In some contexts, the term SEM is used exclusively to mean pay per click advertising, particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
At the retail level, the two top organic food sales categories, receive significant price premiums over conventionally grown products. ERS also analyzed organic prices for 18 fruits and 19 vegetables using 2005 data on produce purchases, and found that the organic premium as a share of the corresponding conventional price was less than 30 percent for over two-thirds of the items. The premium for only one item—blueberries—exceeded 100 percent. In contrast, in 2006, organic price premiums for a half-gallon container of milk ranged from 60 percent for private-label organic milk above branded conventional milk to 109 percent for branded organic milk above private-label conventional milk.

New zero-result SERPs. We absolutely saw those for the first time. Google rolled them back after rolling them out. But, for example, if you search for the time in London or a Lagavulin 16, Google was showing no results at all, just a little box with the time and then potentially some AdWords ads. So zero organic results, nothing for an SEO to even optimize for in there.
People use search engines to get more information about the products or services that they are interested in purchasing, as well as the businesses that they are interested in purchasing from. Consumers will turn to search engines before doing business with a large national company, and they will also utilize search engines when planning to make local purchases as well.
Creating the link between SEO and PPC represents an integral part of the SEM concept. Sometimes, especially when separate teams work on SEO and PPC and the efforts are not synced, positive results of aligning their strategies can be lost. The aim of both SEO and PPC is maximizing the visibility in search and thus, their actions to achieve it should be centrally coordinated. Both teams can benefit from setting shared goals and combined metrics, evaluating data together to determine future strategy or discuss which of the tools works better to get the traffic for selected keywords in the national and local search results. Thanks to this, the search visibility can be increased along with optimizing both conversions and costs.
Organic is different. Matching keywords to user intent means you may be present in many searches. The user may find you consistently, and once they get to your site, they are more likely to stay. Organic users are still your best long-term customers. In my experience, they have lower bounce rates and more pages visited, and they are more likely to return.
