Ppc terminology

PPC Terminology

  • PPC: Pay Per Click

  • CTR: Click Through Rate

    • Percentage of clicks to impressions

  • CPC: Cost Per Click

    • Price an advertiser pays for each click on his/her ad

  • Daily Budget

    • Amount advertiser is willing to spend, each day, on PPC ads


How ppc works

How PPC Works

Advertiser

User enters query

Advertiser s place bids

Engine runs auction and displays winning ads

Advertiser’s Website/Landing Page

Surfer “lands” on website

User

Surfer clicks on an ad

Search Engine Server

Millions of auctions executed every day

Once the daily budget is reached, the ad will no longer be shown.


The ppc auction model

The PPC Auction Model

  • Basic model

    • Highest bidder gets highest slot

    • Winner pays winning bid

    • Not ideal! Why?

  • Vickrey-Clarke-Groves (VCG) auction

    • Second price auction

    • Optimal for single slot

    • Reveals true willingness to pay, no need to be strategic

    • Winner for slot i pays maximum bid of bidder that get i+1 slot

  • Still not the best for Google, Yahoo, MSN etc.

    • Why?


Ad quality score landing page quality

Ad Quality Score + Landing Page Quality

  • Search engine needs repeat customers

  • Needs to improve user experience for long term

  • Bid transformation:

    • (Bid $ amount) x (Ad Quality Score)

      ~ (Bid $ amount) x (CTR rate + relevance)

      In other words, rank by expected revenue for Google

  • High quality ads → Lower bid amount(incentive compatibility)

Main difference between Yahoo and Google until 2007

Mini case cost per click and holidays

Mini Case: Cost per Click and Holidays

  • CPC increases before the holidays

    • Should advertisers refrain from bidding?

  • How to approach the problem?

  • CPC increases but conversion rate (CR) increases more

  • Cost per Acquisition (=CPC/CR) drops!

  • Holiday season offers better bargain than other days

Improving ppc roi the long tail concept

Improving PPC ROIThe “Long Tail” Concept

  • “The Long Tail” by Chris Anderson

    • An aggregate of less popular products can sell more in the “long tail” than the most popular products

  • Same applies to PPC

    • An aggregate of specific, less searched terms can provide better ROI than highly searched terms

Does it really work yes

Does It Really Work? YES.

  • Major athletic retailer case study

    • 80% of PPC sales come from long tail keywords

    • Specific, product-name keywords

    • Only 20% of sales come from broad terms, like “BRAND shoes” or “BRAND jacket”

  • Most “long tail” keywords are inexpensive

    • [web hosting] $8.30

    • [freebsd web hosting] $0.10

  • Targeted at customers with specific needs, closer to purchase
