Background Server certificates increase security on the internet and are used to verify websites. A certificate is issued and verified by an official, trustworthy institution and verifies the identity of the website. A certificate cannot be forged. In everyday life, a certificate can be compared to an identity card or a notarized document. Similar to a passport, certificates are also valid for a certain period of time. Thus certificates make it possible to exchange data via secure connections and form an important basis of trust for operators of online shops.
Consequence In the standard settings, most Internet browser are configured so that websites with an expired certificate are not trusted. A website with an expired certificate will generate a warning message whenever it is accessed. Some browser or plug-ins, depending on their configuration settings, can block access your website completely. If visitors to your website receive a warning message, this will have a negative effect on your company's presentation on the internet. If internet browser do not trust your website, why should your customers trust you? An expired SSL certificate will also have a negative effect on search engine rank. Your company may no longer be listed at the top of a search engine results page, and it may move down the page even further if the problem persists. Visitors may even be alerted in the search results that there is a security issue on your website.
