How Does Google Make Money? The Most Expensive Keywords in AdWords

135

How does Google make its money? On the heels of Google's blow-out Q2 2011 earnings announcement last week, we wanted to find out the most expensive keywords - what keywords demand the highest costs per click and are most competitive in terms of high search volume.

Since the vast majority of Google's profits come from AdWords advertising, these high CPC keyword categories are responsible for a large part of Google's profits. The results of our research are illustrated in an infographic of the most expensive keywords. (Click the image to enlarge the google adwords keywords infographic.)

Most Expensive Keywords

The 20 most expensive keywords categories with the highest search volume (i.e. the most used keywords) and highest costs per click, thereby netting Google the most money, are:

  1. Insurance (example keywords in this category include "buy car insurance online" and "auto insurance price quotes")
  2. Loans (example keywords include "consolidate graduate student loans" and "cheapest homeowner loans")
  3. Mortgage (example keywords include “refinanced second mortgages” and “remortgage with bad credit”)
  4. Attorney (example keywords include “personal injury attorney” and “dui defense attorney”)
  5. Credit (example keywords include “home equity line of credit” and “bad credit home buyer”)
  6. Lawyer ("personal  injury lawyer," "criminal defense lawyer)
  7. Donate ("car donation centers," "donating a used car")
  8. Degree ("criminal justice degrees online," "psychology bachelors degree online")
  9. Hosting ("hosting ms exchange," "managed web hosting solution")
  10. Claim ("personal injury claim," "accident claims no win no fee")
  11. Conference Call ("best conference call service," "conference calls toll free")
  12. Trading ("cheap online trading," "stock trades online")
  13. Software ("crm software programs," "help desk software cheap")
  14. Recovery ("raid server data recovery," "hard drive recovery laptop")
  15. Transfer ("zero apr balance transfer," "credit card balance transfer zero interest")
  16. Gas/Electricity ("business electricity price comparison," "switch gas and electricity suppliers")
  17. Classes ("criminal justice online classes," "online classes business administration")
  18. Rehab ("alcohol rehab centers," "crack rehab centers")
  19. Treatment ("mesothelioma treatment options," "drug treatment centers")
  20. Cord Blood ("cordblood bank," "store umbilical cord blood")

We found that that 97% of Google's revenue comes from advertising on Google sites. In the last four quarters alone (Q3 2010-Q2 2011), Google brought in $32.2 billion in total advertising revenue.

Google CPC: Google's Highest Cost Per Click Keywords

Google AdWords is a dynamic, auction-based marketplace where advertisers bid on keywords to compete for top ad placement. The minimum bid per keyword is 5 cents, but this research shows that in highly competitive categories, Google can make up to $50 per click from PPC keyword bids. Despite a diversified product portfolio, advertising on Google sites accounts for the vast majority of its billions in annual revenue.

The keyword categories with the highest volumes and costs represent businesses with very high lifetime customer value – in other words, these industries can afford to pay a lot to acquire a new customer. These most expensive keywords comprise businesses such as lawsuits, mortgage applications, and server hosting. Some high-volume keyword categories have lower CPCs because advertisers have slimmer margins to expend on PPC advertising.

You can find CPC estimates for keywords using a keyword tool like Keyword Planner or our own Free Keyword Tool.

The Most Expensive Keywords: Survey Methodology

We compiled data from our own trillion-keyword database and the Google Keyword Tool to determine the top 10,000 most expensive English-language keywords over a 90-day period. This keyword list was then organized into categories by theme, such as "Insurance." The largest keyword categories were determined by weighting the number of keywords within each category, as well as the estimated monthly search volume and average cost per click for each keyword.

