The Effect of Activating Google AdWords Sitelinks

Posted: 08 Dec 2010 05:00 AM PST

Posted by Petter El Fakiri

Around one year ago Google announced that sitelinks could be added to Google AdWords ads. What's the effect of this feature on users' click patterns?

A company I have been working with activated sitelinks in their AdWords ads on search for CompanyName. They also ranked #1 organically on this search phrase. From experience it is smart to advertise with the company name as long as the paid clicks are cheap and give the AdWords campaign high quality. But was it right to activate sitelinks as well?

Having activated sitelinks, the company soon experienced a substantial change to their click profile for users coming from Google. Sitelinks were disabled for the company name after 11 days, it was time to dig in and investigate the effects.

The two following graphs show the traffic from Google where the search keyword is CompanyName. The first graph shows traffic from Google AdWords and the second traffic from organic Google. The effect on traffic from Google is obvious.

Visits from Google AdWords - search phrase "CompanyName"

Visits from Google Organic - search phrase CompanyName

During the period with sitelinks enabled, traffic from Google AdWords dramatically increases, while the organic traffic decreases.

Below is a comparison of the traffic before AdWords sitelinks where enabled and the traffic during activation. Both graphs show traffic from Google on CompanyName search. As you can see; between the periods the total traffic from Google on search phrase "CompanyName" is up less than 1%. The periods have comparable traffic quantities.

Comparison - period with and without Google AdWords Sitelinks    

In the period when AdWords Sitelinks was active there was a 91% increase in traffic from Google AdWords, shown by the next graph. This translates to about 2700 hits per day for this single search term.

  Change in traffic from Google AdWords in the two periods  

Finally the following graph illustrates what happened to organic traffic during the same two periods. The traffic is down almost 25% on searches for CompanyName, where the last period is the one where sitelinks was enabled in AdWords.

Change in traffic from Google Organic  

Pretty pictures are one thing, but often the numbers can be more persuasive:    

The statistics show that the number of visits from organic search is down by roughly the same amount that the traffic from paid search is up.
Assuming a CPC of 0,30NOK (about 5 cents) on CompanyName in AdWords, means 300.000 NOK ($ 50 000) per year in extra Google AdWords cost if our client activates Google AdWords Sitelinks. With no traffic increase to show for it!

Considering Google allowed purchasing of competitors names in our corner of the world about two months ago, this will probably drive the CPC for company names up significantly.

Increased cost for the company aside, the changed click pattern is also noteworthy from a SEO perspective. During the period without AdWords Sitelinks the ratio between organic and paid results was 78/22, which is close to what SEO's consider a normal distribution. When AdWords Sitelinks where active the ratio changed to 59/42. Google has drastically changed the click pattern by allowing Sitelinks in AdWords ads, at least in this case.

Are Sitelinks something to avoid? Of course not! There are many solid and valid arguments for ads using the company name with Sitelinks enabled. The clicks are often cheap, they always have high CTR and ranking. This is the foundation for a well managed AdWords account of high quality, good ranking and nice click prices once the whole account is considered.

Please let us know if anyone else has similar experiences with Google AdWords Sitelinks.

Google Places SEO: Lessons Learned from Rank Correlation Data

Posted: 07 Dec 2010 01:14 PM PST

Posted by randfish

In early June of this year, SEOmoz released some ranking correlation data about Google's web results and how they mapped against specific metrics. This exciting work gave us valuable insight into Google's rankings system and both confirmed many assumptions as well as opened up new lines of questions. When Google announced their new Places Results at the end of October, we couldn't help but want to learn more.

In November, we gathered data for 220 search queries - 20 US cities and 11 business "types" (different kinds of queries). This dataset is smaller than our web results, and was intended to be an initial data gathering project before we dove deeper, but our findings proved surprising significant (from a statistical standpoint) and thus, we're making the results and report publicly available.

As with our previous collection and analysis of this type of data, it's important to keep a few things in mind:

