Even though the advertising industry is a 200$ billion dollar industry, which is about 2% of GDP, it has been difficult for economists to study and understand it.  However, on-line advertising is contributing to the ability to cross this gap through the possibility of linking advertising to conversions at a low cost and that ads that are served can be served randomly in order to reduce biases.  Although internet data has allowed companies to focus on click through rates, it must be remembered that these are only an intermediate step from the ad being served to the ultimate goal that is desired. However, these variables are used as dependent variables that can be matched with tendencies and intentions.  The data that is now very collectable and provides an opportunity to create algorithms also leads to the potential to draw incorrect assumptions based on the large amount of data.  Most models assume that if one has not clicked on the link, it does not affect purchasing behavior this may not be true because some may complete the purchase off-line.  Also, models believe that if one clicks on a link and makes a purchase, it is all due to that advertisement.  Other models that consider users who have been exposed and those that have not been exposed when generating typical purchase behavior may be inducing bias because the results while factual may correlate with other variables that could be statistically significant but have not been taken into consideration leading to unobserved heterogeneity. It is important to remember that for established brands people might be using click through rates as substitutes for other methods that people would be using to navigate to the site.  Also, it is important to remember for those stores that are brick and mortar, people often use the web to do their research and then will make their purchases at the storefront.  This will induce a negative return on investment when comparing online advertising to online purchasing.  This study indicates that if people are shown an ad or a placebo, people that are shown a placebo are still more likely to take an action based on their browsing activity during the time frame.  Effective time groups for an ad are normally 1-4 weeks, after that the data begins to decay and ads noise to the results.  One of the problems with these studies is small control groups in order to minimize costs. 

On-line advertising has opened up the doors for another method of discrimination.  As part of a screening process for job applicants, potential employers will often search in Google or on another search engine for the name of the applicant.  It seems that for names that are more likely to be associated with someone of African American descent, ads with a negative connotation are showed.  More specifically, it appears that ads that indicate that a person might have had a criminal background are delivered more often for names that would be associated with someone of African American descent than with a name that would typically be associated with a Caucasian.  Names were selected that were thought to be associated with African Americans (both sexes) and Caucasians (both sexes).  In order to validate the name selection, the names were searched and then images that were associated with each name were viewed.  The selected examples were then searched to see which advertisements were served, it was indeed more likely that those indicating an arrest showed for names associated with African Americans.  How is this selection done, who dictates that the ads show up for certain “racially associated names”? As compared to text ads which are seen and viewed the same by everyone, on-line ads can target based on history and indicative information that is provided by the user.  Online discrimination can have negative implications which people will complain about.  However, are also going to view media that is enjoyed and targeted to them based on the same parameters as discrimination or will they be thankful for it.  Unfortunately, these ads are probably based on a combination of statistics and intuition.  While it may not be acceptable to target people with ads that have negative connotation, by restricting what can be targeted or used as key words, half of the benefit of using on-line marketing is eliminated.  Discrimination is a slippery slope; targeting older people with certain ads could be age discrimination.  I think that one of the best things to do would be to educate people on the capabilities of on-line marketing and make them aware of such practices.  

The Google Analytics Fundamentals course was much more time consuming than it was supposed to be.  However, in order to watch all of the videos and complete all the tests it needed to be.  It was very nice though that the Google Analytics Platform Principles did not take nearly as long to complete and that it did not go into as much detail.  It was a good overview that helped sum up and simplify all of the details that were exposed in the first assignment. 
In Google Analytics, you are able to filter out the data that is contributed from employees, that way the data is not skewed.  Google Analytics also enables you to import data from multiple Google interfaces and other non-Google sources.  It also provides the ability to load it directly to third part reporting systems. However, reported data is only as good as the collection, configuration, and processing allow it to be.  Website users are tracked in a hierarchy of visitors, sessions, and interactions.  Processing and configuration work in conjunction with each other to make data valuable.   One of the most important things about Google Analytics is that once a filter is applied and data is collected, the data that is excluded cannot be pulled in for analysis.  If our client were able to apply Google Analytics, we would have to include the tracking information on every page in her web page that we wished to track.  If we did not, it would not record and store the data for those pages.  However, right now as our client has not successfully been able to turn on Google Analytics, this will not do much good for us right now.  Being that I work with data and large data tables every day and know how to filter or use pivot tables to analyze my data, these lessons have taught me that it is better to collect data for everything and worry about sorting it later.  It is also important to remember that results are only as good as the data that is collected and used, it is essential to know that the data you are collecting and using to make results is truly indicative of the process.

