Since 2003, internetVista has been continuously monitoring your website and Internet services by simulating a visit or a user path from a customer and prospect perspective.

Simulate, monitor and optimise your visitors' path through your website by putting your key pages under monitoring (contact form, purchase process, login, api, etc.). An inaccessible server or a website that does not respond can cost you a lot of money. It can not only damage your image but also generate losses. These unavailabilities mean reduced traffic, leads or sales in the case of e-commerce. Whether it's a quotation request on your website, a contact form or an e-commerce transaction, nothing is more frustrating for a visitor than being faced with a form or a page that doesn't work or that is loading slow. And for the company, this means a guaranteed loss of income. -