  1. Correlation ≠ Causation - the findings here are merely indicative of what high ranking results are doing that lower ranking results aren't (or, at least, are doing less of). It's not necessarily the case that any of these factors are the cause of the higher rankings, they could merely be a side effect of pages that perform better. Nevertheless, it's always interesting to know what higher ranking sites/pages are doing that they're lower ranking peers aren't.
  2. Statistical Signifigance - the report specifically highlights results that are more than two standard errors away from statistical significance (98%+ chance of non-zero correlation). Many of the factors we measured fall into this category, which is why we're sharing despite the smaller dataset. In terms of the correlation numbers, remember that 0.00 is no correlation and 1.0 is perfect correlation. It's in our opinion that in algorithms like Google's, where hundreds of factors are supposedly at play together, data in the 0.05-0.1 range is interesting and data in the 0.1-0.3 range potentialy worth more significant attention.
  3. Ranked Correlations - the correlations are comparing pages that ranked higher vs. those that ranked lower, and the datasets in the report and below are reporting on average correlations across the entire dataset (except where specified), with standard error as a metric for accuracy.
  4. Common Sense is Essential - you'll see some datapoints, just like in our web results set, that would suggest that sites not following the  commonly held "best practices" (like using the name of the queried city in your URL) results in better rankings. We strongly urge readers to use this data as a guideline, but not a rule (for example, it could be that many results using the city name in the URL are national chains with multiple "city" pages, and thus aren't as "local" in Google's eyes as their peers).

With those out of the way, let's dive into the dataset, which you can download a full version of here:

  • The 20 cities included:
    • Indianapolis
    • Austin
    • Seattle
    • Portland
    • Baltimore
    • Boston
    • Memphis
    • Denver
    • Nashville
    • Milwaukee
    • Las Vegas
    • Louisville
    • Albuquerque
    • Tucson
    • Atlanta
    • Fresno
    • Sacramento
    • Omaha
    • Miami
    • Cleveland
  • The 11 Business Types / Queries included:
    • Restaurants
    • Car Wash
    • Attorneys
    • Yoga Studio
    • Book Stores
    • Parks
    • Ice Cream
    • Gyms
    • Dry Cleaners
    • Hospitals

Interestingly, the results we gathered seem to indicate that across multiple cities, the Google Places ranking algorithm doesn't differ much, but when business/query types are considered, there's indications that Google may indeed be changing up how the rankings are calculated (an alternative explanation is that different business segments simply have dramatically different weights on the factors depending on their type).

For this round of correlation analysis, we contracted Dr. Matthew Peters (who holds a PhD in Applied Math from Univ. of WA) to create a report of his findings based on the data. In discussing the role that cities/query types played, he noted:

City is not a significant source of variation for any of the variables, suggesting that Google’s algorithm is the same for all cities. However, for 9 of the 24 variables we can reject the null hypothesis that business type is a not significant source of variation in the correlation coefficients at a=0.05. This is highly unlikely to have occurred by chance. Unfortunately there is a caveat to this result. The results from ANOVA assume the residuals to be normally distributed, but in most cases the residuals are not normal as tested with a Shapiro-Wilk test.

You can download his full report here.

Next, let's look at some of the more interesting statistical findings Matt discovered. These are split into 4 unique sections, and we're looking only at the correlations with Places results (though the data and report also include web results).

Correlation with Page-Specific Link Popularity Factors

Google Places Correlations with Page-Specific Link Popularity Elements

With the exception of PageRank, all data comes via SEOmoz's Linkscape data API.

NOTE: In this data, mozRank and PageRank are not significantly different than zero.

Domain-Wide Link Popularity Factors

Google Places Domain Link Factor Correlations

All data comes via SEOmoz's Linkscape data API.

NOTE: In this data, all of the metrics are significant.

Keyword Usage Factors

Google Places Keyword Usage Correlations 

All data comes directly from the results page URL or the Places page/listing. Business keyword refers to the type, such as "ice cream" or "hospital" while city keyword refers to the location, such as "Austin" or "Portland." The relatively large, negative correlation with the city keyword in URLs is an outlier (as no other element we measured for local listings had a significant negative correlation). My personal guess is nationwide sites trying to rank individually on city-targeted pages don't perform as well as local-only results in general and this could cause that biasing, but we don't have evidence to prove that theory and other explanations are certainly possible.

NOTE: In this data, correlations for business keyword in the URL and city keyword in the title element were not significantly different than zero.

Places Listings, Ratings + Reviews Factors

Google Places Listings Correlations 

All data comes directly from Google Places' page about the result.

NOTE: In this data, all of the metrics are significant. 

