I am putting together new content for a new site. I have a domain from 2001 that hovers in the 50s. I am thinking about pulling the copy, etc. from the old site and plugging the new one in. However, is there still a sandbox to deal with if I go that route? Or should I start on a fresh domain? I wanted to utilize the old domain...its got some decent links and obviously age on its side. Thoughts?
The sandbox has evolved. Google looks for quality signals and if your site can generate it then you will be fine. Most new sites are not able to generate these signals fast enough so they tend to not rank well until these signals are developed over time.
If your old site did not rank well why re-use the content? Ask yourself what value your content provides that is not available on any other website. If you can;t come up with several items of value then you probably want to think about revamping the content. Good luck.
