5 Killer SEO Insights from Analyzing a Billion Dollars in AdWords Spend (2024)

Last week, I analyzed a Billion dollars of annualized AdWords Spend.

Woot! No kidding. Over a billion dollars (USD). That's a lot of clicks!

Earlier last week, I published my findings in an infographic.In my article today, I’ll share with you my top five SEO insights and strategiesfrom having poured over all this paid search data for nearly an entire week.

Why should you care? By understanding what’s happening on the paid search side of the Google SERP, you can better understand and anticipate trends in organic search.Kind of like how that Sun Tzu guy says to keep your enemies closer in his art of war thing! (Not that paid search is the enemy or anything - but you know what I mean - it's just good to know.)

So without further delay, drum roll, please …

5.Global Average Cost per Click Data by Industry

Most SEOs will inevitably be asked, at some time by an employer or client, what the value of their work is. It’s a legitimate question, but can be challenging to quantify. In my study, I calculated the global average CPC’s for Q3, 2012 for the top 10 industries in Google in US dollars. Now, at a minimum, you can now tell your stakeholder how much it would cost to buy those organic clicks, on average. Here they are ordered by cost:

1. Finance -- $3.09
2. Jobs & Education -- $1.80
3. Business & Industrial -- $1.67
4. Computers & Electronics -- $1.39
5. Internet & Telecom -- $1.11
6. Beauty & Fitness -- $1.11
7. Autos & Vehicles -- $0.97
8. Home & Garden -- $0.76
9. Travel -- $0.29
10. Shopping -- $0.25

You might be thinking, wait - aren’t paid clicks worth more like $50+ per click? Those are the outliers in highly competitive markets. On average, paid clicks generally cost less, particularly when you include clicks from outside of the US into the mix as I did. If your industry wasn’t listed here, I found that global average cost per click on Google Search (including the Google Partner Search Network) worked out to $0.53 USD in Q3, 2012.

Also, this isn’t to say that the value of SEO is limited to just the cost of paying for the clicks that get generated; there are other business benefits of SEO beyond just clicks. For example, blogging and content marketing can help establish thought leadership, and the value of the sales and leads derived from those clicks. Think of this as just one additional way to quantify the value of your SEO work in a very concrete way.

4. Local, Mobile Search Highly Effective for SEO?

When Google released their "disappointing" Q3 Earnings this month, their stock was crushed - down by 10% in a single day. According to Google, CPC’s were down by “approximately 15%”and year over year advertising revenue growth rates declined from 21% to 16%. Industry analysts are placing the blame for slowing ad revenue growth rates squarely on mobile search, which is said to monetize on average at roughly half the value of a desktop search. Why?

Mobile ad engagement is lower in comparison to ads on the desktop, which intuitively makes sense. When you’re doing a Google search on your smartphone, you’re likely on the go somewhere, and probably less likely to be tempted to click on an ad that isn’t absolutely critical to what you’re looking for in that moment. There’s also considerably less real estate for ads compared to the desktop. These issues are most certainly impacting Google revenue growth as mobile search volume is expected to exceed desktop search volume by the end of 2014.

The upshot of this trend from an SEO perspective is that if a mobile search is monetizing at half the rate of a desktop search, then we can deduce that an organic search listing from mobile search has a greater chance of being clicked on than the same search executed on the desktop. Furthermore, since one in three mobile searches have location based intent (for example, finding a nearby business), I’d argue that there is a tremendous opportunity to be had in SEO on mobile devices, particularly for searches with local intent!

3. A Huge Increase in Paid Clicks and Impressions

Unfortunately, this one isn’t as good of news for the SEO industry as the last one. (I’m trying to be balanced here!) If you don’t want to hear any bad news, I’d recommend just jumping ahead to the next item in the list.

According to Google, average CPC’s fell by “approximately 15%” (they didn’t give a precise number), My own research pegged that number at far higher a value (down 16.5% on Google Search and down 18.2% on Google Display Network over just the last two quarters!). I also found mixed click-through rates: down 12.4% on Google Search, and up 13.8% on Google Display Network in the last two quarters.

Yet despite these strong headwinds, Google’s total advertising revenues were still up around 3% for the quarter and 16% for the year.

How did they manage to pull that off?

By growing clicks and impressions like crazy, that’s how.

By my estimates, clicks were up 21.6% in the last two quarters for Google Search and up 29.1% for Google Display Network in the last two quarters.

Now, here’s where the math gets really crazy.

Assume that in order to keep Wall Street happy over the next 12 months, Google needs to keep their revenue growth at or above their historical average 20% growth rate. If CPC’s continue to drop by another 15% in the next year (which I believe it will as huge increases in available ad impressions reduces competition and impacts cost per click), then Google will have to grow clicks and impressions in a big way to make up for the revenue hit. How big, you ask?