Interest Takeaways and Notes from this Research:

  • In Places results, domain-wide link popularity factors seem more important than page-specific ones. We've heard that links aren't as important in local/places and the data certainly suggest that's accurate (see the full report to compare correlations), but they may not be completely useless, particularly on the domain level.
  • Using the city and business type keyword in the page title and the listing name (when claiming/editing your business's name in the results) may give a positive boost. Results using these keywords seem to frequently outrank their peers. For example:

    Portland Attorneys Places Results
     
  • More is almost always better when it comes to everything associated with your Places listing - more related maps, more reviews, more "about this place" results, etc. However, this metric doesn't appear as powerful as we'd initially thought. It could be that the missing "consistency" metric is a big part of why the correlations here weren't higher.
  • Several things we didn't measure in this report are particularly interesting and it's sad we missed them. These include:
    • Proximity to centroid (just tough to gather for every result at scale)
    • Consistency of listings (supposedly a central piece of the Local rankings puzzle) in address, phone number, business name, type
    • Presence of specific listing sources (like those shown on GetListed.org for example)
  • This data isn't far out of whack with the perception/opinions of Local SEOs, which we take to be a good sign, both for the data, and the SEOs surveyed :-)

Our hope is to do this experiment again with more data and possibly more metrics in the future. Your suggestions are, of course, very welcome.


As always, we invite you to download the report and raw data and give us any feedback or feel free to do your own analyses and come to your own conclusions. It could even be valuable to use this same process for results you (or your clients) care about and find the missing ingredients between you and the competition.

p.s. Special thanks to Paris Childress and Evgeni Yordanov for help in the data collection process.

Seth's Blog : Where's your platform?

[You're getting this note because you subscribed to Seth Godin's blog.]

Where's your platform?

That needs to be the goal when you seek out a job.

Bob Dylan earned the right to make records, and instead of using it to create ever more commercial versions of his old stuff, he used it as a platform to do art.

A brilliant programmer finds a job in a small company and instead of seeing it as a grind, churning out what's asked, he uses it as a platform to hone his skills and to ship code that changes everything.

A waiter uses his job serving patrons as a platform for engagement, for building a reputation and for learning how to delight.

A blogger starts measuring pageviews and ends up racing the bottom with nothing but scintillating gossip and pandering. Or, perhaps, she decides to use the blog as a platform to take herself and her readers somewhere they will be glad to go...

There's no rigid line between a job and art. Instead, there's an opportunity. Both you and your boss get to decide if your job is a platform or just a set of tasks.

Google the Answer Engine

Posted: 07 Dec 2010 07:31 AM PST

Post image for Google the Answer Engine

One of the topics that emerged from Pubcon was “Should SEO’s Focus on Where Google is Heading”, and I’m going to agree with Aaron that focusing on short term algorithmic holes isn’t a smart thing for most people (churn and burn folks–you keep on keeping on). I agree that most publishers should focus on where Google is going. However, the one thing I think publishers need to be aware of and be wary of is Google’s transition to becoming an answer engine.

this represents a clear and present danger to every web publisher…
When I refer to Google trying to become an answer engine, what exactly do I mean? I mean that Google will provide the answer right on the SERP itself if possible and, more frequently, from a Google-owned or Google-maintained property. What exactly do I mean by that? I would be willing to bet that at least one Googler is hunched over a monitor somewhere trying to figure out how to convert voice searches into standardized results. Get out your best Jean Luc Picard impersonation, grab your android phone, and say “COMPUTER … Show me airline prices from Los Angeles to Las Vegas on March 15th.” Now imagine that Google, using its recently acquired ITA travel data, could show you the 5 cheapest flights without needing to send you to the airline, travelocity, or any of the other intermediaries.  Good for Google, good for the user … but scary if you are a publisher.

Google has been moving in this direction for years with queries like [what is george washington's birthday]

There’s no need for the person performing that query to visit any website because Google became the answer machine.  Earlier this year, they began making inroads in commercial searches for things like [mortgage rates]

Google’s latest incursion into becoming the answer machine came from its local results when they began stealing … err aggregating … reviews from other sites and mixing them with their own on place pages.

IMHO this represents a clear and present danger to every web publisher. For a while, Google will be content to let publishers keep serving the information that Google hasn’t figured out how to gather efficiently/profitably, even if that means referring users to low quality, demand media style pages from About.com and eHow.com. However there’s no doubt in my mind that once Google thinks they can do better, they will scrape your data and throw you under the bus without a second thought … cause it’s all about the users, right?

The one exception that may leave you a leg to stand on is if you are a brand and are building some sense of brand loyalty. If users type in [<brand name> + <keyword phrase>] Google will show less “Google answers”. For example [george washington's birthday wikipedia] or [bank of america mortgage rates] contain none of the Google properties. Of course, it would seem to me that this is a massive conflict of interest as far as Google is concerned, but I’m not a legislator, so what do I know.

