PPC - Pay Per Click
CTA - Call to action, e.g. sign up, follow us, buy now, order now
CPC - Cost Per Click, which is the amount of money spent to get an ad clicked when running paid search marketing campaigns.
CTR - Click Through Rate, expressed as a percentage, is the number of clicks your ad receives divided by the number of times your ad is shown.
CPM - Cost per Mille (mille meaning thousand) is the cost every time your ad receives 1000 impressions.
SERPs - Search Engine Results Pages are web pages served to search users when they search for something online using a search engine like Google or Bing.
SEM - Search engine marketing, which used to be an umbrella term for both search engine optimization and PPC advertising. Now it's more commonly used to refer to paid search marketing.
