Pay per click publication
1. Pay Per Click
Paid Search Advertising Setup and Optimization
To practically gauge the success or failure of a pay per click account, advertisers need to
understand certain metrics and what they mean. Here is a simplified account on pay per click
campaign optimization, focused on three factors – keyphrases, ads, and landing pages – and
three metrics – click-through rate, cost per click, and conversion rate.
Keyphrases, Ads, and Landing Pages
Good accounts optimize keyphrases, ads, and landing pages. This is somewhat of an abbreviation for different
reasons. For example, “keyphrases” could more accurately be referred to as “keyphrase matches,” since an ad
gets shown for different query matches and not necessarily different keyphrases, and ads and landing pages
could be broken into more elements, since these terms encompass separate important factors. These three
elements, however, provide a good basis.
A user makes a query, your keyphrases determine whether an ad is shown, the ad determines whether the user
sees the landing page, and the landing page determines whether the user makes a transaction.
Click-Through Rate (CTR)
CTR is affected by keyphrases and ads, landing pages have very little if anything to do with this metric. Given
constant keyphrases, an improvement in CTR means that ad text or position has “improved.” “Improved” means
the ad text captures the attention of the user better, offers something the user is interested in, or is in a higher
position. This does not mean that the ad is more profitable. Given constant ads, an improvement in CTR means
that keyphrases are more relevant to ads or new keyphrases are tapping into a more interested group of
searchers. This also does not mean that the ad is more profitable.
Advertisers who are looking to improve their campaign’s CTR and who have a profitable conversion rate are
trying to get their ads to do more work for them, getting more users to the landing page and possibly reducing
costs in Adwords. Advertisers might also use CTR as a general indicator of a landing page’s conversion rate.
Roughly, if an ad accurately describes what is on a landing page, this might be an acceptable assumption, but
advertisers really shouldn’t rely on this assumption. CTR and conversion rate should be treated as independent
metrics. Advertisers might also try to improve CTR to reduce costs in Adwords since this is a factor in an ad’s
quality score. The relation here is also complicated. Generally, the goal is to find more specific or less
competitive keyphrases, or write better ad text.
If a keyphrase-ad-landing page combination is profitable, advertisers might try to improve click-through rates. If
the combination is not profitable, advertisers should focus on decreasing cost-per-click or increasing conversion
rates.
Cost Per Click (CPC)
For most pay per click programs, cost per click is practically synonomous with bid. Google Adwords complicates
this picture with the quality score. Advertisers can reduce their average CPC without lowering bids by improving
click-through rates, making good landing pages, and writing good ads.

2. Pay Per Click
Paid Search Advertising Setup and Optimization
If an advertiser has a non-profitable keyphrase-ad-landing page combination, he/she might choose to try to
lower his/her CPC. The easiest and best way to do this, even in Adwords, is to lower bids. An advertiser in
Adwords could then try to increase their quality score from a profitable position, increasing their bid if the
quality score is improved enough to make higher positions more profitable.
An advertiser with a profitable keyphrase-ad-landing page combination might choose to raise their CPC to make
the combination more profitable. When doing this, the advertiser should assume that being in a higher ranking
position will not increase conversion rates. There are arguments against this. There are arguments that being in
a lower ranking position will increase conversion rates because the user is more likely to be browsing ad text to
find what they really want instead of just clicking on the first thing he/she sees. Generally, it is best to assume
that CPC and conversion rates are independent metrics. A lot of companies with stars in their eyes, wishing to be
number one for their industry term and looking to increase traffic forget this. Sometimes (most of the time
because the bidding systems in Adwords and Overture cause people to overbid), it is more profitable to be in a
lower position. Unless there is some other value that is not represented in the numbers (brand recognition
might have a value that isn’t represented in conversion calculations), an advertiser should look to see what CPC
maximizes profits and not pay attention to the voice in their head that says they should be number one. Pay per
click advertising is (could be even more if Adwords released the details of their ranking system) very
mathematical. In a world where people had time and energy, algorithms could probably be created to find ideal
bids by taking profit as a function of bids and finding the bid that maximizes profit (using calculus). If there was a
bid management tool that did this, I would buy it right quick.
Conversion Rate
Keyphrases, ads, and landing pages all affect conversion rates. An advertiser should always be trying to improve
conversion rates. This statement needs some qualification. An advertiser can often increase conversion rates by
writing ad text that qualifies the user as someone who is more likely to make a transaction – essentially lowering
click through rates. If a keyphrase-ad-landing page combination is unprofitable, this is a good strategy. If a
keyphrase-ad-landing page combination is profitable, this might not be a good strategy. In this case increasing
the conversion rate could increase return on investment, but decrease overall profit. Similar reasoning exists for
keyphrases. An advertiser could be missing out on good advertising opportunities if they are too selective, not
broad enough, in their keyphrase list.
This aside, given constant keyphrases and ads, an advertiser should always be modifying a site to increase
conversion rates. This means creating content that is directly relevant to what the user is searching for and
easing the transaction process. This entails establishing trust with the user and making the user confident that
he/she is getting what they want at a cost that is better than what they’d get anywhere else.
Conclusion
Conversion rate, cost per click, and click-through rate are three major metrics to gauge the success of or to
improve a pay per click campaign. Most advertisers don’t look at these metrics correctly or get sucked into the
belief that they’re interdependent. These metrics should be treated separately for increasing the profitability of
a campaign. How they should be treated depends on the profitability of the campaign’s keyword-ad-landing
page combinations.
