link structures and Web Impact Factors to evaluate online performance. Results show the Astrophysics Data System (ADS) and NASA Technical Reports Server (NTRS) achieved the highest Domain Authority scores and linking domain counts, demonstrating superior credibility and web presence. The eScholarship Repository (ESR) achieved exceptional performance, with a Simple Web Impact Factor of 179.28 and an Internal Link Web Impact Factor of 177.24, exhibiting a strong overall link equity distribution. Link analysis revealed significant differences in web visibility and stability across repositories. Content evaluation revealed widespread deficiencies in user support features, including the absence of grants and fellowships, awards, customer service details, frequently asked questions (FAQ) sections, blogs and update notifications. These results offer practical guidance for enhancing repository design and functionality, helping repository administrators, researchers and academic institutions improve their digital presence and user experience.
