The mother of my girlfriend has a contract with a company that provides her website and domain. The contract costs 360€ per year and it expires on May 1st. The website and domain will be probably taken down by that date. She doesn't want to renew the contract because the company doesn't fulfill her change wishes and because it's to expensive in her eyes.
The company owns the website including the domain. She has the copyright rights on the texts of the website. The company offers to sell her the domain for 180€, she doesn't want to pay that.
Our priority is to keep the Google ranking. Will she lose it when we create a new website with the same text content on a new domain without redirecting the old domain to the new domain? (The company probably won't be willing to redirect.)
I know that Google has a penalty for duplicate content, but what will happen when we go online after the old domain disappears? What are our options?
