Site Validator has saved me at least 28 hours of work and has provided a much better look at the sites overall. Before it, I only used to validate 5 random pages by hand.
CEO at SkyToaster. Florida, USA
Gone are the days of manually validating individual pages or relying on browser add-ons to validate the pages you view. Site Validator makes site validation quick and precise. It is well worth every penny.
Studio Manager at ISSL. Lancashire, UK
ISSL has a small team of Web Designers, but we create a large number of high-quality websites. Validating each of the pages on these sites was taking up a large portion of the final stint of a project. After discovering Site Validator, it paid for itself on the first website we tested - even finding and validating automated pages we usually don't consider. Not only does Site Validator save us time and money, it helps find errors we might not have normally found.
Director at All Advertising. Essex, UK
Site Validator made an easier task to validate a whole site, they are open to suggestions and are developing a very helpful tool. We will be using this site for all our validation needs, GREAT JOB!
