英文摘要：

[Objective] Search engine optimization is an important way to enhance the core competitiveness for digital library. It can help digital library provides high density information and better digital resource services for users. [Methods]Based on the perspective of information ecology,this paper uses analytic hierarchy process to construct search engine optimization index in digital library. [Results] Through the empirical analysis of 10 typical digital library websites at home and abroad,the paper proves that the constructed assessment index has a strong operational and practical value. [Conclusions] The paper aims to provide new perspectives on the theoretical level for the construction of digital library website,and to guide the digital library website for a better ecological construction by using search engine optimization based on the application level.
