With AdSense they can also track the referrals which gives them another way to understand percent of market share and who your leading referals are if you display AdSense ads on your site.
their ad code shows:
google_referrer_url = document.referrer;
Google could likely use this data for their AdSense SmartPricing, fraud detection, and might even use it as an additional quality check on linkage data and sites.
If you link to a site participating in AdSense and nobody ever follows the link does that mean the link, page, or site could potentially have little to no value to humans?
If you have links from a ton of sites all using the same AdSense account could that be suspicious? If thousands of sites link to you and none of them dispay AdSense could that be suspicious?
It seems as though Google is trying to financially incentivize various webmasters in the concept of building its web of trust. Maybe it is part of the reason they don't mind having shoddy sites in AdSense, as it helps them track relationships?
Danny Sullivan also wrote an article (sub req) about how some large advertisers get additional SEO support from search engines.
Google is known to tell some large advertisers that it is OK to do things that are against their official webmaster guidelines.
If you selectively boost some sites it has the same net effect of manually penalizing or filtering others, which goes counter to that "democratic nature of the web" "we don't manually..." "don't be evil b/s."
The Google Budget Optimizerâ„¢ campaign management tool automatically adjusts your keyword Max CPCs on your behalf. All you need to do is set a target budget, and the Budget Optimizer will actively seek out the most clicks possible within that budget.
The Budget Optimizer helps you reach your target spend every month without requiring a lot of work on your part. You can save time, eliminate the guesswork related to setting your CPCs, and enhance your return on investment.
(Please note that the goal of the Budget Optimizer is simply to help you receive the highest number of clicks possible within your budget. The Budget Optimizer will not help you achieve a specific ad position.)
They certainly are going out of their way to make the ads as "self serve" as they possibly can. I do not manage many AdWords campaigns so I probably am not the best person to test this out, but it would be interesting to hear what effect this tool actually has on ROI.
With how far off Google is with day to day search volume / ad clickthrough suggestions it is interesting that they think people will trust a system which automatically adjusts bids for them based on a metric other than ROI. Of course some marketers do not want to share ROI data with Google.
I also believe that if a campaign is self funding there is no reason to put an arbitrary budget cap on it. Buy as many ads as you profitably can.
I am guessing that if you enable this feature you will want to enable it in ad groups where the keyword max CPCs and lead values are similar.
A group of advertisers quietly filed a lawsuit in February against Google Inc., Yahoo Inc. and other Internet companies in a potentially important legal test of those companies' liability for a form of online-advertising fraud.
The plaintiffs, led by Lane's Gifts & Collectibles LLC, a Texarkana, Ark., retailer, allege that the Internet companies knowingly overcharged for advertisements they sold and conspired with each other to continue doing so. The plaintiffs are seeking to have their suit, which hasn't received widespread attention, certified as a class action.
The also named AOL, Ask, Disney, Lycos, LookSmart, and FindWhat in the suit.
The search engines have antifraud systems and sometimes issue refunds for bogus clicks. But they decline to comment in detail on the scope of the problem, exactly how they are fighting it, and any specific instances of click fraud, in part because they don't want to tip off fraudsters. That has fed some advertisers' fears that the problem is bigger than the search companies acknowledge. Estimates of click fraud run as high as 20% of all clicks on search ads.
Yahoo! has been making a strong run in the stock market for the last week, and Google is valued at 49 billion. Nobody has really challenged this issue yet. If this gets pushed it could get rather ugly quick for search stocks. Google makes 99% of their income from ads.
The launch of the campaign was timed to coincide with the beginning of the Japanese financial year, said Saito. April 1 is typically the day that large Japanese companies take in new employees. It is also close to the beginning of the school and university year, so many people are starting "new lives" at around this time of year. With the campaign, Google wants to promote itself as a way for people to get information relevant to their new lives, said Saito.
One of the biggest benefits of search engine marketing and creating your own content is that you can create products, content, and ads based on when you expect people to be at inflection points in their lives. (link found from SearchViews)
