How to Test Your SEO With Rigor

By acting as a middleman between the Web server and the spider, proxy servers can facilitate useful tests that normally would be quite invasive on the e-commerce platform and time-intensive for the IT team to implement.

Comparison Testing

During the proxying process, not only can words be replaced, but also HTML, site navigation, Flash, JavaScript, frames, even HTTP headers — almost anything. It also can give you the ability to do some worthwhile side-by-side comparison tests, a champion/challenger sort of model that compares the proxy site to the native Web site.
