Schimbare de algoritm Google privind siteurile care fac scraping

[Nic]

Matt Cutts spune ca saptamana asta google a implementat o schimbare de algoritm cu scopul de a ranka mai slab siteurile care fac scraping si care nu au continut original.

"Earlier this week Google launched an algorithmic change that will tend to rank scraper sites or sites with less original content lower. The net effect is that searchers are more likely to see the sites that wrote the original content. An example would be that stackoverflow.com will tend to rank higher than sites that just reuse stackoverflow.com's content. Note that the algorithmic change isn't specific to stackoverflow.com though.
I know a few people here on HN had mentioned specific queries like [pass json body to spring mvc] or [aws s3 emr pig], and those look better to me now. I know that the people here all have their favorite programming-related query, so I wanted to ask if anyone notices a search where a site like efreedom ranks higher than SO now? Most of the searches I tried looked like they were returning SO at the appropriate times/slots now."

"This was a pretty targeted launch: slightly over 2% of queries change in some way, but less than half a percent of search results change enough that someone might really notice. The net effect is that searchers are more likely to see the sites that wrote the original content rather than a site that scraped or copied the original site’s content."

Interesant ca s-au miscat repede, cand auzisem stirile ca au de gand sa ia masuri, credeam ca sunt mai multe vorbe goale. Sa vedem daca fac ceva si cu adsense.

Ati observat ceva schimbari pe google.ro ? sau si pe .com?
