Search Engine Marketing: buying
your way to the top!
In this month’s edition of Konstrukt, I’m
going to let you in on a secret that will almost certainly change
the way you market your business online – and quite possibly
offline - forever.
This secret is pay-per-click advertising.
Some of you may have heard of it. Some of you may be already using
it. Almost certainly, none of you are using it to its full potential.
PPC Advertising (pay-per-click) can be categorised into
all the paid listing offerings by search engines around the world.
In this article I’m going to:
| Point 1 |
Explain the basics of PPC Advertising; (To view

| Point 2 |
Demonstrate how to create your own PPC Campaign; and |
| Point 3 |
Show you how to fine tune your campaigns to maximize their
revenue earning potential and achieve a staggeringly low cost
per sale.

Creating your campaign
Choosing search terms
Both Overture and Google will require you to set up some campaigns
in advance. Don’t get too nervous here – anything you
add can be changed later!
The first step is to choose your search terms. This may sound easy…
it can actually be quite difficult. The problem is trying to get
yourself to think like your customer would think. For example, let’s
say I want to run an ad for my company. I want to target people
who need web development services (for example). I might take this
approach:
Search terms: web
development, web
development services, web
development Brisbane etc.
Now if I take a quick look in Overture’s “Search Term
Suggestions” tool it will tell me that I’m likely to
get up to 53 impressions per month – total number of click
throughs = 1!
Now I don’t proclaim to be a rocket scientist, but the odds
of me ever growing a business with one click through (it’s
not even an enquiry yet!) seem pretty slim. The problem is that
my potential customers don’t ever refer to “web development”
– they think in terms of “web pages” and “web
sites”. Let’s change my search term to “web sites”.
WHOA! Overture
now tells me that for search terms related to “web sites”
I can get 10’s of 1000’s of impressions per months and
thousands of click-throughs. Of course I wouldn’t choose all
the search terms they suggest, but this does illustrate how important
it is to choose your words carefully and think in terms of the customer’s
search (not necessarily what you would search for!)
Google has
a similar tool called the “Keyword Estimator”
– one which I prefer in fact! The Keyword Estimator will tell
you forecasted clicks per day, average cost per click, cost per
day and average position. With Google you will need to input a maximum
cost-per-click before it will estimate, but that’s no biggie,
you can always change it later!
Setting your bid
Your bidding calculation should be based on three factors:
1. Your search engine marketing budget
2. Your maximum allowable cost per enquiry and cost per sale
3. Your capacity to fulfill orders
Your search engine marketing budget may be determined by yourself,
it may be determined by your Marketing Manager, it may be determined
by your CEO. All that aside, if search engine marketing proves to
provide a lower cost per sale than other mediums, you should throw
as much money at it as you can!
More important than your budget is your maximum allowable cost
per enquiry and cost per sale. Of course we want to keep both these
as low as possible, but it is important you understand what they
are before you go diving head first into a bidding war!
Let’s assume, for instance, you sell computers online. Your
gross profit on your computers is $400. You estimate your current
net profit to be $200 per computer. Now it doesn’t make a
lot of sense to go and bid $10 per click through to your site when
you know darn well you won’t convert 1 in 20 click-throughs!
That said, if the lifetime value of a customer (in repeat sales,
software purchases and upgrades etc.) is closer to $3000 net profit,
it may indeed make sense to bid $10 per click.
Determining your allowable cost per enquiry
and per sale
When considering your allowable cost per enquiry or sale you
must first consider the lifetime value of a client. Let’s
say this value is $3000.
Arguably, if we spend any less than $3000 in making someone a
customer we will make a profit.
Of course, a $1 profit in this scenario is a fairly risky proposition,
so let’s say we set our allowable cost per sale at $1500.
How do we now calculate our allowable cost per enquiry? First
determine your current conversion rate from enquiry to sale. Let’s
say this is 20%. Multiply $1500 by 20% and voila – your
allowable cost per enquiry is $300.
Of course, this is only an estimate and we will need to monitor
this estimate carefully over time. Should conversion rates increase
we may want to increase our allowable cost per enquiry. Should
they decrease we will probably want to decrease that allowable
cost quite quickly!
Now that we understand what our allowable cost per sale and cost
per enquiry are (or at least we’ve hazarded a guess!), it’s
time to calculate our allowable cost per click.
Initially this WILL BE an estimate. We don’t know yet how
many people are going to go from being a visitor to being an enquiry.
Luckily for us, both Google and Overture will provide us with the
tools to measure this over time.
Let’s be conservative and estimate that 1 in 60 site visitors
will request further information. This makes our allowable cost
per click $5. So we certainly won’t be bidding over this amount
initially.
That doesn’t necessarily mean we want to go ahead and set
our maximum bid at $5. We just want to ensure that we generate sufficient
enquiries for our sales team to close. This is where capacity comes
into play. If you go crazy and outbid every competitor on every
conceivable search term there’s a good chance your traffic
and enquiries (and costs!) will go through the roof. Unfortunately
for you, both your sales and production teams are finite resources,
so only aim to fill that capacity – not overflow it!
Both Overture and Google have their own tools which will help you
set your maximum bid and hence estimate traffic and your relative
position in search results. Overture will even show you who you
are bidding against and how much they are bidding!
Writing your Ad
Here’s the fun part. You have one heading and two lines of
copy to sell yourself. Lucky you’re an expert copywriter!
Of course, for most of us mere mortals we’ll need to put
some more thought into this. The most important thing to consider
when writing your ad is relevance. Go back to your search terms
– this will tell you what people who are seeing your ad are
looking for!
Let’s assume our search term is “web sites” again.
Chances are, people searching for “web sites” are either
looking to get theirs built, or are sneaky designers like me going
to check out the competition!
Assuming the former, we want an ad that will appeal to someone
who wants their website built. What appeals to this audience? Price,
speed, quality, information? We’re only guessing anyway –
so why not write an ad for each!

Now before you give me a hard time on my copywriting, I just wrote
these up for the purposes of demonstration!
As you can see, our existing ad is pulling in a 1.1% CTR (Click-through
rate). If I leave up my four new ads, Google will soon tell me which
ads outperform the others. This is extremely valuable information!
Imagine if one of my new ads started pulling in a 5% CTR. I would
then start writing more ads based upon the content of that ad. One
of those ads might pull a 6% response and away I go again!
As you can probably already gather, the combinations of ads, search
terms and bids are immeasurable. How to determine the best mix for
you will be a case of trial and error (and persistence!)
