Search Engine Marketing

So how many search engines do I need to target in my marketing? Search engine marketing, or SEM. Well that depends. Some engines have language versions. In some industries there are specialty engines. In general there are maybe ten that need to be addressed and of that Google, Yahoo and MSN Live will account for over 80% of your traffic.

Search Engine Submission

Search engine submission is the registration of your site at the targeted search engines. It is monitoring the progress of submission as it may have to be initiated again.

There are tools and services that claim to submit your site to hundreds of engines; that is a nice marketing ploy but you only need to worry about the top 10. Additionally, there are a few that have to be done manually.

Submission does not guarantee inclusion to any engine. Some search engines may have a charge associated with them.
