Zeeff recommended that when Web site owners shop for a CDS, they consider transparency, log files and the strengths and weaknesses of providers. All of the content delivery services are transparent to users. Users can enter a URL in their browser, link to a site and bookmark that site with CDS just as they could without the enhanced service. But CDS should be transparent to the Webmaster as well. Ideally a Webmaster should not have to make any changes to its site's pages.
Some services require changes to all of the image links on a site's pages.
In this instance, the name of the CDS provider is displayed at the bottom of the browser screen as images are loaded, possibly diluting the site's marketing message. It is not necessary to accept this inconvenience, which also impedes a site's ability to switch to a new CDS provider quickly if needed. Zeeff also advised that companies investigate the procedures needed when content is updated. Typically, the CDS needs some kind of notification when you change content on your site so the copies of your pages are re-updated and the cached versions are always correct. Another issue is maintaining accurate log files.
