Buying expired domains can get you valuable visitors and an already strong standing in search engines and website directories. However if you pick the wrong domain you can lose traffic, popularity and reputation.

Search Engine Bans

Everyone hates those sites that occupy domains and have sites with one a homepage covered in Spam and paid for search listings links. And so search engines have various methods to counter the Spam pages with spoil results and annoy searchers.

One system that many search engines use, including Google, is to permanently ban Spam addresses. The ban can be appealed but this takes time and effort, which you really don't want to be wasting. The key is to find out before you buy.

Research the owner

Does the previous owner, own one domain or one hundred domains? If they own loads of domains, the chances are that they will all be part of an interconnected Spam network set up to fool search engine spiders and generally annoy people.