It was interesting to learn about the different types of cookies and their capabilities. Different cookies have different purposes and different expiration times. Some cookies are able to identify unique individual visitors to site and they are able to track their tendencies while surfing the web page.  These are first party cookies, the ability to track unique visitors enables web-sites to count new visitors or returning visitors.  First party cookies are cookies that are unique to that browser and cannot be shared across browsers; furthermore, cookies can only be read by the web site that created them.  Temporary cookies are another type of cookie and expire as soon as a browser is closed. Session identifier cookies have a 30 minute time out length and will time out if a visitor is inactive for 30 minutes.  Cookies are very helpful in customer visitor segmentation, it enables web-sites to pin-point certain demographics and their tendencies. The use of cookies and tracking, while it serves its purpose for the company, I am not sure if I would want a company to have a cache of information on had that it can use to target me for advertisements.  This could be potentially good to target potential terrorists if there are known web-site frequented by known terrorists.

Google uses two main types of targeting on the GDN or Google Display network: content and audience.  The methods of targeting for content are: keyword, topic, placement, and reserve.  Audience targeting includes remarketing and interest targeting.    Different types of targeting are used to fulfil different goals with different budgets.  Topic, placement, and reserve all work to achieve awareness goals, including broad reach impressions at a low cost.  Interest categories align with an audience’s infinities; messages are served to audiences based on their interests.  Remarketing reminds a customer of their started process until they finally come back and convert. Remarketing will serve display ads based on a user’s previous visits.  Topic targeting is where advertisers can target specific topics which best align with their goals and objectives, it is the broadest of content-based targeting types. Google technology reads pages in the display network and categorizes them into over 1,500 topics to enable precise targeting.  Advertisements are then targeted across selected topics to maximize traffic to a broad audience.  There are also over 700 geographical categories including region, country, and city level.  This type of targeting is good for branding campaigns which need to ramp up quickly; however, it is associated with higher cost per conversion and higher conversion rates. While it is fantastic that I am being shown items that I am almost always interested in, I think that I disagree with how targeted it is and how much they know about my thought process. It is funny how when I abandon an on-line shopping session with items still in my basket, a coupon shows up in my e-mail about two days later.

The study by Ghose and Yang examines the relationships between keywords, positions of the advertisements, and landing page quality score.  According to their work, keyword rank has a negative association with click-through rates and conversion rates.  An increase in the landing page quality score is associated with an increase in conversion rates.  Consequently, cost per click is negatively associated with the landing page quality score.  Their work also showed that ads that show up in the middle of the page get the greatest return from their investment, because they are not paying so much that it eat all their profit and they are not paying so far down the page that they do not receive any clicks.  One of the findings of their study disagrees with previous assumptions; it shows a negative relation between conversion rates and rank.  This means that the value per click to advertisers is not uniform across position; the previous assumption was that the value of a click was independent of the advertisement’s position. Their study also indicates that people will make a general un-branded search in order to gain information, they will then search for a branded item, once they know that they plan to buy that item, they will search for the item and try to figure out where they want to buy it from.  

This section of the class was very helpful to piecing different portions of reading together to learn how they interact and help influence marketing decisions.  After listening to the presentations on cookies, it helped to understand how Google uses cookies to observe factors which they include in their page rankings.  They also include this data in their Google analytics in order to identify new customers, this could be very helpful when trying to pinpoint the typical behavior of new customers to their site.  This would also be helpful when identifying where or why customers drop off without converting.  The Google power point showed the different methods of targeting consumers and which methods are best for certain situations and the type of campaign.  Topic targeting is one of the most effective methods for reaching consumers because of the volume that it can reach through impressions.  The volume of consumers that can be reached versus the costs of each impression leads to economies of scale using this method.  The study by Ghose and Yang further highlighted the inter-connectivity between search terms, bid price, consumer tendencies, and web-site design.  The moral of the story is that a lot of money could be spend on advertising, but if the web-site is not well designed including content and ability to convert, more money will be spent on advertising and fewer profits will be realized because more money is being spent on advertising and less profits are being achieved through conversions.