The days of being a pure affiliate and building sites without any thought to branding are coming to a close. They will never disappear completely, but there will be less of them. The purely keyword-based traffic without a hint of branding is going to become more competitive and, in some cases, you will be competing with Google itself or with Google owned properties like Boutiques.com. Heed these warnings Caesar and fear the Ides of March …

Seth's Blog : The Domino Project

[You're getting this note because you subscribed to Seth Godin's blog.]

The Domino Project

Book publishing is changing. It's changing faster than it has in a hundred years. I've been persistent enough to be part of that change, provoking and poking and wondering about what comes next.

Today, I'm thrilled to report on what's next for me.

  • To reinvent the way books are created when the middleman is made less important.
  • To reinvent the way books are purchased when the tribe is known and embraced.
  • To reinvent the way books are read when the alternatives are so much easier to find.
  • To find and leverage great ideas and great authors, bringing them to readers who need them.

The notion of the paper book as merely a package for information is slowly becoming obsolete. There must be other reasons on offer, or smart people will go digital, or read something free. The book is still an ideal tool for the hand-to-hand spreading of important ideas, though. The point of the book is to be spread, to act as a manifesto, to get in sync with others, to give and to get and to hand around.

Our goal is to offer ideas that people need and want to spread, to enjoy and to hold and to own, and to change conversations.

Working with a great team at Amazon, I'm launching a new publishing venture called The Domino Project. I think it fundamentally changes many of the rules of publishing trade non-fiction.

Trade publishing (as opposed to textbooks or other non-consumer ventures) has always been about getting masses of people to know about, understand and read your books. The business has been driven by several foundational principles:

1. The middleman (the bookstore) has a great deal of power. There's only a limited amount of shelf space, and there are more books (far more books) than we have room for. No display, no sale. That's one reason books are published with the economically ridiculous model of 100% returns from bookstores. Huge stores can carry thousands of books and return them if they don't sell. Large chains get a say about what's on the cover, what the title is, and they even get paid for shelf displays.

2. The audience (the reader) is largely unknown to the publisher, and thus to the author. Authors with large followings still have to start over with each book, because they don't have permission (or the data) to contact loyal readers directly.

3. Pricing and product are static and slow. Once a book is published, the price is set forever. Add to that the glacial speed from conception to publication date and you see a system that is set up to benefit neither the publisher nor the reader.

4. Books are inherently difficult to spread. The ideas in books might travel, but the act of recommending a book, having the idea stick and a new sale get made is slow or broken. Given how important the ideas in books are, this chain has many weak links. It's worth rethinking how a publishing house could organize around its ultimate goal, which is to spread ideas.

The internet and the Kindle are changing all of these rules. The Domino Project is designed to (at least by way of example) remap many of these foundations.

1. There is no middleman. Because there is infinite shelf space, the publisher has more control over what the reader sees and how. In addition, the Amazon platform allows a tiny organization to have huge reach without taking significant inventory risk. "Powered by Amazon" is part of our name—it describes the unique nature of the venture... I get to figure out the next neat idea, and Amazon can handle printing, logistics and the platform for connection.

2. The reader is tightly connected with the publisher and the author. If you like the sort of things I write or recommend, you can sign up here (for free, using your email) and we can alert you to new works, send you free samples and otherwise make it easy for you to be smart about the new ideas that are generated. (RSS works too).

3. Pricing can vary based on volume, on timing, on format. With this project, I've made the decision to ignore the rules that publishers follow to get on the New York Times bestseller list. There's no point in compromising the consumer experience or the product merely to get a nice ego boost and a small shot of promotion. More on this in a future post, but I'll let you use your imagination.

4. Digital goods and manifestos in book form make it easier to spread complex ideas. It's long frustrated me that a blog post can reach 100 times as many people as a book, but can't deliver the nuance a book can. The Domino Project is organized around a fundamentally different model of virality, one that allows authors to directly reach people who can use the ideas we're writing about.

The Domino Project is named for the domino effect—ideas can quickly spread, moving through a previously static set up. Our mission isn't to become a promotional machine, focused on interrupting large numbers of people or having significant promotional chops through traditional media. Instead, we're grabbing the opportunity to choose and deliver manifestos that are optimized for the tribe, for the small group that wants to grab them, inhale them and spread them. The good ones will spread, first from person to person, then from one circle to another, and eventually into large groups.

That's a lot to absorb for one post. I've been working on the ideas behind The Domino Project since I published my very first book in 1986. The first manifestos won't be out for a few months, but you can learn more as we go by following the Domino Project blog here.

PS When we roll out our books, there will be sneak previews and other goodies for those first on the list...
