our site was noticed by google because of having so many unnatural links. so we deleted as many as we could then submit our site for reconsideration. however, google didn't remove the penalty because there are still many artificial links we couldn't delete. As a result, we have a very poor ranking nowadays. we rarely get a new sale. We are planning to buy a new domain for the same company. we will change everything(design,content) except company name, logo and contact information.We will not remove the old domain because we still get traffic. Do you think if it would be a good idea to have 2 domains for the same company ?Would it be a risk of getting penalized by google again because of having multiple domains for same company?
From my understanding, google will not penalize for having 2 domains from the same company. Many companies have more domains on them, for whatever purpose they have. Also, that's a good idea to change the content to avoid duplicate. For 301, DO NOT/ NEVER do it because it will also pass the penalty to the new site.
i must create a fresh content for my new domain. do i have to create a new design too ? or can i use my old design for the new domain ? do you think google would consider my html codes as content so flag my new site as duplicate content because i would have 2 different domains with same design?
You should be fine using the same design. Just think of all the same Wordpress Templates with the same coding people use without getting penalized. If you must create a new site, you WILL want to create unique content for that site, otherwise Google will see that at duplicate content, and you will be penalized again.
I will create unique content for each. but what about having same company names in different domains ? woudn't it create a negative impact to the ranking ?assume that i have abc.com and def.com. my both sites have same contact information and same company name in the title.would it affect both sites' ranking badly ?
