Generally, Search Marketing includes Search Engine Marketing (SEM) and Search Engine Optimization (SEO), both solutions are trying to enhance visibility by ranking your website in higher Search Engine Results Pages (SERPs), so as to drive website traffic.
They sound similar, how to distinguish SEM and SEO? You have to understand the basic definition first.
Search Engine Marketing (SEM)

SEM is referring to paid advertisements, advertisers will pay a search engine to show their ad, hence having the opportunity to put promotional messages/websites in front of motivated customers who are highly intents to buy.
Advertisers will bid on high potential keywords based on customer behavior, that’s why search ad often known by the term “Pay-per-click ad”. There are a variety of search ad formats (i.e. Google Shopping Ads) and advanced features to enhance visibility and attractiveness (i.e. Price Extension, Auto Countdown).
Together with attractive/creative message (basically, we need “Title and Description, also known as T&D), we are able to encourage searchers to click your website or landing page for more details.
Search Engine Optimization (SEO)
SEO, is different from SEM because advertisers don’t pay for traffic or clicks, but pay for their own website optimization (sometimes SEO can be free, depending on the in-house talents and ways to optimize). We do SEO to rank websites higher in the given free spot of SERPs. In the free spot, we call the result “Organic Search Result” while the search ad is named “Paid Search Results”.
Compare with SEM, SEO request more IT skills because SEO performance is mostly related to the website performance, such as loading speed, image size and etc. Other than technical issues, we also need to do SEO content to enhance website relevance.
There are still other optimizations outside the website (we called Off-site SEO). Introduction to SEO (I)
