As its name suggests, SEM or Search Engine Marketing refers to online marketing methods that seek to promote a company, brand,
product or service in search engine results. The 2 common methods are Search Engine Optimization (SEO) and Pay-per-Click (PPC) programs like Google Adwords and Yahoo! Search Marketing.
SEM has several key advantages over other online marketing methods:
Search engines like Google, Yahoo and Bing receive more than 100 billion searches a month. In Singapore, more than 220 million searches are conducted every month (refer to Singapore Internet Usage Statistics for more).
SEM offers targeting by keywords and geographic location, hence, displaying webpages and PPC ads that are related to what the user is searching for.
Because your webpages and ads are only shown for relevant searches, the conversion rate is higher since these visitors already have an interest in your products and services.
