How does PPC advertising
work?
The advertiser
• Creates advert copy
• Selects keywords for which the
advert should appear
• Chooses the maximum amount
they are willing to pay for a click
on the advert (bid)
The search engine
• Checks advert copy for compliance
to editorial guidelines
• Displays the advert for relevant
search queries
• Determines the rank of the advert
based on bids and quality

Bidding and ranking
Advertisers only pay when
their advert is clicked on pay per click
But they must decide the
most they are willing to pay
for that click - max CPC
This is bidding, and will
determine placement of the
adverts
Every time there is a search,
there is an auction for the
adverts for that search term
Called a Generalised
Second Price Auction (GSP)
Each advertiser pays the bid
of the advertiser below them,
plus a standard increment
Ranking is not just about
bidding
Quality Score has an
effect
• relevance of keywords to search
term
• relevance of advert copy to the
search term
• relevance of the landing page to
the search term

Conversion rates and
click-through rates

The higher up the advert:
• The more clicks on the advert
• The higher the cost per click
PPC Strategy: NB to define goals
Brand exposure:
• many impressions

ROI:

What is the goal of the
campaign?
What do you want users to
do after they have clicked
on your advert?
Goals can be:
• Buying a product
• Booking a plane ticket
• Filling in a form
• Sending an enquiry
• Making a phone call
A user taking the action
you want them to take is a
conversion
Every time the advert is
shown is an impression
A user clicking on the
advert is called … a click
Click-through rate is
clicks / impressions %
Conversion rate is
clicks / impressions %
Click-through rate tells
you how well your copy is
performing
Conversion rate tells you
how well your campaign is
performing
You need to work on both

• Change keyword match types
• Change bids
• Change ad copy
• Improve web site conversion rate
small changes can make a
big difference to your
bottom line
Budgets
• Daily and monthly budgets caps
• You’ll never overspend!
• Advanced bidding options help you
to make the most of your budget
The long tail of search
50% of searches on
Google are unique
This means that the sum
of the unique searches is
the same as the sum of
non-unique searches
Or, there are a few search
terms that are used very
frequently
And many search terms
that are used infrequently
55331 searches for “holiday”
331 for “south african holiday”
Low volume, niche search
terms
• Are more targeted
• Have less competition
• Can have a lower CPC
• And a higher conversion rate
