SEM for people selling things is easy, but what if you are using SEM to get your website a kick start? SEM for bloggers and content producers can be difficult and has to be used in moderation, but it can have a big impact if done correctly.
Setting up an adwords, adcenter, or other online campaign takes thought, planning, and constant revision.
SEM involves the promotion of websites by increasing visibility in search engine results pages. This happens through paid placements, context advertising, and paid inclusions.
