The ABCs of SEM

Share with:

Search engine marketing (SEM), like many other fields, is full of acronyms. Those of us that are veterans assume everybody knows what we mean by “the ROI of PPC” and similar statements. If you’re new to SEM, though, you’re probably lost in the alphabet soup. So, I’ve attempted to post a list of common acronyms here.

DTC: Direct Traffic Center (Yahoo’s old pay-per-click user interface)

G: Google

GYM: Google / Yahoo / MSN

PPA: pay per action

PPC: pay per click

QS: Quality Score

ROI: return on investment

SE: search engine

SEL: Search Engine Land

SERP: search engine results page

SES: Search Engine Strategies

SEW: Search Engine Watch

SMX: Search Marketing Expo
