Each day, Google usually releases one or more changes designed to improve our search results. Most aren't noticeable but help us incrementally continue to improve. Sometimes, an update may be more noticeable. We aim to confirm such updates when we feel there is actionable information that webmasters, content producers or others might take in relation to them. For example, when our "Speed Update" happened, we gave months of advanced notice and advice. Several times a year, we make significant, broad changes to our search algorithms and systems. We refer to these as "core updates.
Do I still need to flag ad or sponsored links?

Nearly 15 years ago, the nofollow attribute was introduced as a means to help fight comment spam. It also quickly became one of Google's recommended methods for flagging advertising-related or sponsored links. The web has evolved since nofollow was introduced in and it's time for nofollow to evolve as well. Today, we're announcing two new link attributes that provide webmasters with additional ways to identify to Google Search the nature of particular links. These, along with nofollow , are summarized below:. When nofollow was introduced, Google would not count any link marked this way as a signal to use within our search algorithms. This has now changed. All the link attributes— sponsored , ugc , and nofollow —are treated as hints about which links to consider or exclude within Search.

Trust Flow represents the quality of links that point to URLs and websites. A web page with higher Trust Flow than Citation Flow will usually have good-quality links. Citation Flow is a score which reflects the quantity of links that point to any given website. Citation Flow does not care whether a link is of good-quality, or poor quality. The Visibility Flow score helps you to find desirable editorial-style links on high Trust Flow pages, rather than directory-style links even when the directory Trust Flow is high. With a score that shows where a website is positioned compared to the very best sites in over categories, Topical Trust Flow illustrates the topical relevancy of a web page.
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.
