How are SEO SEM and PPC different from each other?

SEM and PPC are other common words you want to meet in search marketing. Understanding these distinctions helps to clarify what SEO is – and what it is not.

Seo vs beans

SEM means search engine marketing, which is an umbrella word for activities that involve organic and paid search.

Technically, SEO is part of SEM:

• SEO: Driving organic search results, clicking from the search engine.
• SEM: Driving click from organic and paid search results.
• PPC: The paid search result clicks from running search engines (eg, Google advertising).

A useful way to imagine it: Sem is like a coin. SEO is one side, which represents organic traffic. PPC is the flip page, which represents the paid traffic.

 

SEO vs. PPC

PPC means pay-per-click, a type of digital marketing where advertisers are charged when someone clicks on his ads.

Advertisers offer specific keywords or expressions that they want advertising search engine. When a user searches for one of these keywords, the advertiser’s paid entry between top results is displayed.

Think about search marketing as a coin: SEO and PPC are two sides of the same coin.

With PPC, the advertiser pays when a search user clicks on his payment list, he pays.

With SEO, the search results are not paid directly to the listing. However, SEO requires investment in services, material production and optimization of websites, so organic discovery is not really “free”.

Many violent SEO -er vs. PPC claims, ask which channel provides better ROI. The truth is that they are supplementary digital marketing channels. Ideally, both should be used if your budget allows.
