My client's previous SEO team used link farming to increase the rank of the old domain. Due to this, the site was penalized by Google.
When we took over, the old domain seemed completely un-indexed; the site wasn't returned in any searches whatsoever.
In response, we created a site at a new domain; this new site is indexed and searchable, but still has years of previous SEO to make up.
Recently, however, the old domain became searchable again somehow.
- Is it safe to upload the new site at the old domain?
- How can I ensure that the link farm links don't point to the old domain anymore?
- How can I ensure that the old site's penalty won't affect the site in the future?
