At the recent Search Engine Strategies conference in freezing Chicago, many of us Googlers were asked questions about duplicate content. We recognize that there are many nuances and a bit of confusion on the topic, so we'd like to help set the record straight. Duplicate content generally refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Most of the time when we see this, it's unintentional or at least not malicious in origin: forums that generate both regular and stripped-down mobile-targeted pages, store items shown and -- worse yet -- linked via multiple distinct URLs, and so on. In some cases, content is duplicated across domains in an attempt to manipulate search engine rankings or garner more traffic via popular or long-tail queries. Though we do offer a handy translation utility , our algorithms won't view the same article written in English and Spanish as duplicate content. Similarly, you shouldn't worry about occasional snippets quotes and otherwise being flagged as duplicate content. Our users typically want to see a diverse cross-section of unique content when they do searches.
Why we're making this change
What is HTTP/2
As we said, it's the next major version of HTTP , the protocol the internet primarily uses for transferring data. In general, we expect this change to make crawling more efficient in terms of server resource usage. With h2, Googlebot is able to open a single TCP connection to the server and efficiently transfer multiple files over it in parallel, instead of requiring multiple connections.