Paid clicks from Google Search would have to grow from my estimated 193.2M clicks per day today, to 273.6M clicks per day – that’s up 41.6%. The number is incredibly high because it’s required to both grow ad revenues while simultaneously offsetting lower average cost per click prices.

But wait, there's more.

In order to get those 273.6M clicks per day if CTR’s fall by 15% as they have in the last year (naturally, with more ads being shown per search, the likelihood that any one ad gets clicked on by definition must fall), Google would have to have to grow ad impressions from my current estimate of 5.6 billion impressions per day, to 9.2 billion impressions per day – that’s up a whopping 64.3%, again to drive both the needed additional clicks while simultaneously making up for the decrease in average click through rates.

So, where are these searches going to come from? Probably from more of the same of what we saw in the last year, including:

• More ads in SERPS: Just as Google has introduced bigger and more prominent more ads on the top, bottom, and the side of a SERP in the past year, I’d expect to see more of this treatment for increasingly diverse types of queries.
• New advertising products: Similar to how Google converted their Product Listings from organic search into a purely paid model earlier this year, it would not surprise me if Google Business Listings Pages evolved into a commercial model, or if more ads start showing up in Google Maps, etc. I’d also expect to see more verticalized search formats, like Google Flights, but targeting the other top 10 industries identified in my study.
• Natural query growth: Query volume on Google goes up every month, so some increases in clicks and impressions should come naturally.

The takeaway here is that I expect to see more and more share of clicks being accrued to the paid search column, and from that perspective, it just becomes harder and harder to ignore paid search.

2. Average Paid Search CPC’s are Going Down

As previously mentioned, Google reported that the average CPC dropped by “approximately 15%” (they did not provide an exact figure), and my own calculations found a similar decline.

Many marketers believe that channel diversification is an important element of any marketing plan; to not have all your eggs in one basket is key. If your company already leverages paid search, the change means that you can expect on average to have access to a larger available inventory of impressions, combined with lower CPC, which means that advertisers can literally get more customers for less money.

For those of you who are not doing paid search, last month I wrote an article on using AdWords Data for SEO, explaining how it’s potentially an incredible treasure trove for SEO Keyword Research. If you were on the fence about giving that a try, it should be, on average, cheaper and faster to execute that strategy today.

1.Google Display Network Incredibly Effective and Complementary to SEO Efforts

In my study, I found that the average conversion rate for Google Search in Q3 2012 was 5.63%, compared to an average conversion rate for the Google Display Network of 4.68%. (Wow!)

I was surprised to see just how effective conversion rates were on the Google Display Network, so I calculated and compared conversion rates for all of the top 10 industries for both Google Search and Display (see below). Notice how there are some industries where the Google Display Network had higher conversion rates than Google Search.

Intuitively, combining SEO and remarketing makes a lot of sense. After all, we work so hard on developing our content to get people to the site, but conversion rates are generally in the single digits. Retargeting enables us to stalk relentlessly market to those ~95% of visitors that didn’t convert, following them across the web from one site to the next until they finally click and convert to a sale.

In the Travel Industry, Google Display Advertising had a higher conversion rate than Google Search.

I recently listened to Rand speak at a conference in Boston. In his talk, he said that SEOmoz uses search retargeting on the Google Display Network and concluded that (and I’m paraphrasing here – apologies to Rand if I didn’t get this exactly right): “What can I say, it works for us!”.

I think he’s right, and now I have some additional data to prove it.

A Bonus Insight: Find Your Next SEO Job or Client!

Looking to land your next SEO job or agency client? Here’s an approach: start with the industries and companies that are spending the most on search. It shouldn’t be too hard to convince them of the value of something they’re already spending so much on.

As part of my research, I calculated the top 10 industries that spent the most in paid search in Q3, 2012, and used publicly available spyfu data to approximate the top 5 spenders in each of the industry. They are:

• Finance -- State Farm, Geico, Quicken Loans, Capital One, Bank of America
• Travel -- Expedia, Hotels.com, Booking.com, Priceline.com, Kayak
• Shopping -- Amazon, eBay, JC Penney, Walmart, Sears
• Jobs & Education -- University of Phoenix, Monster.com, ITT-Tech, Devry, Kaplan
• Internet & Telecom -- AT&T, Sprint, T-mobile, Verizon, Comcast
• Computers & Electronics -- Bestbuy, Apple, HP, Microsoft, Newegg.com
• Business & Industrial -- Yellowpages, Staples, uline, Vistaprint, Office Depot
• Home & Garden -- Lowes, Home Depot, Servicemagic, Kohls, Pottery Barn
• Autos & Vehicles -- Edmunds, KBB, Autotrader, Ford, cars.com
• Beauty & Fitness -- QVC, Walgreens, Sephora, Underarmor, Maybelline

In addition to these companies and industries understanding the value of search, I’ve also found that it can be a lot more fun working at or with companies where search plays such a critical element in their overall their marketing strategy, as opposed to industries or companies that are completely clueless when it comes to search.
