The invention relates to the technical field of internets, discloses a webpage data acquisition method, a browser client end and a CDN (content distribution network) server, and aims at solving the technical problem that a website structure needs to be changed in order to increase the webpage loading speed in the prior art. The method is applied to the browser client end and comprises the steps; initiating a page access request by the browser client end; acquiring a webpage source code corresponding to a page requested to be accessed from the CDN server according to the page access request, wherein the head of the webpage source code comprises a webpage element request script; acquiring HTML (hypertext markup language) static webpage elements in the page requested to be accessed from the CDN server side according to the script, wherein the quantity of the HTML static webpage elements corresponding to each subdomain server of the CDN server is smaller than a threshold value N which is a concurrent limit value of the same domain, and N is a positive integer. Therefore, under a condition that the website structure is not changed, the technical effect of increasing the webpage loading speed is achieved.
