The webpage at https://dnb.com/pl-pl/marketing/zdobadz-nowych-klientow.html might be temporarily down or it may have moved permanently to a new web address.
Biggest issue: It's not even online. How can anyone reach potential leads if they can't even load the page? Without access to any content, imagery, structure, or design, you're essentially losing out on every potential customer. A website that's inaccessible or non-existent gives off an impression of unprofessionalism and can severely damage credibility. You might as well hang a "Closed" sign on your digital storefront.
