How do online-ads companies make $
Companies like Yahoo! that serve out ads into your browser window get paid by the client companies featured in those ads
How is online advertising paid for? Cost per click (CPC), or Cost per thousand impressions (CPM), or Affiliate programs (typically, % of consumer’s purchase on
the linked-to site) Negotiated price for fixed time period
E.g., I’ll pay you $2,000 per week for having my company’s banner ad at the top of your website home page

How important is the online ads market?
Google’s market cap is greater than that of…
… News Corp which includes Fox, MySpace, and the Wall Street Journal,
… Disney includes ABC, ESPN, theme parks, and Pixar,
… Time Warner includes Fortune, Time, Sports Illustrated, CNN, and Warner Bros.,
… Viacom (MTV, VH1, and Nickelodeon),
… CBS,
… and the New York Times — combined!

ORGANIC
PAID
Paid vs. Organic (natural) search
![Page 9: Online search and ads](https://reader035.vdocuments.us/reader035/viewer/2022062501/5681685f550346895ddea668/html5/thumbnails/9.jpg)
Where organic results come from?
Will your new blog or personal page show up in Google’s organic search results?
Google’s indexes content of over one trillion URLs Uses “software robots / spiders / Web crawlers” (i.e.,
software) to sporadically traverse links on the WWW Depending on the time/day of the last spider visit, Google’s
index of a page can differ from the current page You can sometimes pull up the old page by clicking on a
“show Cached page” link in Google
To have your page *not* be indexed, put this in <head><META NAME=“ROBOTS” CONTENT=“NOINDEX, NOFOLLOW,
NOARCHIVE”>

Order of organic search results from http://www.google.com/technology/index.html
: “PR [Page Rank] relies on the uniquely democratic nature
of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B…. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."

Aside: Google intranet search Your organization can set up an internal Google search
page behind its firewall that indexes the pages on the company’s intranet …requires purchase of Google’s “Search Appliance”
This may be extremely useful, as Google.com’s organic index spans only public WWW pages Private pages (such as your Facebook page and other
pages that are password-protected) cannot be crawled to by the search spiders

Paid search ads Google (Facebook too) constantly runs auctions to
determine who is the current highest-bidder for paid search ads
Much like “PageRank” for organic search results, sponsored links are ordered according to their: Ad Rank = Maximum CPC × Quality Score
The “Quality Score” for a sponsored link depends on: How closely the ad seller’s keywords match the user’s
search keywords How good the page is that the sponsored link points to The prior CTR (click-through rate) performance of that
sponsored link

For advertisers: Google AdWords paid search ads

CPC rates can be expensive!

Google AdSense: small Google served ads on your site, not in Google searches

Online ads POA
Market overview Google search ads
Page Rank vs. Ad Rank Google AdWords ads
Google AdSense ads Fraud types Customer profiling

Why are firms willing to pay high CPC rates?
Ads can be: Keyword targeted User’s system targeted (e.g., Apple vs.
Windows) Geo-targeted
Example: IBM has used IP targeting to tailor its college recruiting banner ads to specific schools, “There Is Life After Boston College, Click Here to See
Why.” …CTR was around 15%, vs. the typical <1%

Customer profiling: Cookies A web-server can store information about your
interaction with it’s website and ask your web-browser (e.g., Firefox) to store that information in a text file on your computer’s hard-disk
That way, when you return to the site, the site recognizes you (e.g., your username, site history, even password)
Normally, a web-server is specific to a particular site, e.g., REI.com, so the web-server’s “REI cookie profile” about you only can know about what you did at REI.com
![Page 21: Online search and ads](https://reader035.vdocuments.us/reader035/viewer/2022062501/5681685f550346895ddea668/html5/thumbnails/21.jpg)
Tracking cookies BUT, what if the same web-server handled all
the websites you visit? The Google AdSense network ads appear on many
sites you visit Each of those ads is actually served to you by
Google That means Google can potentially use a
“Google cookie” to store your history of clicking across many sites you site The objective: to “figure you out” as a customer type

Tracking cookies Before 2009, Google hadn’t used tracking cookies
on its AdSense network. After 2009, Google started
Google’s Ads Preferences Manager (you can “Google this”) will show you the the profile its tracking cookie has enabled Google to infer about you
Google also allows you to install a cookie and/or browser plug-in that opts you out of interest-based tracking.