Tips for Bidding in a Super-Competitive, Expensive Google Adword Key word Niche

If you or your client are struggling to compete in a high-volume, high-CPC keyword category such as the most expensive keywords identified in this study, the PPC best practices are the same as always, except of course, the stakes are 1000x higher if you’re paying on average $50 per click vs. $0.05 per click. Here are a few tips to consider:

  • Quality Score: High Quality Scores can help lower your average Google CPC. Tools like the Keyword Niche Finder and Keyword Grouper to break up larger keyword lists into smaller, more targeted lists which will enable you to write more targeted ad text and landing pages which should help improve relevancy and Quality Score.
  • Be Specific: Target specific, 3-5 word keywords. Use a keyword tool to generate specific keyword ideas, and use keyword match types to ensure you’re only paying for keywords that are very specific to your business.
  • Use Negative Keywords: Use a negative keyword tool to help figure out what kinds of words you’re likely to be matched against and weed out keywords that aren’t relevant to your business.
  • Be Relevant
  • Landing Page Optimization: The average conversion rate for just about anything on AdWords is around 2%. But we often see landing pages converting at the 20% or even 30% range. The key to landing page optimization is to keep trying out different types of offers and testing how people respond to them.

I would like to address the pie chart listing Insurance at 24% when it clearly looks like it is visually closer to 31%? Is it the numbers or the chart that is off, and what are you trying to get us to perceive here?If it is 24%, 12% and 9% for the top three categories, then the last time I checked those three combined should cover less than half of the shiny colorful circle thing.

Interesting article, shame the infographics didn't load.  Trying to do research on the most competitive kw's in order to dissect their seo tactics and copy them.  At the moment using majestic seo, after trialling semozfor their free trial. seomoz definitely a lot more user friends vs majestic, although majestic seems to index quicker and be more up to date. Is this article just for US traffic (my niche is ex-US).

 The representation regarding the 3 Most expensive keywords in Google Adwords advertising. The Insurance fields with surely the must too spend in an industry without spending limit's got the top spot as the 800 pound Gorillia in the room a lot of people are dealing mostly about the insurance business. Loans and Mortgage the crashing industry are second and third respectively. The infographics colorful and interesting. Nice article..but the keywords listed are almost impossible to rank for..it will take 1 or 2 or even 3 years of hard work and great expense to reach those spot's.. But still a great resource for affiliate marketers,the influence of the economy on some of these keyword moving up and down is of course very large, but ..........Thanks! Great resource!                           MOMU PilMagic

Great information, thank you. Although, I manage PPC for clients in these categories, and the highest I've ever had to pay to be No. 1 was about $11. I think whoever created this original information ironically may have been bad at AdWords management!

Google says it has three million customers that are used to generate a turnover of about $37bn and I cannot argue with how much revenue Google may get from Amazon or Ebay but I have to take  exception when it comes to the number of customers as being as high as three millions.Currently I am working on a project that monitors a few hundred thousand parked domain / Cyber squatters that all use Google for adverts on these parked domains and some of these domains are giving out viruses that click the PPC/CPC links that lead back to Google-Lead-Services and Google's Double-Click and I record the Url of each target site of from Google advert in a database and to be honest I was expecting to see a couple of million records but I am struggling to find even 100k individual Urls and domain names and I have been using IP-Address based everywhere from India to the USA since Google's results are location specific.Bottom line is Google is not sharing all the adverts from these 3m customers across the board so I need to go more direct or something very strange is going on and I cannot put my finger on it so maybe someone here can advise me as to where I maybe going wrong with my calculations.

I have some questions:1) I keep redaing to chose keywords with high search volume and low competition. Why??? that competition is not how many pages are outthere taking about the same thing, but advertizers that comeete for that word. Wouldn't it be better to point out one with high advertizer competition? I don't get it.2) Do I have to make the title of my condition Work from home California or can I make it something more logical like work from home in California

What are the cheapest words to bid? It means that there is almost no competition for those words that could be used to sell products via inexpensive ads.

I'm not surprised with the top 5 or so but I think that there are some really untapped gems towards the bottom of your list.While I think you've provided some invaluable tips for people looking to bid for these gold-plated type keywords, I'd recommend they take a look at the power of getting a top organic listing via a wordpress blog (hint: buy the domain containing the exact match domain you're targetting). It's a lot faster and easier than most will have you think.Thanks for this Larry.
