In my moments of geofumar about the immortality of the toad and sharing with friends who understand this issue, we have concluded that Google knows how to control that a few days you earn less, others more, you have fewer visits ... and aspects like that .
On certain days, Google seems to shut down some servers for some specific regions, since we can see big spikes in visitors coming from search engines, known as “keywords”. It is likely that Google's facilities worldwide, where thousands of servers are located, are segmented according to areas where the greatest number of visits come from, which index better or worse depending on the results produced to AdWords clients accordingly. to trends (Trends) of greater influence.
The strange thing is that these peaks are not reflected in the same way to the income, so although it is a high traffic, it seems to be of low performance ... as experiments that the scientist is doing with the guts of the mouse.
Everyone will have noticed that there are not three good days in AdSense, some days when there are outstanding peaks are followed by falls that apparently "compensate" that good income, and those peaks are never that extreme. So that many say that Google knows how much we should earn, therefore when we should grow and be careful… when someone overcomes that pattern in apparent fraud of their policies.
In my opinion, Google has parameters of their AdWords ads, based on levels of campaign effectiveness in both income and clicks, and thus also has a robotized routine, in which if a blog exceeds in a certain day a percentage of anomalous growth, the next day receive announcements of a lower level of effectiveness, then up, down, until a certain stable trend is maintained.
Equally there must be parameters of penalization towards unhealthy practices, among which the wiggles are included, after which we have seen pagerank falls, or drop visits from search engines.
The consumption of AdWords
Here ... do what you want, observe this day, having an established daily budget, in which I pay just a penny per visit, suddenly many ads come even knowing that it is not an attractive value to have that level of efficiency in a Only day ... and mostly from Argentina.
So I could assume that Google closed the ads on this topic to many blogs and directed them to a region where I was experiencing a fall ... all at the expense of my liver.
It seems that Google could be even more effective in making users have better search results ... which would make us have more visits
... although that does not guarantee that we will have a faster growth than we have experienced.
Either way it's good to know, that last month that revenues “apparently” fell because Google sent our ads to their spaces… they are being compensated now.
