As anyone knows Google recently announced a new addition to their Trends tools called “Google Trends for Websites”. you can use it to see traffic estimates, related sites, and related searches for websites (it looks like Alexa but more lovely).
So we wrote some parameters to use it in SeoQuake -

G trends (month)
[NAME]=G trends (month)
[TITLE]=G trends
[URL_R]=http://trends.google.com/websites?date=mtd&q={domain}
[REGEXP]=chm\=.*\+([\d.]+\+\w).*chg\=
G trends (Year)
G trends up limit(month)
G trends up limit (Year)
You can get them here - http://addons.seoquake.com/params/index.php?sln=en&browse=2&tag=google&res_lim=10
Remember, you should be logged in you google account to recive this data from Gtrends.

In recent years context advertising has been growing rapidly. Nevertheless, there is little independent information on prevalence of different context advertising systems. Even worse, the owners of such systems often conceal information about how many participants and websites are registered in the system, or how much traffic the system generates.
This overview sheds light on the prevalence of different context advertising systems on the web.
Why we did it (Research Objectives)

• Assessing the prevalence of main contextual advertising systems
• Understanding the number of participants and web sites in each system.

What we did (Experiment Design)
The first stage was preliminary testing. We took top-10K sites as rated at Alexa.com and top-10K sites as rated at SeoDigger.com . From each site we downloaded the main page and three internal pages. After that we identified contextual advertising systems present on these sites.
Among them the most frequently found were: AdBrite, Google AdSense, Yahoo Partner Network, Chitika, Amazon Context, Kontera. During the initial screen we found that MSN and IntelliTXT systems were very rare and therefore they were excluded from further analysis.
For the second stage we took 20 million of the most poplar domains according to the SeoDigger rating. Five million domains were randomly selected out of them. Then a special crawler processed the sample domains, and downloaded the main pages and 3 internal pages from each site. The data were parsed to determine the presence of contextual advertising codes. We collected the following information: domain name, system name and user ID. The results were loaded into the database and analysed.
What we found (Results)

Out of the 5 million sample 318,313 domains had advertising. The total number of accounts amounted to 182,902. The number of domains per system is shown in Table 1, while the number of accounts per system is shown in Table 2.

Please note that system share was calculated as percent of the systems included in the research. Thus it represents the share of systems to each other, not to the market as a whole. Some contextual advertising systems (the ones with small shares, or local) were omitted from calculations.

The leader in terms of the number of sites collaborating with the system is AdSense. 96% of all sites that take part in a contextual advertising partnership system use Google AdSense.
Number of accounts per system


The maximum number of accounts belongs to AdSense (95%), AdBrite follows. Each of the remaining systems has roughly 1% of accounts.
The activity of webmasters

The maximum activity of participants (understood as a ratio between the number of domains and the number of accounts) was registered in the AdSense system. YPN is following.
The distribution of systems for the top level domains zones.


Most codes were found in the .com zone. This is because this is the biggest and fastest growing zone. The maximum activity of webmasters (domain to account ratio) was observed in zones .info (due to low cost of domain registration) and .de (due to the webmasters’ activity with AdSense). High rates of webmasters’ activity in the .nl zone can be explained by the large number of third level domains belonging to one account. If we exclude this account from calculations, domain to account ratio for this zone becomes 1.3.


It was interesting to look at .us, .mil, .gov, .edu domains in terms of contextual advertising.The highest number of sites with contextual advertising was detected in the .us zone (1252 domains, 93% AdSense), followed by . edu (63 domains, 100% AdSense ). In the .gov zone only one site with advertising was found (AdSense), whereas in the .mil zone we found no sites with advertising. In most domain zones share AdSense is 93% and higher, with the exception of the .ru zone.

In the .ru TLD Google has a strong local competitor - Yandex.ru, which has its own contextual advertising system Yandex.Direct. According to our estimates the ratio of AdSense accounts to Yandex.Direct accounts is roughly 2 : 1.

Some Interesting Facts
Maximum number of domains per one account in the system
AdSense is the leader here. The code of each of the three accounts-leaders is displayed at more than 1000 domains. Out of these one account belongs to a virtual hosting provider and appears on page 404. The second one belongs to free hosting and is displayed on pages hosted at this hosting. The third belongs to a network of sites made specifically for display AdSense.

More than 100 domains at one account was found only among AdSense-accounts. Top 50 places sorted by domain-to-account ratio belong to AdSense accounts (each of them is placed more than on a hundred domains). There are only two non-Google AdSense accounts in the top-50 which belong to Kontera. One of them is placed at 80 different sites at free hosting, while the second user has 69 sites in the .tk zone.
One account that stands out from the rest is AdSense test account with ID pub-xxxxxxxxxxxxxxxxxx. It is placed and works at 69 sites at least, some of which are visited by more than 3000 people a day. Observation during several weeks has shown no sign of changes in the codes, and it remains obscure who benefits from clicks on these ads.
Sites with the maximum number of accounts per site
Some sites allow users to add their advertising codes. The leaders of our ranking in this category are as follows:

At forums.digitalpoint.com we found 1798 unique codes of Google AdSense.
We found more than 1500 sites with codes of three and more advertising systems.
Conclusion
It can be concluded that the majority of webmasters (95%) prefer Google AdSense that dominates the international market of contextual Internet advertising except some local markets ( .ru and a few other TLD). In addition, participants of this system are the most active.
Limitations
Because, the domains for analysis were selected from the SeoDigger.com rating, which is based on Google’s data, there might be slight inconsistencies in results. In theory, Google could give preference to sites with AdSense. However, there is no evidence of this to date.
Future research possibilities: We plan to assess the amount of traffic passing through each system, index more sites to refine the calculations and analyze the prevalence of other advertising systems.
Services through which a study was conducted:
http://AdsSpy.com collects information about 9 contextual advertising systems, over 400K domains and 200K accounts.
http://SeoDigger.com collects information about sites positions in 60 million search queries.
