Some changes in its algorithm, on a regular basis is something that Google has accustomed us. Every month, Google seeks to keep improving search results and will neutralize "shortcuts" that take some SEO, and refine the results. But this time, the change has been dramatic and as Google itself, affects 12% of the results of the search pages.
The purpose of the change is to lower the positioning of pages devoted to copy or add mass content of others, without contributing anything new, then include in your site a large number of ads Google or other affiliate programs.
The truth is that the network began to be flooded with pages whose sole purpose was to show ads (which on the other hand, the vast majority were from Google itself). In many cases these pages, original content, and riddled with advertising, appeared in the top of the searches because their creators, aware of all SEO techniques, had managed to make it so. In English this kind of page is called "Adsense farm". Hence this is the algorithm update has popularly dubbed the "Adsense Farm Update”.
According to Google, its engineers have been working for over a year to find a way to neutralize the strength of these web pages, and it seems that with the new algorithm lon has achieved ... The question that arises now is how exactly has been modified the algorithm and what Google is taking into account when determining whether a site has original content or not.
Compare indexes created from scanning pages is already what he was doing at the moment when discern what was considered duplicate content (and punishable) and what not. But when one copy only part of a page, he included in his, and fill the rest with ads, is something that is not detectable from the simple comparison of indices simply why the word list that includes the page is different and original about that you copied. So Google has had to find another way to do it.
By reading forums SEO parece que el resto de profesionales están también preguntándose qué es lo que ha cambiado exactamente, y aunque especulan sobre diversas posibilidades, ninguna parece concluyente. En algunos casos, incluso ha cundido el pánico entre gente que practicaba el Adsense Farming y algunos indican que han perdido un 40% de su tráfico.
Desde mi punto de vista, lo más lógico sería que el cambio consistiese en que ahora Google es capaz de reconocer párrafos enteros (no palabras sueltas) que han sido publicados en otros sitios, y puede conocer qué contenido fue indexado primero. También me parece lógico pensar que Google sabe perfectamente cómo reconocer el código fuente de páginas web que son granjas de Adwords (precisamente porqué el código es suyo) y por lo tanto puede hacer énfasis en el control del contenido de este tipo de páginas.
In any case, we are not doing these practices can be calm because this change should not adversely affect, if not the opposite. Our websites should gain positions on the search results pages.
Hopefully a few days, see if someone manages to decipher the change and discovered exactly what it is.
